The fan air flow in the Supply mode is controlled by means of a DIP switch with an integrated cyclic timer, alternating time of operation
and downtime of the fan every 60 min. The DIP switch is located on the control board.
Using the table, select the desired running time and downtime of the fan for a period of 60 min and set the DIP switch levers to the
appropriate position.

The unit must undergo technical maintenance 3 to 4 times a year. They include general cleaning of the unit and the following
operations:
1. Fan maintenance (once a year).
Some dust may accumulate inside the fans and reduce the fan performance and supply air flow.
Clean the fans with a cloth or a soft brush. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
2. Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air
ducts which reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
3. 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.
