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.

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.
