MANUFACTURER’S WARNINGS
In addition to the Safety Instructions found in this manual, these warnings have been assembled to help
you enjoy the use of your Softub. Reading and understanding these warnings will allow you to reduce
the risk of causing inadvertent damage to your Softub, your surroundings or yourself. Read these
warnings carefully.
•The water level must be 5 cm (2 inches) above the highest jet. The jets can spray water out of the tub
if the water level becomes too low and cause the HydroMate®to overheat and void the warranty.
•Always unplug your HydroMate®before draining and while filling.
•Use only approved accessories. Use of non-approved accessories could void the warranty.
•Maintain proper water pH (minimum of 7.2), the vinyl liner can be damaged by a combination of high
sanitizer and low pH.
•NEVER use an extension cord to connect the HydroMate®to the power supply cord. Using an
extension cord will void your warranty.
•Do not operate without a GFCI located on the power supply cord. This safety device shuts off the
power immediately in the event of an electrical short.
•Install the Softub only on floors or areas that can withstand repeated exposure to water (tile, brick).
Splashing, dripping, filling and draining are routine operations, which spill water. Equipment failure may
also cause substantial water spillage. Care must be taken that the structure underneath the Softub will
not warp or suffer damage in the event of a water spill. If located in a multiple floor structure, objects on
the floor below should be protected in the event of a major spill.
•NEVER use sharp objects in or around the Softub. Sharp objects may puncture the vinyl.
•Handle the HydroMate®gently. The components inside may incur damage if dropped.
•Certain objects reflect and concentrate the sun’ s rays. Close proximity of the Softub to such objects
should be avoided or damage may incur.
•Do not open the HydroMate®. There are no user serviceable parts inside. Opening this component will
void the warranty.
•Pets should be kept away from the Softub to avoid damage.
•A Softub Exterior Tub Cover is highly recommended if installing your Softub outdoors. Failure to do
so may cause premature permanent damage to the vinyl and other components and void warranty to
those components.
•Do not install the Softub where infestation of insects or rodents may occur.
•Children should not use the Softub without adult supervision.

INSTALLATION INSTRUCTIONS
SITE SELECTION
Before selecting a site, please read the safety information, manufacturer’s warnings and the relevant
indoor/outdoor sections. Your Softub is completely self-contained and portable. It can be set-up on a patio,
deck or even indoors.
A. Structure: the Softub should always be placed on a structurally strong, relatively smooth and level
surface. HydroMate®must never be pointing down towards tub. HydroMate®must be level when
connecting to tub or pointing up towards tub connections to get proper temperature readings. If
Hyrdromate®is pointing down towards tub, temperature readings can be inaccurate.
ACCEPTABLE
ACCEPTABLE
NOT ACCEPTABLE
B. Drainage: do not place the HydroMate®in an area where water will puddle around it.
C. Electrical: allow easy access to the ground fault circuit interrupter (GFCI) which is located on the power
supply cord. The 110 Volt GFCI and the outlet it is plugged into, should be protected from extreme
weather, landscape sprinklers and accidental spills.
D. Plug the HydroMate®into a 110 Volt outlet without the use of an extension cord. Be sure to use a
grounded electrical outlet that fits properly to the plug. The Softub cord has a special plug (called a
ground fault interrupter or GFCI) that is a very important safety feature. The GFCI shuts off electricity
to the HydroMate®immediately if there is a short in the cord or HydroMate®. It is designed to be tested
before each use. Be sure to push the GFCI “RESET” button to activate the power after plugging the
GFCI into the electrical outlet. This plug fits all conventional 110 Volt outlets found in homes.
E. A ground connector is provided under the motor unit to permit connection of a minimum No. 6 AWG
(4.1 mm) solid copper conductor between this point and any metal equipment, metal enclosures or
electrical equipment, metal water pipe or conduit within 1.5 m (5 ft) of the unit.
OUTDOOR INSTALLATION
You may place the Softub on any smooth surface (tile, concrete, wood, brick). Verify there are no sharp
objects under the tub prior to set-up. Placing the Softub on grass or other vegetation may damage the Softub.
If you need to step on grass or dirt to get to the Softub, we recommend the use of stepping stones to reduce
the amount of dirt and debris entering the tub. Check your local codes for restrictions (i.e. childproof gates).
VERY IMPORTANT! We recommend setting your Softub on a wooden deck or deck patio tiles that will allow
proper airflow underneath the tub to prevent water from being trapped under the Softub and causing mildew
etc. For easier maintenance, improved energy efficiency, better cleanliness and to prolong the life of your
Softub, always use the specially made Exterior Weather Cover available from your dealer.

