INSTALLATION
Electrical Installation
The heat pump draws a large amount of current and it is important that the connection of the
unit to the power supply must be carried out in accordance with the local standards and only
by a licensed electrician.
The power supply system on site and the circuit protection must be designed for the total
current of the unit taking into account the in rush current and the lock rotor amps of the
compressor
– see Technical Data. The circuit breaker must be set no more than 125% of the
units rated load current.
The power supply system on site and the fuses must be designed for the total current of the
unit
– see technical data.
Mains supply cables must be sized to ensure adequate voltage at the heat pump under all
load conditions. Three phase power must be symmetrical, ensuring equal effective voltage
and equal phase angle between consecutive phases. The pump and the compressor rely on
correct phase rotation.
The power supply cable can be fed through the marked access hole at the rear of the heat
pump or through the marked access hole in the base of the heat pump under the electrical
box and into the 10mm terminals through the gland provided. Ensure the phases are match
with the cables installed.
Ensure that all cables are free of hot spots and sharp edges.
Ensure all electrical connections are tight prior to start up.
Power should be provided to the unit for as long as possible
– minimum of four hours – before
start up to ensure that the sump heater will boil off refrigerant from the sump oil. The unit is
now ready to be started up.
The LCD display will give the water temperatures, faults and the performance parameters of
the heat pump.
