TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS.
Maintenance operations of the unit are required 3-4 times per year. Maintenance includes general cleaning of the unit and the following operations:
1. Filter maintenance.
Clogged fi lters increase air resistance in the system and reduce supply air volume.
The fi lters require cleaning not less than 3-4 times per year.
On elapsing of 3,000 operating hours the unit controller generates the fi lter replacement or cleaning alert. Clean or replace the fi lters and reset the
hour meter.
Vacuum cleaning is allowed.
After two cleanings fi lters must be replaced.
For new fi lters contact the Seller.
Sequence of fi lter removal:
1. Disconnect the unit from power mains.
2. Remove the service panel.
3. Pull the fi lters to remove.
2. Heat exchanger maintenance (once per year).
Some dust may accumulate on the heat exchanger block even in case of regular maintenance of the fi lters. To maintain the high heat recovery effi
ciency,
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.
After cleaning re-install the heat exchanger into the unit.
Sequence of heat exchanger removal:
Sequence of fi lter removal:
1. Disconnect the unit from power mains.
2. Unlatch and open the service panel.
3. Disconnect the rotary heat exchanger and then pull it to remove.
3. Fan maintenance (once per year).
Even in case of regular maintenance of the fi lters, some dust may accumulate inside the fans and reduce the fan performance and supply air fl ow.
Clean the fans with a soft cloth or brush.
Do not use water, aggressive solvents or sharp objects as they may damage the impeller.
4. Supply air fl ow control (twice per year).
The supply duct grille may get clogged with leaves and other objects reducing the unit performance and supply air delivery.
Check the supply grille twice per year and clean it as required.
5. Ductwork system maintenance (once in 5 years).
Even regular fulfi lling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air ducts which leads to
air pollution and reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
