Commissioning Procedure
GENERAL To be read in conjunction with the commissioning sheets provided.
CAUTION Please ensure all documents have been completed correctly and return to Airedale
Technical Support immediately to validate warranty.
PRE COMMISSIONING CHECKLIST
CAUTION ALL work MUST be carried out by technically trained competent personnel.
The equipment contains live electrical and moving parts, ISOLATE prior to
maintenance or repair work.
CAUTION The following commissioning information is based on a complete matched
Airedale system using R410A.
START-UP Switch on the power supply to the condenser and switch the isolator to the on position.
The fan motor starts automatically when the refrigerant condensing pressure reaches the
pre-set value of the pressure regulator (factory set). Therefore to check operation of the
condenser the indoor unit to which it is linked must be running. Refer to
Control Device
Adjustment , on page 18.
General 1 The unit condition is satisfactory.
2 All pipework is complete and insulated where necessary.
3 All fans are able to rotate freely.
Electrical 1 All electrical connections (both mains and control) are properly terminated.
2 The power supply is of the correct voltage and frequency.
3 External fuses/circuit breakers are of the correct rating.
4 The units are properly earthed in accordance with current regulations.
5 All pipework is earth bonded as required.
Refrigeration 1 Check for the presence of a refrigerant charge in the condenser.
2 The system has been evacuated correctly.
COMMISSIONING CHECKLIST
System Readings Condensing temperature (as read on the discharge gauge) should be in the region of
40 to 41°C with an external ambient temperature of 30°C (condensing is normally 10°C.
above ambient) at full fan speed.
Running Checks Once the system has been charged, the following running checks should be carried out:
Check the operation of the fan speed controller by observing an increase in fan speed if
the outdoor coil is temporarily partially blocked.
