Getting Started With Your Wood-Fired Hot Tub

Your Tamed Ocean hot tub is designed exclusively for private outdoor use. Follow these guidelines for proper setup and installation:

Transportation & Initial Setup

Your hot tub arrives ready for installation. Here's what you need to know:

  1. Remove Pallet: Your hot tub is delivered upright on a pallet for protection. Remove the pallet before final installation
  2. Position Quickly: Bring the hot tub to horizontal position as soon as possible after delivery to prevent it from bending into an oval shape
  3. Lift Properly: Always lift the hot tub from the base, never by the edges or rim. Use at least 3-4 strong people for safe handling
  4. Inspect Upon Arrival: Check for any transport damage before the delivery driver leaves

Heavy Load: Wood-fired hot tubs weigh 200-250kg empty. When filled with water and occupants, total weight can reach 1,600-1,900kg. Plan accordingly!

Choosing the Perfect Location

Select a location that provides:

  • Level Surface: Essential for proper water circulation and structural integrity
  • Load-Bearing Capacity: Must support 1,600-1,900kg when fully loaded
  • Good Drainage: Area where drained water can flow away safely
  • Accessibility: Easy access for filling, draining, and maintenance
  • Privacy: Consider your comfort and neighbors' views
  • Scenic Views: Position to enjoy your garden or landscape

Preparing the Base

Proper foundation preparation is crucial for longevity and safety:

Base Options (in order of preference):

  1. Concrete Pad: Most stable option. Pour a level concrete slab at least 10cm thick, extending 30cm beyond hot tub edges
  2. Paving Slabs: Lay level paving slabs on compacted sand base. Ensure slabs are tightly fitted with no gaps
  3. Compacted Gravel: Minimum 15cm deep layer of compacted gravel, perfectly leveled. Less stable than concrete or slabs
  4. Reinforced Decking: Must be specifically engineered to support 1,900kg load. Consult structural engineer

Base Preparation Steps:

  • Remove Vegetation: Clear all grass, weeds, and plant roots to prevent growth under hot tub
  • Level Surface: Use a spirit level to ensure perfect levelness in all directions (critical for proper operation)
  • Drainage Slope: Slight slope away from hot tub prevents water pooling underneath
  • Weed Barrier: Lay landscape fabric beneath gravel or slabs to prevent weed growth

Ventilation & Protection

  • Ensure hot tub is not surrounded by tall grass or dense shrubs that restrict airflow
  • Proper ventilation prevents wood rot and moisture damage
  • If your hot tub has wooden substructure, keep it dry and well-ventilated
  • Avoid areas with constant shade or poor air circulation

Future Accessibility

Plan for potential maintenance needs:

  • Hot tub should always be relocatable if necessary
  • Even if embedded in a terrace, ensure you can remove it for repairs
  • Leave adequate space around hot tub for cleaning and maintenance access

Warranty Note: The warranty does not cover indirect costs such as dismantling or rebuilding a terrace, deck, or structure to access the hot tub for repairs.

Water Drainage

Your Tamed Ocean hot tub features a convenient drainage system for easy water removal:

Drain Valve Location

  • Primary Drain: 1" (25mm) ball valve located on lower right-hand side of the stove
  • Secondary Drain (if applicable): Additional drain in hot tub floor for 2-meter models with external stove

Drainage Considerations

When choosing your installation location, consider:

  • Natural Slope: Position hot tub where water can drain naturally away from the base
  • Drainage Destination: Ensure drained water flows to appropriate area (garden, drainage system, etc.)
  • Hose Connection: If using a hose for directed drainage, you'll need a 1" connection nipple (not included)
  • Volume: A full hot tub contains approximately 1,000-1,500 liters of water

Draining Procedure

  1. Cool Down: Ensure water has cooled to safe temperature and fire is completely extinguished
  2. Remove Thermal Cover: Take off the thermal lid and set aside on clean surface
  3. Open Ball Valve: Push safety device toward handle and open drain valve fully
  4. Direct Flow (Optional): Attach hose with 1" nipple to direct water flow if needed
  5. Complete Drainage: Allow water to drain completely (typically 30-60 minutes depending on flow)

Winter Precaution: In freezing conditions, all water must be drained from hot tub, connecting hoses, and stove to prevent ice damage. See winter care section for details.

