withdraw DHW antifreeze. If the water pump starts over 30 minutes, withdraw DHW
antifreeze.

4.4.6 AC anti-freeze

If the heating supply or return temperature of the heat pump falls below value of parameter
P25, heating
frost protection will be activated. Depending on the outside air temperature, one of the
following actions will be started:
• At an outdoor temperature of ≤ +15 °C: compressor for heating will start
• At an outdoor temperature of ≥ +15 °C: water pumps C1 and C2 will start
If the heating supply or return temperature is above +10 °C or the water pump has worked
longer
than 30 minutes, heating frost protection will be deactivated automatically.
When heating supply or return temperature is below +10 °C and the water pump has
worked longer than 30 minutes, time calculation will start and will record how many times
the deactivation condition appears. If it appears twice within 90 minutes, the error code E24
will be displayed.

4.5 Commissioning

4.5.1 Preparations

1) Compressor Heater
As mentioned above, if the temperature is lower than 10°C, the compressor heater will heat
the compressor for 3-10 minutes before the first start up.
2) Filling and Venting
The hydraulic installation must include a filling valve, air vent valves and the
necessary hydraulic components for correctly filling it.
To fill the heat pump, open the filling valve until the pressure gauge located on the back of
the machine shows a pressure of 1~1.5 bars. The heat pump has an auto air vent on the
top of the heat exchanger's (condenser) flow tube. Open it during the filling process and
wait for the water to begin flowing out.
The air should also be bled from the rest of the installation using the air vent valves provided.
Filling should be performed slowly, thus helping the evacuation of air from the water circuit.
Close the filling valve after filling.
To comfortably access the heat pump air vent valve, open the top cover and side panel of the
heat pump.
IMPROTANT: Switching on the heat pump with no water inside could
result in serious damages.
