• The power supply line for the fan
requires a multi-pole circuit breaker
/ isolation switch with a minimum
contact break gap of 3 mm (ref. PN-EN
60335-1)!
• The mains system, voltage and
frequency must match the nameplate
ratings of the fan.
Dimensions
The dimensions of specific fan models
are shown on page 2.
MAINTENANCE AND CLEANING
Servicing and maintenance
• Use protective footwear and gloves
during maintenance!
• During all maintenance and ser-
vicing 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 for-
eign 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 unpro-
fessional repairs.
• For equipment where engines with
ball bearings have been used with
“lifetime lubrication”, the engine does
not require lubrication.
Cleaning
Electrocution hazard by damaged wiring
insulation!
Before attempting to clean the fan,
isolate it from the mains voltage with
the circuit breaker.
Secure the circuit breaker against
inadvertent operation!
• Clean the visible parts of the housing
with a damp cloth.
• Do not use aggressive paint solvents!
• Do not clean with a high pressure
cleaner or strong jets of water!
• Clean carefully to prevent water from
entering the motor or the terminal box.
• Always keep the guard grille at the
suction side clean.
