SET UP INSTRUCTIONS
• 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.
• 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.
• The heat pump must be positioned to avoid damages caused by water or condensation leaks.
Install suitable drainage outlets or collection containers.
• 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.
• To reduce noise wave echoes, do not install the heat pump in the immediate vicinity of vertical
walls and use the included anti-vibration pads during installation.
• 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.
• Make sure the heat pump is not within the range of any sprinkler or irrigation systems. If
necessary, install suitable protections.

Water Connection and Bypass Kit Installation
The following retail components (not included) are recommended for the hydraulic connections:
• Cut-off valves upstream and downstream from the heat pump to facilitate maintenance and/or
heat pump bypass from the pool water circulation system.
• 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:
Pool Pump Filter Heat Pump Non-return/Check Valve Chemical
Treatment Pool
Heat Pump
Chemical Treatment
Pool
Check Valve
Filter Check Valve
Water Pump
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 liters 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.

Electrical Connection
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.
WARNING
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat
pump.
The heat pump must be connected to a dedicated circuit breaker rated 16 A or more. Make sure
no other appliances are connected to this circuit breaker.
The heat pump is supplied with a power cable and a standard RCD to be plugged directly into a
grounded electrical outlet. The grounded electrical outlet must have a protection grade not lower
than IPX4.
Test the RCD before use:
1. Plug the RCD into a grounded electrical outlet.
2. Press the “RESET” button. The indicator on the RCD should be “ON”.
3. Press the “TEST” button. The indicator on the RCD should be “OFF”.
4. Press the “RESET” button again to start using the heat pump.
Do not use the product if the test failed. Contact a qualified electrician to inspect the electrical
outlet socket.
Initial Operation
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. Plug the heat pump and test the RCD (see “Electrical Connection” section), the display panel
will show all the icons and numbers for 5 seconds and then shows the ambient room
temperature.
3. 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).
4. After a few minutes, check whether the air blowing out of the heat pump fan is cooler.
5. When the filter pump is turned off, the heat pump should also turn off automatically, if not, then
adjust the flow switch (performed by specialist technician only).
6. 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.

SET UP INSTRUCTIONS (continued)
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 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 startup water flow rate.
Refrigerant Gas Pressure Verification
The following table shows the refrigerant pressure versus heat pump working condition. If there
is big difference between them, the machine is probably malfunctioning. Contact a qualified
technician to check the unit.
