Service & Maintenance
The units are designed to give long life operation with minimum maintenance. However, they should be routinely checked and the
following service schedule is recommended under normal circumstances:
1.
Indoor and Outdoor units – Inspect at regular intervals
Check for refrigerant leaks on all joints and fittings.
Check mountings for tightness and wear.
Inspect pipework for any damage.
Check all electrical connections.
Ensure that no abnormal noise or vibration is detected during test run.
2. Condenser & Evaporator Fan Motors & Blades – Clean and inspect at regular intervals
Check for abnormal noise, vibration and fan imbalance.
Ensure that the fan motors are clean and spin freely.
Check that the fan blades are clean and free from restriction and damage/imbalance.
Note:
The Fan Motors are pre-lubricated and factory sealed so no maintenance is necessary.
3.
Condenser & Evaporator Coils – Clean and inspect at regular intervals
Check and remove the dirt and debris between the fins using a soft brush and/or a suitable chemical coil cleaner then rinse with
clean water.
Check and remove any obstacles that may hinder the airflow through the coils.
Repair any damage to fins and ensure any guards are fitted correctly.
DO NOT USE HIGH PRESSURE WASHERS ON COILS – THEY DAMAGE THE FINS.
4. Controls
Check controller settings and operation.
Check calibration of temperature probe reading.
5.
Power Supply – Inspect at regular intervals.
Check the running current and voltage for the units.
Check the electrical wiring and tighten the wires onto the terminal blocks if necessary.
6. Refrigerant Charge
Check the refrigerant charge by ensuring that the system is operating correctly and the system pressures are as expected.
Carry out a full leak test.
7. Unit decommissioning and disposal
At the end of the system’s useful life, a suitably qualified engineer should decommission it. The refrigerant and compressor oil
are classed as hazardous waste and as such must be reclaimed and disposed of in the correct manner, including completion of
waste transfer paperwork. The system components must be disposed of or recycled as appropriate in the correct manner.
Important Note:
Warning! – Disconnect the mains electrical supply before servicing or opening the
units.