Ball Valve Safety Device

All ball valves include a safety device preventing accidental opening or closing:

  • To operate: Push safety device toward the handle
  • Lever can then be moved freely between open and closed positions
  • This prevents children or accidental bumps from opening valves

Fire Safety

Proper fire safety measures are essential when operating a wood-fired hot tub. Follow these guidelines to prevent fire hazards:

Chimney Clearance Requirements

If your hot tub is near a building, terrace, or any structure:

ComponentMinimum ClearanceNotes
Chimney Top3 meters from flammable materialsMust be verified vertically and laterally
Chimney SidesVaries (consult local codes)Smaller distances permissible with insulated chimney
Roof Penetration1 meter above roofInsulated chimney section must extend minimum 1m above roof
Combustion Chamber AreaNo flammable materialsFront and beneath must be non-combustible only

Insulated Chimney Requirements

Use an insulated chimney (sold separately) when:

  • Prescribed safety distances cannot be maintained
  • Chimney passes near building walls or rooflines
  • Local fire codes require additional protection
  • Chimney penetrates through any structure

Important: If chimney is near roof or penetrates it, the insulated section must extend at least 1 meter above the roofline.

Combustion Chamber Area Safety

The area in front of and beneath the combustion chamber must contain only non-combustible materials:

  • Acceptable Materials: Concrete, sand, stone, metal plate, fire-rated tiles
  • Prohibited Materials: Wood, composite decking, vinyl, grass, leaves, paper, or any flammable material
  • Clearance Zone: Maintain at least 1 meter clearance in front of stove door

Hot Surface Warnings

During operation, certain components become extremely hot:

  • Stove Hood: Reaches very high temperatures—can cause severe burns
  • Stove Hatch/Door: Extremely hot during firing—use heat-resistant gloves
  • Chimney: Entire length becomes hot during use
  • Outlet Pipe: Hot water flows from stove outlet—risk of scalding

Child Safety: Keep children away from stove, chimney, and hot tub during heating. Establish a safety zone at least 1 meter around the combustion chamber.

Local Fire Safety Compliance

Fire safety requirements vary by location. Always:

  • Consult your local fire safety authority before installation
  • Comply with all building codes and fire regulations
  • Maintain required clearances from property boundaries
  • Consider installing smoke detectors in nearby areas
  • Keep fire extinguisher accessible near hot tub area

Connecting the Wood-Fired Heater/Oven

Proper connection of the outdoor oven to your hot tub is essential for efficient heating and safe operation:

Positioning Requirements

Critical: The outdoor oven and hot tub must be positioned on the same level. Height differences will prevent proper circulation.

Connection Hose Setup

Your hot tub uses two connection hoses between the stove and tub:

Upper Connection Hose:

  • Hot Water Outlet: Carries heated water from stove to hot tub
  • Must Run Diagonally Upward: This angle is essential for proper thermosiphon circulation
  • No Dips or Loops: Hose should maintain upward angle without sagging
  • Secure Connections: Ensure clamps are tight at both ends

Lower Connection Hose:

  • Cold Water Inlet: Returns cooler water from hot tub bottom to stove
  • Can Run Directly: This hose may run straight or with slight slope
  • Shortest Path: Keep as short as practical while allowing access
  • Avoid Kinks: Ensure hose isn't pinched or compressed

How Thermosiphon Circulation Works

Your wood-fired hot tub uses natural convection (thermosiphon principle):

  1. Cold Water Descends: Cooler, denser water naturally sinks to the bottom of the hot tub
  2. Enters Stove: Flows through lower hose into the bottom of the wood-fired stove
  3. Heats in Stove: Fire heats the water as it passes through the stove's heat exchanger
  4. Hot Water Rises: Heated water becomes less dense and rises through upper hose back into hot tub

This natural circulation continues automatically as long as the fire burns—no pumps or electricity required!

Why Proper Angle Matters: The upward angle of the upper hose assists the natural flow of hot water. A downward dip would trap air and prevent proper circulation.

First Use Preparation

Before first use, flush the water circuit:

  1. Prepare Hose: Have a garden hose ready with good water pressure
  2. Spray Top Pipe: Insert hose into topmost pipe of stove and spray ample water through system
  3. Flush Residues: This removes manufacturing residues, dust, and debris from internal surfaces
  4. Remove Debris: Any dirt accumulating in hot tub bottom can be scooped out
  5. Check for Leaks: While flushing and during first heating, check all connections for leaks

Ongoing Leak Checks

During operation, periodically inspect:

  • Connection hose clamps—ensure they remain tight
  • Hose condition—check for cracks, wear, or degradation
  • Connection points—look for drips or seepage
  • Water level in hot tub—significant drops may indicate leaks

Do Not Connect to Circulation Pump: The furnace is designed only for automatic gravity circulation (thermosiphon). Do not connect it to powered circulation pumps.