pg. 7
NOTE: A Softub Exterior Tub Cover is highly recommended if installing your Softub outdoors. See
Maintenance (pg19) –Solar Exposure.
INDOOR INSTALLATION
Water splashing on the floor during use may cause a walking hazard and/or structural damage unless good
drainage is provided. Proper building materials must be used in the area surrounding and beneath the tub.
Take into consideration the room humidity, which will exist due to higher water temperature. Providing natural
or forced ventilation in the room will help maintain comfort and minimize moisture damage to the surrounding
environment. Consult an architect for aid in designing your indoor Softub room.
SET-UP CHECKLIST
________ 1. All Softub models come with locking straps. Be sure to place the safety straps in a “+”
fashion under the tub prior to filling, to match up with locks on bifold lid.
________ 2. Set the HydroMate®beside the Softub on the same level surface. Align the hoses from
the HydroMate®with the fittings on the tub.
________ 3. Place the clamps over the hose so that the drive nut is on the top of the hose, the head
facing the direction most easily accessible to tighten.
________ 4. Push the HydroMate®towards the tub while guiding the hoses over the tub
fittings. Push together until the end of the hose is flush with the back end of the black
fitting on the tub. Then connect the airline (smaller) hose.
________ 5. Slide the hose clamps towards the tub. The hose clamp should be 2 cm (3/4 inch) from the end
of the hose. Tighten the hose clamps with a nut driver or straight slot screwdriver.
________ 6. Connect light wires if Softub is equipped with LED lighting.
________ 7. With tub and HydroMate®connected, make sure placement allows easy access to all
components BEFORE beginning to fill tub. Adjust tub and HydroMate®placement, if
necessary.
________ 8. DO NOT PLUG IN THE HYDROMATE®until the tub has been completely filled.
________ 9. Before adding water, smooth out all wrinkles from bottom of tub by pushing liner to tub
wall. Softub 300: line up top seam of seat liner as close as possible to the edge of the
seat.
________ 10. Add 5 cm (2 inches) of warm water (not over 38°C - 100.4°F) and work out remaining wrinkles on
the bottom then continue filling.
Softub 300: Push wrinkles out in front and top of seat. Hold liner in corners of the seat
until water has completely covered the seat.
________ 11. Fill remainder of Softub until water is 5 cm (2 inches) above the highest jet.

pg. 8
________ 12. Check for leaks at the hose connections as the Softub is filling. If a leak is observed, stop
filling, make sure the hoses are properly sealed and the hose clamps are tight.
________ 13. Plug the HydroMate®into a standard, grounded, three prong, 110 Volt outlet.
________ 14. Place the foam hose insulation between the tub and the HydroMate®. Attach the vinyl cover
around the foam and fasten with the velcro tabs.
________ 15. Treat and test the water in accordance with the Water Treatment Guide.
________ 16. The Softub is now ready to heat to the desired temperature. Replace the bi-fold lid, close the air
control and adjust the temperature to the desired setting. The water temperature will rise at
about 1°F to 2°F per hour, depending on the model. The Softub will run until the water reaches
the set temperature. You should then fine-tune the dial setting, with the ꓥor ꓦbutton, until the
preferred temperature is reached.
It is the responsibility of the tub owner to make sure the above installation conditions are met as well
as to follow the safety and warning instructions. Softub Canada is not responsible for any damage,
which may result from water spillage, excessive humidity or structural loading. Please take all
precautions necessary to ensure years of joyful use of your Softub.

