Air Tank
(optional) With air pressure still on the furnace
system, remove the door panel below and
to the left of the flowmeters. Open the
small valve for the air compressor reservoir
drain. Purge the tank until the condensate
has been removed. Monthly or
as required.
Battery, PLC The Opto22 LCM4 controller has a lithium backup battery with a 5-year life
cycle, but other factors may affect its service time. Storing the unit with the
furnace power off shortens the battery lifespan. The battery will actively
back up RAM when the Furnace is OFF. When the battery is near the end of
its useful life the BATT LED will turn red. Once the battery begins to fail, the
furnace controller will often fail to retain program parameters after power is
lost to the controller. Eventually the program may not reset or may fail to
load. BATT LED is normally green.

Belt Shaft
Bearings-
perm To gain access to the belt shaft bearings remove the end covers from both
ends of the machine. Located at both ends of each belt shaft are
permanently-lubricated bearings. These bearings should not be lubricated. None
Belt Shaft
Bearings
with grease
fittings Bearings with grease fittings should be lubricated with a general
multipurpose bearing grease. Apply enough grease to the bearing block so
that excess grease can be visually seen squirting out along the shaft of the
device. Wipe off all excess grease that has squirted out to avoid dirt
accumulation. 6 months
Belt Shaft
Rollers The belt shaft rollers should be
inspected periodically to make sure
that they are centered on their
respective shafts. Remove the end
covers to gain full access to the belt
shaft rollers. If a roller is misaligned,
loosen the setscrews that hold the
roller onto the shaft and use a rubber
mallet to move the roller on its shaft.
Use a scale to make sure the rollers
are centered to within 0.125 inches
on the belt shaft.

Belt
Tracking
Adjustment The belt should be checked periodically to make sure that it is tracking
through the center of the oven. Belt tracking can be checked visually at the
entrance and exit ends of the oven. The belt should be centered between
the belt guides at the entrance and exit ends of the oven. If the belt tracks
off-center this problem can be rectified by
realigning the belt shafts. First, set the
belt speed to zero and remove the end
covers at the entrance and exit end of
the machine to expose the frame ends
and the belt shaft bearing mounts at the
end of the belt shafts. The following
procedure can be used to correct
tracking problems at either end of the
furnace. Weekly
