MAINTENANCE
RECOMMENDATIONS
A periodic visual check of the following is recommended:
-
Cleanliness of the coil
-
Fan operation
-
Position of axial fans in their collar
State of each axial fan (tightness to shaft, mechanical state of blades etc)
-
If the unit is stopped for long periods of time, the fan motors should be run for at least two hours each week.
CLEANING
The coils should preferably be cleaned:
With compressed air
-
By brushing with non-metallic materials
-
With clean water spray (3 bars maximum at a distance of 1.5m).
-
Avoid spraying motors with water. The electrical supply will have to be switched off during this operation.
-
Avoid all aggressive detergents which may cause eventual corrosion.
FAN MOTOR CHANGE
This operation can only be undertaken once the electrical supply has been switched off (consignation).
Under this condition only, the access to fan motors is authorized.
Remarks :
If a fan motor needs to be changed, care should be taken to unplug all purge holes during reinstallation (to enable the condensation to
escape).
