NB! Always break current before working with the fan.
• Before service, maintenance or repair begins, the fan
must be tension free and the impeller must have
stopped.
• When cleaning and maintaining the fan always have
to be secured when open, so it can’t fall down and
cause bodily injury.
• The fan must be cleaned when needed, but at least
once per year to maintain the capacity and to avoid
unbalance which may cause unnecessary damages
on the bearings.
• No special tools needed when cleaning.
Loosen the screws in the front (
A:
TKV/TKH 560 B-960,
B:
TKV/TKH 300-560 A) , open the fan and secure so
it can’t fall down.
At maintenance, dismantle the roof of the fan to expo-
sure the motor and impeller (
C
).
Attention, look out for sharp edges and corners.
• The fan bearings are maintenance-free and should
be renewed only when necessary.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used.
Cleaning should be done without dislodging or
damaging the impeller
.
• The capacitor in the single-phase fans has finite life-
time and should be exchanged after 45.000 hours of
operation (about 5 years) to secure maximum func-
tion. Defective capacitor can cause damage.
• Notice the weight of the fan when closing after
inspection/cleaning.
• Mount back all details in reverse order. Check that
the fan is closed and locked before starting.
• Make sure that there is no noise from the fan.
NB! Single-phase fans are provided with automatic
thermo-protector that disconnect if motor temperatu-
re gets to high. Resetting will be done automatically
when motor is cold.

The fan must be transported in its packing until instal-
lation. This prevents transport damages, scratches and
the fan from getting dirty.
TKV/TKH 660-960 have four lifting holes (Ø 20
mm) on every side to fasten e.g. lifting eye bolts. See
Technical data on page 26 for the weight on every fan
size.
