SAVE THESE INSTRUCTIONS
IMPORTANT SAVE THESE INSTRUCTIONS
Your physiological response to hot water is subjective and depends on your age, health, and medical history. If you don’t know your
tolerance to hot water, or if you get a headache, or become dizzy or nauseous when using your hot tub, get out
and cool off immediately.
WARNINGS
1 Children should NOT use a hot tub
without alert adult supervision.
2 Children should not enter a hot tub where water
temperature exceeds body temperature (37°
C / 98.6°F).
3 Prolonged immersion in water temperatures in
excess of 38°C (100°F) may be injurious to your
health. We recommend establishing lower temperatures and
shorter use periods for young children and/or those users potentially affected by hot temperatures. Always confirm water
temperature with an accurate thermometer before entering
your hot tub.
4 Do not allow children to submerge their head under water.
5 Do not use a hot tub unless all suction guards are installed to
prevent body and hair entrapment. Do not sit in front of, or on
top of the suction fittings or skimmer, as this will obstruct
proper circulation and may result in personal injury.
6 Never operate the hot tub pump at high speed without
having all suction and return lines open.
7 Always keep the hardcover installed and locked when the hot
tub is not in use.
8 People using medications and/or having any adverse
medical history should consult a physician before using a hot
tub.
9 People with infectious diseases should not use a hot tub.
10 Exercise caution when entering or exiting a hot tub.
Where practical, install a safety grab bar or handrail.
Turn off the jets before entering the hot tub to improve
visibility of the steps or flat entry area.
11 To avoid unconsciousness and possible drowning, do not
use drugs or alcohol before or during the use of a hot tub.
12 Pregnant women should consult a physician before using a
hot tub.
13 Do not use a hot tub immediately following strenuous
exercise.
14 Do not permit or use electric appliances (such as a light,
telephone, radio or television) within 1.5 m (5 ft) of this
hot tub, unless such appliances are rated at 12VDC or less.
15 Test the GFCI (Ground Fault Circuit Interrupter) monthly.
16 Post emergency phone numbers for Police, Fire Dept.,
and Ambulance at the nearest phone.
17 Maintain water chemistry/balance in accordance with
manufacturer’s instruction
HYPERTHERMIA
Since your hot tub can be set to reach temperatures of 40°C (104°
F), users should be aware that extended submersion in water that
exceeds normal body temperature can lead to hyperthermia.
The causes, symptoms and effects of hyperthermia may be described as follows:
Hyperthermia occurs when the internal temperature
of the body reaches several degrees above the normal
body temperature of 37°C (98.6°F). The symptoms of
hyperthermia include drowsiness, lethargy, and an increase in the
internal temperature of the body. The effects of hyperthermia include:
• Unawareness of impending hazard
• Failure to perceive heat
• Failure to recognize the need to exit the hot tub
• Physical inability to exit the hot tub
• Fetal damage in pregnant woman
• Unconsciousness resulting in the danger of drowning
If you sense any of the symptoms of hyperthermia, safely
exit the hot tub immediately.
WARNING
THE USE OF ALCOHOL, DRUGS OR
MEDICATION CAN SIGNIFICANTLY INCREASE THE
RISK OF FATAL HYPERTHERMIA.

CHOOSING THE RIGHT LOCATION
Your Hydropool hot tub can be installed indoors or out, on the ground, in the ground or half-and-half. The following
information will assist you in choosing the right location for your individual needs. When making your decision,
always remember that hot tubs can be enjoyed year-round, indoors or ou t, regard less o f the climate. Many Hydro-
pool owners report that their favourite time to use a hot tub is in the cooler fall and winter months, while others
praise the enjoyment of using their hot tub in the warmer spring and summer months.
INDOOR LOCATIONS
If members of your family are not cold weather enthusiasts, or if your backyard or patio area is not suitable for a
hot tub installation, then an indoor location for your hot tub
may be your best or only choice. You may wish to create
an exercise/spa area in your home, or install your hot tub
in a glass solarium or four-season room adjoining your
home. Indoor installations not only add a uni que look and
appeal
to your home, they provide the privacy and controlled climate to ensure that use and enjoyment of your hot tub is
maximized.
If you should choose an indoor location, you will find further
information as outlined in the section
“SPECIAL CONSIDERATIONS FOR INDOOR
INSTALLATIONS”
OUTDOOR LOCATIONS
For a variety of reasons, outdoor locations are a far more
popular choice. Some of the reasons include:
• Limited indoor space
• Delivery complications due to door openings, stairwells, etc.
• Limited budget (indoor installations usually also
involve interior home renovations)
• Desire for an outdoor entertainment center
• Hot tub is being installed adjacent to an existing or
planned swimming pool
• Concerns over splashing water inside the home
For those who choose an outdoor location, hot tub oper ating temperatures can be adjusted to match the season. In
colder months, many owners will operate their hot tub in
the range of 38-40°C (101 -104°F).