OPERATION
Temperature Setting
Push ꓥor ꓦbutton to set temperature, pushing ꓥor ꓦwill adjust the temperature to the setting you desire.
After selecting the desired temperature, the LED display will revert back to actual water temperature after 5
seconds.
Whenever the HydroMate®is running and has been running for at least 2 minutes, the actual water
temperature will be displayed in the LED display. If the HydroMate®is not running the display will show “P” to
indicate that the actual water temperature cannot be calculated at this time. In order to display the actual
temperature when “P” is displayed, press the “JETS” button and wait approximately 30 seconds for the actual
water temperature to display.
Jets Operation
When the tub water is at the set temperature, the jets will not be on. If you wish to use the tub with the jets
feature, pressing the “JETS” button on the control panel activates a 20 minute timer. This turns the jets on for a
20-minute period; to stop within that 20-minute period, press the “JETS” button again.
NOTE: If after 20 minutes the water temperature has dropped below the set temperature, the pump will switch
to HEAT mode and continue running to bring the water temperature up to desired temperature.
Filtration
The tub automatically runs if it determines that it requires filtration. When the tub is running in the filtration
cycle, the filter icon will glow. The digital controls are set to run two 15 minute filtration cycles in a 24 hour
period. These will run every 12 hours and are set when the hot tub is first plugged in. The filtration cycle will
only run if there has been no heat call in the prior 12 hours. If there has been a heat call, the filtration cycle will
be skipped.
Ground Fault Circuit Interrupter (GFCI)
The Softub cord is fitted with a ground fault circuit interrupter (GFCI), a very important safety feature. The
GFCI shuts off the electricity immediately if there is a short in the cord or HydroMate®. This plug fits
conventional 110 Volt outlets found in homes. It is recommended that the GFCI be tested upon each water
change.
The test procedures are as follows:
1. Push the “TEST” button on the GFCI and the light on the GFCI should go off. If the light fails to go out,
DO NOT USE YOUR SOFTUB. CALL YOUR DEALER OR SERVICE CENTRE FOR INSTRUCTIONS.
2. If the GFCI tests okay, firmly push the “RESET” button and the HydroMate®should resume power. If
“RESET” button fails to reset properly or if power does not return to the HydroMate®, DO NOT USE
YOUR SOFTUB. CALL YOUR DEALER OR SERVICE CENTRE FOR INSTRUCTIONS.
3. If the GFCI trips by itself at any time, firmly press the “RESET” button and perform the above tests. If
this happens more than once, DO NOT USE YOUR SOFTUB. CALL YOUR DEALER OR SERVICE
CENTRE FOR INSTRUCTIONS.

pg. 10
Ozone (if equipped with optional ozone)
Ozone is a gas that is used as an aid to the sanitizer in the water. Ozone helps to oxidize any contaminants in
the water. The tub automatically cycles ozone into the water for 1 hour of every 2nd heat call as well as during
a filtration cycle, should one be deemed necessary. The ozone is controlled by a solenoid that automatically
opens and closes an air pathway to the body of water. In the event of a manual activation (depression of the
jets button) the ozone is automatically turned off and will not run until the next heat call or filtration cycle. This
prevents the immediate contact with ozone as well as delaying the automatic opening of the air control, which
leaves the control of the air to the discretion of the user.
Air Control
The main air control valve (grey knob w\ handle) is located in the center of the control panel of the
HydroMate®. To open the air control, rotate the knob counter-clockwise one quarter of a turn. To close the air
control, rotate the knob clockwise. Each jet can be individually directed by rotating the head of the jet. After
using your Softub the air control should be turned off to prevent cooler outside air from entering the water and
prolonging the heat up time.
Multi-Color LED Underwater Lighting
Some Softubs come equipped with the multi-color LED lighting. This optional light offers several different
lighting effects for your tub.
The unit operates in the following manner:
Depressing the LIGHT button turns the light on in the same mode it was last in. For example: if the light was
white when it was shut off, it will be white when it is next turned on.
If the light is turned off then back on within 10 seconds, it advances to the next mode. For example: if the light
is white, is turned off and the back on within 10 seconds it will come back on in a different colour. Turning it off
and back on again within 10 seconds will now advance the mode to the next colour, and so on.

