2.2.2. Heat pump installation.
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;
The heat pump needs a water pump (Supplied by the user). The recommended pump
specification-flux: refer to Technical Parameter, Max. lift ≥10m
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.
2.2.3. Wiring & protecting devices and cable specification
Connect to appropriate power supply, the voltage should comply with the rated voltage of the
products.
Well earth the heat pump.
Wiring must be connected by a professional technician according to the circuit diagram.
Set breaker or fuse according to the local code (leakage operating current ≤ 30mA).
The layout of power cable and signal cable should be orderly and not affecting each other.

be increased. The signal cable can be extended to 50m at most.
2.3. Trial after installation
Please check all the wirings carefully before turning on the heat pump.
2.3.1．Inspection before use
Check installation of the whole heat pump and the pipe connections according to the pipe
connecting drawing;
Check the electric wiring according to the electrical wiring diagram and earthing connection;
Make sure that the main power is well connected;
Check if there is any obstacle in front of the air inlet and outlet of the heat pump
2.3.2．Trial
The user is advised to start the water pump before the heat pump, and turn off the heat pump
before the water pump for long life circle.
The user should start the water pump, and check for any leakage of water; Power on and press
the ON/OFF button of the heat pump, and set desired temperature in the thermostat.
In order to protect the heat pump, the heat pump is equipped with start delay function. When
starting the heat pump, the fan will start to run in 3 minutes, in another 30 seconds, the
compressor will start to run.
After pool heat pump starts up, check for any abnormal noise from the heat pump.
Check the temperature setting.