Filling Your Wood-Fired Hot Tub

Proper filling is essential for safe operation and heating efficiency. Follow these guidelines carefully:

Before You Fill

Critical Check: Ensure the drain ball valve is completely closed before filling. An open valve will drain water as you fill!

Determining Fill Level

The amount of water needed depends on expected occupancy:

  • Maximum Occupancy: Fill to minimum level—more people displace more water
  • Solo or Couple Use: Can fill higher for deeper soaking experience
  • Balance: More water takes longer to heat but stays warm longer

Minimum Fill Level (CRITICAL)

NEVER heat with insufficient water! The hot tub must ALWAYS be filled to at least 5cm (2 inches) ABOVE the upper connecting pipe of the oven before firing the stove.

Why this matters:

  • Water-filled oven prevents furnace damage
  • Insufficient water allows stove to overheat and melt
  • Damage from dry-firing is immediate and irreversible
  • Dry-firing voids warranty

Filling Process

  1. Close Drain Valve: Ensure ball valve is fully closed and safety device is engaged
  2. Begin Filling: Use garden hose with clean, potable water
  3. Monitor Level: Watch upper connection pipe—water must cover it by at least 5cm
  4. Check Connections: As water rises, check all connection points for leaks
  5. Adjust for Occupancy: Fill to desired level based on expected number of users

Water Source Considerations

  • Tap Water: Ideal—already treated and safe
  • Well Water: May require additional filtration or treatment
  • Rainwater: Not recommended unless properly filtered and treated
  • Water Quality: Poor quality water may require more chemicals to maintain hygiene

Initial Water Treatment

After filling with fresh water:

  • Test pH level (target 7.2-7.8)
  • Add initial sanitizer if planning extended use
  • Allow chemicals to circulate (stir manually if no circulation system)
  • Wait 20-30 minutes before lighting fire

Cold Weather Precautions

Frost Protection: The water-filled oven must not freeze in winter. Before freezing temperatures:

  • Either empty the hot tub completely, OR
  • Ensure sufficient heating of water to prevent freezing, OR
  • Bring hot tub indoors or to heated space

Ring Clamp Adjustment

Your hot tub features two ring clamps (19mm) on the outer edge near the furnace:

  • Purpose: Tighten stainless-steel bands around wooden staves
  • When to Use: If wooden boards loosen during drying
  • How to Adjust: Use 19mm wrench to tighten gradually
  • Warning: Don't over-tighten—this can crack or damage wood

Wood Swelling: Wood naturally expands when wet and contracts when dry. Minor adjustments with ring clamps are normal during first few uses.

Lighting the Stove & Heating Your Hot Tub

Operating your wood-fired stove is straightforward and rewarding. Follow these guidelines for efficient, safe heating:

Before Lighting: Confirm water level is at least 5cm above upper connection pipe. NEVER light an empty or insufficiently filled hot tub—this will melt and destroy the furnace!

Fuel Selection

For optimal performance and minimal smoke:

Recommended Fuel:

  • Dry, Seasoned Hardwood: Oak, ash, beech, or similar dense woods
  • Split into Small Pieces: 5-10cm diameter, 25-35cm length
  • Moisture Content: Below 20% for best results (seasoned 1-2 years)
  • Quantity: Approximately 10-15kg per heating session

Prohibited Fuels:

  • Coal or Charcoal: Excessive heat can damage stove
  • Treated/Painted Wood: Toxic fumes and chemical damage
  • Wet or Green Wood: Creates excessive smoke and doubles heating time
  • Garbage or Plastics: Toxic emissions and stove damage

Lighting Procedure

  1. Prepare Kindling: Gather small, dry twigs, wood shavings, and fire starters (lighter cubes or paraffin bags recommended)
  2. Build Base Layer: Place fire starter in center, surround with small kindling in teepee or log cabin structure
  3. Light Fire: Ignite fire starter, ensuring good airflow. Open air supply fully for initial burning
  4. Add Small Logs: Once kindling is burning well (5-10 minutes), add small split logs gradually
  5. Increase Size: Every 10-15 minutes, add progressively larger logs as fire establishes
  6. Maintain Hot Fire: Keep stove fully heated with strong flames for maximum heating power

Heating Times

Typical heating duration from cold water (15°C) to bathing temperature (38°C):

  • Tarkine (1.8m): 1.5-2 hours with good fire
  • Daintree (2.0m): 2-2.5 hours with good fire
  • Poor Fire: Can double heating time—keep fire strong!

