Guarding
NOTICE
The fan must be guarded according to local regulations
Illustration16: Optionally available guard
Default, the fan is delivered with a guard on the intake side. The shutter acts
as a guard for the exhaust side, but does not provide the required safety
distances to prevent hazard zones being reached by upper and lower limbs
(ISO 13857:2008). Depending on installation height or location, the shutter
may therefore not provide the required level of protection. A guard for in
between the shutter and fan housing is optionally available. Please contact
your supplier for more information.
Condensate drain holes
The fan motor has drain holes to allow condensation that may form inside the
motor to leave the motor. After installation, the drain hole at the lowest point
of the motor must be open, the other drain holes must be closed.

6.2.1 Thermal protection
1~ fan motor thermal protection
Thermal protectors are built-in standard in 1~ fan motors. Thermal protectors
are of the thermostat type TB: thermostat opening on increase of
temperature.
In 1~ fan motors, the thermostat (TB) is by default wired in series with the
phase (L) of the supply. The motor is as such self-resetting: when the motor
overheats, the thermostat will switch off the motor automatically and once the
motor has cooled down, the motor will start automatically again.
The presence of the text “Thermally Protected” on the rating plate and/or
datasheet indicates that thermal protection is built-in the 1~ fan motor and that
it is wired in series with the phase (L) of the supply.
WARNING
If the unexpected start of the motor by the thermostat can
cause a hazard or is prohibited by local regulations, the ther-
mostat must be connected into a control circuit that will not al-
low the motor to restart until the circuit is manually reset.
3~ fan motor thermal detection (optionally available)
Thermal detectors are optionally available in 3~ fan motors. Thermal
detectors are of the thermostat type TB: thermostat opening on increase of
temperature.
In 3~ fan motors, the thermostats (TB) are by default wired to separate
terminals on the terminal block. An external control circuit can be connected
here. NOTICE! The thermostats in 3~ fan motors cannot be
wired in series with the power supply.
Maximum load for the thermostat (TB)
VAC: maximum 500 V
IAC: maximum 1.6 A
Cos Φ: minimum 0.6
Maximum number of switching cycles: 1000
VDC: maximum 12 V
IDC: maximum 40 A
Maximum number of switching cycles: 1000
6.2.2 Speed control
Verify that this fan is suitable for speed control. On the datasheet and rating
plate the following (combination of) codes can be found:
FC = suitable for frequency control / VFD (Variable Frequency Drive)
E = suitable for electronic voltage control (TRIAC / phase cutting)
T = suitable for transformer voltage control
WARNING
If none of these codes is listed, this fan cannot be speed con-
trolled!
Variable Frequency Drive (FC / frequency control)
• Do not reduce the frequency to less than 20% of the nominal frequency
as listed on the rating plate.
• When using a variable frequency drive, the wiring instructions of the vari-
able frequency drive manufacturer must be followed.
WARNING
Do not increase the frequency beyond the nominal value as lis-
ted on the rating plate
Electronic Voltage Control (TRIAC / SOLID-STATE / phase
cutting)
• Do not reduce the voltage to less than 40% of the nominal voltage as lis-
ted on the rating plate.
• Motor noise (humming) can occur due to this type of control
Transformer voltage control
• Do not reduce the voltage to less than 40% of the nominal voltage as lis-
ted on the rating plate.

ply and is activated, the fan motor will automatically re-start
after cooling down.
Risk of injury due to unexpected start.
CAUTION
The fan motor can get hot during operation
Do not touch it to prevent burns
Infrequent use
If the fan is used less frequently than once per month, run the fan each month
at least 2 hours at full speed to avoid buildup of moisture in the fan motor and
to keep the bearing lubricant in good condition.
9 Maintenance
DANGER
Switch off and completely isolate the fan from the electrical
supply before commencing maintenance.
WARNING
All moving parts must be at a complete standstill before com-
mencing maintenance.
WARNING
Even when electrically isolated, fans may be subjected to free
spinning or „wind milling“. Secure the impeller physically to re-
strict rotational movemenent where this poses a risk.
• All safety and work regulations have to comply to the current standards.
• All work has to be carried out by qualified personnel.
• When you remove safety devices such as guards for maintenance, you
must install these safety devices after maintenance.
9.1 Maintenance schedule
►Maintenance tasks – TO BE CARRIED OUT EVERY MONTH
1. Examine the fan housing for defects and remove any dirt that has accu-
mulated.
2. Examine the motor and remove any dirt that has accumulated on the
motor and between the motor cooling fins.
3. Examine the impeller for defects and remove any dirt that has accumu-
lated.
4. Examine the condition of the guards (if fitted) and remove any dirt that
has accumulated.
5. Examine the shutter for defects and remove any dirt that has accumu-
lated.
►Maintenance tasks – TO BE CARRIED OUT EVERY 3 MONTHS
1. Check the condition of the bearings.
2. Check the tightness of fasteners and fixings.
►Maintenance tasks – TO BE CARRIED OUT ANNUALLY
1. Only for 1~ fan motors: check the capacitor capacitance.
9.2 Maintenance subjects
Cleaning
In areas of application where high levels of contamination are present,
cleaning intervals should be adjusted accordingly.
Cleaning is preferably done using a soft brush. Do not use any aggressive
detergents, solvents or chemicals for cleaning.
Wet cleaning
Wet cleaning is allowed using low pressure clean water spray. Avoid directing
water jets at bearings and electrical connections as much as possible.
When wet cleaning is planned, close any open condensate drain holes before
commencing wet cleaning.
WARNING
Do not use a high pressure cleaner.
Water may penetrate electrical connections and bearings.
►After wet cleaning
1. Open the condensate drain hole at the lowest point of the fan motor.
2. Run the fan for 2 hours at full speed to remove any moisture that may
have entered the fan motor.
Bearings
The bearings used in the fan and/or fan motor are maintenance free and
greased for life. Average lifespan during normal operation is >30.000 hours.
Defects in the bearings can usually be detected by listening. When the shaft /
impeller is rotated by hand, it should move freely with a smooth uniform
sound. Squeaking or grinding noises indicate the bearings may require
replacement.
Impeller
Cleaning the impeller is very important. A dirty impeller will suffer from
imbalance resulting in vibrations. A dirty impeller will also result in reduced fan
performance and reduced fan efficiency.
V-belt tension check
►Simple method to check proper V-belt tension
1. Measure span length A
2. Calculate deflection length C
ðC = 0.0156 x A (mm)
ðPushing with deflection force B, deflection should be C
Deflection force B:
V-belt profile: A Deflection force B (kg)

position of the motor.
Illustration24:
1. Loosen the bolts (1)
2. Tighten the bolts (2) until the required V-belt tension has been reached
3. Fasten the bolts (1) again
Capacitor (1~ fan motor)
Capacitor capacitance decreases slowly over time. Average lifespan is ±
30.000 hours. Replace the capacitor when the capacitance has dropped
below the value as listed on the capacitor.
Start capacitor (1~ fan motor)
The start capacitors’ lifespan is 500.000 starts. Replace the start capacitor
when the number of starts has reached 500.000.
The start capacitor cannot be serviced or repaired. The start capacitor must
be replaced if it is not functioning properly anymore.
Louvre shutter
Cleaning the shutter is very important. A dirty shutter will reduce the amount
of air moved by the fan reducing your fan efficiency. Clean the louvres
carefully to avoid bending or damaging them. Damaged louvres can cause
the shutter to leak.
