Swimming pool Heat Pump
3.Installation
The factory only provides the heat pump unit; the other items including an eventual bypass, in the
are necessary parts for the water system, provided by users or the installers.
Attention:
Please follow these steps when installing the heat pump:
1. All feeding of chemicals to the pool water has to be done downstream of the heat pump.
2. Install a bypass when the flow of the pool pump is more than 20% above the rated flow of the heat
of the heat pump.
3. Install the heat pump above the level of the pool water.
4. Install the heat pump on a solid foundation and use the damping rubbers to eliminate vibrations and noise.
5. Always keep the unit straight up. If the unit has been tilted or put on his side, allow 24h before starting the unit.
The unit may be installed virtually anywhere outdoors. For indoor pools please consult your suppliers.
DO NOT put the unit in an enclosed area with a limited air volume where the unit discharge air will be re-circulated.
DO NOT put the unit next to shrubs, which can block the air inlet, Such locations deny a continuous source of fresh
air, which reduce its efficiency and may prevent adequate heat delivery.
The picture below give the minimum required distances from each side of the heat pump.

3.2 How to close to the pool
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 the rubber blocks under the heat pump to eliminate vibrations.

3.3 Distance from the pool
3.4 Installation of the check-valve
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance
from the pool, th e greater the heat l oss from th e piping. S ince the piping is b uried for the most part,
heat loss is minimal for distances of up to 30 meters (15 meters to and fr om th e pump= 30
meters total),unless the soil is wet or the water level is high. Heat loss per 30 meters could roughly be
estimated at 0.6kw-hour (2000 BTU) for every 5 temperature difference between the pool water
and the soil surrounding the pipe which translates to an operation time increase of
- When using automatic chlorine and PH dosage systems, it is of uttermost importance to
protect the heat pump from high concentrations of these chemicals that could corrode the heat exchanger.
Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the heat
pump and it is recommended to install a ch eck-val ve in order to prevent backflow when there is no
water circulation . Damage to the heat pump caused by disregarding any of these recommendations will
invalidate the warranty.

3.7 Electrical wiring
1. Turn on the filter pump, check for leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic control
panel. The unit should start when the time delay period has lapsed .
3. When the unit has been running for a couple of minutes, check if the air leaving the unit is cooler.
4. Check the performance of the flow switch as follows: with the unit running, turn the filter pump off.
The unit should also switch off automatically. If not, the flow switch must be readjusted.
5. All the unit and filter pump to run 24 hours a day until the desired pool water temperature is reached.
When the set temperature is reached, the unit switches itself off. The unit will now automatically
restart (as long as your filter pump is running) when the temperature of the pool water experiences a
drop of more than 1 below set temperature℃ .
Start up procedure- after the installation is completed, you should follow these steps:
3.8 Initial start-up
3.9 Condensation
When the swimming pool water is being heated by the heat pump, the incoming air is cooled down quite
a bit, which can cause condensation on the fins of the evaporator. Condensed volumes can attain severa
l litres per hour underhigh atmospheric humidity. Sometimes, this is wrongfully interpreted as a water leak.
Time delay— - -
.
- .
the unit is equipped with a built in 3 minute start delay included to protect electrical
components and contacts After this time delay, the unit will automatically be restarted. Even a
brief interruption of the power supply will activate the start delay and prevent the unit from starting
immediately. Additional interruptions of the power supply during the delay period will have no effect
on the 3 minute countdown
Water flow switch—
( .
).
the unit is equipped with a flow switch that is switched on when enough water has
flowed through the unit and that is switched off when the water flow becomes too low. e g. when
the filter pump is switched off
Depending on the starting temperature of the pool water and the air temperature, it can take several days
for the water to reach the desired temperature. Covering the pool can drastically reduced this period.
Note:-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
(see table below). 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. Further
connect the electrical supply to the junction box inside the unit. All PRO heat pumps require single-phase connection.
the heat pump is required to protect you against electrical shock caused by an eventual short circuit
inside the unit.
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.

4.1 Water chemistry
pH
Free chlorine(mg/1)
TAC(mg/1)
Salt(g/1)
Important: failure to comply with these limits will invalidate the warranty.
Note: exceeding one or several limits can damage the heat pump beyond repair. Always install water
treatment equipment past the heat pump s water outlet, especially if the chemicals are automatically
added to the water.
A check valve should also be installed between the outlet of the heat pump and this equipment in
order to prevent products from flowing back into the heat pump if the filter pump stops
'
-
.
Special attention should be paid to the chemical balance of the pool water. The pool water values should
always stay within the following limits:
4.2 Winterizing
Important: failure to winterizing could damage the heat pump and will void warranty
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop
below the freezing point, Evacuate all water from the heat pump as follows:
1. Turn off the electrical power supply to the heat pump
2. Close the water supply to the heat pump: completely close valves 2 and 3 of the by-pass
3. Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out of the
unit

4.3 Spring startup
If your heat pump has been winterized, perform the following steps when starting the system in the spring:
1. Inspect the system for any debris or structural poroblems.
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 breaker panel.

4.4 Owner inspection
The PRO heat pumps are designed and constructed to provide long performance life when installed and
properly under normal conditions. Periodic inspection are important to keep your heat pump running
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 shrubs trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage.
5. If the unit 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 unit.
6. Do not use the heat pump if any parts has been under water. Immediately call a qualified professional
technician to inspect the heat pump and replace any part of the control system, which has be submerged.
The heat pump will produce condensation(water) while in operation. 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 increase. 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 condensate per hour. If condensate
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.
NOTE: A quick way to verify that the water running through the drain is condensation water is to shut off the
and keep the pool pump running. If the water stops running out of the base pan, it is condensation water.
AN EVEN QUICKER WAY TEST THE DRAIN WATER FOR CHLORINE--if there is no chlorine present, then
it’s condensation.
