START-UP
Check List
Make a walkway inside unit components to protect insulation. Re-
move all construction debris from unit interior. Remove walkway
before starting unit.
FILTERS
Install unit filters in all filter sections.
FANS
1. Check lubrication of fan, motor bearings, and linkages.
a. Note that bearings are shipped completely full of grease
for corrosion protection and may run warm temporarily
on start-up until excess grease has discharged.
b. Hand-operate all linkages, such as damper and guide
vanes, to check for freedom of movement.
2. Check tightness of bearing setscrews or locking collars
(Fig.
63). Also, check tightness of setscrews on fan wheels
and sheaves.
3. Check tightness of fan shaft bearing mounting.
4. Recheck sheave alignment and belt tension. (Refer to Fig. 40
and 41.)
5. Hand turn fan to make certain fan wheel does not rub in
housing.
6. Check fan speed with a strobe-type tachometer or use the fol-
lowing formula: Obtain the motor rpm from the fan motor
nameplate and read sheave pitch diameters marked on the fan
and motor pulleys, or estimate the pitch diameters by using
the pulley outside diameters.
