for mounting and maintenance after careful study of the present
user's manual.
The single-phase power mains must comply with the acting local electrical
norms and standards.
The fixed electrical wiring must be equipped with an automatic circuit
breaker.
The fan must be connected to power mains through an automatic circuit
breaker QF integrated into the fixed wiring system with the gap between
the breaker contacts on all poles not less than 3 mm.
Check the fan for any visible damages of the impeller and the casing before
starting installation. The casing internals must be free of any foreign objects
which can damage the impeller blades.

differ from those ones described herein.
Follow the user's manual requirements to ensure durable
and trouble-free operation of the fan.
While mounting the fan do not compress the casing!
Deformation of the casing may result in the motor jam and noisy operation.
Misuse of the fan and any unauthorised modifications are not allowed.
Take steps to prevent ingress of smoke, carbon monoxide and other
combustion products into the room through open chimney flues or other
fire-protection devices. Sufficient air supply must be provided for proper
combustion and exhaust of gases through the chimney of fuel burning
equipment to prevent back drafting.
