Preparations- Filling and Flushing
1.
Before commissioning, ensure the whole system has been properly flushed and
filled with water.
2.
Check the pipe work system for leaks.
3.
The heating system is filled with water and inhibitor to the required pressure
between 100-200 kPa or 15-30PSI.
4.
Vent air out the system using the air venting valves.
Compressor oil heater
The unit is equipped with a compressor oil heater which heats the compressor oil
before start-up when outdoor temperature is low.
The unit must be in the standby state for 6-8 hours before the unit is switched on
for the first time. This is so the compressor oil heater has the compressor oil at the
correct temp before the FIRST start, this will ensure no damage is done to the
compressor on start up.
Startup and Inspection
1.
Turn the isolator switch on.
Note:
Ensure that the heating control system is in the off position first.
2.
The compressor oil heater must have been operational for at least 6–8 hours before
a compressor start can be initiated.
3.
Start the unit by turning on the heating control system and therefore switching on
the unit.
4.
The water pump will start (the flow switch should operate), then fan motor, and
finally the compressor.
5.
Adjust the flow rate to make water inlet/outlet temperature difference around 5°C.
The temperature difference between ST/RT can be adjusted by increasing the flow
rate by either using circulation pumps or control valve.
