Installation
Accessories needed for the installation
The factory only provides the heat pump. Other necessary items that could be mentioned in the illustrations are to
be provided by the user or installer.
Attention! Please follow the following steps when installing the heat pump:
○ The chemicals have to be added downstream of the heat pump.
○ It is recommended to install a bypass when the flow of the pool pump is more than 20% of the rated flow of
heat exchanger from the heat pump.
○ Install the heat pump on a solid foundation and use rubber below the heat pump to eliminate vibrations and
noise.
○ Installeer de warmtepomp op een solide basis en gebruik de dempende rubber om het geluid en de vibratie te
elimineren.
○ Keep the unit straight up at all times. When the unit has been tilted, it is required to wait 24 hours before re-
starting the heat pump.
○ The heat pump can be installed practically anywhere outdoors. If you wish to install it indoors, please contact
your supplier.
Location
The heat pump can be installed practically anywhere outdoors.
DO NOT
place the unit in a closed area with a limited air volume where the air discharged by the heat pump
will be re-circulated
DO NOT
put the unit next to bushes. This can block the air inlet. Such locations deny a continuous source of
fresh air, which reduces the efficiency of the heat pump and can prevent adequate heat delivery. The picture
below shows the minimum required distances from each side of the heat pump.
6
Distance
Install the heat pump as close to the swimming pool as possible to minimize the loss of heat through the piping.
Put it on a solid base and place some rubber blocks under the heat pump to eliminate vibrations.
Normally, the heat pump is installed within a 7,5 meter radius of the pool. Heat loss is minimal up to distances of
30 meters. The heat loss per 30 meters is estimated at 0.6kw/hour for every 5˚C difference between the pool
water and surrounding of the pipe. This increases the lifespan around 3-5%.
Installation of the valve
The placement of the chlorinator, water balance equipment, and the placement of injectors of chemicals, are very
important aspects of the installation. All addition of chemicals have to be done downstream from the heat pump.
Failure to protect the heat pump unit from chemical damage is not covered by your warranty. A check-valve must
be installed between the heat pump and the chemical feeder to prevent back-siphoning of chemically saturated
water into the heat pump where it will damage the components.

Installation of the pool system
Installation of the bypass
With the bypass set correctly, your heat pump will deliver its best performance. The bypass has to be built as
shown below:
Setting the valves of the by-pass:
○
Install the bypass with all 3 valves entirely open
○
Slightly
close valve 1
○ Close
valve
3 about halfway to adjust the refrigerant pressure

Electrical wiring
Verify the local power supply and the operating voltage of the heat pump. It is recommended to use a separate
circuit breaker (slow type – D curve) for the heat pump together with the proper wiring characteristics. The current
to the heat pump should only be applied when the filter pump is running. For example, a relay controlled by the
filter pump could be used to activate the current to the heat pump. Connect the electrical supply to the junction
box inside the heat pump. All heat pumps require a single-phase connection. Earthing the heat pump is required to
protect you against electrical shocks caused by an eventual short circuit inside the heat pump.
The heat pump is not equipped with a flow switch or any other kind of water flow detection. Therefore, the heat
pump has to be wired electrically together with the filter pump to ensure water flow while the heat pump is
running.
Please consult the Appendix for more information
Start-up procedure
Start-up Procedure - after the installation is completed, you should follow these steps:
1. Turn on your filter pump. Check for water leaks and verify the flow to and from the pool.
2. Turn on the electrical power supply to the heat pump and turn the heat pump ON with the switch. The
heat pump will start after the time delay period has lapsed.
3. After running a few minutes, check whether the air leaving the heat pump is now cooler.
4. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached.
When the set temperature is reached, the unit just shuts off. The unit will now automatically restart (as
long as your pool pump is running) when the pool temperature drops more than 1 degree Celsius below
set temperature. Several days are needed to bring the temperature of your swimming pool water to its
required value.
Water flow switch - the unit is equipped with a flow switch that switches on when enough water has flowed
through the unit and vice versa.
Time delay - the unit is equipped with a 3-minute built-in delay to protect the control circuit components and
to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit
approximately 3 minutes after each circuit interruption. Even a brief power interruption will activate this delay
and prevent the unit from starting until the 3-minute countdown is completed.
Condensation
Since the Heat pump cools down the air about 8 - 12 °C, this causes condense on the fins of the evaporator. If the
relative humidity is very high, this could be as much as several liters an hour. Sometimes this condensation water
is misjudged as pool water and considered to be a leakage.
Guidelines
Water chemistry
Special care should be taken to keep the chemical balance of your swimming pool within limits:
pH 7,0 – 7,4
Free chlorine 0,5 – 1,2 mg/l
TAC 80 – 150 mg/l (10°F – 30°F)
Salt max 8 g/l