Using the Thermal Cover

  • During Heating: Keep thermal cover on to minimize heat loss and reduce heating time by 30-40%
  • Before Bathing: Remove cover 5 minutes before entering to let water "breathe"
  • After Use: Replace cover quickly to retain heat and maintain temperature
  • Next-Day Use: If planning to use tomorrow, maintaining cover keeps water warm longer

Temperature Monitoring

Critical: Water Stratifies! Hot water rises to top while cooler water remains at bottom. Always stir water thoroughly before measuring temperature to get accurate reading.

Temperature checking procedure:

  1. Check Every 20 Minutes: Especially as temperature approaches 35-40°C range
  2. Stir First: Use your hand, paddle or turn on jets or air system to mix water layers throughout tub
  3. Measure in Center: Place thermometer mid-depth in center of tub
  4. Wait for Reading: Allow thermometer to stabilize (30 seconds minimum)

Temperature Management

  • Below 30°C: Add wood freely to build heat
  • 30-35°C: Reduce wood quantity, maintain steady fire
  • 35-38°C: Add small pieces only, monitor closely
  • 38-40°C: Minimal wood, let existing fire burn down
  • At Target Temp: Maintain small fire to sustain temperature

Pro Tip: As water reaches 32-35°C, use less wood to prevent unnecessary overheating. It's easier to maintain temperature than to cool down overheated water. If overheated filling more cold water would be the quickest solution

Adjusting Air Supply

Control burn rate and reduce smoke with air supply adjustment:

  • Fully Open: Use when lighting and building initial fire
  • Three-Quarters Open: Normal operation during heating phase
  • Half Open: When approaching target temperature
  • Quarter Open: Maintaining temperature with small fire

Condensation in Combustion Chamber

Don't worry if you see moisture:

  • Condensation forms due to temperature difference between cold water and warm air
  • This is normal physical effect, not a leak
  • Will stop once stove and water warm up
  • Significant water level decrease would indicate actual leak

Safety Warnings During Operation

  • Hot Water Outlet: Hot water (60-80°C) flows from stove outlet—risk of burns!
  • Hot Surfaces: Stove hood, door, and chimney become extremely hot—don't touch!
  • Open Flames: Keep children and pets away from stove area
  • Unattended Fire: Never leave burning fire completely unattended

After Each Use

  • Let Fire Burn Out: Allow fire to extinguish completely before leaving
  • Empty Ash Pan: Remove ash from ash pan and combustion chamber once cool
  • Replace Cover: Put thermal lid back on to maintain heat and keep debris out
  • Clean Grates: Remove ash buildup from grates for next use

Consumable Parts: Grates and air flaps are consumable items subject to normal wear from heat and use. These are not covered by warranty and will need periodic replacement.

Never Empty Hot Tub While Fire Burns

Critical: Do not drain the hot tub before fire has completely extinguished and embers have cooled. Removing water while stove is hot will cause catastrophic damage!

Recommended Water Parameters

ParameterIdeal RangeAcceptable Range
pH Level7.4-7.67.2-7.8
Free Chlorine3.0 ppm1.0-5.0 ppm
Total Alkalinity80-100 ppm40-120 ppm
Calcium Hardness (Standard)100-125 ppm75-150 ppm
Calcium Hardness (Salt Systems)50 ppm25-75 ppm

pH Level: The Foundation of Water Chemistry

Maintaining proper pH is absolutely critical. Here's why:

pH Too Low (Acidic, below 7.0):

  • Corrosion of metal components (stove, fittings, fasteners)
  • Skin and eye irritation
  • Rapid chemical consumption
  • Damage to hot tub surfaces

pH Too High (Alkaline, above 7.8):

  • Reduced sanitizer effectiveness
  • Cloudy water and scaling
  • Calcium deposits on surfaces
  • Skin and eye discomfort

Monitor pH Constantly: Test pH level at least 2-3 times per week when hot tub is in use. Chemical use often causes pH to drop, which can corrode hot tub components!

Chemical Dosing Guidelines

Always follow manufacturer instructions on product packaging. General guidelines:

Prohibited Tablet Types:

Do Not Use: Trichlorine-based tablets or large tablet combinations are prohibited. These can overdose and cause severe corrosion.

Exception: Small 20g tablets are acceptable as their concentration cannot rise excessively.

