SAFETY REQUIREMENTS

DO NOT!

• Do not operate the unit beyond the specied temperature range or in an aggressive

and explosive medium.

• Do not connect clothes dryers or similar equipment to the ventilation system.

• Do not operate the unit in the air and dust mixture environment.

WARNING!

Mounting, servicing, connection and repair works are allowed after the unit is

disconnected from power mains.

While operating and mounting the unit consider the requirements of the present operation manual

as well as general requirements of all applicable local and national building and electrical codes and

standards.

Ground the unit before operating!

Before connecting the unit to power mains make sure that the unit is free of any visible damages or

any other foreign objects inside the casing that can damage the impeller blades.

Connection of the unit to power mains by duly qualied electricians only!

CONDENSATE DRAINAGE

The unit is equipped with a drain pipe for condensate drainage (only for the unit VENTS VUT 100

P mini). The connection of the unit to drain system is shown in g. 5.

Connect the condensate drain pipe (1), U-traps (3) and the drainage system with metal, plastic

or rubber pipes .

The pipes should be sloped down by min. 3 degrees.

Before starting operation of the unit ll the system with water and check that U-trap is always

lled with water. Make sure that the water drainage is correct. Wrong connection to drainage system

may result in unwanted water ingress to the room.

The unit with a condensate drainage system is designed for operation at the ambient tempera-

ture above 0C. If the unit is operated in the environment below 0C it must be thermal-insulated and

equipped with heating.

Check the correct installation of the U-trap considering low pressure in the system produced

by the supply fan (g.5). In this case the maximum developed pressure is 115 Pa and dimension A is

about 100 mm and dimension B is about 80 mm.

Fig. 5

To gain the best performance of the unit while mounting provide a straight 1 m duct section

in front and behind the unit . If the unit is installed at the air duct inlet or outlet it shall be equipped

with a grille with the mesh width up to 12.5 mm or any other protecting device to prevent free access

to the unit fans.

UNIT CONNECTION TO POWER MAINS

Cut power supply o before any operations with the unit. The unit shall be con-

nected to power mains by duly qualied electricians. The rated values of the electrical

parameters are shown on the rating plate. Any modications of the internal connections

are not allowed and will void the warranty.

The unit is rated for connection to single-phase ac 230 V / 50 Hz power mains.

For the unit connection use insulated, durable and heat-resistant wires, cables not less than 0.75

mm2. The unit is connected to power mains through the terminal block in compliance with the wiring

diagram and terminal designation on the g. 6. The wiring diagram is also shown inside the terminal

box. The terminals on the wiring diagram are marked in compliance with the actual marking in the unit.

Route the wires into the terminal box through an airtight screwed cable gland located at the side

wall of the unit to preserve the electric rating class.

Connect the unit to power mains through the external magnetic circuit breaker integrated into the

xed wiring system with min. overload protection 1A.

UNIT OPERATING AND CONTROL LOGIC

The operating logic of the unit is as follows.

Sensible heat energy contained in the extract air ow is transferred in the VENTS VUT 100 P mini

unit heat exchanger to the cold intake air ow from outside to warm it up before supplying it to the

room.

Both sensible and latent moisture energy contained in the extract air are transferred in the VENTS

VUE 100 P mini unit heat exchanger to the cold intake air ow from outside to warm it up before sup-

plying to the room .

The paper heat exchanger of the VENTS VUE 100 P mini unit operates as a moisture balancer in

case of too low outdoor humidity or as a air dryer in case of high outdoor air humidity. Due to high

hygroscopic features of the heat exchanger materials the unit does not need condensate drainage.

Due to energy and heat utilization by the heat exchanger minimizes thermal energy losses and

saves heating costs during cold season.

Air ow in the unit in regulated by the two-speed switch P3-1-300, further the switch. View of the

switch as shown in g. 7.

The thermostatic switch 6 (g. 2) in the unit casing provides frost protection of the heat exchanger

during cold season. The thermostatic switch switches the supply fan o if the heat exchanger needs to

be heated with the extract air heat energy.

The thermostatic switch is regulated manually by turning the control knob to set the required ther-

mostatic switch setpoint. The threshold switching value is set individually depending on the operat-

ing conditions of the unit. The recommended thermostat setpoint is +3ºC (factory setting). Rotate the

switch control knob to set the setpoint threshold.
