3.0 OPERATING PRINCIPLES OF THE THERMODYNAMIC HEAT PUMP
This heat pump comes equipped with a large surface heat collector (A) that allows the maximum heat to be extracted
from the surrounding air. The heat thus recovered is then transferred to the water in your swimming pool via the heat
exchanger. This method of heating generates substantial energy savings compared to conventional electric, gas or oil
pool heaters.
Finally, the cold air is (B) expelled of the unit.
This appliance
delivers the
best value on
the market.

PICTURE 1
IMPORTANT!
SOLAR BLANKET
In order to increase energy savings, we strongly recommend use of a solar blanket when the air is cooler,
especially at night and at the beginning and end of the season. This will minimize heat loss and help reduce your
heating costs.
4.0 ENERGY SAVING
Did you know that at least 43% of heated pool owners choose heat pumps as pool heaters? And with good cause! This
system has the highest output, is the most economical to operate and is the advantageous for maintaining the water
in your pool at a constant temperature, day and night.
Using a pool heat pump continuously to keep the pool’s water temperature at a constant 27 degrees Celsius (80
degrees Fahrenheit) from May to September inclusively costs only one fifth of what it costs to use a natural gas or
propane pool heater.
It also offers other advantages such as no longer worrying about energy supply, not being inconvenienced by
combustion odors and protecting the environment from an ecological point of view.

5.0 INSTALLATION OF YOUR HEAT PUMP
5.1 CHOICE OF INSTALLATION SITE
The installation site is a very important element in getting the most out of your pool heat pump. As described earlier,
the heat pump captures energy from the air and transfers it to the pool water. When choosing the installation site, it
is very important make sure there is enough room around the heat pump that is free of obstacles (wall, trees, hedges
etc). The choice of site should allow easy access to the temperature control panel.
PICTURE 2
A level surface is required to ensure the stability of the heat pump. We recommend using a concrete slab or patio
stone. In addition to durability, these will not be affected by water condensation,* which may drip from the heat
pump evaporator during operation.
(1) Water condensation is the result of hot, humid air coming into contact with the cold surface of your
heat pump's heat collecting coil.

8
5.2 CONNECTING WATER
1. Connect the water line from the swimming pool filter to the «WATER IN» connector located at the base of the
heat pump.
2. Connect the water line returning to the swimming pool to the «WATER OUT» connector located at the base of the
heat pump.
3. Once all connections are made, turn the filter pump on to check water circulation and ensure that all connections
are watertight. The flow rate must be at least 208 litters/minute (55 U.S. GPM / 46 imperial GPM).
A circulation pump that reaches top performance with a flow of 208 litters/minute (55 U.S. GPM / 46 imperial GPM)
must be installed to ensure you achieve sufficient water flow (minimum of 1.5 HP circulation pump is recommended).
PICTURE 3
Connecting your heat pump to your pool’s water line is a simple operation that can be done by you or a qualified
technician. All you will need is flexible pipe, 1½” in diameter inside, and stainless steel clamps.
It is also possible to use rigid PVC pipe but this method is generally more difficult and expensive.
WARNING
TRYDENT heat pumps must never be installed in an enclosed area such as a garage or shed.

9
5.3 BYPASS SYSTEM
The use of a bypass valve system is not necessary for your heat pump to operate properly.
Your heat pump is equipped with a “Full Flow” type heat exchanger that provides optimum performance with a
water flow of 208 litters/minute (55 U.S. GPM / 46 imperial GPM). The heat exchanger was specifically designed to
reduce to erosion to less than 2%. Erosion is caused by water flowing at high speed and the sanding effect produced
by particles suspended in the water (sand, chlorine, etc).
To facilitate maintenance and winterizing, however, we strongly recommend installing a bypass and/or service
valve system.
The design of the heat exchanger makes it easy to drain off the water inside. When the water pipes are disconnected
in preparation for winterizing, because the pool water intake is directly at the base of the cylinder, the cylinder
empties completely by itself, thus eliminating the risk of bursting due to freezing during cold weather.
CAUTION
The titanium heat exchanger has a single wall. This is not suitable for potable water.
CAUTION
The heat pump must be installed between the pool filter outlet and the swimming pool, as close as possible to the
filter pump and the electrical hook-up circuit to minimize connection costs and increase performance. Note that
use of 90° elbows and short elbows should be kept to a minimum (PICTURE).
CAUTION
CHEMICAL PRODUCTS DISTRIBUTOR (CHLORINATOR) (PICTURE )
The titanium condenser has the great advantage of offering almost total protection against the water’s acidity or
chemical products in the water.
Furthermore, in order to decrease the risks of corrosion, if a chemical product dispenser (for chlorine or bromine)
is included with the filtration system, an insulated check valve must be installed downstream in addition to the
check valve in the automatic dispenser.
ATTENTION
NEVER INSTALL THE HEAT PUMP UPSTREAM FROM THE FILTER