Proper Chemical Application:

  • Use Dispenser: Tablet chemicals must always be dissolved with a floating dispenser
  • Never Drop Tablets Directly: Undissolved tablets sitting on surfaces cause localized corrosion and bleaching
  • Granular Chemicals: Pre-dissolve in bucket before adding to hot tub
  • Add When Empty: Preferably add chemicals when hot tub is empty of bathers
  • Wait Before Use: Allow 30 minutes circulation time before entering after chemical addition

Automatic Chemical Dosing Devices

Caution with Automatic Dosers: Swimming pool chemical dosing devices should not be used with wood-fired hot tubs. These devices often lead to overdosing and material corrosion.

If you must use automatic dosing:

  • Must be constantly monitored and adjusted
  • Test water parameters daily
  • Use lowest possible dosing settings
  • Designed specifically for hot tubs (not swimming pools)

Filter Systems

To extend water life and maintain cleanliness:

  • Combination Approach: Use chemicals AND filtration together
  • Regular Cleaning: Clean filter cartridges weekly during heavy use
  • Filter Replacement: Replace filter cartridges every 12-18 months
  • Run Schedule: Run filter 4-8 hours daily during use periods

Water Testing Schedule

  1. Before Each Use: Quick test of chlorine and pH levels
  2. 2-3 Times Weekly: Full test strip or liquid test kit
  3. After Heavy Use: Test immediately after large gatherings
  4. After Chemical Addition: Retest 30 minutes after adding chemicals

Exhibition or Display Use

Important: If hot tub is filled with water for exhibition or presentation purposes (even without use), the water must always be chemically treated to prevent bacterial growth.

Professional Water Care Supplies

For comprehensive water care products and guidance, inquire at specialist pool and spa supply stores. They can provide:

  • Appropriate chemicals for your hot tub size
  • Testing kits and supplies
  • Filter options
  • Expert advice on water balance

Hygiene for Hot Tubs Without Filter System

If your wood-fired hot tub does not have a filter system or other water exchange mechanism, stricter hygiene protocols must be followed:

Important Limitation: Without filtration, water should only be used for one bathing session and then drained. Extended water retention without filtration poses health risks.

Maximum Water Lifespan

Strict time limits apply based on water source:

Using Drinking Water (Potable Water):

  • Maximum Lifespan: 5 hours from filling
  • Water Source: Must comply with drinking water regulations of your country
  • Single Session: Fill, heat, use once, drain
  • Temperature Matters: Clock starts when water enters tub, not when heating begins

Using Untreated Water (Non-Potable):

  • Maximum Lifespan: 3 hours from filling
  • Water Source: Well water, rainwater, or other non-drinking sources
  • Higher Risk: Bacterial growth occurs faster in untreated water
  • Not Recommended: Use potable water whenever possible

Why These Limits? Warm water (36-40°C) creates ideal conditions for rapid bacterial growth. Without filtration or chemical treatment, dangerous bacteria can multiply to unsafe levels within hours.

Single-Use Protocol

For hot tubs without filtration, follow this procedure:

  1. Fill Fresh: Fill hot tub with clean water immediately before use
  2. Heat Quickly: Light fire and heat water to bathing temperature
  3. Use Once: Enjoy your bathing session (limit to recommended time)
  4. Drain Immediately: Drain all water completely after use
  5. Clean Interior: Rinse hot tub interior with fresh water
  6. Dry Completely: Allow hot tub to dry before next use

Chemical Treatment Option

If you wish to extend water life slightly:

  • Add appropriate sanitizer (chlorine or oxygen-based) after filling
  • Maintain pH in correct range (7.2-7.8)
  • Still limit to single bathing session
  • Drain after use—chemical treatment doesn't replace filtration

Health Risk: Even with chemical treatment, water without filtration should not be reused for multiple sessions. Bacterial contamination, body oils, and debris accumulate rapidly.

Hygiene Best Practices

To minimize contamination risks:

  • Shower First: Everyone should shower before entering hot tub
  • No Illness: Do not use if anyone has infections, open wounds, or is feeling unwell
  • No Submerging Heads: Keep faces above water to reduce exposure
  • Limit Bathers: Fewer people = less contamination
  • Drain Promptly: Don't leave water sitting overnight

Consider Adding Filtration

If you use your hot tub frequently, consider upgrading:

  • Cartridge Filter System: Most cost-effective option
  • Sand Filter: Low maintenance, effective filtration
  • Combination Systems: Filter plus UV or ozone for enhanced sanitation
  • Contact Tamed Ocean for filtration upgrade options

Investment in Health: Filtration systems allow extended water use (7-14 days), reduce water waste, and provide safer, cleaner bathing experience. Well worth consideration for regular users.

