As shown in Figure 15, this can also be accomplished by
pushing the magnet across the gap from the outside with a
pencil or other non-heat conducting material.
On doors where the gap is against an end, top, or
bottom mullion, this process can still be done; how-
ever, the heat will need to be directed between the lip
of the mullion and the edge of the door. It will work
in the same fashion but the back-light shining through
and showing on the mullion will have to be a guide as
to the position of the gasket.
Cool the Gasket
Once the gap is closed, remove the heat and allow the
gasket to cool, undisturbed, for 3 to 5 minutes. As the
gasket cools, it will set permanently in this new shape.
Once the gasket is cool to the touch, open the and close
the door. Verify that the gasket seals. If not, repeat the
process. If the gasket rolls it must be replaced.
Use a soft cloth or paper towels, and a mild soap and
water solution to thoroughly clean the gasket. Dry the
gasket completely with a fresh cloth or paper towels
before closing the door on a clean door frame.
DOOR HANDLE REPLACEMENT
Carefully pull the
magnetic gasket out of
the groove nearest the
handle to expose the
mounting screws as shown
in Figure 16. Remove the
screws and replace the
handle. After reinstalling
screws, carefully push
gasket back into groove.
If needed, use a mild
soap and water solution
to lubricate the gasket.
Clean and dry the gasket
to complete the door han-
dle replacement.
FRAME HEATER REPLACEMENT
Always turn off power to the case before working on
any electrical components. The old wireway covers
must be removed to access the door frame heaters.
Begin by inserting a putty knife into the groove
between the wireway cover and fiberglass frame, about
an inch (25 mm) away from joints in the frame as
shown in Figure 17(A). Carefully begin to pry off the
cover.
As shown in Figure 17(B), use a second putty knife
or flat head screwdriver to hold up the cover. Pry the
remainder of the section up, using putty knife only,
until the entire cover is off and the frame heater inside
the door frame is exposed.