pg. 11
OPERATION MODES
Standard Mode
This mode is the default operating mode when first plugged in. The on & off cycling is thermostatically
controlled automatically by the HydroMate® unit’s SMARTCHIP . As the water temperature naturally cools
2-3 degrees the temperature sensor will activate the HydroMate® pump to reheat the water to the desired
temperature.
Overnight Mode When this mode is selected the unit will not operate for a heat call or filter cycle during the
twelve hours following mode activation. This will repeat daily. When in this mode the unit will operate normally
for 12 hours and standby for 12 hours. The unit must be up to the desired temperature on the LED display
(ex:104°F) before initializing this setting.
To enter this mode, Press and hold the Light button, Jets button & the ꓥbutton
together for 10 seconds, 12 will display on the control panel for 5 seconds to let you
know that you have entered this mode. The heat and filter LED’s will flash twice every
15 seconds to alert you that this mode is activated. The unit will not cycle on for twelve
hours after entering this mode. The following 12 hours the unit will cycle when needed
to filter/heat the water.
Economy Mode When this mode is activated the HydroMate®will turn on once per day to filter and heat the
tub to the desired temperature. This operation will repeat daily at the same time. This will take place at the time
of day that this mode was 1st initialized. The unit must be up to the desired temperature on the LED display
(ex:104°F) before initializing this setting.
To enter this mode, Press and hold the LIGHT button and the ꓥbutton together for
10 seconds, 24 will display on the control panel for 5 seconds to let you know that
you have entered this mode. The filter LED light will flash once every 10 seconds to
alert you that this mode is activated. When this mode is selected the unit will cycle
once per day to filter/heat water. This cycle will occur at the same time each day this
mode was activated.
NOTE: All modes can be reset/stopped if the HydroMate®is unplugged for 15 seconds. After a power
reset, optional mode will need be re-programmed.
Display Codes
•IPS –Insufficient Power Supply - The supplied power is insufficient and the HydroMate®has turned
off to protect the internal electronic components.
•P –Purge - A “P” will be displayed when the pump is not on, to indicate that the water near the
temperature sensors must be purged to get an accurate reading of the water temperature.
•P01 - This code indicates temperature sensor has not seen a change in temperature while the pump is
running of 1 degree over a period of 4 hours.
Note: Unplugging the HydroMate®for 10 seconds will reset\remove the error code and unit should run
as desired. Any special settings will need to be re-programmed.

SOFTUB MAINTENANCE
WATER TREATMENT SAFETY WARNINGS
•Read product labels carefully prior to use.
•Always test water before adding water treatment products.
•When diluting, always add water treatment products to water - do not add water to water
treatment products. Dry water treatment products should be dissolved prior to adding them in
the Softub.
•Always store water treatment products according to the direction on the label. All water
treatment products should be stored in a cool, dry and well-ventilated area where the average
daily temperature does not exceed 32°C (89.6°F). Keep storage area clean of debris such as
rags, newspapers and combustible materials.
•Always have the water circulating and air control turned off in the Softub when adding water
treatment products. Add water treatment products to the hot tub water one at a time. Allow
several minutes between any new water treatment product additions using the jets to evenly
distribute throughout the hot tub.
•Wait approximately 30 minutes after adding water treatment products to the hot tub before
closing up your bi-fold cover.
•Floating dispensers should never be used. They can bleach the liner and underside of the cover
by over-concentration and lowering the pH.
•Do not use gas chlorination, ionizers, scents, salts or soaps that are not approved for use in the
Softub hot tub. Consult your dealer for more information.
•There is a distinction between warm water and hot –the maximum safe temperature is 40°C
(104°F). Fifteen minutes per soak is the recommended time at 40°C (104°F).
•Never use a spa or hot tub if under the influence of alcohol or drugs.
•Do not add water treatment products while the hot tub is in use.

