r. 4.2 Dampers
Rubber seals between the damper blades themselves and between the damper blades and the frame are
to be checked once a year. These seals are not to be lubricated or treated in any other way.
Each damper blade is connected by a pivoting system. The steel rods and brass bushes do not require
lubrication
.
The damper blades are fitted with synthetic bearings requiring no lubrication. Air ‐ tightness of the damper,
when the damper motor is in the closed position, must be visually checked once a year. The damper motor
is to be adjusted if the damper does not close tightly.
r. 4.3 Rotary heat exchanger DVC
r. 4.3.1 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. The
rotor can be cleaned by blowing through with compressed air.
To ease inspection and service the rotor can be pulled out of the sizes 10, 15, 20, 25 og 30.
