6. OPERATION
Before starting, check the followings; Be sure that foreign objects are removed from fan area and connected
duct system, check connection to the electrical installation, minimum air gap between the tip of the blade and
the housing and no noise appears when starting the fan. If the air gap is correct, switch the device on and off
briefly, in order to check the direction of rotation of the fan. The rotation direction of the fan must match up
with the direction of the arrow on the housing of the fan. If the direction of rotation is wrong, interchange two
phases in order to set the correct direction of rotation. Connection flanges are made with bolts for lightning
protection. If gasket is used, sufficient duct connection should be bridged to the duct connection.
7. HANDLING & STORAGE
The fans are delivered on wooden pallets wrapped in plastic stretch. Transport the fan to the place of
assembly in its original packaging. During transport, connection cables, terminal box and wire connections
mustn’t be damaged. Load and unload the fan carefully, in order to avoid possible damage. Use suitable
lifting equipment. The fan should be stored in a safe, clean, dry, vibration free, location. A regular monthly
rapid spin of the impeller is recommended to prevent grease hardening and possible brinelling of the
bearings; the impeller should not be in the same angular position after rotation.
When dismantling the crate to gain access to the fan assembly care should be taken to avoid injury from
sharp edges, nails, staples, splinters, etc.
ALWAYS WEAR APPROPRIATE PROTECTIVE CLOTHING (INCLUDING HARD
HATS, EYE PROTECTORS A
ND EAR DEFENDERS) WHEN WORKİNG IN THE