Water Treatment Overview
Proper water treatment is of utmost importance for maximum enjoyment and prolonged life of your
Softub hot tub. Proper water maintenance is essential for the health of your friends and family as well as for
permitting years of trouble-free use of your Softub hot tub. This informationis providedtohelpensure your comfort
andsafetyasyouenjoyyour Softub.Inaddition to important information about water treatment products and hot tub
maintenance, we have featured details on the use of recommended water treatment products. Our goal is to help
you get the most out of your Softub - to enjoy the fun, therapy and convenience.
Water balance is important to the overall performance of your hot tub. No hot tub’s water conditions are exactly
alike. The water source, location of the hot tub and frequency of use all effect the water balance. Unbalanced
water can damage the equipment, make the water uncomfortable for the user, and decrease the effectiveness
of the disinfectant. Total alkalinity, pH and calcium hardness must be within the correct ranges to achieve
balanced water.
As an introduction to water treatment, let us point out that a hot tub is not the same as a swimming pool. Although
some people think of hot tubs as miniature swimming pools the care of a hot tub differs from that of a swimming
pool in several ways. Unlike a swimming pool where water chemical balance usually changes gradually, changes
in chemical balance can happen almost instantly in ahot tub. Below are three factorsthat help demonstrate why
water treatment is quite different for pools and hot tubs.
•Consider the ratios of people per litres (gallons) of water. A hot tub may be about 1/50 the size of a pool.
Four people in a 1,800 litre (400 gallon) hot tub is about the same as 200 people in a typical 90,000
litre (20,000 gallon) backyard swimming pool.
•Because average water temperature in a hot tubranges between 37°C(98.6°F) and 40°C (104°F), each
person in the hot tub can perspire approximately 0.47 litres (1 pint) every 20 minutes. This elevated level of
perspiration increases the demand for sanitation.
•Becausehottubwateris aerated withhydrojets,thewaterturnoverrate isveryrapid.Thisincreasedwater
activitycan cause sanitizers to dissipate quickly.
The most common water treatment problems that can damage the Softub hot tub are:
1. Improper pH management - Too low a pH level will result in excessive wrinkles, damage to the vinyl
liner and corrosion in the motor unit.
2. Not removing the lid and pump not running when adding water treatment products - Leave the lid
off and the water circulating for at least 30 minutes after adding chemicals.
3. Use of improper chemicals - Sodium dichlor is the recommend type of sanitizer. Sodium dichlor
dissolves easily and has a neutral pH, which minimizes the effect that the addition of a sanitizer has on
pH balance. Trichlor compounds are not recommended because they have a very low pH, are very
strong and difficult to dissolve. Granules of this chemical may cause damage to the vinyl. High chlorine
or bromine levels can damage the vinyl and pose health risks. Floating dispensers are not
recommended because of the potential of high chemical concentrations. Use of Trichlor and floating
dispensers will void the warranty on your liner.

pg. 14
4. Over- Sanitizing –Over use of chlorine/bromine can potentially cause the liner to shrink and harden.
Not over sanitizing is key for liner longevity.
5. Not maintaining the water chemistry - The water chemistry in your tub should be checked at least
twice a week. If it is neglected and the chemistry is allowed to get out of balance, damage can be done
to your liner. It is the responsibility of the owner to properly maintain the chemical balance and
sanitation of the water. Softub is not responsible for any damages which result from improperly
maintained water. Improper water maintenance may result in voiding the warranty. If you have any
questions regarding water treatment, please contact your dealer.
Summary
When properly maintained, your Softub hot tub will last many years. The primary cause of failure is improper
care of the water. A regular program of water maintenance is essential. Please consult with your Softub dealer
if you have any questions.
•Recommended Water Balance
oFree Available Chlorine Residual : 2 - 4 ppm
opH 7.2 –7.8 ppm (ideal 7.6)
oTotal Alkalinity 80 –120 ppm
oCalcium Hardness 250 - 500 ppm
Test your water chemistry after each use of the Softub hot tub, but no less than twice per week. Avoid a low
pH, as this will cause unsightly wrinkles to form in the liner and could void your warranty.
•Chemical Additions
Empty your Softub hot tub and refill it with clean water 3-4 times per year or when it becomes cloudy and
difficult to balance the chemistry of the water. When in doubt, dump it out.