During warmer months, an operating temperature of 36-37°
C (97-99°F) will provide a refreshing retreat. If you should
choose an outdoor location, you will find further inform ation
as outlined in the section
“SPECIAL CONSIDERATIONS FOR OUTDOOR
INSTALLATIONS”

GENERAL INSTALLATION CONSIDERATIONS
1 Your HYDROPOOL Hot Tub is a self-contained pre-plumbed
unit, so that no on-site plumbing connections to the residential water supply or drain are required.
2 Ensure that your HYDROPOOL Hot Tub is properly sup-
ported by either a level concrete pad, or a properly constructed deck capable of supporting 1220 kg/m2 (250 lbs./
ft.2). If there is a possibility that the pad could shift by freezing/thawing ground movement (such as in clay regions, a nd/
or areas with high water tables) concrete footings extending
below the frost line are recommended.
3 Decking should be chosen and constructed in a manner t hat
minimizes the chance of slipping or falling.
4 Level your hot tub using wood shims where necessary, en-
suring that the tapered end extends at least 61 cm (24 in.)
under the unit.
5 If you do not have a factory installed insulated cabinet, it is
assumed that you are building your own custom cabinet,
tiling or decking.
Please consider the following:
a Your HYDROPOOL Hot Tub is self-supporting on its
base. The cabinet should be decorative only, not for support. Never suspend the hot tub from the deck or cabinet.
b Where the hot tub is not equipped with a factory installed
cabinet, it is the installer’s responsibility to ensure all
electrical equipment is weather protected.
c Always provide adequate access for servicing the
support equipment.
d Decking should be constructed to allow repair access
around the entire hot tub.
e In remote equipment or no-cabinet installations, you
may add extra insulation, but the equipment area
must have adequate cross-flow ventilation.
6 Installation of a safety grab rail or reachable support for use
when entering or exiting the hot tub is recommended.
7 A nearby garden hose connection is recommended for
filling and “topping up” the hot tub.
WARNING
The hot tub equipment and all electrical
plugs, outlets and lights within 1.5m (5ft) of
the hot tub must be G.F.C.I protected. Consult your electrician or local electrical authority for further details.
Access to the hot tub must always be secured:
Outdoors - in accordance with local property by-laws
and/or via an approved fence with a self-closing gate and
a safety hardcover;
Indoors - by a lockable door and a safety hardcover.
SPECIAL CONSIDERATIONS
INDOOR INSTALLATIONS
• When the hot tub is to be installed in a small room (under
150 ft2/14 m2), we recommend that large units be fully or partially submerged in-floor so that it does not dominate the room.
This will also provide greater overhead clearance for entry and
exit to and from the hot tub
• It is beneficial to have the hot tub room located near wash
room and shower facilities
• The hot tub room should have a floor drain to handle spl ash
water, a window, outside exhaust fan or humidistat controlled
exhaust fan for ventilation. Where this is not practical, the use
of indoor/outdoor carpeting or a tile floor and the opening of a
window while the hot tub cover is removed should be sufficient. You should not have concerns regarding humidity. When
the hardcover is installed, no humidity will escape. During use,
the small amount of humidity released into the room can be
removed with the use of a dehumidifier
• Consider plumbing a water tap and drain location nearby to
facilitate draining and top-up
• Always provide adequate ventilation for the support equipment
• Consult your local Hydropool retailer for further information
OUTDOOR INSTALLATIONS
• Contact your local building code department to determine if
a building permit is necessary and for information on applicable bylaws (distance from property lines, buildings, fencing requirements, etc.)
• If you are doing any excavating, contact your local gas,
electric, and cable-company to ensure that there are no underground lines
• Locate the hot tub, where practical, within close distance of
a door to the house to maximize potential winter use.
• Ensure that all hot tub support equipment is easily
accessible and protected from the elements
• If possible, locate the hot tub where you will enjoy some
privacy, out of the site of neighbours. If this is not possible, a
partial privacy or wind partition, or proper placement of the
optional Hydropool cover lifter should provide adequate privacy
• The hot tub support equipment is designed for indoor (out of
the direct elements) use. When your HYDROPOOL hot tub
is equipped with a factory-installed cabinet, and installed as
per the guidelines of this manual, the equipment will be adequately protected. If the hot tub is shipped without a cabinet,
your custom cabinet or other structure must be designed to
supply protection for the hot tub support equipment from
rain, snow, splash water, etc., but still designed in a manner
to ensure adequate ventilation.
6
SITE PREPARATION
ABOVE-GROUND INSTALLATIONS
Where the hot tub is a “stand-alone” above-ground installation
to be installed in regions where freeze/thaw conditions may
occur, a level patio stone or pre-formed paver type base may
be sufficient if there is no abutting deck(s) that could be damaged during potential seasonal movement of the ground. The
potential drawback to this type of base is that splash water
could eventually de-stabilize the ground under the base, with
the resultant shift of the support base causing damage to the
hot tub structure.
For best results, we recommend the installation of a level
concrete pad:
• Dig out and level the ground 20-30 cm (8-12 in.) below
your desired base level
• Install 10-15 cm (4-6 in.) of crushed stone
• Next, install 10-15 cm (4-6 in.) of poured concrete
• Level the concrete and apply a broom-type finish
• We recommend that the pad be made 15 cm (6 in.) larger
than the hot tub on three sides, and 1 m (3 ft.) larger on
the side where the access steps and/or planters will be
installed.
