Roof fans SMART-SN
13 of 15
OPERATIONAL USE
The
SMART-SN
fans design enables the device to work without constant operation in continuous operation.
To start the fan, use (see above – Table 6):
RS
type motor starter,
WS
type motor breaker,
FA/3
inverter.
The choice of how to start SMART-SN fans depends on many factors, such as the power of the
electric motor, nature of the motor frequency control, type of motor overload protection, etc.
Incorrect use does not take into account the manufacturer's disclaimers (see item 3 "MANUFACTURER'S
DISCLAIMER") and is considered improper (see item 2 “APPLICATION”). Improper use may cause damage to
the motor bearings, loss of balance of rotating elements, the appearance of excessive vibrations, impeller
deformation, damage caused by friction, and ultimately destruction of the fan.
TROUBLESHOOTING GUIDE
If you notice any signs of device malfunction (e.g. increase in noise, vibration, reduced performance),
disconnect the fan from the power supply and check for the cause of the interference. Common disorders and
their causes are presented below – see – Table 8.
Table 8 Typical disturbances and remedies
Disturbances
Possible causes
Remedies
no possibility to start the fan
failure of one phase or too
low voltage or blocked impeller or
damaged motor
supply voltage, check electrical
protection, remove impeller blocking
object, replace motor with new one
the appearance of vibration
and vibration of the fan
object obstructing the fan
disconnect the fan from the power
supply, remove the engine cover and
remove the object
rotor damage
replace the impeller with a new one
poor efficiency
wrong rotor rotation direction
change the impeller rotation direction
by changing the phase order
loud fan operation
destruction of engine bearings
replace the engine with a new one
distortion of impeller inlet parts
and friction
replace deformed elements
MAINTENANCE AND RECYCLING INSTRUCTIONS
Maintenance
The design of the fan enables continuous operation, provided that it is used correctly and periodic inspections
and maintenance are carried out.
The user carries out checks and general maintenance on his own!
At least every
12 months
, check the technical condition of the fan and the motor following the principles of
operating electric drive devices.
Inspections of the fan may be performed by a qualified person with appropriate qualifications and only after
disconnecting the device from the power supply. To disconnect the fan from the main circuit, a
service switch
is
used, the purchase, installation, and placement of which is the responsibility of the fan user.
Service switches
from
KLIMAWENT S.A.
offer as optional equipment - see above, Table 6.
As part of the fan check, check the following. If necessary, remove the fan from the roof base:
A.
Check the correctness and accuracy of tightening the mechanical and electrical connections.
B.
Check the condition of the impeller and the inside of the fan and detect and remove accumulated dirt
or foreign bodies.
C.
Check the alignment of the impeller relative to the inlet fitting (equal distance over the entire
circumference between the impeller inlet and the fan inlet fitting).
D.
In case of vibration or noise during fan operation, measure the vibration and checking that there is no
contact between the rotating impeller components and the inlet sleeve or other housing components.
