- The motor is of heavy duty ball bearing construction. The motor is completely sealed and requires no lubrication for the life of the motor.
- Detach fan from the unit.
- Impeller should be specially checked for buil-up material or dirt which may cause an imbalance. Excessive imbalance can lead to accelerated
wear on motor bearings and vibration.
- Clean impeller and inside housing with mild detergent, water and damp, soft cloth.
- Do not use high pressure cleaner, abrasives, sharp instruments or caustic solvents that may scratch or damage housing and impeller.
- Do not plunge impeller into any fluid.
- Make sure, that impeller’s balance weights are not moved.
- Make sure the impeller is not hindered.
- Mount the fan back into the unit. Replace fan guards and connect the fan to power supply source.
- If after maintenance or repair the fan does not start either thermal protection contact activates automatically, contact the manufacturer.

18.3. HEAT EXCHANGER
• Be sure the unit is disconnected from power source before performing any maintenance or repair.
• Proceed to maintenance and repair after any rotation in the fan stopped.
• Clean it once a year.
• The maintenance works for the rotor heat exchanger shall be carried out once a year.
• Ensure that the gaps of the heat exchanger are not contaminated, the seal brushes are not worn, the belt drive is not worn and the clamp as-
semblies are tight.
• The rotor heat exchanger can be easily removed from the unit by disconnecting the power supply cable of the heat exchanger motor (Pic. 1-2).
• The heat exchanger is cleaned using the solution of warm water and non-corrosive toward aluminum alkaline agent or the air stream. It is not
recommended to apply direct stream of liquid as it can harm the heat exchanger.
• It is
NECESSARY
to protect the motor of the heat exchanger from the moisture and liquid while cleaning the heat exchanger.
• CAUTION!
It is forbidden to use the heat exchanger if the fi lters are removed!