Water Treatment Guide
Water Balance –pH, Alkalinity & Calcium Hardness
Water balance is important to the overall performance of your hot tub. No hot tub’s water conditions are exactly
alike. The water source, location of the hot tub and frequency of use all effect the water balance. Unbalanced
water can damage the equipment, make the water uncomfortable for the user, and decrease the effectiveness
of the disinfectant. Total alkalinity, pH and calcium hardness must be within the correct ranges to balance the
water.
opH: Simply, pH is a scale indicating whether hot tub water is basic, neutral or acidic. Hot tub
water should be slightly basic with a reading of 7.2-7.8
Too low a pH (below 7.2) leads to corrosion of hot tub equipment and will irritate the skin of the
bathers. Also, the sanitizer will dissipate more rapidly.
▪A low pH can be corrected by adding pH Increaser.
Too high a pH (above 7.8) promotes scaling on heat exchanger tubes, creates cloudy water,
calcium deposits and reduces the effectiveness of disinfecting agents.
▪A high pH can be corrected by adding pH Reducer.
oAlkalinity: Total alkalinity is a measure of the alkalines in the water. They act as pH buffer
(stabilizer) preventing large changes in the pH. The total alkalinity should be between 80-120
ppm.
A low total alkalinity causes: the pH to wander; corrosive water; disinfectants to be ineffective
▪To raise the total alkalinity, add Alka-Rise.
▪A high total alkalinity causes: cloudy water; scale formation.
▪To lower the total alkalinity, add pH Reducer.
oCalcium Hardness: Calcium hardness is the hardness present due to dissolved calcium. The
desired range is 250 - 500 ppm
A low calcium hardness causes: corrosive water; staining of surfaces
To raise calcium hardness, add Cal Rise.
A high calcium hardness causes: scaling of heating pipes; cloudy water; staining hot tub
▪To correct this problem add Prevent II. Do not fill the hot tub with soft water!
Initial Start-up
Before adding chemicals, know your hot tub water capacity in litres or gallons.
YOUR HOT TUB CONTAINS
Softub 300 (6 person) 1137 liters
Softub 220 (4 person) 833 liters
Softub 140 (2 person) 530 liters
Scale can accumulate on hot tub surfaces and inside filters and heaters, greatly reducing their effectiveness.
Protect your hot tub equipment from scale caused by calcium deposits.

pg. 16
•Fill your hot tub with water and add Prevent II to hot tub water during filling. This establishes initial
protection against staining and scaling.
Test the hot tub water and balance it as needed. Always adjust Total Alkalinity first, then pH.
•Total Alkalinity (ppm) 80 - 120
•pH 7.2 –7.8
At this point the hot tub owner must decide which sanitizer system to use
Chlorine & Bromine Systems
Once your Alkalinity and pH are at proper levels and to establish an initial sanitizer reading, add Chlorinating
or Brominating Granules at a rate of 15 g (1 tablespoon) per 1,000 L (250 gals) of hot tub water. Sprinkle the
granules directly into the hot tub water with the pump running and air control open. Repeat additions every 15 -
20 minutes until a consistent Free Available Chlorine (FAC) residual of 3.0 - 5.0 ppm is established. Use test
strips or a reliable test kit to check sanitizer levels often.
MAINTENANCE SCHEDULE
Daily
1. Circulate the water for at least 2 hours to remove suspended particles that may exist.
2. Test for total alkalinity. Maintain the desired range of 80 –120 ppm
3. Test pH to maintain a level of 7.2 –7.8 ppm
4. Proceed with your appropriate disinfectant system…
Weekly
1. Test water and adjust total alkalinity and pH to be within ideal ranges.
2. Add sanitizer if necessary
3. Clean debris from suction intakes to avoid a decrease in water flow.
4. Shock water with 2 tablespoons of sanitizer or Spa Shock, leave lid off for at least 30 minutes.
Monthly
1. Clean filter with filter cleaner as per directions.
Chlorine System:
After water is balanced add 1 tablespoon per 250
gallons (1000 litres) as necessary to maintain
level of 3 –5 ppm This will establish an
immediate chlorine residual for disinfecting.
Bromine System:
A. After water is balanced add 1 tablespoon
per 250 gallons (1000 litres) as necessary
to maintain level of 4 –6 ppm This will
establish an immediate Bromine residual
for disinfection.

