THE PROTECTION
PRIOR TO COMMENCING ANY TECHNICAL MAINTENANCE PUT UP A PROHIBITORY

AVOID LIQUID SPILLS ON THE MOTOR! DO NOT USE AGGRESSIVE SOLVENTS AND
SHARP OBJECTS FOR CLEANING!
Maintenance operations of the unit are required 3-4 times per year. They include general cleaning of the unit and the following operations:
1. Filter maintenance (3-4 times per year).
Dirty filters increase air flow resistance, which leads to a decrease in the supply of supply air to the room and creates preconditions for
occurrence of faults. Filters should be replaced as they become dirty, but no less than 3-4 times a year.
To change the filters, remove the unit casing cover (item 2 in the section "Unit design and operating principle").
Rotate the lock that holds the filter. Carefully remove the dirty filter.
Install new filters and cover in reverse order.
For new filters, contact the Seller.
2. Fan maintenance (once per year).
Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance
and supply air flow. Clean the fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may
damage the impeller.
3. Ductwork system maintenance (once in 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 system capacity. Duct maintenance means regular cleaning or replacement.
4. Control unit maintenance (as required).
Flip the lock to release the filter
