5.3. Trial after installation
Please check all the wirings carefully before turning on the heat pump.
5.3.1.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
5.3.2.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
5.4. Maintenance and winterizing
5.4.1 Maintenance
The maintenance should be carried out once per year by qualified professional technician.
➢Cut off power supply of the
heat pump before cleaning,
examination and repairing .
