2.3. Daily maintenance and winterizing
2.3.1. Daily Maintenance
Please don’t forget to cut off power supply of the heat pump
①Please clean the evaporator with household detergents or clean water, NEVER use
gasoline, thinners or any similar fuel.
②Check 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

exchanger inside the heat pump will be damaged.
2. Installation and maintenance
The heat pump must be installed by a professional team. The users are not qualified to
install by themselves, otherwise the heat pump might be damaged and risky for users’
safety.
2.1. Notice before installation：
2.1.1. The inlet and outlet water unions can’t bear the weight of soft pipes. The heat pump
must be connected with hard pipes!

For installers and professionals
- 8 -
2.1.2．In order to guarantee the heating efficiency, the water pipe length should be ≤10m
between the pool and the heat pump.
2.2. Installation instruction
2.2.1. Location and size
The heat pump should be installed in a place with good ventilation

For installers and professionals

※ Above data is subject to modification without notice.
2.2.2. Heat pump installation.
①The 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;
②The heat pump needs a water pump (Supplied by the user). The recommended pump
specification-flux: refer to Technical Parameter, Max. lift ≥10m
③When 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
①Connect to appropriate power supply, the voltage should comply with the rated voltage
of the products.
②Well earth the heat pump.
③Wiring must be connected by a professional technician according to the circuit
diagram.
④Set breaker or fuse according to the local code (leakage operating current ≤ 30mA).
⑤The layout of power cable and signal cable should be orderly and not affecting each
other.
