Installation
Commissioning
Switch on the power at the mains isolator and then switch on the rocker switch on the front of the indoor unit. Set the required operating
temperature on the electronic controller and check the system parameters in the controller are as required (the controllers are pre-
programmed in the factory to suggested settings).
Run the system to the required temperature and check system pressures, gas charge and running currents of motors to ensure correct
operation.
Carry out a manual defrost (press the defrost button on the controller for more than 2 seconds) to ensure the defrost period is adequate
to clear any frost build up on the evaporator coil.
Carry out final leak test and ensure all covers are fitted and securing screws are tightened.
Log all information along with system model and serial numbers for future reference.
Ensure that the customer / responsible person is provided with basic operating instructions and where electrical isolators are situated in
case of emergency.
Important Note:
Before starting the system, ensure that all electrical connections are correctly made and tight, service
ports are in the correct position and all covers and guards are fitted.
Important Note:
An anti short-cycle timer is built into the controller to prevent the compressor from stop/starting too
quickly, which can result in the compressor tripping on its internal overload. If the overload trips,
please allow time for it to reset before restarting.
