penetration:
the motors used in VPA are related to devices of Class 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:

During installation and operation of VPA, there must be fullled the requirements of
this operating manual, «Electric installations arrangement rules», «Rules of consumers»
electric installations technical operation», «Rules of consumers» electric installations safe
operation», valid construction codes, and «Rules of re safety in Ukraine» as well.
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 connect control panel and sensors to control panel and to carry out the
works inside VPA if it is connected to power supply and the switch is in «I» position.(On).
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 CO2
or the powder ller.
USING THE WATER FILLER IS PROHIBITED UNDER ANY CIRCUMSTANCES

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
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
Sensors of the emergency thermal switch shuto circuits and don›t return VPA to
operating condition. To recover VPA it is necessary to push the manual restart «RESET»
button.
Standard set has the remote control panel 5 connected by the communication cable 6to
control system located inside the control unit 7. The lter contamination is monitored by
pressure drop dierential sensor 8. The lter replacement frequency is set on control panel.
the emergency alarm is generated by LED indicator 9 located on the control panel 5.
To monitor and maintain the temperature in the channel, VPA is equipped with channel
temperature sensor. To disconnect VPA from the electric network the power switch is
located on the control unit. VPA is connected to standard circular channels of the air
network.
Special function: to control the fan capacity and the heater operation and to monitor
the lter contamination.
The hinged (pos. 10) or removable cover uses the place for mounting VPA in optimal
manner.

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.
Especially, it concerns the access to cover, which should be open completely, and control
unit located on the side part of case.
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.
