Page 3: Safety Requirements
Do not use the unit in a hazardous or explosive environment containing spirits, gasoline, insecticides, etc. Do not close or block the intake or extract vents in order to ensure the efficient air flow. Do not sit on the unit and do not put objects on it. -
Page 4: Purpose
VPVO PURPOSE The axial pressurisation fan of VPVO series is used for ventilation of industrial, administrative, residential and other buildings. It is also used for pressurisation of fire-fighting equipment and fresh air supply in case of fire. The fan is intended for general ventilation in systems with high air flow rates. -

VPVO CONNECTION TO POWER MAINS DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL. - Page 11 ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.

Page 12: Commissioning
VPVO Problems associated with DOL starting The problems caused by DOL starting may be divided into two groups: An abrupt start causes mechanical shock, jolts in the mechanism, shock removal of free play etc. A heavy start cannot be completed. Let us review three variations of a heavy start: 1. -
