Page 3: Safety Requirements
SAFETY REQUIREMENTS This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the unit by a person responsible for their safety. Children should be supervised to ensure that they do not play with the unit. - Page 4 Do not use the unit in a hazardous or explosive environment containing spirits, gasoline, insecticides, etc. Do not close or block the intake or extract vents in order to ensure the efficient air flow. Do not sit on the unit and do not put objects on it.
-
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 to recover the heat energy contained in the air extracted from the premises and warm up the filtered stream of supply air, as well as for exhaust ventilation in kitchens, commercial bakeries etc. -
Page 6: Technical Data
VUTR (VUER) 351/651 P(E) EC 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 60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing. In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above the dew point temperature of the transported air. - Page 7 VUTR (VUER) 351/651 D2x6(4) A2/2 VUTR (VUER) 351 1170 1270 1110 VUTR (VUER) 651 1240 1340 1180 www.ventilation-system.com...

Page 8: Design And Operating Principle
VUTR (VUER) 351/651 P(E) EC DESIGN AND OPERATING PRINCIPLE The unit operation is as follows: warm, stale extract air flows through the air ducts into the unit and is filtered. Then the air is moved through the rotary heat exchanger and is exhausted outside through the air ducts with the extract fan. Cold fresh intake air flows through the air ducts into the unit’s supply filter, where it is filtered. -
Page 9: Mounting And Set-Up
MOUNTING AND SET-UP READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT. THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS. The units are available in left-hand and right-hand design. Choosing the right design can improve the ease of installation, shorten the length of the ducts and reduce the number of air duct bends. - Page 10 VUTR (VUER) 351/651 P(E) EC The air ducts must be slipped over the unit flanges until tight. Flexible air ducts must be rigidly fixed with a metal worm clamp. If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects. To prevent uncontrollable access to the fan the spigots may be covered with a protecting grille or other protecting device mesh width not more than 12.5 mm.
- Page 11 SERVICE PANEL The unit is equipped with a hinged service panel for technical and maintenance operations. The unit design enables the user to remove the service panel. Remove the hinge lock and disconnect the grounding wire to remove the service panel. The VUTR (VUER) 651 P(E) EC is equipped with two hinged service panels for repair and maintenance work.

Page 16: Technical Maintenance
VUTR (VUER) 351/651 P(E) EC TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER MAINS BEFORE ANY MAINTENANCE OPERATIONS! 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. Clogged filters increase air resistance in the system and reduce supply air volume. - Page 17 VUTR (VUER) 651 P(E) EC 3. Fan maintenance (once per year). Even in case of regular maintenance of the filters and the heat exchanger, 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.
