MAINTENANCE AND CLEANING
Servicing and maintenance
• Use protective footwear and gloves
during maintenance!
• During all maintenance and servicing
works the electrical and OHS
regulations (PN-IEC 60364-3) must be
observed.
• Before servicing the fan, isolate it
from the mains voltage with the circuit
breaker. Secure the circuit breaker
against inadvertent operation!
• The fan ductwork must be clear of
foreign bodies: hazard of injury by
objects blown out at a high speed!
• Do not attempt any maintenance when
the fan is running or at live voltage!
• If excessive vibrations are felt or
heard, have the technical inspection
carried out by a qualified electrician.
• The maintenance intervals depend
on the actual contamination of the fan
rotor and must not be longer than 6
months!
• Check the fan rotor for cracks. The
manufacturer shall not be liable for any
damage resulting from unprofessional
repairs.
• For equipment where engines with ball
bearings have been used with “lifetime
lubrication”, the engine does not require
lubrication.
Cleaning

role in contributing to reuse and
recovery, including recycling, of used
up appliances, and it is the stage where
attitudes are created that impact the
preservation of the common being the
clean natural environment. Households
