3.3. Installation Instruction
3.3.1 Pre-requirements
Equipment necessary for the installation of your heat pump:
① Power supply cable suitable for the unit’s power requirements.
② An optional by-pass can be installed but it has to be either fully open or fully closed. Do not
control water with valves halfway open. This may send a signal of no flow to the PCB board.
③ A set of wall plugs and expansion screws suitable to attach the unit to your support.
④ We recommend that you connect the unit to your installation by means of flexible PVC pipes
to reduce the transmission of vibrations.
⑤ Suitable fastening studs may be used to raise the unit.
3.3.2 Heat Pump Installation
① The frame must be fixed by bolts (M10) to concrete foundation or brackets. The concrete
foundation must be solid; the bracket must be strong enough and anti-rust treated;
② The heat pump needs a water pump (Supplied by the user). The recommended pump
specification-flux: refer to Technical Parameter, Max. lift ≥10m;
③ When the heat pump is running, there will be condensation water discharged from the bottom,
please pay attention to it. Please insert the drainage tube(accessory) into the hole and clip it well,
then connect a pipe to drain off the condensation water. Install the heat pump, raising it at least
10 cm with solid water-resistant pads, then connect the drainage pipe to the opening located
under the pump.
3.3.3 Location and Size
Please comply with the following rules concerning the choice of heat pump location.
① The unit’s future location must be easily accessible for convenient operation and
maintenance.
② It must be installed on the ground, fixed ideally on a level concrete floor. Ensure that the floor
is sufficiently stable and can support the weight of the unit.
③ A water drainage device must be provided close to the unit in order to protect the area where
it is installed.
④ If necessary, the unit may be raised by using suitable mounting pads designed to support its
weight.
⑤ Check that the unit is properly ventilated, that the air outlet is not facing the windows of
neighbouring buildings and that the exhaust air cannot return. In addition, provide sufficient space
