facility is fitted this should be checked to
ensure that it continues to function correctly,
and the drainage of condensates is not
impaired.
Main Fan Motor
Remove access panel. Dust and other
foreign matter should be cleaned by blowing
over with compressed air and through the
use of a soft bristle brush and cloth. Solvent
wipes may be used to remove heavy soiling
from the motor casing.
Traces of surplus lubricants spreading from
the bearings should also be cleaned away.
Where motors are fitted with grease nipples
bearings should be lubricated with the
correct grade of lubricant. Motors which do
not have grease nipples feature sealed
bearings which are lubricated during
manufacture for their life.
The electrical connections should be
checked as follows.:
The cover to the terminal box should be
removed by undoing the screws which
secure it.
Check connections for signs of corrosion,
tightness, and ensure that there are no stray
strands which could form a short circuit.
Clean, tighten, and replace as necessary.
Replace cover and secure.
Main Fan
Remove dust and other foreign matter by
blowing off with compressed air or through
the use of a soft bristle brush.
Check that the bearings do not show signs
of excessive wear. It should be noted that
these bearings do not require lubricating.
If the bearings require replacing the
following procedure should be followed.
(a) Remove belt(s).
(b) Loosen set screw on eccentric collar and
tap collar in the opposite direction to fan
rotation.
(c) Remove collar and bearing.
(d) Check shaft for alignment and
straightness.
(e) Locate the bearing in its seat and place
on the shaft with the cam facing outwards.
(f) Fit the eccentric collar and engage the
cams.
(g) Tighten initially by rotating, and then by
tapping in the direction of the fan rotation.
(h) Replace fasteners and secure.
(i) Turn by hand to ensure free fan rotation.
Pulleys
Check pulleys for alignment using a straight
edge, if necessary reposition either or both
of the pulleys and the fan motor.
Check for excessive wear within the root
and sides of the grooves, and check for any
other signs of wear or damage, if necessary
replace the pulley as follows.
(a) Release tension on belts and remove.
(b) Release the taper locks by slackening
the securing screws by several complete
turns.
(c) Fully remove one screw from the taper
lock, and having oiled it, insert into the
threaded jacking point.
(d) Tighten screw until the taperlock is free.
(e) Remove taperlock and pulley.
(f) Fit taperlock in new pulley, and
provisionally position on the shaft.
(g) Remove the screw from the jacking
point, and tighten both screws in their
clamping points until the pulley can just be
moved on the shaft by hand.
(h) Align pulleys using a straight edge, and
by gradual alternate tightening of the screws
clamp in position.
(i) Refit belts and check for the correct
amount of tension.
Fan Belts
Check belts for signs of wear.
Frayed or split belts must be replaced using
belts with a common batch code.
Belt tension must be checked, and if on
multi-belt units it is found that one belt
contains more slack than its accompanying
belts, then all the belts on the unit must be
replaced, again using a common batch
code.
