MAINTENANCE The maintenance schedule indicates the time period between maintenance operations.
3 Months At every service visit the following checks should be carried out:
Fan & Motor Assembly 1 Fan and motor assembly for lateral and end play in the bearings.
2 Electrical gland plate to ensure that no water is entering the motor.
3 Fan blades for damage and corrosion.
Refrigeration Circuits 1 Visually examine pipework and components for damage, wear and tear and oil
patches, the latter being indicative of a system leak.
2
Ensure the fan head pressure controller is controlling the head pressure at the
required setting as indicated on the commissioning sheets provided.
The gauges can then be removed from the system. Do not forget to replace the security
caps on the Schrader valves.
Condenser Coil Clean the condenser coil with a stiff bristled hand brush. If dirt has accumulated over a
long period, or tends to be greasy or sticky, then it may be necessary to use a water hose
or chemical pressure hose. Take care not to damage the fins and comb out if they have
become damaged in any way.
For epoxy coated coils use a suitable cleaning fluid and soft bristle brush.
CAUTION Do not use steam for cleaning condenser coils otherwise damage or danger may
result from excessive internal pressures
