Commissioning
General
Switch on the power at the mains isolators and then switch on the rocker switch on the front of the indoor units. Set the required
operating temperature on the electronic controller (Master controller on Twin Systems) 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 Master 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.
