ELECTRIC SINGLE SLIDERS

Operaon and Maintenance Procedures

Operation Procedures:

 Unlock all locking mechanisms and ensure

that the doors are free of obstructions.

 Turn the power Switch to the “on” position,

located on the upper left hand corner.
(Some windows the switch may be located
behind the access cover.)

 Proper operation of the “Up-Eye” unit re-

quires the attendant to be directly in front

of and over all 3 photoelectric sensors

while serving. Proper operation of the
“Thru-Beam” unit requires the attendant to
stand between the Emitter and Receiver
eyes.

Remove access cover panel to service electrical and

mechanical components

General Maintenance:

 Always disconnect the power supply before

servicing.

 Slide rail system should be kept clean and

re-oiled with light weight oil every six (6)
months.

 <Note> The outside edge of the photo-bar

should be lined up with the inside edge of
the locking jamb.

General Cleaning Guidelines:

 All weather-stripping should be checked

and cleaned weekly.

 All glass, aluminum framing, stainless

steel, and plastic eye covers & lens should
be kept clean at all times. All cleaning flu-

ids and applicators should be non­abrasive.

 The eye-sets should be checked weekly to

make sure they are fully fastened to unit or
wall. They should also be cleaned of any
dirt or debris daily with non-abrasive clean­er.

Please refer to the trouble shooting section for

additional information on the window adjust­ments or service procedures.