○ Failure to keep the swimming pool water between above limits will void the warranty
○ When the concentration of one or more products mentioned above becomes too high, irrevocable damage to
your heat pump may occur. Make sure that you always install water treatment equipment after the heat
pump.
○ When an automatic chemical feeder is installed, it must be installed downstream of the heat pump.
○ A check-valve must be installed between the heat pump and the chemical feeder to prevent back-siphoning of
chemically saturated water into the heat pump where it will damage the components.
Winter-ready
Failure to winterize the heat pump could cause damage to the heat pump and will void warranty.
In areas where freezing temperatures occur, you should protect your pump, filter and heat pump. Perform the
following steps to completely drain the heat pump:
1. Turn off the electrical power to the heat pump at the main breaker panel.
2. Shut off the water supply to the heat pump: close valves 2 and 3 on the by-pass completely.
3. Disconnect the water inlet and outlet and let the water drain from the heat pump.
4. Connect the inlet and outlet again to prevent dirt from entering the connections.
Spring start-up
If your heat pump has been made winter-ready, perform the following steps whilst starting the heat pump again in
spring:
1. Inspect the system for any debris or structural problems.
2. Connect the water inlet and outlet unions firmly.
3. Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through
the heat pump.
4. Turn on the electrical power to the heat pump at the main panel.
Owner inspection
The POWERPACK heat pumps are designed and constructed to provide long performance life when installed and
operated properly under normal conditions. Periodic inspections are important to keep your heat pump running
safely and efficiently through the years. The following basic guidelines are suggested for your inspection:
1. Make sure the front of the unit is accessible for future service.
2. Keep the surrounding areas of the heat pump clear of all debris.
3. Keep all plants and bushes trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a
deflector if needed.
5. If the heat pump is installed under a very sharp roof pitch or under a roof without a gutter, a gutter or
diverter should be fitted to prevent excessive water from pouring down onto the heat pump.
6. Do not use the heat pump if any part has been exposed to an excessive amount of water.
Immediately call a qualified professional technician to inspect the heat pump and replace any part of the
control system, which has been submerged.
10
The heat pump will produce condensation (water) operating. The heat pump base is designed to allow the
condensation to exit through the bottom drain port. The condensation will increase as the outdoor air humidity
level increases. Check the following at regular intervals to ensure proper condensate drainage:
1. Visually inspect and clear the bottom drain port of any debris that could clog the port.
2. Keep the air intake area and discharge area clear of debris so the airflow through the heat pump is not
restricted. The cooler discharge air should not accumulate and be drawn into the side air intake coils.
During normal operation, the heat pump produces ten to twenty liters of condensation per hour. If
condensation drainage is above this range during operation or if water continues to drain from the base
when the heat pump is not in operation for more than an hour, a leak in the internal plumbing may have
occurred. Call a qualified heat pump technician to investigate the problem.
A quick way to verify that the water running through the drain is condensation water is to shut off the unit and
keep the pool pump running. If the water stops running out of the base pan, it is condensation water.
