1.4. Kind reminder:
This heat pump has Power-off memory function. When the power is recovered, the heat
pump will restart automatically.
1.4.1. The heat pump can only be used to heat the pool water. It can NEVER be used to
heat other flammable or turbid liquid.
1.4.2. Don’t lift the water union when moving the heat pump since the titanium heat
exchanger inside the heat pump will be damaged.
1.4.3. Don’t put obstacles before the air inlet and outlet of the heat pump.
1.4.4. Don’t put anything into inlet or outlet, or the efficiency of the heat pump will be
reduced or even stopped.
1.4.5. Don’t use or store combustible gas or liquid such as thinners, paint and fuel to avoid
fire.

2.3. Trial after installation
Please check all the wirings carefully before turning on the heat pump.
2.3.1．Inspection before use
① Check installation of the whole heat pump and the pipe connections according to the
pipe connecting drawing;
② Check the electric wiring according to the electrical wiring diagram and earthing
connection;
③ Make sure that the main power is well connected;
④ Check if there is any obstacle in front of the air inlet and outlet of the heat pump
2.3.2．Trial
① 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.
② The user should start the water pump, and check for any leakage of water; Power on
and press the N/ FF button of the heat pump, and set desired temperature in the
thermostat.
③ 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
