| Adjustment and maintenance operations
R.6.4.1 Inspection and replacement of brush seals
Check annually that the brush seals close well. Expect that brush lists should be changed every 5 years — maybe more
often — if necessary.
To ease inspection and service the rotor can be pulled out of the sizes 10, 11, 12, 14 and 16.
R.6.4.2 Cleaning of rotor
With F7 — ePM1 60% filters in both flows — outdoor air and extract air — the counter flows of outdoor air and extract
air through the rotary heat exchanger usually eliminates that dust and particles are stored inside the rotary heat
exchanger.
Note:
The rotor can be cleaned by gentle vacuum cleaning with a brush attachment to the hose of a vacuum
cleaner and not with compressed air or water.
During gentle vacuum cleaning the even removal of eventual dust and particles is provided when the rotor is turning at
a low speed.
R.6.4.3 Motor and belt drive
The bearings are factory lubricated and do not require any service lubrication. The belt drive is to be checked for correct
tightness and that it is undamaged. On smaller AHU, the rotor is fitted with an elastic belt drive and supplied with a re-
serve belt on the rotor. This belt drive does not require service and cannot be shortened. A new belt can be fitted using
specialist tools. On larger heat exchangers the rotor has a V-belt with a belt connector. If the belt is no longer tight, it
must be shortened to a length which enables the motor base frame tightening spring to hold the belt tight. If new
screws are used for the belt connector, they must not have a length which exceeds the thickness of the belt and con-
nector. Remove the excess, if any, with a file.
