Commissioning Procedure
The following should be carried out with a load on the system, otherwise the unit is likely
to short cycle. The following tests are to be carried out on 1 circuit at a time.
• Switch the door interlocking MCCB to the ON position but again only on the circuit
which is to be tested.
• Adjust the water temperature supply and return set points to match the
system requirements.
To switch the unit ON, use the microprocessor keypad as follows:
Press
Prg
, press , press , press & finally .
COMMISSIONING
CHECKLIST
• Check pressures at suction and discharge ports for correct phase rotation.
If no differential pressure occurs, isolate immediately.
CAUTION
RECORD
• Measure and record the compressor amps once the compressors are fully loaded
and then at each of the unloading stage.
• Measure and record full speed amps of each condenser.
CAUTION
The microprocessor LP setting is adjustable via the micro display. It is
recommended that this setting be 0.4Bar below the equipment freezing point of the
cooling medium ie for water (no glycol) LP micro settings is 3.2barg.
• Ensure that the low water temperature safety cuts out at the correct setting +/- 0.5°C,
to clear the alarms refer to
Alarm Handling section.
• For water (no glycol) application, the recommended setting is 3°C below the design
supply water temperature (to a minimum of 3°C).
• Check the liquid line sight glass is clear and dry.
• Check the superheat setting adjusts the expansion valve to maintain a superheat
setting of 5 – 8°C at all operating loads.
• Check and record the following:
Suction and discharge pressures
Liquid, discharge and suction line temperature
RECORD
Water inlet and outlet temperature
• Ensure the above are all within the design parameters.
• Repeat as follows for each circuit:
• To switch the unit OFF, use the microprocessor keypad as follows:
Press
Prg
, press , press , press & finally .
• To switch the unit ON, repeat above.
The unit is now commissioned and will provide many years of trouble free operation
providing the following maintenance schedule is followed.