Maintenance of Hot Tubs with Hydro or Air Massage Systems

Hot tubs equipped with hydro massage or air massage systems offer enhanced relaxation but require specific care and maintenance, especially during winter months.

Understanding Your Massage Systems

Hydro Massage System:

  • How It Works: Powerful water pump drives water through jet nozzles
  • Targeted Massage: Typically 6 adjustable jet nozzles for focused hydrotherapy
  • Water Circulation: Draws water from tub, pressurizes it, returns through jets
  • Adjustable: Jets can usually be aimed and flow adjusted

Air Massage System:

  • How It Works: Special air pump blows air currents into water
  • Gentle Bubbles: Typically 15-16 ventilation openings create soothing bubbles
  • Full-Body: Provides overall gentle massage sensation
  • Relaxing Effect: Creates spa-like bubbling experience

Safety Warning: Never put fingers or other body parts into jet nozzles. Powerful suction can cause injury. If caught, immediately shut off pump.

Regular Cleaning & Maintenance

Keep your massage systems functioning optimally:

After Each Use:

  1. Rinse System: Run pumps for 30-60 seconds with clean water to flush contaminants
  2. Drain Completely: Open drain valve and let all water exit
  3. Run Pumps Briefly: With drain open, run pumps 5-10 seconds to expel water from lines
  4. Leave Drain Open: Keep drain valve open so any residual water can escape

Deep Cleaning (Monthly or as needed):

  • Flush with Cleaning Solution: Use spa line cleaner per product instructions
  • Scrub Interior: Clean hot tub with mild detergent and soft cloth
  • Inspect Jets: Check each jet for debris or blockages
  • Check Fittings: Ensure all connections are tight and leak-free

Cleaning Products: Use only mild, non-abrasive cleaners. Never use scratchy sponges or harsh chemicals that can damage surfaces and seals.

Winter Care (CRITICAL)

Freezing temperatures pose serious risk to massage systems. All hoses and nozzles must be protected:

Frost Warning: If pumps malfunction in cold weather and hot tub contains water, hoses will fill with water. Frozen water will crack hoses, damage pumps, and destroy fittings!

Prevention During Use in Cold Weather:

  • Run Pumps Frequently: Start pumps at least every 15-30 minutes to keep water moving
  • Maintain Temperature: Keep water temperature above 10-15°C at all times
  • Insulate Pipes: Wrap exposed pipes with pipe insulation
  • Thermal Cover: Keep cover on when not actively bathing

Complete Winterization Procedure:

When draining hot tub in freezing conditions, water MUST be removed from all system components:

  1. Drain Hot Tub: Open drain valve and allow water to flow out completely
  2. First Pump Run: Start hydro/air massage pumps for 5 seconds to expel water from lines
  3. Wait 2 Minutes: Allow any remaining water to drain to low points
  4. Second Pump Run: Run pumps again for 5 seconds
  5. Wait Again: Wait another 2 minutes
  6. Third Pump Run: Final 5-second pump run to ensure complete drainage
  7. Verify Drainage: Check that no water remains in visible hoses

Critical: Three-Time Rule! Running the pumps three times with wait periods between is essential. Single pump run will NOT remove all water. Frozen water will cause expensive damage!

Additional Winter Protection:

  • Open All Valves: Leave all ball valves half-open so any water entering can drain automatically
  • Remove Drain Plugs: Take out any removable drain plugs from pumps and equipment
  • Store Drain Plugs: Keep them safe for reinstallation in spring
  • Blow Out Lines (Advanced): If possible, use shop vacuum or air compressor to blow remaining water from lines

Using Massage Features

For optimal experience and equipment protection:

Hydro Massage Operation:

  • Water Level: Intake port must be covered with water before activating pump
  • Never Run Dry: Running pump without water causes immediate damage
  • Adjust Jets: Rotate jet faces to aim streams for personalized massage
  • Session Length: Limit intensive jet massage to 15-20 minutes

Air Massage Operation:

  • Water Level: Ensure ventilation openings are submerged
  • Gentle on Skin: Air bubbles are gentle; can run throughout bathing session
  • Temperature Drop: Air massage cools water faster; may need to add heat

Combination Use: Many users enjoy running both hydro and air massage simultaneously for ultimate relaxation experience. Ensure adequate water level for both systems.