WATER TREATMENT TIPS:
•Always leave your bi-fold cover off or in half open position for at least 30 minutes when adding
water treatment products.
•Always read product labels before use.
•Use regular doses of sanitizer such as 1 teaspoon/person upon exiting.
•Use 2 tablespoons of preferred sanitizer when shocking the water, once or twice a week
depending on usage.
•Maintain an adequate sanitizer level at all times to kill bacteria, keep water clean and bathers
safe.
•Do not over sanitize. It can void your warranty.
QUALITY WATER TREATMENT PRODUCTS
We offer a complete line of quality products to support all of our water treatment options. Softub Canada offers
Sanitizers, Oxidizers, Balancers and Accessories, all formulated for maximum performance and value. Our line
of water treatment products provide numerous benefits. When used as recommended, they will:
•Make the water clean, safe and feel comfortable.
•Kill bacteria, which can multiply rapidly in a hot tub.
•Protect hot tub surfaces from stains caused by metals that are often dissolved in water.
•Protect hot tub equipment from scale caused by calcium deposits. Scale can accumulate on hot tub
surfaces and inside filters and heaters, greatly reducing their effectiveness.
•Maintain an adequate sanitizer level at all times to kill bacteria.
FILTRATION
A filter that is operating properly helps keep the water clean & clear by capturing hair, oils, and cosmetics that
wash off when people use the hot tub. When the filter is dirty or clogged, all this debris remains in the water.
Check your owner's manual for detailed information on how to remove the filter for cleaning. Typically, you
should clean your filter with an approved filter cleaner every 4 - 6 weeks.
We recommend Filter Cleaner (Part # 1720).
Use Spa Clear (Part # 1730) weekly. Some particles of debris are microscopic and too small for the filter to
capture. Spa Clear coagulates (groups) these tiny particles together, allowing the filter to collect them, and keep
the water clear.
TUB CLEANING
If left unchecked, contaminants such as dirt, oil, and even bacteria can accumulate at the waterline, much like a
bathtub ring. Regular cleaning preserves the Softub surfaces so the whole hot tub environment looks and feels
clean and fresh. Use a skimmer net to remove floating debris.

Emptying & Refilling
NOTE: Many hot tub and hot tub manufacturers recommend the use of a Hot Tub Plumbing Cleaner such as
Whirlpool Rinse (Part # 1705) prior to draining.
If Whirlpool Rinse is used, follow this procedure:
1. Remove filter cartridge.
2. Pour 250 ml of Whirlpool Rinse into hot tub or hot tub prior to draining.
3. Turn pump on and run for one (1) hour with air control in CLOSED position.
5. Drain Hot tub.
6. Repeat each time the hot tub is to be emptied and cleaned.
If Whirlpool Rinse is not used to clean the plumbing system between fillings:
1. Drain the water.
2. Clean the hot tub surfaces.
3. Refill the hot tub with fresh water.
4. Add the recommended Softub products.

Inner Liner Care
While empty, use a mild soap solution to wipe any soil or stains on the inner liner. Rinse thoroughly before
refilling the tub. Do not use cleaning aids such as steel wool. Stiff bristle brushes, abrasive cleaners, acidic
cleaners (such a citrus based cleaners) or cleaners containing harsh chemicals including bleach and ammonia.
If your liner does get a tear or puncture, contact your dealer.
Exterior Vinyl Care
The exterior of the tub, lid HydroMate®and vinyl cover are made of marine grade vinyl specifically formulated
to resist UV, mildew, cracking and discoloration.
•Cleaning
Use a mild soap and water solution to wash the vinyl, then rinse with clean water. Avoid abrasive soaps,
tools or any other solvents. Improper use of these products can void the warranty.
Use of vinyl protectants, such as those commonly found in auto parts stores can accelerate the aging of
your tub, causing cracks in the vinyl that are not covered under warranty.
•Solar Exposure
If your Softub is located outside, we strongly recommend the use of the Softub Exterior Tub Cover
(available from your dealer). This will protect the Softub from excessive direct ultra-violet (UV) exposure,
keep rain water out of the tub and keep the exterior surface clean. Never cover your Softub with a
transparent plastic covering of any sort as it may will cause irreparable damage to your Softub.
•Repair
If your exterior does get a tear or puncture, contact your dealer.
Filter Cleaning, Installation and Removal
•You must first soak the filter collar in warm water for one to two minutes for ease of installation.
Do not attempt to remove or install the filter unless the filter collar is warm. To remove, gently
push sideways away from the tub wall to release the filter from filter strainer cover. Clean your
filter at least once a month or more often depending on usage. To do so, remove the filter, remove the
outer sock and follow the filter cleaner packaging directions. Replace the sock and then gently snap the
filter into position on either of the suction strainer covers. The filter should be replaced at least once a
year.
Winterizing
If you are leaving your tub for an extended period of time, or do not plan on using it, drain your system
completely. Turn the HydroMate®so that the hoses are facing down and allow all water to drain from the
internal plumbing. Failure to do so may cause the water to freeze in cold climates and severely damage your
unit. Ideally stored in a warm area and horizontally, never on its side.
