Page 5: Purpose
PURPOSE The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafés, conference halls, and other utility and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream of supply air. The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with high humidity. -
Page 6: Technical Data
www.ventilation-system.com TECHNICAL DATA The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 80 %. In order to prevent condensation on the internal walls of the units, it is necessary that the surface temperature of the casing is 2-3 °C higher than the dew point temperature of the transported air. - Page 7 Overall dimensions of VUT R 400/700/900 WH EC ØD Overall dimensions of VUT R 1200/1500 WH EC 1200 1500 Overall dimensions of VUT R 2000 WH EC 2000 Dimensions [mm] Unit model øD VUT R 400 WH EC 1050 1167 VUT R 700 WH EC 1210 1326...

Page 10: Unit Design And Operating Logic
www.ventilation-system.com 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 by the extract filter. Then the air is moved through the rotary heat exchanger and is exhausted outside with the exhaust fan. -
Page 11: Mounting And Set-Up
MOUNTING AND SET-UP While mounting the unit provide enough access for maintenance or repair work. The minimum recommended clearances between the unit and the adjoining walls are given in the figure below. Before starting the unit make sure that the rotary heat exchanger cells are clean and free from damage. Check the belt tension. The tension force is regulated by the spring on the motor suspension mount. - Page 12 www.ventilation-system.com WATER HEATER CONNECTION Use a pipe spanner for connection of a water heater. Do not apply excessive force while tightening the water works fittings when connecting a water heater. A pipeline system connected to a water heater is designed for normal operation in premises with air temperatures above 0 °C! If the temperature is expected to drop below 0°C it is necessary to provide appropriate thermal insulation or air heating at the site of unit operation.

Page 26: Technical Maintenance
www.ventilation-system.com TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO 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: 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. On elapsing of 3,000 operating hours the unit controller generates the filter replacement or cleaning alert. -
Page 27: Storage And Transportation Regulations
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 cloth or brush. Do not use water, aggressive solvents or sharp objects as they may damage the impeller. 4. -
