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; differential pressure sensor. Application of automation complex allows governing the air flow rate, temperature (heating);...

SAFETY REQUIREMENTS 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.
Non-automated VPA DESIGN AND OPERATION PRINCIPLE VPA provides controlling the air flow rate, air temperature (preheating) and to filter it as well. VPA exterior view is shown in fig. 2. Inside the case 1 there is installed the centrifugal-axial fan 2 equipped with the motor with external rotor and integrated thermal protection.
Non-automated VPA VPA shall be mounted by qualified person or company properly trained and having the required tools and materials. MOUNTING VPA shall be mounted in such way that the arrow on the cover coincides with air flow direction in the system and there is the sufficient space for access for maintenance, service or replacement.
PRIOR TO ANY WORKS IN VPA, IT MUST BE DISCONNECTED FROM THE POWER SUPPLY! CONNECTING TO ELECTRIC NETWORK Depending on VPA type, 230 V / 50 Hz AC or 400 V / 50 Hz AC power supply is used. Connecting VPA to electric network is performed by the qualified electrician only. VPA is connected to electric network by means of durable insulated and thermoresistant wires with the appropriate cross-section area.

Cross-section area values in table 3 are guiding only! While selecting the cross-section area, take into consideration the wire maximum allowable heating dependent on the maximum current, the wire length and its location (air, wall).
