GENERAL 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 Examine the fan and motor assemblies for lateral and end play in the bearings.
2 Ensure that no water is entering the motor via the electrical gland plate.
3 Check 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 sti󰀨 bristled hand brush. If dirt has accumulated over a long period or the coil is greasy
or sticky, then it may be necessary to use a water hose or chemical pressure hose. Take care not to damage the ns
and comb out if they have become damaged in any way. For epoxy coated coils use a suitable cleaning uid and soft
bristle brush.
Electrical
1 Check all electrical connections for signs of overheating or arcing.
