SECTION 5
Cleaning Action Quality
The quality of the cleaning action depends primarily
on these factors:
No detergent or too much detergent
Conveyor speed
Brush adjustment
Cleanliness of the Washer and the water
Proper detergent solution flow to the brushes
Proper rinse water flow to the brushes
The operator can vary the cleaning action of the
Washer by increasing brush pressure on the glass,
changing the conveyor speed, changing the detergent
concentration or changing the temperature of the
detergent solution. The Washer should have
approximately a ¾ inch of contact with the glass
surface on each brush.
To make a brush adjustment, loosen the stop nuts at
both ends of the brush. Turn the adjusting nut to
raise or lower the brush. Retighten the stop nuts
when completed.

The slower the conveyor speed is, the longer the
brushes can scrub the glass. It is better to slow the
conveyors rather than to increase the amount of
detergent or raise the water temperature.
TEMPERATURE CONTROLLER
On Washers equipped with the detergent option, the
temperature of the detergent solution is regulated by
a temperature controller. This is located on the
operator control panel and displays the detergent
solution temperature whenever the electrical power to
the machine is on.
To heat the detergent solution to the setpoint
temperature, the “
DETERGENT HEATER
”
pushbutton must be on. Normal temperature control
variation is
±4ºF. when he Washer is running. If
the pumps and conveyors are off, the control is
much closer.
Setpoint Adjustment
The controller setpoint is adjusted to 130
ºF
at the
factory. To change the temperature controller
setpoint:
