EvoHeat Evo270 Hot Water Heat Pump Manual
3. How it Works
System Principle:
-Refrigerant is compressed into vapor with high temperature
and high pressure when it goes through the compressor.
-On the discharge side of the compressor, the now hot and
highly pressurized vapor is cooled down through the heat
exchange with the water in the tank until it condenses into a
high pressure, moderate temperature liquid.
-The pressure of the liquid refrigerant drops as it passes the
throttling device.
-Finally, the refrigerant absorbs the heat from the surrounding
air and evaporates into vapor with low temperature and low
pressure, where it then it goes into the compressor again.
-The cooled surrounding air could be blown to rooms which
need fresh, cooled air.

your warranty, damage your unit and cause possible injury or death.
Plumbing must comply with AS/NZS3500.4
Indoor Installation Recommendations
•Heat pumps operate most efficiently with warmer air temperatures, and the outlet air from the unit will
always be colder than the inlet air. Therefore, it is advisable to install the unit so it receives the warmest air
temperatures possible and that the cold air is not able to recirculate back into the unit.
•The unit may be able to be installed in an unventilated room exceeding 25m3in volume.
•Venting of cold air is always advisable to prevent the air temperature dropping and lowering the efficiency of
the unit.
•Think of the unit as a 3kW air conditioner for the effect it will have on a closed room.
TO COOL THE ROOM USING THE EVO 270
Install the unit so the outlet from the heat pump is blowing INTO the room. The room MUST have some form of air
outlet otherwise the performance of the unit will suffer significantly.
TO MAINTAIN THE ROOM AT NORMAL TEMPS USING THE EVO 270
Install the unit so the outlet from the heat pump is blowing OUTSIDE the room. The room MUST have some form of
air inlet otherwise the performance of the unit will suffer significantly.
5.5 Cable Connection
The power cable is stored in the back of the unit, it’s for power supply of the unit. The spec of the cable is AWG12.
The unit required an isolating switch as required by local laws.
If the power cord is damaged, it must be replaced by a qualified electrician.
