DESIGNATION KEYTECHNICAL DATA

The unit is rated as a Class I electrical appliance.

Overall and connecting dimensions [mm]

DESIGN AND OPERATING PRINCIPLE

Depending on the model the fan casing is made of polymer-coated steel, aluminum, or galvanized steel. The units feature electronically commutated (EC) direct current motors with an external rotor and centrifugal impellers with backward curved blades. EC motor is free of friction and wears parts such as a commutator and brushes. These components are replaced by a maintenance-free electronic circuit board.
In conditions of low temperatures and high humidity, in order to avoid freezing or water ingress into the duct, the unit must be operated continuously.

MOUNTING AND SET-UP

BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER).
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.

• Fans are designed for horizontal mounting on a flat roof directly above an air duct or a ventilation shaft.
• In order to avoid ingress of water and snow into the ventilation duct, it is possible to install a fan on the mounting frame.
• The fan is connected to the ventilation duct by means of a counter flange, which is attached directly to the fan base.
• The fan base has holes for fixing bolts that attach the fan to a stationary even surface or to a mounting frame.
• In the VKV 225 EC, VKV/VKH 500 EC, VKV/VKH 630 EC models the counter flange is attached together to the fan inlet ring.
• A mounting frame, a counter flange, and mounting bolts are not included in the delivery set and must be purchased separately.

OPERATION OF FANS WITHOUT A CONNECTED AIR DUCT SYSTEM IS IMPROPER

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.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

• The unit is rated for connection to power mains with the parameters specified in the «Technical specifications» section, according to the wiring diagram.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross-section selection must be based on the maximum load current, and maximum conductor temperature depending on the wire type, insulation, length, and installation method.
• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of the unit. The trip current of the automatic circuit breaker QF must exceed the maximum current consumption of the unit (refer to the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.

The electrical connection is made on the terminal block located in the remote or integrated terminal box of the electric motor. The terminal designations are shown on the label inside the fan casing.
