Tasks that can only be performed during operation whilst
observing the applicable safety regulations and accident
prevention regulations (e.g. checking smooth running) are
excepted from this rule.
DANGER OF INJURY FROM ROTATING PARTS!
Before performing any work on fans:
If the fan has a repair switch, switch off the drive motor
by moving the switch to the “0” position. If the fan has a
terminal box, the power supply must be switched off via the
control unit and secured against reactivation before dis-
connecting the connecting cable of the drive motor. Subse-
quently, disconnect the motor wiring in the terminal box and
insulate the cable ends.
Only begin maintenance or repair tasks once the fan impeller
has come to a standstill and the motor has cooled.
DANGER OF INJURY FROM FLYING PARTS!
Before conducting maintenance tasks, remove harmful or
hazardous residue from the conveyed medium present in the
fan using appropriate measures.
Safety and hazard warnings during maintenance, repair and
cleaning tasks
Be aware of all rotating parts during cleaning,
maintenance and repair tasks. TANGLING HAZ-
ARD! Wear close-fitting clothing in the danger
zone.
Be aware of the danger of crushing during clean-
ing, maintenance and repair tasks.
Be aware of the danger from electrical current
when performing cleaning, maintenance and
repair tasks.
Cleaning, maintenance and repair tasks must
only be conducted in non-explosive atmospheres.
For reasons of safety, only tools made from
non-sparking materials must be used when per-
forming tasks of this kind.
Be aware of contaminated components during
cleaning, maintenance and repair tasks.
7.1 Standstill
Standstill or temporary storage of the fan must be avoided.
If this is not avoidable in certain cases, the fan must be run
for at least two hours every two months. This is important to
prevent the motor bearings from sustaining damage caused
by prolonged standstill.
7.2 Sporadic fan operation
If the radial fan is not employed in continuous operation but
only sporadically, it must be run for at least two hours every
two months. This is important to prevent the motor bearings
from sustaining damage caused by prolonged standstill.
7.3 Continuous fan operation
Annual routine inspections must take place if the fan is used
in continuous operation:
Check operational readiness:
•
Check plastic parts, e.g. for wear, damage, contamination
and water-tightness. If wear, damage or leaks are found,
shut down the fan for reasons of operational safety and
contact the supplier. If contamination is found, shut down
and clean the fan.
•
Free passage of air vents and condensate outlets.
•
Check that bolted connections are tight.
•
Check that the fan does not vibrate when running (if the
fan vibrates, see chapter 7.7 “Malfunctions”).
•
Check that the identification plate is legible and request a
new one if necessary.
•
Check the accessories.
Check the electrical connections:
•
Check electrical wires and connecting terminals for corro-
sion and clean if necessary.
•
Check the power consumption (if motor problems occur,
see chapter 7.7 “Malfunctions”).
Wear personal protective equipment (PPE)! Individual com-
ponents may be contaminated depending on their area of
application.
The warranty is rendered invalid if damage occurs due to a
failure to conduct the regularly required inspections.
