Electrical Installation
The chiller 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 Australian 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 inrush current and the lock rotor amps of the compressor– see the
brochure. The circuit breaker must be set no more than 125% of the units rated load current.
Mains supply cables must be sized to ensure adequate voltage at the chiller 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. Ensure all
electrical connections are tight prior to starting up.
PREPARATIONS FOR STARTING THE CHILLER
For the initial operation of the chiller, please confirm the following:
1. The power supply voltage and phase should be in accordance with the specifications listed on
the chiller’s marking plate.
2. Check the pipe and return water pipe are connected properly and the valve is open.
3. Fill the water tank with water or coolant before starting the water pump. (Ensure you are using
a suitable coolant according to your requirements)
4. For water-cooled units, please pay attention to the moving direction of the water pump and
confirm the tower fans are not moving in the opposite direction. If the pump is three-phase,
change any two relative phase lines to reverse its direction. Then close the switch after
connections have been made.
