B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws (bearing setscrews), grounding connections, and nonpermanent gas connections
(unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed
belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and
valves. Complete operational check of ALL safety devices (door switch, lint drawer switch, sail switch, burner,
and hi-limit thermostats).
30 DAYS AFTER INSTALLATION
SHUT OFF ALL POWER TO THE DRYER. Verify that the electrical connections to the motor contactors
and overloads are tight. This is done to accommodate the compression of the wires over time.
C. LUBRICATION
MONTHLY
The two (2) bearings that support the impellor/fan shaft must be lubricated. Use Shell Alvania #2 grease or its
equivalent. Generically, this grease would be described as an NLGI Grade 2 multipurpose industrial grease with
a lithium thickener and mineral base oil.
EVERY 3 MONTHS
The four (4) bearings that support the drive and idler shafts must be lubricated. Use Shell Alvania #2 grease or
its equivalent. Generically, this grease would be described as an NLGI Grade 2 multipurpose industrial grease
with a lithium thickener and mineral base oil.
D. BASKET (TUMBLER)
The basket (tumbler) is made of 14-gauge stainless steel perforated panels, four (4) stainless steel ribs, and two
(2) outer basket (tumbler) rings made of rolled steel iron. The basket (tumbler) is a completely welded assembly
so the perforated panels are not removable.
E. AIR BLOWER DRIVE SYSTEM
The impellor (fan) used in the dryer is an 18-1/2” (47 cm) diameter squirrel cage impellor (fan) wheel. It spins
in a counterclockwise (CCW) direction looking at the back of the blower housing.
The impellor (fan) shaft is mounted in two (2) pillow block bearings, and the shaft is driven by two (2) B-section
V-belts connected to the blower motor.
The blower motor is mounted on an adjustable base. The motor position can be easily adjusted so that proper
tension can be maintained on the V-belts.
