TopMaster Air Handling unit MAINTENANCE INSTRUCTIONS
Replacement parts
Replacement parts and accessories for this air
handling unit can be ordered from the nearest Fläkt
Woods AB sales office. When ordering replacement
parts specify their codes according to the spare parts
catalogue.
Filter
As dust is separated out in the filter the air resistance
increases resulting in a reduced air flow. Regular
filter replacement, with intervals determined by the
concentration of dust in the air, is therefore necessary.
The pressure drop can also be measured with the
manometer RDTZ-07.
It is a good idea to mark the scale of the pressure
gauge in red, just above the value for the recommended
final pressure drop. Order replacement filters and
replacement parts from your nearest sales office.
