MOUNTING AND SETUP
The fans must be mounted vertically. While installing the unit ensure convenient access for subsequent maintenance and repair. The fan
must be mounted on a plane wall.
CAUTION! When installing outdoors, it is necessary to install a canopy above the fan to protect it against atmospheric influences.
Set the circuit breaker to OFF. Unscrew self-tapping screws and remove the cover.

Attach the fan to the installation site. Mark the mounting holes.
Drill the holes and insert the dowels. Secure the fan by routing the power cable through the cable
gland.
CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS.
THE UNIT MUST BE CONNECTED TO POWER MAINS BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE SHOWN
ON THE RATING PLATE.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
The fan is rated for connection to single-phase AC 220-230 V/50 (60) Hz power mains. For electric installations use insulated durable heat-
resistant wires with the minimum wire cross section 1 mm2.
The actual conductor cross-section selection must be based on its type, the maximum permissible heating, 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 circuit in the event of overload or short-circuit.
The circuit breaker location must ensure free access for quick shutdown of the fan.
Connect the fan to the terminals located inside the fan casing in compliance with the fan wiring diagram and the terminal designation.
The terminal designations are shown on the sticker inside the fan casing.

TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS!
Maintenance means regular cleaning of the fan surfaces from dust and dirt. Use a soft dry brush or a vacuum cleaner to remove dust.
The blades require thorough cleaning once in 6 months.
The filter prevents the fan soiling and reduces the cleaning periodicity. To clean the fan undo the self-tapping screws and remove the
fan cover. Clean the impeller blades with a cloth wetted in water and mild detergent solution. Avoid liquid dripping on the motor! After
cleaning the impeller, install the cover back and tighten the screws.
STORAGE AND TRANSPORTATION REGULATIONS
