TECHNICAL MAINTENANCE
Maintenance operations of the unit are required 3-4 times per year. It includes general cleaning of the unit and the following operations:
1. Filter maintenance (3-4 times per year).
Dirty filters increase air resistance in the system and reduce supply air
volume. The filters require cleaning not less than 3-4 times per year.
Vacuum cleaning is allowed. After two consecutive cleanings filters
must be replaced. For new filters, contact the Seller.
To clean or replace the filters, detach the removable plates located
on the service side of the unit. After cleaning install the filters and the
detachable plates in the reverse order.
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 the high heat recovery
efficiency, regular cleaning is required. Before removing the heat
exchanger, detach the removable plate located on the service side of
the unit.
To clean the heat exchanger pull it out, drain the water through the
pipes, then flush the heat exchanger with warm detergent solution.
After cleaning install the dry heat exchanger with the drain pan back to
the unit.
3. Drain system maintenance (once per year)
The condensate drainage (drain line) may get clogged by dirt and dust particles contained in the exhaust air. Pour some water inside the drain pan to check the
pipe for clogging. Clean the U-trap and the drain pipe if required.
4. Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts, which reduces the unit
capacity. Duct maintenance means regular cleaning or replacement.
5. Control unit maintenance (if necessary).
The control unit maintenance must be performed by an expert qualified for unassisted operations with electrical installations with the voltage up to
1000 V after careful reading of the user’s manual.
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS.
FOLLOW THE SAFETY REGULATIONS WHEN CARRYING OUT MAINTENANCE.
