This operating manual is joined with technical description, operation instruction and
technical certicate for Ventilation Intake Unit (hereinafter referred to as «VPA») and
contains information concerning the mounting, rules and warnings essential for proper
and safety VPA operation.
Prior to commencement of operation, carefully read this manual and observe the
instructions given in it.
VPA is designed for supplying the cleaned and heated outer air, free of ammable or
explosive substances, chemically active fumes, dust, carbon black, etc., to residential and
public buildings (individual houses, oces, hotels, conference-halls and other premises),
and for providing the required quality of the air. The unit is mounted in enclosed and dry
room with ambient temperature +1 °C to +40 °C.
VPA is mounted in the air-distributing system by connecting to air-duct of round
channels.
VPA represents the component part and is not a subject of independent operation.
VPA without automation components an be additionally equipped with adapted to
it «VENTS» automation complex composed of: control panel; control unit; heater control
opto-triac module; channel temperature sensor; dierential pressure sensor. Application of
automation complex allows governing the air ow rate, temperature (heating); air ltration
monitoring, that allows signicant saving of electric energy. This Unit doesn΄t include the
automation complex.
Delivery set contents:
VPA (appropriate type) — 1 pc.
operating manual — 1 pc.
transportation package: wooden box — 1 pc.

Protection rating from access to dangerous parts and water penetration is IP 44
(protection against the bodies with size more than or equal to 1.0 mm; protected against
the water splashes); — VPA installed in the pipeline is related to devices of Class IP 22
(protection against the bodies with size more than or equal to 12.5 mm; protected against
the water drops falling down vertically when the casing is deVPAted at angle of 15 °).
Example of design letters:
Ventilation input unit VPA, diameter of connecting tubes 150 mm, heater power 6.0 kW,
phase connection: «VENTS VPA 150-6.0-3»
Basic technical parameters correspond to values shown in table 1. Overall and mounting
dimensions are shown in table 2 and in g. 1.

Installation and operation of VPA unit must be compliant with the provisions of all the
applicable local and national construction, electrical and technical codes and standards.
VPA relates to electric equipment and, therefore, it is necessary to observe the safety
rules concerning the electric equipment handling.
To servicing and mounting this product there are admitted the persons authorized to
independent work on electric installations up to 1000 V and carefully studied this operating
manual.
VPA must be used according to its designation only.
It is prohibited to carry out any works on VPA if it is connected to power supply.
Never remove the cover if VPA is energized!
Before commissioning VPA check:
correctness of mounting in ducts, correctness of connection to power supply including
grounding and external safety circuit-breakers.
SAFETY REQUIREMENTS
In case of sensor-thermal switch operation it is necessary to de-energize VPA,
identify the cause of this operation, eliminate this cause, and only then reenergize
the unit.
Do not use VPA for operation with air-dust mixture.
VPA operation without reliable grounding is prohibited.
In the event of re the VPA is extinguished by means of materials with CO2or
the powder ller.
USING THE WATER FILLER IS PROHIBITED UNDER ANY CIRCUMSTANCES

Non-automated VPA
VPA provides controlling the air ow rate, air temperature (preheating) and to lter it as
well. VPA exterior view is shown in g. 2.
Inside the case 1 there is installed the centrifugal-axial fan 2 equipped with the motor
with external rotor and integrated thermal protection. The motor is inside the operating
turbine and doesn›t require any maintenance. The air ow rate is controlled by means of
the fan 2 speed switch with 3 speed steps. The air lter 3 of EU4 ltration class per DIN
24185 is located in the case 1 guiding rails from the fan 2 tube. For air preheating, the
channel electric heater 4 with circular tube is mounted from the pressure tube. The electric
heater 4 has the thermal protection against the overheating: safety device with automatic
restart of VPA and emergency shuto with manual recovery:
50° thermostat for VPA automatic switching-o and consequent switching-on after the
heater housing has cooled.
90° thermal switch with automatic restart of VPA using manual recovery.
Sensor of the emergency thermal switch shutos circuits and doesn›t return VPA to
operating condition. To recover VPA it is necessary to push the manual restart «RESET»
button.
VPA is connected to standard round channels of the air network.
The hinged (pos. 5) or removable cover uses the place for mounting VPA in optimal
manner.
DESIGN AND OPERATION PRINCIPLE
ATTENTION! VPA operation without the thermal protection switches for
tubular electric heating elements is PROHIBITED!

VPA shall be mounted in such way that the arrow on the cover coincides with air ow
direction in the system and there is the sucient space for access for maintenance, service
or replacement.
VPA can be mounted on at surface or hanged at threaded rod; the unit shall be
thoroughly secured to eliminate the risk of releasing or falling down (it is necessary to take
into consideration the VPA weight and material to which the unit is attached), using all
mounting L-holders containing the antivibration inserts and attached to unit base (g. 3)
VPA is designed for mounting in the round ducts;
we recommend to attach the pipeline VPA the exible tting to prevent the noise and
random oscillation transmission;
the size of connected channel must coincide with the size of hole in VPA
VPA distance to duct turns shall be at least by two times less than the channel connecting
diameter.
MOUNTING
VPA shall be mounted by qualied person or company properly trained
and having the required tools and materials.
