WARNINGS
1Children should NOT use a hot tub
without alert adult supervision.
2Children should not enter a hot tub where
water temperature exceeds body
temperature (37˚C / 98.6˚F).
3As prolonged immersion in water temperatures in excess
of 38˚C (100˚F) may be injurious to your health, we
recommend measuring the water temperature with an
accurate thermometer before entering the tub. We also
recommend establishing lower temperatures and
shorter use periods for young children and/or those
users potentially affected by hot temperatures.
4Do not allow children to submerge their head
under water.
5Do 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.
6Never operate the hot tub pump at high speed without
having all suction and return lines open.
7Always keep the hardcover installed and locked when
the hot tub is not in use.
8People 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 woman 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 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.
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.
SAVE THESE INSTRUCTIONS
IMPORTANT USER SAFETY INSTRUCTIONS
Your physiological response to hot water is very 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.

INDOOR LOCATIONS
If members of your family are not cold winter 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 unique 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 are considering an indoor location, Hydropool
manufactures certain lower profile models in two pieces
(referred to as ‘split’ models) that can be easily moved into
most tight or difficult access locations and then assembled
on-site by your authorized Hydropool dealer.
These ‘split’ and lower profile versions are designed to
accommodate narrow doors or shallow stairwells. Since the
dimension from the seat to the top of the lip is identical to
the “regular profile” units, water submersion, for even the
tallest user, is the same.
Your Hydropool dealer can even arrange for your hot tub to
be shipped without a cabinet or with the cabinet packaged
separately for on-site installation. In many cases the smaller
dimensions of a hot tub wit out a cabinet is all that is
needed to ensure the hot tub can be delivered without wall
or door alterations.
Where the hot tub is being submerged, or a custom deck or
tile is being installed, the cost savings of being able to order
a hot tub without a cabinet is another benefit of choosing
Hydropool.
If you should choose an indoor location, you will find
further information as outlined in the section
“SPECIAL CONSIDERATIONS FOR INDOOR INSTALLATIONS”
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 out, regardless of the climate. Many Hydropool
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.
CHOOSING THE RIGHT LOCATION
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
operating 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 information as outlined in the section
“SPECIAL CONSIDERATIONS FOR OUTDOOR INSTALLATIONS”

HYDROPOOL INDUSTRIES

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 is to allow sufficient headroom
for entry and exit to and from the hot tub
• It is beneficial if the hot tub room is located near wash
room and shower facilities
• The hot tub room should have a floor drain to handle
spillage, 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 small dehumidifier
• Consider plumbing a fresh water tap nearby and a
permanent drain location for the hot tub to eliminate
having to use a long garden hose each time you fill or
drain the hot tub
• Always provide adequate ventilation for the support
equipment
• Consult your local dealer 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,
hydro, 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 your pump(s), controls, drain-valve and
thermal probe are easily accessible and protected
• 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
Hot tub equipment is generally 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 is
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.
SPECIAL CONSIDERATIONS FOR…
ABOVE-GROUND INSTALLATIONS
Where the hot tub is a “stand-a-lone” above-ground
installation to be installed in regions where freeze/thaw
conditions occur, a patio stone or pre-formed paver type
pad may be sufficient if there is no abutting deck(s) to
be damaged during potential seasonal movement of the
ground. The drawback to this type of base is that splash
water could eventually de-stabilize the ground under the
pad, with the resulting support base shift causing damage to
the structure.
For best results, we suggest 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
future shifting.

SITE PREPARATION FOR…
FULL OR 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.
• Non-freezing climates – it is sufficient to ensure that the
base of the hole or cavity created for the tub simply has
a stable, compacted base. The side walls do not need to
be supported, however where the climate permits, should
you choose to backfill directly against the hot tub, a clear
sand backfill is suggested
• Climates where freeze/thaw occurs – it is necessary
that a proper poured concrete base, complete with
sono-tubes, be installed as outlined in the section ABOVE-
GROUND INSTALLATIONS
• Areas with a high ground water table – the concrete
base, as well as a concrete or wood retaining wall to hold
back the earth, is suggested. 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 (gravel) drain system and/or a
sump pump, to prevent ground water flooding damage
to the support equipment or structure
• Install protective waterproof pipe to house any light,
sensor, or topside control cables that could be buried
• Access for future service must be considered at the time
of design and installation. Difficult access can result
in supplemental service labour charges. Consider easily
removable deck materials
OVERALL SUPPORT
Your Hydropool hot tub is equipped with a factory installed
wood cradle support, which helps distribute 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 as
the acrylic lip will crack and possibly break off.
EQUIPMENT ACCESSIBILITY
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
cabinet is designed for both protection and accessibility
• When your hot tub is to be installed fully or partially
in the ground, if you are relocating the equipment
remotely from the hot tub, or if you have ordered a
hot tub without 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 water damage to the motor,
equipment or controls
• Ensure that any opening to the equipment and the
working area around the equipment is large enough to
accommodate a service person
Whenever possible, install the pump below water level
to ensure easy priming. Where above-grade equipment
location is necessary, please ensure that your hot tub is
equipped with the Remote Above-Grade Option Package.
The equipment should be located as close to the hot tub
as possible to maximize jet performance. Where you have
ordered your hot tub with optional remote equipment,
ensure that the equipment is not located more than 5 m.
(15 ft.) from the hot tub. Use only 2 in. flex-pipe or larger
for the pipe runs from the equipment to the hot tub, with
minimal use of elbows or other pipe restrictions.
Install protective waterproof conduit to house any
applicable cords or line extensions such as the sensor and
top-side control cables, light wires or ozone tubing. In
climates where freeze / thaw occurs we suggest that remote
piping be buried below the frost line and that pipe
insulation is applied over all pipes that run from the hot tub
to the remote equipment to maintain energy efficiency.