In regions where freeze/thaw occurs, or where there will be
custom decking abutting the hot tub we recommend the installation of sono-tubes beneath the pad to prevent shifting.
IN-GROUND & PARTIAL IN-GROUND
INSTALLATIONS
For units being installed fully or partially in the ground, the type
of support will again vary based on whether or not the tub is
being installed in an area with freeze/thaw conditions. Hydropool does not recommend back-filling full in-ground or partial
in-ground installations.
• Non-freezing climates – it is sufficient to ensure that the base
of the hole or cavity created for the tub has a dry, stable, compacted level base and proper drainage
• Climates where freeze/thaw occurs – it is necessary that a
poured level reinforced concrete base, complete with concrete
footings, be installed as outlined in the section
GROUND INSTALLATIONS
•Areas with a high ground water table – a level concrete base,
as well as a concrete or wood retaining wall to hold back the
earth, is recommended. This forms a box or ‘bunker’, in which
the hot tub is placed
• ALWAYS ensure that there is good drainage, via a properly
designed French drain (gravel) system and/or a sump pump, to
prevent ground water flooding damage to the support equipment or hot tub structure
• Install protective waterproof conduit to house light, or topside
control cables that will be buried
• Access for future service must be considered at the time of
design and installation. Difficult access can result in supplem ental service labor charges not covered by the factory warranty.
Consider easily removable deck materials.
• Make sure the hot tub or swim spa is tested during 48 hours
before you prepare the installation of the surrounding/finish
deck around your hot tub. Even though all units are tested in
our plant, some transport/site handling damage can occur and
we suggest you make sure the tub is perfectly waterproof before finalizing your installation.
ABOVE-
OVERALL SUPPORT
Your Hydropool hot tub is equipped with a factory installed load
support substructure, which distributes the weight of the water
over the entire foot area of the hot tub. The cabinet, either factory installed or customized on-site, should be decorative only,
and not relied on for overall support. Never suspend a hot tub
from a deck or floor by the outer acrylic edge, as this will lead to
product damage and/or serious personal injury.
LEVELING YOUR HYDROPOOL HOT TUB
After the hot tub is properly positioned on the support base,
the entire unit should be checked with a level and shimmed
as necessary. Should you find that the support base is sloped
or otherwise uneven, level your hot tub using TAPERED
wood shims where necessary, ensuring that the tapered end
extends at least 61 cm (24 in.) under the unit.
This will insure contact with the support substructure to appropriately distribute the weight of the unit. Do not just shim under
the cabinet base outside edge, as this will cause structural
stress on the unit, potentially causing unwarrantable damage to
the hot tub structure and /or shell.
7
EQUIPMENT ACCESSIBILITY AND PROTECTION
The equipment must be located in an area where it will remain
dry and will not be exposed to rain, snow or ground water. The
standard Hydropool hot tub has the equipment installed inside
the protective cedar cabinet.
• When your hot tub is to be installed above-ground, the cabi-
net is designed for both protection and accessibility
• When your hot tub is to be installed fully or parti ally in the
ground, if you are relocating the equipment remotely from the
hot tub, or if you have ordered a hot tub without
UNLOADING / HANDLING YOUR HOT TUB
All Hydropool hot tubs are shipped with a protective com bination layer of foam wrap, cardboard and plastic film. Each hot
tub is factory strapped onto a wood skid. If your hot tub is to be
delivered by your local dealer, it will generally arrive on a flat
bed truck or low profile trailer. Most dealers are equipped with
the necessary equipment to maneuver the hot tub from the
truck to the dolly or cart that will be used to move your hot tub
to the installation location.
Should your hot tub arrive in a common closed box trailer, it
may be necessary to arrange with a local towing company for
a tilt and load tow truck, with a pulley winch system, to pull the
skid from the larger trailer to the lower profile tow truck flat
bed. The hot tub can be gently slid off the low profile trailer and
positioned on its side on a cart or dolly on its back side only.
a cabinet: it is necessary that the equipment is installed in an
area that is dry, protected from the elements, has proper ventilation and is easily accessible for service
• Always ensure that the equipment is mounted on a raised
base or platform to prevent potential water damage to the motor, equipment or controls
• Ensure that access to the equipment and the working area
around the equipment is large enough to accommodate a service person
Most Hydropool models require a clearance width of at least
100 cm. (39 in.) to allow movement of the unit on its side
through alley-ways, fence openings, etc. Where this is not possible, the use of a crane to lift the hot tub from the truck or
trailer over the house to the patio or yard is often a simple and
economical option.
WARNING
• Do not move or place the hot tub on the side where the
equipment is located as damage could occur
• Never roll or flip the hot tub end over end as the cabinet
could be damaged
• Never lift or handle the hot tub by the
plumbing
• Make sure that there is sufficient assistance to gently slide the hot tub off the dolly
or cart to the support base without any damage
Important Note: Damage caused during transportation or by
improper handling is not covered by the factory warranty.

