Page 8: Unit Design And Operating Principle
VUT 160/250/350 PB EC UNIT DESIGN AND OPERATING PRINCIPLE The unit has the following operating logic: warm stale extract air from the room flows into the unit, where it is filtered by the extract filter, then air flows through the heat exchanger and is exhausted outside by the extract fan. Cold fresh air from the outside flows into the unit, where it is cleaned by the supply filter. - Page 9 Compatibility table of optional equipment and unit models VUT 160/250/350 PB EC A11 — — — — — — — — VUT 160/250/350 PB EC A14 — — — — — — VUT 160/250/350 PB EC A21 — RIGHT-HANDED AND LEFT-HANDED MODIFICATIONS The figure below shows the arrangement of spigots for left- and right-handed modifications.

Page 17: Technical Maintenance
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 (3-4 times per year). Dirty filters increase air resistance in the system and reduce supply air volume. - Page 18 VUT 160/250/350 PB EC 3. 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. 4.
