UNIT DESIGN AND OPERATING LOGIC
The unit has the following operating logic:
Warm stale extract air from the room flows to the unit, where it is filtered, then air flows through the heat exchangers and is exhausted
outside by the extract fan. Clean cold air from outside is moved to the supply filter. Then filtered air flows through the heat exchangers and is
moved to the room with the supply fan.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. Heat recovery minimizes thermal energy losses and space heating expenses in cold seasons.
The polymerized cellulose heat exchangers are used to recover both sensible and latent energy contained in the extract air and transfer it
to the cold intake air flow from outside.
The polymerized cellulose heat exchangers act as air moisture accumulators when the ambient air humidity is too low or as supply air dehumidifiers if the ambient humidity is high. Due to the excellent water-absorbing properties of the heat exchanger material the unit drainage
is not required. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.

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 (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. The steps to replace
the filters are as follows (refer to the figure below):
1. Unlatch and remove the service panel.
2. Unlatch and remove the drain pans.
5. Turn the latch and remove the filters.
2. Fan maintenance (once a 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. Heat exchanger maintenance (once a year).
Some dust may accumulate on the heat exchanger block even in case of regular maintenance of the filters. To maintain the high heat
recovery efficiency, regular cleaning is required.
• Clean the paper heat exchanger (VUE 200 P and VUTE 200 P models) with vacuum cleaner and then install it back to the unit. Cleaning with
water, abrasive detergents, solvents or sharp objects, which can damage the unit, is not allowed.
• Clean the aluminium heat exchanger (VUT2 200 P and VUTE2 200 P models) with mild detergent solution and then install a dry heat