Hydropool offers several different devices to assist in the
removal of the safety hard cover. Please refer to the instructions supplied with your particular cover remover for
installation. For further information, contact your local Hydropool retailer.
YOUR DREAM SCENTS AROMATHERAPY SYSTEM
Operational Instructions:
This exclusive aromatherapy system is independent from
the blower and uses liquid scents.
To operate the system is very simple:
1) To fill begin by opening the cap “counterclockwise” on
the unit and remove. There are arrows on the cap to indicate the direction in which to turn the cap to open. Then
fill the reservoir with your favorite Hydropool liquid scent
(or equivalent).
To replace cap perform the reverse of the above directions.
2) Now the system is ready to work: just push the button
to release the scent into the hot tub and repeat to add
more liquid scent as desired, please note by turning the
button clockwise you can lock it so that any accidental
pushing of the button will not result in adding unwanted
liquid scent when not desired. To unlock turn button
counter-clockwise.
SAFETY HARDCOVER LOCKS
The ASTM approved safety hard cover is designed to
open away from the control area, however, if the hot tub is
symmetrical in dimension, the cover can be oriented to
open in either direction. Simply place the cover on the hot
tub, pull the straps down so that they are fully extended,
then release slightly so that there is approximately 6 mm
(1/4 in.) of slack. Mark the position on the cabinet, and
fasten the receiver clip with the screws provided.
CAUTION
Always ensure the safety hard cover is in
place and locked whenever the hot tub is
not being used.
12
GATE VALVE
FILLING, CHECKING AND STARTING YOUR HOT TUB
FILLING
• When adding water for the first time, the hot tub should be
filled through the skimmer opening (helps to prevent air
locks) using a standard garden hose, turning the tap on
slowly to prevent damage to the surface by a jerking hose
connection.
• Pull up the handles on the intake and return gate valves
(handles are pulled up when valves are open and pushed
down when valves are closed).
• Ensure the drain hose-bib is closed.
• Ensure that all jets are open. See section JET &
FEATURE OPERATION
UNIONS
PROPER WATER LEVEL AT
SKIMMER OPENING
• Fill the hot tub to the recommended level, approximately 4
inches above the top of the skimmer opening.
CHECKING
• Although your hot tub was thoroughly water-tested in the
factory, some loosening of fittings can occur during shipping. Before any decking, tiling or carpeting is completed
around the installation, fill and operate your hot tub to test
for leaks (this ensures easy access and inexpensive correction). Check all union connections and plumbing for
minor leaks. In the event of a leak, ensure all union connections and pump plugs are tight and all o-rings/gaskets
are in place.
STARTING
• Before applying voltage to power-up your hot tub, it is
very important that you understand the sequence of
events that occur when the system is activated in order
that the pump can be primed efficiently and damage to
the system can be avoided.
• Turn the main power “on” at your electrical panel.
• Follow the control instructions for your particular model
hot tub to put the pump into low speed see section HY-
DROPOOL CONTROL SYSTEMS PUMP PRIMING/
RELEASING AN AIR LOCK
• On some systems a message will appear on the display
indicating that the system is in PUMP PRIMING MODE
(“RUN PMPS PURG AIR”). This mode will last for 4 minutes before automatically entering the normal operation
mode. See complete details for your spa in section
HYDROPOOL CONTROL SYSTEMS
Definition: ‘Priming’ a pump is a term used to describe the
process in which air trapped in the plumbing and pump
wet-end (referred to as an ‘air lock’) is released, allowing
the pump to move water efficiently through the plumbing
system and to the jets.

RELEASING AN AIR LOCK...
HOSE BID
• When the hot tub pump is located below water level, the
water should start circulating immediately. If the motor
works but you do not notice water circulation within the first
15 seconds, the pump may require priming due to trapp ed
air (referred to as an ‘air lock’). If the pumps have not selfprimed after 2 minutes, and water is not flowing from the
jets, DO NOT allow the pumps to continue to run. Turn
power off at the main house panel (or GFCI) and try releasing the air by loosening the union on the discharge side of
the pump(s) while the motor is not running. Turn the power
back on. If the pumps do not prime after 15 seconds,
sometimes momentarily turning the pump(s) off and on will
help the system to prime (note: do not do this more than 5
times).
• Important: Under NO circumstances should the pump(s) be
allowed to operate without priming beyond 5 minutes, as
this may not only cause unwarrantable damage to the
pump, it may also cause the control system to go into an
overheat condition.
• Turn the pump onto high speed and re-check for leaks.
The control system will automatically return the pump to
low speed after 15 minutes.
• Adjust the hot tub heat control at the topside panel to the
desired water temperature.
• Adjust water balance (pH, TA, calcium hardness) to recommended levels and add sanitizer once the water temperature
reaches 20°C (68°F). See section HOT TUB WATER BAL-
ANCE
• The hot tub will require 8-10 hours to reach the desired
temperature.
• Keep insulated safety hard cover on the hot tub, and the
air controls closed during the entire heat up process.

HYDROPOOL SERENITY – ALL SERIES
INITIAL START-UP
Before applying voltage to power-up your hot tub, it is very
important that you understand the sequence of events that
occur when the system is activated in order that the pump
can be primed efficiently and damage to the system can be
avoided.
