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.

Non-automated VPA

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.

VPA design is improved continuously and, therefore, some models can slightly dier

from those described in this operating manual.

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

V29EN-03.indd 7 12.10.2016 15:42:54

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!

Fig. 3

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.
