2. Heat exchanger maintenance (once per year).
Some dust may accumulate on the heat exchanger even in case of regular maintenance of the filters. To maintain high heat recovery
efficiency, regular cleaning is required.
To clean the heat exchanger, remove it from the unit and clean the heat exchanger by using compressed air or a vacuum cleaner. In case
of severe contamination, the heat exchanger can be washed with water. After cleaning, reinstall the heat exchanger into the unit.
Sequence of heat exchanger removal:
1. Unlatch the service panel.
2. Open the panels supporting those with the hand.
3. Remove the drain pan after unscrewing 4 screws.
4. Unscrew 9 self-tapping screws holding the heat exchanger and remove it from the unit.
Be careful when removing the heat exchanger.
3. Fan inspection (once a year).
Even regular technical maintenance of the filters and the heat exchanger may not completely prevent dust accumulation in the fans
which reduces the fan capacity and impairs supply air volume into the premises.
The fans must be cleaned by a service technician.
4. Condensate drain maintenance (4 times a year).
The drain pipes may get clogged with the extracted particles.
Pour some water inside the drain pan and check the pipe for clogging. Clean the U-trap and drain pipe if required.
5. Air intake maintenance (twice a year).
Leaves and other pollutions can clog the supply air grille and reduce the unit performance and supply air volume.
Check the supply grille twice per year and clean it as required.
6. Duct system maintenance (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dust accumulation in the air ducts
which reduces the air quality and the unit performance. The air duct maintenance includes regular cleaning or replacement.