At initial power-up, this display will appear, and the system
will show 4 sets of numbers in succession as follows (M100,
_200, V4 and 240V). These numbers represent the current
software revision, and the system input voltage. After the
initial software indicators are shown, the display will flash
“LINK”. This refers to “linking” the TP600 control panel with
the system and is done by pressing any key on the control.
After this is done the display will show “RUN PMPS PURG
AIR”. This displa y is indicating that the system is in PUMP
PRIMING MODE. This mode will last for 4 minutes before
automatically exiting and entering the normal operation
mode. You can also manually exit PUMP PRIMING MODE
by pressing any TEMP button.
While in this mode, the heater circuit is disabled to allow the
priming process to be completed without the possibility of
energizing the heater element during low flow or no flow
conditions. The system will not automatically activate any of
the functions, however, by pushing the pad on the topside
control, the pump can be manually activated to facilitate
priming.
Definition: ‘Priming’ a pump is a term used to describe th e
process in which air trapped in the plumbing and pump wetend (referred to as an ‘air lock‘) is released, allowing the
pump to move water efficiently through the plumbing system
and to the jets.
PUMP PRIMING MODE
As soon as “RUN PMPS PURG AIR” is indicated on the
topside panel, push the pad to start Pump 1 in low speed,
then again to switch to high speed to facilitate priming. See
FILLING, CHECKING AND STARTING YOUR HOT TUB
for complete instructions on pump priming.
Once pump priming has been successfully completed, press
the pad to turn off the pump.
Next, manually exit PRIMING MODE by pressing any
“TEMP” button. If you do not manually exit PRIMING
MODE, it will automatically terminate after 4 minutes. Be
sure that the pump is primed before exiting this mode.
SET TIME
After the system exits PRIMING MODE, it will ask you to
“SET TIME”. See the instructions on the following pages.
TEMPERATURE CONTROL
FUNCTIONALITY
AND ADJUSTMEN T
After you manually exit or the system automatically exits
Priming Mode, your hot tub will automatically heat to the
factory preset default temperature of 38°C (100°F) The topside panel will briefly show the default temperature, and
then the display will appear as follows:
Note that the water temperature is not yet displayed, as the
system requires approximately 2 minutes of water flow
through the heater to determine temperature. This is referred to as ‘polling’ and is indicated on the display by the
icon. After 2 minutes the display will show the current measured water temperature
Press the pad to increase the temperature to the desired
setting. The Heat indicator light on the Topside Panel will
shimmer for 90 seconds, indicating that the system is not
yet heating, then will illuminate solidly to indicate that the
heater circuit has been energized and the spa water is being
heated.
In Standard Operating Mode, the system automatically activates Pump 1 low speed every 30 minutes for at least 2
minutes.
After 2 minutes, the spa water temperature is determined. At
this point, if the water temperature is lower than the set temperature, P1 will continue to run and the Heat indicator light
on the Topside Panel will illuminate. The heater will operate
until the water temperature reaches the set temperature
point, after which, both the heater and Pump 1 low will automatically turn off.
To Check/Change the Set Temperature
The last measured temperature is constantly displayed on
the topside panel. When this pad is pressed once any time
during normal operation, the display will sh ow the set temperature for 3 seconds. Press this pad a second time to
increase or decrease the set temperature. To change the
direction of the temperature settings (ie. lower vs. raise the
temperature), allow the display to revert back to the current
water temperature then press the pad again.

JET WATER FLOW ADJUSTMENT
Your Hydropool hot tub features adjustable water flow on
specific hydrotherapy jets. To reduce the flow: grasp the
outer flange of the jet, and turn clockwise approximatel y a
1/4 turn. When it hits the stop, the jet is considered closed,
and flow will be restricted. To increase the flow: from the
closed position, turn the jet counterclockwise approximately
1/4 turn. When it hits the stop, the jet is open, and there is
maximum jet flow. Do not attempt to turn the jet past the
stop, as this will unclip the jet internal from the socket.
All Hydropool hot tubs are shipped from the factory with the
jets in the open position.
JET AIR FLOW ADJUSTMENT
Your Hydropool hot tub features adjustable airflow on specific hydrotherapy jets. To reduce the flow: turn the handle
on the air control clockwise. When it hits the stop, the air is
closed, and airflow will be restricted. To increase the flo w:
turn the handle on the air control counter-clockwise. When it
hits the stop, the air control is fully opened. For maximum
operating efficiency, the air controls must remain closed
when your hot tub is not in use.

HOT TUB WATER BALANCE – GENERAL OVERVIEW
NOTABLE POINTS
• The reliability and longevity of your hot tub support equi pment
are directly related to how well water quality is maintained!
• The small volume of water in your hot tub is easily affected by
the introduction of oils, lotions, perspiration and chemicals. It is
imperative that you give your hot tub regular attention to maintain clean, safe and balanced water to prevent premature damage and/or failure (corrosion/calcification) to the support equipment. Maintaining proper hot tub water balance and sanitizer
levels is extremely important. Neglected hot water will allow
bacteria to quickly spread.
