Removing the Series F4P Controller
The controller can be removed most easily by disengaging
the mounting bracket hooks and pushing the controller
forward through the panel. Be ready to support it as it
slides forward through the panel.
Tools required: one #2 Phillips screwdriver, one flat-head
screwdriver and some means of supporting the controller
as it slides out the front of the panel.
1. Remove all the wiring connectors from the back of
the controller. Using the Phillips screwdriver,
unscrew the four screws on the mounting bracket
(two on top, two on bottom) until the tips are
completely retracted into the shafts.
2. Slide the tip of a flat screwdriver between the case
and the center top side of the mounting bracket.
Rotate the screwdriver 90 degrees, stretching the
bracket away from the case so the hooks on the
bracket disengage from the slots on the case. Hold
the bracket and press the controller forward slightly
to prevent the disengaged hooks from snapping back
into the slots.
3. Repeat this operation to disengage the hooks on the
bottom side of the mounting bracket.
4. Press with one or two fingers on the lower half of the
back of the unit so that the controller slides forward
through the panel. Hold the bracket steady; do not
pull back. Be ready to support the controller as it
comes through the front panel. Remove the mounting
brackets and retention collar from the back side of
the panel.