5.4 WATER PRESSURE GAUGE
The pipes connecting the different water filtration and heating components often include a large number of bypass
and/or service valves, sometimes leading to inadequate or no water pressure.
PICTURE 5
The pressure gauge should read between 5 and 15 Psi.
A high water pressure reading on the filter gauge does not necessarily mean
that enough water pressure is reaching the heat pump.
A good pressure should be held in the green section. If the pressure is in
the yellow section, you have to do a backwash. If the pressure is in red
section, you have a problem with the out water of the machine. It might
be a bad position of the bypass valve.
5.5 OPERATION OF THE HEAT PUMP
1. The swimming pool water pump must always be ON when the heat pump is in operation. If the swimming pool
water pump is equipped with a timer, make sure that the heat pump’s operating time is synchronized with the
water pump’s operating time, with priority to the pool heater. The pool heater may have to operate for longer
periods than the water pump of the swimming pool.
2. The heat pump may occasionally generate condensation in the form of mist when the relative humidity is at
higher levels.
3. The condensation formed on the heat collector may cause dripping under the heat pump.
4. The use of a bypass valve system is always recommended to facilitate maintenance.
5. When starting the heat pump, the fan will start immediately but the compressor will take between 3 and 5
minutes to start up.
5.6 ELECTRICAL CONNECTION
The TRYDENT heat pump has been designed to enable simple, easy and safe installation. There is no need to open the
heat pump and risk making a mistake in the electrical hook-up.
All our models come with a junction box located at the base of the unit allowing quicker, simpler heat pump hook-up.
Note: You will find the heat pump’s electric plan at the end of this manual and on the inside of the electrical casing
of your unit. This one must be connected to a food of 240v single-phase current.

12
PICTURE 6
Do the connection in the respect of the National, provincial and local codes.
CAUTION
To guarantee your safety and ensure proper operation of your unit, the electrical hook-up should be done by
your POOL EXPERT or a CERTIFIED ELECTRICIAN according to national, state or provincial and municipal codes. A
circuit breaker of sufficient rating and copper wire must be used and it may be necessary to install a ground.
(PICTURE 6)
CAUTION
The power cable ground wire must be connected to the electrical panel and to the ground terminal boards in
the heat pump’s junction box. Improper installation increases the risk of fire, and electrocution or injury.

13
5.7 ECO ENERGETIC CONTACTOR
The eco energy contactor is an option of our electronic chart which makes it possible your Trydent unit to effectively
manage the use of your circulating pump. The latter does not need to function 24 hours a day. Thus energy saving
interesting for a better energetic efficiency.
This option will always privilege the attack of your required temperature versus the time of operation of the
circulating pump.
Generally, the professionals of industry intend themselves to say that the circulating pump can function
approximately 12 hours per day without to affect water quality according to of course the conditions weather or of
the system of treatment of water which you use. Consult your swimming pool professional of the on this subject.
PICTURE 7
WARNING
Units installed within 5 feet of the pool walls must be protected by a ground fault circuit breaker.
WARNING
To guarantee your safety and ensure proper operation of this option, the electrical hook-up should be done by
your POOL EXPERT or a CERTIFIED ELECTRICIAN.