• The mineral content of hot tub water increases due to water
evaporation, sanitizers and other chemicals. If the mineral concentration, particularly calcium, becomes too high, the minerals
will literally “drop” or precipitate out of the water and deposit on
the hot tub walls, plumbing, jets, in the filter and on the heater
element.
• It is very important that pH be checked frequently and maintained in the recommended range as indicated in the chart WA-
TER BALANCE SUMMARY FOR YOUR HOT TUB
• It is also very important that Total Alkalinity (the ability of the
water to resist a change in pH) be maintained in the recommended range as indicated in the chart WATER BALANCE
SUMMARY FOR YOUR HOT TUB
• Although there may be two identical hot tub models right next
door to each other, the maintenance requirements will be different, dependant on such factors as:
– bather load
– frequency of use/quantity of bathers
– different body chemistry
– sun vs. shade
– temperature
For these reasons, it is very important to develop proper hot tub
water maintenance habits and follow your Hydropool retailer’s
recommended water maintenance procedures.
Heater and other component failure due to
improperly maintained pH or Total Alkalinity
is not covered under warranty.
WARNING
CHEMICAL HANDLING SAFETY HINTS
• Never pre-mix chemicals with each other
prior to adding to hot tub water.
• Add only one chemical to the water at a time.
• Always add chemicals to water and not vice-versa.
• Chemicals may be corrosive, so handle with care and
store in a cool dark place.
• Never smoke near chemicals as most are flammable
• Ensure any spilled chemicals are carefully cleaned up
immediately.
• Always have the POISON CONTROL telephone number
handy in the event of an emergency.
• Keep chemicals out of children‘s reach
• Wear safety glasses and gloves when handling chemicals.
INITIAL WATER FILL & BALANCE
1 Make sure the hot tub water is circulating and above 20°C
(68°F)
2 Add a sequesterant (stain and scale c ontroller). Allow water
to circulate for an hour before adding anything else to the hot
tub water.
3 Add a Shock / oxidizing agent .
4 Add sanitizing tablets (Bromine or Chlorine) to the dispenser:
Built in dispenser: if your Hydropool hot tub was ordered with
the optional built in bromine/chlorine dispenser, (located unde r
the basket of the cartridge filter housing), refer to section
CARTRIDGE FILTER for details on removing and reinstalling the lid. Once the filter lid is removed, you’ll notice a
clear 2.5 cm (1 in.) tube extending from the bottom of the basket. Expose the large Refill hole at the end of the tube and add
5 or 6 tablets. Do not overfill dispenser as performance will be
affected. Turn to expose the most number of smaller holes and
allow water to circulate for 3 to 4 hours
before testing level. Adjust to lesser number of holes as necessary to maintain a
level of 2-4 PPM Sanitizer.
Floating dispenser: As above, add 6 or 7
tablets, adjust initially to ‘5’, allow water to
circulate for 3 to 4 hours, then test. The
tablets will dissolve slowly over a 10-14
day period, depending on dial setting, and
use of the hot tub.
5) Test pH and Total Alkalinity and adjust
accordingly.
23
GLOSSARY OF COMMON WATER MAINTENANCE TERMS
1 CHLORINE – in granular, liquid or puck/tablet form, is an oxidant and biocidal agent. It is ver y effective and fast acting. Recom-
mended chlorine residual level is 3.0 to 5.0 ppm.
2 CHLORAMINES – a compound formed when chlorine combines with nitrogen or ammonia present in the water. When allowed to
go unchecked, it causes eye and skin irritation and is indicated by a strong chlorine odor.
3 ONE-PART BROMINE – also available in puck/tablet form, is another type of oxidant/biocidal agent, and is intro duc ed int o the ho t
tub water via a brominator. Recommended bromine residual level is 3.0 to 5.0 ppm
4 TWO-PART BROMINE – composed of a liquid or powder component introduced manually into the water on a weekly basis, and a
granular component that is added daily or as the hot tub is used.
5 BROMAMINES – are formed when bromine destroys nitrogen-bearing organic matter. Unlike chloramines, bromamines don’t
cause eye irritation, however, when allowed to go unchecked, will cause an objectionable odour.
6 SHOCK – the practice of adding an oxidizing agent to hot tub water to destroy ammonia, nitrogeno us and organic contaminants
(chloramines and bromamines)
7 pH – a logarithmic value expressing the relative acidity or basicity of a substance (such as hot tub water) as indicated by the hydro-
gen ion concentration. pH is expressed as a number on a scale of 0 to 14, where 0 is most acidic, 1 to 7 bein g acidic, 7 consid ered
neutral, 7 to 14 being basic, and 14 being most basic. The ideal range for hot tub water is 7.4 to 7.6 ppm
8 pH INCREASER – raises the pH level of the water.
pH DECREASER – lowers the pH level of the water.
10 TOTAL ALKALINITY (TA) – the amount of carbonate, bicarbonate and hydroxide compounds present in the water that deter-
mines the ability or capacity of the water to resist change in pH. Also known as the ‘buffering’ capacity.
