The hinges are adjustable. The lock plate and guide on the casing should be greased
every 12 months.
Damper
The safety switches must be switched off and locked after the unit has been switched off
before starting any service work.
Function
Normally, the function of the damper is to close off the airways at the outside air and
exhaust air ducts when the unit is switched off. It is important for operating and energy
reasons that the damper works properly.
Check controls
1. Check visually, e.g. through the filter part or another inspection hatch, that the
damper completely seals when the unit is switched off using the normal On/Off
function. (Not with switch disconnector).
2. Make sure the damper opens and closes by starting and stopping the unit.
3. Make sure the sealing strips on the damper blades are intact.
Corrective action
1. Adjust the damper blade and actuator until the blade fully seals.
2. Check the control equipment to make sure everything is correctly connected.
3. Change the sealing strips if needed.
NOTE: Never drill or screw in the end of the damper where the motor shelf and shaft
ends are located.
