2.3. Daily maintenance and winterizing
2.3.1. Daily Maintenance
Please don’t forget to cut off power supply of the heat pump
➢Please clean the evaporator with household detergents or clean water, NEVER use gasoline, thinners or
any similar fuel.
➢Check bolts, cables and connections regularly.
2.3.2. Winterizing
In winter season when you don’t swim, please cut off power supply and drain water out of the heat
pump. When using the heat pump under 2℃, make sure there is always water flow.

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
