Front and Rear Panels

Removal of Front Panels and Access to Component Panels

Always use caution when removing any of the front panels as live contacts are inside at 24VAC
as well as the line voltage. It is highly recommended to turn off power to the unit at the circuit breaker or
unplug the unit before removing any of the front panels.

The first step to removing any of the front panels is to remove the grease drawer(s). Always
check the grease level in the drawer by slowly pulling the drawer forward. If the Unit has been in
operation recently this grease may be hot. Set aside.

The two lower front panels will be next.
There are two types of lower front panels: those
next to the cabinet wall and those next to a
grease drawer enclosure. Both types require
the removal of two phillips head screws next to
the controller panel. Once the screws are
removed the panels may spring forward on the
controller panel side. The lower front panel next
to a grease drawer enclosure is removed by
pulling the controller panel side toward you then
moved toward the grease drawer to remove it’s
tab from a slot in the grease drawer enclosure.
Set aside.

2

The lower front panel next to the
cabinet wall is very similar except the tab / slot
is reversed. After removing the two retaining screws at the controller panel, pull the lower front panel
toward you, then move it towards the controller panel. This removes a tab attached to the cabinet wall
from a slot in the lower front panel. Set aside.