11 ALKALINITY BOOSTER – raises the alkalinity.
12 CALCIUM HARDNESS – the calcium portion of the total alkalinity which represents 70 to 75% of total hardness. Calcium concen-
trations determine whether water is ‘soft’ - too little calcium, or ‘hard’ -too much calcium.
13 CALCIUM BOOSTER – increases the calcium level.
14 TOTAL DISSOLVED SOLIDS (TDS) – a measure of the total amount of dissolved matter in the water (calcium, carbonates, bicar-
bonates, magnesium, metallic compounds, etc.)
15 SEQUESTERANTS (STAIN AND SCALE CONTROLLERS) – keeps dissolved metals and minerals in the water from attacking
the hot tub shell and support equipment components.
16 DEFOAMER – removes foam build-up from the water surface. At best, this is a temporary remedy, as excessive foam is merely a
symptom of improper water balance (typically high organic residue and/or high pH).
17 CARTRIDGE FILTER CLEANER – degreases and cleans cartridge filters.
18 OZONATOR – generates Ozone (a gaseous molecule composed of 3 atoms of oxyg en) and is injected into the hot tub water for
the oxidation of water contaminants.
19 TEST KIT – used to monitor specific chemical residual or demands in the water. May be in the form of litmus strips or liquid drops.
20 PPM – abbreviation for ‘parts per million’, the unit of measurement used in chemical testing which indicates the parts b y weight in
relation to one million parts by weight of water. Essentially identical to the term mg/L - milligrams per liter.

CARTRIDGE FILTER
The cartridge should be cleaned every two to four weeks,
depending on the amount of use. Signs that the filter requires
cleaning include:
• Reduced jet power
• Hazy gray water
• Rattling noise in the pump or filter
• Heater not working
REMOVAL
1 Activate the HOLD/STANDBY mode.
2 Remove the filter cover and place to the side.
3 Rotate the locking flange counter clockwise to disengage.
4 Pull the filter lid upwards, and lift the cartridge element
straight up and out of filter housing.
CLEANING
5 With a garden hose and spray nozzle, hose off the cartridge
element, ensuring to carefully separate every pleat.
6 To remove collected lotions, body oils, etc. soak the car-
tridge in warm water and a filter cleaning/emulsifying compound (available at your HYDROPOOL retailer).
7 A cleaning c ylinder may be purchased from your HYDRO-
POOL Hot tub Retailer.
8 Rinse thoroughly and dry before replacing.
9 Hydropo ol recommends purchasing a spare filter cartridge
so that you always have a clean substitute ready to rotate.
10 After the element has dried - if necessary, lightly brush

EXAMPLE:
1000 liters divided by 13.5 divided by 2 = 37 days.
The hot tub water must be changed when the amount of
dissolved solids becomes excessive, and is usually indicated by “gray” or dull looking water.
WATER SOFTENERS
Never fill a hot tub with water from a water softener, as it
could adversely effect the water chemistry, making it difficult
to maintain proper water balance. If you live in an area with
hard or soft water, give careful attention to your Calcium
Hardness level. Topping Up with soft water is acceptable.
Do not use a wire brush or other devise to
clean cartridge element.
Do not put in dishwasher or washing machine.
RE-INSTALLATION
11 Place the cartridge filter back into the filter housing.
12 Rotate the flange clockwise until it locks in place.
CHANGING THE HOT TUB WATER
A hot tub should be drained every 8-12 weeks, depending on
size and amount of use. If your hot tub is used daily or by a
large number of bathers, the water should be drained more
often. One method to determine the approximate length of
time between water changes is to divide the water volume (in
liters) of your hot tub by 13.5 and then divide by the average
number of bathers each day.
27
EACH TIME BEFORE FILLING THE SPA
1 Check to be sure that the shut off valve is closed (turn
handle clockwise until it stops)
2 Safety cap is securely in place.
3 If the drain valve is facing a wall, leave enough space
between the valve and wall (6” minimum) in order to
have enough space to connect a garden hose.
TO DRAIN THE SPA
1 Turn Power Off
Turn the power off at the spa consoles and deactivate
disconnect switches at the GFCI plug or load center.
2 Locate Spa Drain Valve
The spa drain valve is located on the right side of the
cabinet.
3 Remove Drain Valve Safety Cap
Remove the safety drain cap and store for use when
refilling your spa. Attach a standard garden hose to the
drain valve.
4 Attach Hose & Drain
With the garden hose attached rotate the end of the drain
counterclockwise until it stops turning. Pull the drain to-
wards you and it will begin to drain. To stop draining the
tub simply reverse the process by pushing the drain in
and rotating it clockwise until it will not turn anymore.
Make sure you do not force the drain in so that it is prop-
erly aligned.
CLEANING THE ACRYLIC SURFACE
The acrylic surface can be cleaned and polished using a soft
cloth and acrylic cleaner, available at your Hydropool Retailer.
• Important: Do not use detergents - the re-
maining residues will adversely affect water
chemistry, making it difficult to maintain
proper water balance
• Do Not use abrasive cleaners - damage to
the acrylic surface will occur.
