Fastener kit - 1 item.
The present user manual consisting of technical details, operating instructions and technical
specication covers the installation of the VUT 300 (301) EV (K) mini EC air handling unit with heat
recovery, VENTS series (hereinafter the unit).
The unit is designed to ensure continuous mechanical air exchange in houses, oces, 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 ltered 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.
Due to the ability to save heating energy by means of energy recovery, the unit is an important
element of energy-ecient premises.
The unit is a component part and is not designed for stand-alone operation.
It is rated for continuous operation.
Transported air must not contain any ammable or explosive mixtures, evaporation of chemicals,
sticky substances, brous materials, coarse dust, soot and oil particles or environments favourable for
the formation of hazardous substances (toxic substances, dust, pathogenic germs).
Relative humidity of transported air must not exceed 80 % at an ambient temperature of +20 °C.
The unit is not designed to be used by children, physically or mentally disabled
persons, persons with sensory disorder or with no appropriate experience or expertise.
The unit must be handled only by properly qualied personnel after the
appropriate safety brieng.
Install the unit to be out of reach of children.
Warning!
The unit is not allowed for operation without properly installed fat lters or with
the clogged fat lters because ingress of oil and sticky substances may damage the
unit.
4VUT 300 (301) EV(K) mini EC
The unit is designed for operation in an enclosed area at ambient temperatures from +1 ºC to +
40 ºC 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 standard:
Unit motors - IP 44;
Unit assembly connected to air ducts - IP 22.
The unit series designations, their main outside and connecting dimensions, appearance and
technical data are given in gures 1, 2 and in Tables 1 and 2.
The unit design is regularly being improved, so some models can slightly dier from those ones
described in this manual.

STRUCTURE AND OPERATING LOGIC
Do not!
• Do not operate the unit beyond the specied 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 medium!
The unit operating principle is as follows (g. 3).
Warm stale air from the premises extracted by the unit is puried in the extract lter, then it passes
through the heat exchanger and then is exhausted outside through the ducts by the exhaust fan.
Clean cold intake air supplied to the unit is puried in the supply lter.
The air passes through the heat exchanger and then fed into the premises by the supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms
it up. The air ows are fully separated.
Heat recovery minimizes thermal energy losses, energy demand and operating costs for heating
during winter time.
The unit is equipped with an electric heater to enable supply air warming up to +30 °C.
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.
All the wireworks with the unit are allowed by a professional electrician, duly authorized for electric
operations.
Warning!
Disconnect the unit from power supply prior to any mounting, servicing, connection
or repair operations with the unit.

MOUNTING AND SET-UP
Mount the unit to provide enough access for maintenance or repair operations, g. 4.
The wall for mounting must have even surface.
Any surface irregularities will lead to unit casing skew and may prevent the unit from operating
properly.
For the unit fastening use the fasteners recommended by the manufacturer for the specied wall
type.
To ensure proper supply air pre-heating install the duct temperature sensor (g. 3) at the
minimum distance of 1 m from the supply spigot.
The supply air duct temperature sensor is installed as follows:
Drill a Ø 9 mm hole in the duct;
Install the sensor into the hole;
Fasten the sensor ange with three self-tapping screws.
It is recommended that the sensor and air duct joint is hermetically sealed.