IN-GROUND INSTALLATIONS
• When submerging the hot tub all or part way below ground level, a concrete base along with a concrete or wood
retaining wall to hold back the earth is suggested. This forms a box or ‘bunker’, in which the hot tub is placed
• Where the climate permits, should you choose to backfill directly against the hot tub, a clear sand backfill is suggested
• Install protective waterproof conduit to house any light, sensor, or topside control cables that could be buried
• ALWAYS ensure that there is adequate drainage via a properly designed gravel drain system and/or a sump pump to
prevent ground water flooding damage to the support equipment
• Access for future service must be considered at the time of design and installation. Difficult access can result in
supplemental service labour charges or damage to your decking
REMOTE EQUIPMENT PLACEMENT
Where the support equipment is being located in a remote
location, the following should be considered:
• The distance from the hot tub should never exceed
5 m. (15 ft.) of pipe length
• Piping diameter must be 2 inches with minimal use
of elbows
• All piping should be insulated to minimize heat loss, and
reduce the risk of freezing
• Equipment should be installed at or below water level.
If it is necessary to install the equipment above grade, the
purchase of the optional Remote Above-Grade Option
Package will be required
• All control cables should be run through a protective pipe
to avoid problems associated with ground settling, frost, etc.
• All support equipment MUST be weather protected, yet
still have adequate ventilation
All Hydropool hot tubs are shipped with a protective
combination layer of bubble 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.
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.
CAUTIONS
• 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

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. Simply place
the hot tub in the desired location and install as outlined
on the following pages.
IMPORTANT NOTES
1Do not lift the hot tub by the plumbing, you may cause leaks.
2Your hot tub can be installed above grade, in the floor
or ground, or half-and-half.
3Ensure that your HYDROPOOL hot tub is properly
supported 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, and/or areas with high water tables) sono-tubes
extending below the frost line should be used.
4Decking should be chosen and constructed in a manner
that minimizes the chance of slipping or falling.
5Level your hot tub using wood shims where necessary,
ensuring that the tapered end extends at least 2 feet
under the unit.
6If you do not have a factory installed foamed cabinet, it
is assumed that you are building your own custom
cabinet, tiling or decking. Please consider the following:
aYour 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.
bWhere the hot tub is not equipped with a factory
installed cabinet, it is the installing electrician’s
responsibility to ensure all electrical equipment is
weather protected.
cAlways provide adequate access for servicing the
support equipment.
dDecking should be constructed to allow repair access
around the entire hot tub.
eIn remote equipment or no-cabinet installations, you
may add extra insulation, but the equipment area must
have adequate cross-flow ventilation.
7Installation of a safety grab rail or reachable support
for use when entering or exiting the hot tub is
recommended.
8The hot tub equipment and all electrical plugs, outlets
and lights within 1.5m (5ft) of the unit must be G.F.C.I
protected. Consult your electrician or local electrical
authority for further details.
9Access 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.
10 A nearby garden hose connection is recommended for
filling and “topping up” the hot tub.
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 2 feet 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.

CHANGING BULBS & LENSES
The coloured light lenses supplied with your hot tub (not
required for units with optional LED lighting) simply push
over the existing clear light lens.
SAFETY HARDCOVER LOCKS
The 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. Always ensure the
safety hard cover is in place and locked whenever the hot
tub is not being used.
OPTIONAL COVER REMOVER
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 dealer.

