Power Supply
1. If the supply voltage is too low or too high, it can cause damage and/or result in unstable
operation of the heat pump unit, due to high in rush currents on start up.
2. The minimum starting voltage should be above 90% of rated voltage. The acceptable operating
voltage range should be within ±10% of the rated voltage.
3. Ensure the cable specifications meet the correct requirements for the specific installation. The
distance between the installation site and mains power supply will affect the cable thickness.
Follow the local electrical standards to select the cables, circuit breakers and isolator breakers.
Grounding and Over Current Protection
In order to prevent electrical shock in case of leakage from unit, install the heat pump according to
local electrical standard.
1. Do not interrupt the voltage supply to the heat pump frequently as this may result a shorter life
expectance of the heat pump.
2. When installing over current protection, ensure that the correct current rating is met for this
specific installation.
3. The Compressor, fan coil unit and heat pump water pump all have AC-contactor and thermo
relay protection. Therefore, in the process of installation and debugging, firstly measure each of
the aforementioned components’ current, and then adjust the current protection range of the
thermo relays.
