P11 LOCATION
1. The air source heat pump must be installed outdoors. It cannot be installed indoors.
2. Never install the unit in a closed room with a limited air volume in which the air
expelled from the unit will be reused, or close to garden plants that could block the air
inlet. Such locations impair the continuous supply of fresh air, resulting in reduced
efficiency, performance and possibly preventing sufficient heat output.
3.During normal operations, the heat pump evaporator fins produce condensation water.
The amount of condensation produced varies according to ambient conditions. The
higher the air humidity, the higher the amount of condensation produced (several
liters per day). The lower heat pump panel acts as a condensation collection tray. Keep
the drain hole clean.
4. The heat pump must be positioned to avoid damages caused by water or condensation
leaks. Install suitable drainage outlets or collection containers.
5. The heat pump must be fixed and installed on a flat, solid, vibration free and level
support (cement slab or prefabricated platform). Do not install the heat pump on
unstable ground.
6. Make sure the pump is not subject to rain water flows from nearby building roofs.
Protruding roofs without gutters could pour significant amounts of water and/or
debris on the heat pump which could damage it. If necessary, install gutters or
discharge outlets to protect the heat pump.
7. Make sure the heat pump is not within the range of any sprinkler or irrigation systems.
If necessary, install suitable protections.
2.2 How to remove the front cover
Lift the front panel up
Loosen the screw
2.3 Condensation Draining Hose Installation
NOTE: The air drawn into the heat pump is strongly cooled by the operation of the heat
pump for heating the pool water, which may cause condensation on the evaporator fins.
The amount of condensation may be as much as several litres per hour at high relative
humidity. This is sometimes mistakenly regarded as a water leak.
1. Slightly tilt the unit to reveal the bottom panel.
2. Attach the drain hose connector (9) to the bottom panel.
3. Attach the wider end of the drain hose (10) to the hose connector and place the other
end into a suitable discharge area.
LOCATION P12
2.1 Location and Space Requirement
2. LOCATION

2.4 Water Connection
The following retail components (not included) are recommended for the hydraulic
connections:
1.Cut-of valves upstream and downstream from the heat pump to facilitate maintenance
and/or heat pump bypass from the pool water circulation system.
2.A non-return or check valve, installed between the pool and the heat pump outlet
fitting, to prevent water reflux.
All chemical feeder or water treatment devices must be installed downstream from the
heat pump and non-return (check) valve. It is important to install a check valve to prevent
chemical saturated water reflux which could damage the heat pump and void the
warranty.
The water circulation system must be arranged observing the following general layout:
Poo→Pump→Filter →Heat Pump→ Non-return/Check Valve →Chemical→
Treatment→ Pool
2.5 Connecting the By-pass Kit
2.6 Typical in-ground pool arrangement
Valve 1:
Slightly closed
(Water pressure increase with just 100 to 200gr)
Valve 2:
Completely open
Valve 3:
Half way open
NOTE: Operation without a bypass or with improper bypass adjustment may result in
sub-optimal heat pump operation and possibly damage to the heat pump, which renders
the warranty null and void.
Although the heat pump is electrically isolated from the rest of
the swimming pool system, this only prevents the flow of
electrical current to or from the water in the pool. Grounding
the heat pump is required for protection against short-circuits inside the unit.
Always provide a good grounding connection outlet. If not sure, contact a
qualified electrician for assistance.
P13 LOCATION LOCATION P14

2.7 Electrical Connection
Caution:
1. Use a properly sized main electrical switch.
The power supply for the heat pump must be grounded.
Electrical wiring must be done by a qualified technician.
The electrical wiring must be carried out in compliance with local regulations. The
electrical wiring must be done with the unit with local regulations.

connected to water
pump directly).
2.8 Before Starting
Make sure the pool is filled with water to the correct level, the skimmer and suction
fittings are below the water level.
To heat the pool water, the filter pump must be running to cause the water to circulate
through the heat pump. The heat pump will not start up if the water is not circulating,
therefore the heat pump must operate together with the filter pump.
After all the water connections have been attached and checked, carry out the following
procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to
the swimming pool.
2. Press the On /Off button on the control unit panel to activate it, the display shows the
water inlet and outlet temperatures. The unit will start up after the time delay expires
(see "Time Delay" section).
3. After a few minutes, check whether the air blowing out of the heat pump fan is cooler.
4. When the filter pump is turned off, the heat pump should also turn of automatically, if
not, then adjust the flow switch (performed by specialist technician only).
5. Allow the heat pump and the filter pump to run 24 hours a day until the desired water
temperature is reached. The heat pump will stop running at this point. After this, it will
restart automatically (as long as the filter pump is running) whenever the swimming
pool water temperature drops 2 degrees below the set temperature.
6. To set the water temperature and program the heat pump, see "Display Control Panel
Operation" section for details.
Depending on the initial temperature of the pool water and the ambient air temperature,
it may take several days to heat the pool water to the desired temperature. A good solar
pool cover can reduce the heating time.
Time Delay
The heat pump has a built-in 1 to 2-minute start-up delay to protect the control circuit
components and avoid excessive restart cycles. The unit will restart automatically

P17 DISPLAY AND OPERATION DISPLAY AND OPERATION P18
3. DISPLAY AND OPERATION
after this time delay expires. Even a brief power interruption will trigger this time delay
and prevent the unit from restarting
immediately. Additional power interruptions during this delay period do not affect the 1
to 2-minute duration of the delay.
Water Flow Switch
The heat pump is equipped with a flow switch to protect it from running without
adequate water flow rate. It will turn on when the pump runs and shut it off when the
pump shuts off. If the pool water level is higher than 1m above or below the heat pump's
automatic flow switch adjustment knob, your specialist technician may need to adjust the
initial start-up water flow rate.

Spring Startup
If the heat pump has been winterized, perform the following steps when starting the
system in the spring:
1. Remove the protective cover and inspect the unit for any debris or structural
problems.
2. Tighten the IN and OUT water connections securely.
3. Check the pool water chemical is balanced, see Pool Water Chemistry" section.
4. Restore water flow to the heat pump, open the valves at the bypass kit and make sure
filter pump is ON.
5. Restore electrical power to the heat pump and test the RCD.
POOL WATER CHEMISTRY
Special care must be taken to keep your pool water chemical balanced within the
following limits:
If the concentration of one or more of the above readings becomes too high, irrevocable
damage to your heat pump may occur. Failure to keep the pool water chemical between
the limits will void the warranty.
Consult with your local swimming pool dealer for water treatment recommendation.