14
5.8 OPERATING OF THE ECO ENERGETIC CONTACTOR
Depending on heat pump instruction (heating required)
(If connected to the electrical box and the contactor)
NOTE: The magnetic contactor is used to intelligently control pool pump while providing better energy efficiency of
your heat pump. (PICTURE 7)
The HP727S features an adjustable minimum filtration period (FIL).
A daily 24-hour cycle is divided into 6 periods of 4 hours (240 minutes).
The adjustable setting values represent the minimum total daily hours that filtration is required.
FIL PARAMETER SETTINGS
(If connected to electrical box)
OFF
2 hours to
23 hours
ON
Pump is always OFF
Pump operates between 2 and
23 hours a day.
Pump is always ON.
1. In OFF mode, the circulating pump needs to be always on or programmed by an external timer.
2. In ON mode, the circulating pump is always on.
The minimum filtration time selector is divided into 6 equal periods per day. E.g. Selection of 4 hours ÷ 6 periods = 40
minutes per period. The circulating pump will therefore operate 40 minutes of each period of 4 hours.
The minimum filtration time that can be selected is 2 hours (6 periods of 20 minutes each).
When the circulating pump is ON, if there is a need for heating during a filtration period:
1. The circulating pump will stay ON until heating is no longer needed.
2. During that period, the minimum filtration time counter meter is always on.
3. If the minimum daily filtration time is reached and heat is still needed, the circulation pump will stay ON until
heat is no longer needed.
If the minimum daily filtration time is reached and heat is not needed, there will still be 15 minutes of circulating time
per period (every 4 hours). This is to sample the pool water temperature in case the water needs to be heated (not
valid if FIL parameter is set to OFF). Whenever the FIL parameter is changed, the daily counter will reset.

15
6.0 HEAT PUMP MAINTENANCE
A) Inspect and clean the pool filter regularly to ensure adequate water flow to the heat pump.
B) Inspect the evaporator and clean it by rinsing carefully, using a garden hose to direct a jet of water from the top
to the bottom to prevent grass, leaves or other objects from blocking the evaporator.
C) Clean the heat pump cabinet with mild soap (dishwashing soap). Do not use abrasive products or products
containing bleach.
D) Make sure that the skimmer is not blocked.

WARNING
SAFETY TIPS
A) A certified electrician should perform all electrical connections (see the high voltage connection diagram).
B) Always disconnect the heat pump before:
Opening the access panel
Cleaning the swimming pool filter
Cleaning the cabinet
Cleaning the evaporator
C) Never sit or place heavy objects on the heat pump.
D) Never put objects in or on the protective grille in order to avoid any risk of injury or breakage

16
Before backwashing, stop the unit by putting the thermostat to the lowest temperature during the cleaning cycle.
Never use the skimmer to add chemicals to your pool water.
These recommendations are important to prolong the life of your heat pump and especially to protect your health.
8.0 WINTERIZING
1. Set the circuit breaker to the OFF position.
2. Drain the heat pump before the first frost. Unscrew all water connections.
WARNING
It is very important that all water connections to the pool are disconnected (bypass valve or other) to allow
complete drainage of the heat pump.
3. Rinse the inside of the heat exchanger cylinder with a stream of city water for about 15 minutes to make sure
chlorine does not remain on the exchanger and cause premature wear to the heat pump. Block the water intake
or outlet and tilt the heat pump to the rear to remove any excess water
4. Block the water intake and outlet with rags or plastic to prevent access by small rodents or other animals.
It is always a good idea to cover the heat pump with the TRYDENT tarpaulin for additional protection, see with your
dealer for more information.
NOTE: When you tilt the heat pump, do not tilt more than 30-35° and always carry it vertically.
RESTARTING
1) Visually inspect the heat pump.
2) Clean the swimming pool filter.
3) Balance the PH Level of the pool water.
4) Reconnect all water intake and outflow connections.
5) Set the circuit breaker back to the ON position.
9.0 OPERATION OF THE ELECTRONIC CARD
WARNING
We recommend maintaining the pH level of the swimming pool at between 7.2 and 7.8. A higher pH level
could damage the heat pump and other equipment and also void the warranty. Also, check the chlorine and
the hardness of the water. (PICTURE 8)
