a. Location and water pipe connection
The inverter pool heat pump should be installed in a good ventilation place.
1) The frame must be fixed by bolts (M10) to concrete foundation or brackets. The concrete foundation
must be solid and fastened; the bracket must be strong enough and antirust treated;
2) Please don’t stack substances that will block air flow near inlet or outlet area, and there is no barrier
within 50cm behind the main machine, or the efficiency of the heat pump will be reduced or even
stopped;
3) The machine needs an appended pump (Supplied by the user). The recommended pump
specification-flux: refer to Technical Parameter, Max. lift ≥10m;
4) When the machine is running, there will be condensation water discharged from the bottom, please
pay attention to it. Please hold the drainage nozzle (accessory) into the hole and clip it well, and then
connect a pipe to drain the condensation water out.
b. Water pipe connection

Inverter heat pump solution
10
The inlet and outlet water unions can’t stand the weight of soft pipes. The heat pump must be
connected with hard pipes!
DO NOT install water pipes in a way that they pass behind the heat pump's evaporator. In case this
cannot be avoided, cover the pipes with thermal insulation foam.
2. Wiring
a. Connect to appropriate power supply, the voltage should comply with the rated voltage of the
products.
b. Earth the machine well.
c. Wiring must be handled by a professional technician according to the circuit diagram.
d. Set leakage protector according to the local code for wiring (leakage operating current ≤ 30mA).
e. The layout of power cable and signal cable should be orderly and not affecting each other.
3. Electric wiring diagram
For power supply: 230V 50Hz

F. Testing
1. Inspect heat pump before use
a. The ventilating device and outlets are operating adequately and are not obstructed.
b. It’s prohibited to install refrigeration pipe or components in corrosive environment.
c. Inspect the electric wiring on basis of the electric wiring diagram and earthing connection.
d. Double confirm the main machine power switch should be off.
e. Inspect the air inlet and outlet.
2. Leakage detection notice and method
a. Leakage checking is prohibited in closed area.
b. The ignition source is prohibited during the leakage inspection. A halide torch (or any other detector
using a naked flame) shall not be used.
c. Leakage detection fluids can be applied with most refrigerants but the use of detergents containing
chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe.
d. Vacuumize completely before welding. Welding can only be carried out by professional personnel in