SAFETY HARD COVER
When a hot tub is uncovered, over 90% of heat is lost from the
water surface. This evaporation also affects the chemical balance and could create humidity problems indoors. HYDROPOOL Safety Hard Covers are engineered for maximum thermal efficiency and appearance. They are hi nged in the middle
for easier handling, and the zip fastener allows the tapered
foam inserts to be changed if damaged. The skirt of the safety
hard cover overlaps the lip of the hot tub for a finished fit. The
handles are placed so that even one person can easily carry a
large cover. The locks, with one part fastened to the deck or
skirt, prevent small children or animals from entering the hot
tub. Do not drag the safety hard cover across the hot tub or
decking. Fold the cover first, then lift by the handles. Standing
on the hardcover could cause the tapered foam inserts to
crack, which will lead to water absorption.
NEVER LEAN OR STAND ON YOUR HARDCOVER.
The cover should be cleaned at least twice a year with a vinyl
moisturizer and protector.

CABINET WING-LOCKS
The high quality wing-locks provided on your Hydropool Hot
Tub cabinet not only firmly secure the equipment access
panel, they also serve as convenient handles for removal
and replacement. In order to maintain optimum performance
and extended life, Hydropool recommends lubricating twice
annually with a silicone based lubricant.
RECOMMENDED PRODUCT: Super-Lube silicone
based lubricant (or equivalent) available at major retailers.
CAUTION: Do not use a petroleum based
lubricant, as this will cause premature deterioration of the lock seal.
PROTECTING YOUR CABINET WOOD FINISH
LUBRICATION POINT
HYDROPOOL hot tub cabinets are made from Western cedar and are factory stained. Once stained, cedar weathers
well, and with proper care will maintain its beauty for many
years. In order to maintain the translucent finish and to enhance the wood grain beauty staining must be performed on
a regular basis.
These protective finishes stabilize the wood grain and
build a durable, breathable water-repellent barrier between the wood surface and the elements. These products are available from your local building supply center..

WINTERIZING YOUR HYDROPOOL HOT TUB
In the event that you do not wish to use your hot tub yearround, it is very important that you properly winterize to protect against damage from freezing. Your HYDROPOOL retailer can perform this service for a nominal fee. If you
choose to winterize your hot tub yourself, please follow the
directions outlined below:
• Drain the hot tub entirely see section - DRAINING YOUR
HOT TUB
• Remove and clean the cartridge filter element see section -
CARTRIDGE FILTER
• Using a wet/dry utility vacuum, remove remaining water
from the jet openings, filter cartridge housing, and footwell.
• Either pour or use a turkey-baster where necessary to add
potable biodegradable RV antifreeze to areas such as
pump wet end, jet channels, filter housing, blower channels. DO NOT USE AUTOMOTIVE ANTIFREEZE.
• Important: mixing potable biodegradable RV antifreeze
with water significantly reduces its ability to protect against
freezing. Therefore, it is very important ALL water is removed from the hot tub plumbing before adding.
• Turn pump on for only a few seconds to circulate the antifreeze.
• Unthread and disconnect all unions in the support equipment area. Remove lowest winter drain plug on pump face
plate. Repeat for all pumps, where applicable.
• Cover exposed plumbing connections with plastic bags
and duct tape.
• Where practical, disconnect hot tub support equipment
and store in a dry heated area.
• Install the safety hardcover, and cover the entire hot tub
with a tarp to prevent premature weathering of the cabinet
and the safety hard cover.
• Remove snow build up regularly to prevent damage to the
safety hard cover.
• It is assumed that your HYDROPOOL hot tub has been
properly installed on a reinforced concrete pad to eliminate lifting of the hot tub due to hydrostatic ground water
pressure.
If you are not 100% confident that your
hot tub is properly winterized, please
consult your authorized HYDROPOOL
Hot Tub Retailer. Caution recommends
that an authorized Hydropool Retailer
winterize your hot tub in the initial year.
Damage as a result of freezing is not
covered by the warranty.

GENERAL TROUBLESHOOTING CONTINUED
WHAT TO DO IN THE EVENT OF...
…POWER FLUCTUATIONS
The power supply into your home is, for the most part,
fairly consistent. However, when local power demand is
high, there is a tendency for the voltage entering your
home to drop (sometimes significantly) or fluctuate. This
condition is referred to as a ‘brown-out’. Although safeguards have been built into the system to protect against
this condition, supply voltage may drop low enough, if
even for a second, to cause the system to display a
‘ghost’ message. Should this occur or if the display
shows partial messages, try resetting the system by turning power to the hot tub off, waiting a few minutes, then
turning power on again. If this does not reset the system,
contact your local Hydropool retailer or service organization.
NOTES:
…POWER FAILURE OR SYSTEM FAULT DURING
COLD WEATHER CONDITIONS
If your control system will not reset, (ie. GFCI trips) or if your
pump will not circulate for any other reason, place a low
wattage space heater under the cabinet in the equipment
area. This will delay the risk of freezing while a service appointment is scheduled.
Always follow the manufacturers instructions when locating and placing a portable electric space heater into service.
Ensure that safe clearance to combustible surfaces is maintained. Do not leave
unattended.
