3.Installation
The factory only p rovides the heat pump unit; the other items i ncluding an eventual by pass, in the
are necessary pa rts for the water system, provided by users o r the installers .
Attention:
Please follow th ese steps when installing the heat pump:
1. All feeding of chemical s to the pool water ha s to be done downstream of th e heat pump.
2. Install a bypas s when the flow of the pool pump is more than 20% abo ve the rated flow of the heat exchanger
of the heat pump.
3. Install the hea t pump above the level of the p ool water.
4. Install the hea t pump on a solid foundatio n and use the dampin g rubbers to eliminate vi brations and noi se.
5. Always keep the unit stra ight up. If the unit h as been tilted or put on his si de, allow 24h befo re starting the unit.
3.1 Heat pump location
The unit may be in stalled virtua lly anywhere outdoors . For indoor pools p lease consult your suppliers.
DO NOT put the uni t in an enclosed are a with a limited air volume w here the unit disc harge air will be re-circulated.
DO NOT put the uni t next to shrubs, wh ich can block the air inlet , Such locations d eny a continuous source of fresh
air, which r educe its effi ciency and may prevent ad equate heat deli very.

3.3 Distance from the pool
Normally, the po ol hea t p ump is in stall ed wit hin a 7.5 me ter radi us of th e pool. The greater the distance from the
pool, the gre a ter the hea t los s fr om t h e p i pin g. S i nce the pipi ng i s bu ried fo r t he mos t p art, he at lo ss is minimal
for distanc es of up to 30 meters ( 15 meters to and from the pump= 3 0 meters tota l),unless the soil is wet or the water
le ve l is hi gh . Heat lo ss per 3 0 m eters co uld rough ly be estimated a t 0.6kw-hour (2 000 BTU) for every 5 ℃temperature
difference be tw een t he pool water and t he soil surrounding the pipe, which tra nslates to an operation time increase
of 3-5％.
3.4 Installation of the check-valve
Attention- When us ing automat ic chlorine a nd PH d os ag e systems, it is of uttermost im portance to prot ect the heat pump
from high concen trations of these chemicals that could corrode the heat exchanger.
Therefore, su ch sys tems s hould ad d t he che micals in the co nd uits located DOW NSTREAM of the hea t pump an d it is
recom men ded to ins t all a ch eck - val ve i n order to pr eve nt bac kfl ow when the re i s no wat e r ci rcu l ati on. Damag e t o

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 readju sted.
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 temperat ure of the pool water experiences a drop of
more than 1℃ below set temperature.
Start up proce dure- after the installati on is completed, y ou should follow t hese 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 dela y—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 preven t the unit from starting
immediately. Additional interruptions of the power supply during the de lay 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 sever al days
for the water to reach the desired temperature. Covering the pool can drastically reduced this p eriod.
Note:-Verify the local power supply and the operating voltage of the heat p ump. It is recommended to use
a separate circuit breaker(slow type-D curve)for the heat pu mp 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. Fu rther
connect the electrical supply to the junction box inside the unit. All PRO heat pumps require single-phase
connection.
Groundi ng 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: fa ilure to co mply with these limits will invalidate the warranty.
Note: exceeding one or sev eral limits can damage the heat pump beyond repair. Always install water
treatme nt equipment past the heat pump's water outlet, especially if the chemicals are automatically
added to the wate r.
A check-valve should also be installed between the outlet of the h eat pump and this e quipment in
order to prevent products from flowing bac k into the heat pum p 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: fa ilure 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 th e 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-pas s
3. Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out o f the
unit

4.3 Spring startup
If your heat pump has been winterized, perform the following ste ps 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 heat pumps are designed and constructed to provide long perf ormance life when installed and
operated properly under normal conditions. Periodic inspection are important to keep your heat pump running
safe and efficiently all 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 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 wi thout a gutter, a gutter or diverter should
be fitted to prevent excessive water from pouring down onto the un it.
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 p roper 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 s o 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 qualifie d
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 unit 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.