Although your hot tub was water tested for at least 8 hours 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, pump plugs are tight and o-rings/gaskets are in place.
FILLING, CHECKING AND STARTING YOUR HOT TUB
• Ideally, 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 - p. 27
• Fill the hot tub to the recommended level, approximately
3/4“ (19 mm) from the top of the skimmer opening.
• Visually check all union connections pump plugs
and plumbing for minor leaks. Inthe event of a leak,
ensure all union connections pump plugs are tight and
o-rings/gaskets are in place.
• 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
SPA CONTROL SYSTEMS - p. 16
PUMP PRIMING/RELEASING AN AIR LOCK
• If 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 trapped air (referred to as an ‘air
lock’). 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: the pump(s) should not be allowed to
operate without priming for more than 2 minutes. 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.

• If your hot tub is equipped with the optional Remote
Above-Grade Equipment Package, you should close the
gate valves on either side of the pump, loosen off the lids
on the priming pots, fill with water, re-seal, turn on the
pumps and quickly re-open valves.
• 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 sanitizor.
• 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.
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.

INITIAL START-UP
When you initially power up your hot tub, it will default
to the factory-preset temperature of 100˚F (38˚C), and
filtration cycle of 3 out of every 12 hours see
FILTER CYCLES. Anytime power to your hot tub is
interrupted the system will default to these settings.
TEMPERATURE ADJUSTMENT
The current water temperature is
continually displayed on the topside
control panel.
TO CHECK THE SET TEMPERATURE:
Press the up or down arrow and the display will show the
‘set point’ indicator icon and the set temperature for 5
seconds.
TO CHANGE THE SET TEMPERATURE:
While the display is still showing the set temperature,
press and hold either the up or the down arrow to adjust
the temperature to the desired setting. The temperature is
adjustable as follows:
59˚F to 104˚F in 1˚ increments (15˚C to 40˚C)
PUMPS/JETS FUNCTION
Press this pad to activate the pump
SINGLE PUMP SYSTEM (P1):
1st press – turns on low speed of pump
2nd press – turns on high speed of pump
3rd press – turns off high speed of pump
PUMP AUTOMATIC TIME-OUT
P1 high speed – turns off after 15 minutes
P1 low speed – turns off after 4 hours
CLEAN-UP CYCLE
After P1 high speed is turned off either manually or
automatically, P1 low speed circulates for 1 hour.
FILTER CYCLES
Your spa control system automatically activates P1 low
speed to filter the water twice each day (one filter cycle
every 12 hours). The first filter cycle begins 1 minute after
your spa is initially powered up. The second filter cycle will
begin 12 hours after the start of the first filter cycle. The
duration of the filter cycle (length of time P1 low runs) is
programmable from the topside control panel, and can be
set from 0 -12 hours, where 0 represents no filtration and
12 represents continuous filtration.
Example: selecting 3 would configure the system for 3 hours
of filtration every 12 hours (3 hrs on, 9hrs off).
The low speed pump will start automatically when:
• the system calls for heat. The Heater indicator
lights when the heater is on, and flashes when
the system is calling for heat, but the heater has
not yet activated.
• a filter cycle is activated.
• a freeze condition is detected. See FREEZE
PROTECTION/SMART WINTER MODE
When low speed is already on, the 1st press of the ‘jets’ pad
puts the pump directly into high speed.
PROGRAMMING FILTER CYCLES
To change the preset filter cycles:
Press and hold the pad for 5 seconds.
Press the up or down arrow to select the filter cycle
duration. Once you have selected the filter cycle duration,
press the pad to lock in the setting. The filter cycle will
start immediately.
To prevent excessive water temperature due to long
filtration cycles during warmer weather (referred to as
‘thermal creep’):
If the water temperature exceeds the set point by more than
2˚F for more than 3 hours, the system will turn off the pump.
The ‘Filter’ indicator will flash on/off for the rest of the
duration of the filter cycle – on for .5 seconds, off for .5
seconds, on for .5 seconds, off for 1.5 seconds. Should the
water temperature cool down to 1˚F above the set point
before the filter cycle times out, the system will activate the
pump for the remaining duration of the cycle.

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 pumps
can be primed efficiently and damage to the pumps can be
avoided.
Atinitialpower-up,thisdisplay will appear,
and the system will show 4 sets of
numbers in succession (ie. 100 then 113
then 13 then 240). These numbers
represent the current software revision,
and the system input voltage.
Flashing
After the initial software indicators are
shown, this display will appear. This display
is indicating that the system is in PUMP
PRIMING MODE. This mode will last for
4 to 5 minutes before automatically
exiting and entering the normal
operation mode. You can also manually exit the PUMP
PRIMING MODE after the pumps are primed (see below).
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
pads on the topside control, the pumps can be manually
activated
