TECHNICAL DATA
The unit is designed for operation in an enclosed area at ambient temperatures from +5 ºС to + 40 ºС at relative humidity of 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.
The unit must be grounded.
Hazardous parts access and water ingress protection ratings:
Unit motors - IP 44;
Unit assembly connected to air ducts - IP 22.
The main overall and connecting dimensions as well as the unit view and technical parameters of the unit are given on Fig. 1 and in
Table 1.
The unit design is regularly improved, so some models may slightly dier from those ones described in this manual.

VUE2 150 P ЕС Comfo
The unit design and operating logic are stated on g. 2:
The warm stale air from the premises enters the unit through air ducts where it is stripped of impurities and then extracted through
the heat exchangers by means of the exhaust fan further outside via the air ducts. The cool fresh air from the outside enters the unit
through air ducts where it is stripped of impurities in the supply lter and then extracted through the heat exchangers by means of the
supply fan further into the premises via the air ducts.
The heat exchangers ensure energy exchange between the warm stale air extracted from indoors with the cool fresh air supplied
from outdoors.The air streams remain completely separated in the process. Sensible and latent heat energy recovery reduces heat energy
losses and, consequently, heating costs in the cold season and the air conditioning costs in the warm season.
The units are oered in the left-hand and right-hand variants for installation convenience.
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 ow from outside.
The polymerized cellulose heat exchangers act as air moisture accumulators when the ambient air humidity is too low or as supply
air dehumidiers if the ambient humidity is high. Due to the excellent water-absorbing properties of the heat exchanger material the
unit drainage is not required. The heat exchangers are used to minimise heat energy losses and, consequently, heating costs in the cold
season.
The unit design is shown on Fig. 2.
The units are equipped with a quick-release access panel on special gaskets for easy repair and maintenance.

MOUNTING AND SETUP
The absence of a drain pan in the unit enables its installation in any position provided unhindered access for maintenance.
For best unit performance connect a straight duct section at least 1 m long on both sides of the unit.
The unit spigots must be equipped with grates or other similar devices with the maximum cell diameter of 12 mm to prevent free
access to the fans.
Safety Precautions:
The unit must be mounted on a rigid and stable substructure. Make sure that the installation structure can sustain the weight of the unit.
Reinforce the installation area with beams etc. if required. Prior to installation make sure that the ambient conditions are suitable for the unit
operation. Prior to installation make sure that the casing does not contain any foreign objects such as wrapping lm and paper.
If the abnormal noise is generated at the spiral duct connection point replace the spiral air duct with a exible one to eliminate resonance.
The same eect may be achieved by using exible connectors.
