R.6.3 Rotary heat exchanger
R.6.3.1 Rotor
The rotor is to be checked at least once a year to ensure that it can turn freely and easily. This can be done by removing
the belt drive at the motor and then turning the rotor manually with a hand on the peripheral rotor casing. At the same
time the brush seals are to be checked for damage. The bearings are factory lubricated and do not require any service
lubrication. During operation the rotor can become dirty.
Note:
The rotor can be cleaned by gentle vacuum cleaning and not with compressed air or water.
Check annually that the brush lists 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.
