Cleaning
WARNING!
Risk of serious personal injury and/or damage to air handling
unit.
Read and understand the entire chapter "1.5 General safety
messages" before working on, servicing, or inspecting the air
handling unit.
1. Follow item 1 under
Inspection
.
2. Wipe the fan impeller blades to remove any coatings. Use a mild alkaline
detergent.
3. The external surfaces of the motor must be kept clean from dust, dirt and
oil. Clean with a dry cloth. In the event of stubborn dirt, use a mild alkaline
detergent. The motor is likely to overheat inside if thick layers of dirt prevent
air from entering the motor to cool the stator structure.
4. Vacuum clean the air handling unit so that particles will not be blown out into
the duct system.
5. Clean the other parts in the same way as the fan impellers. Check that the
inlet cones are securely mounted.
6. Follow item 10-11 under
Inspection.
