PROBLEM CAUSE POSSIBLE
SOLUTION
GLASS ISN’T
DRYING OR
SMALL WATER
SPOTS ARE
PRESENT
Blower tube (air knife) slot is plugged
Blower filter plugged
Blower tube slot out of adjustment
Blower piping leaking or plugged
Blower runs backwards
Blower tubes are too far away from
glass
Misalignment (top to bottom) of blower
tube sections
Rinse water is too cold
Clean blower tube slot (see
Maintenance
)
Replace or clean filter
Open the slot to 0.032 to 0.045 inch width
(consult factory) – Check the blower motor
for over-amperage
Correct by replacing the tube or unplugging –
Piping must be straight and of correct length
Reverse any two blower leads in the control
panel
Adjust to
⅛
to ¼ inch from glass (top and
bottom)
Top and bottom blower tube slots should be
adjacent to each other – The bottom tube
should be closer to the infeed of the Washer
so the top trailing edge is blown off last
Use a mix of heated water and cold water is
available (110
ºF is ideal)
GLASS SHOWS
ROLL MARKS
Dirty work area
Clean rolls with hot, soapy water and rinse
thoroughly
Continuous running may eliminate this
problem, as all of the rolls may collect some
lint, rubber or plasticizer overnight – Keeping
the washer exit area covered when not in use
will help keep it clean
Drying area of the Washer has too much
airborne particles – Clean the work area
Daily startup using insulated glass may
require flipping the pieces over and running
through a second time as the topside will be
cleaner than the side contacting the rolls –
after one to two hours this may not be
necessary, however, it may be desirable for a
consistently higher quality yield
