Facade removal
The facade is removed by loosening the top left and right Phillips screws
on the back of the facade to allow the securing clips to rotate away from
the side panels. The facade can simply pull off of the front by pulling it
out of the bayonet mounts that secure it to the upper left and right panels.
If the facade will be completely removed, the electrical plugs should be
disconnected. The ground wire should be removed from the top right
grounding screw on the cabinet box, not from the facade (Fig. 80.1).
Evaporator cover removal and reinstallation
• To avoid equipment damage, do not remove evaporator cover until freezer
temperature is >10 C (>50 F).
To avoid damaging the cover, you must allow sufficient time for the unit
to defrost prior to removing the cover. You can put unit through a manual
defrost to speed the process (see Test defrost/manual defrost section).
1. Cut silicon sealant on back of evaporator cover to allow removal
(Fig. 81.1).
2. Using a 1/4" socket with an extension of at least 11" , remove the 5
sheet metal screws on each side of the evaporator cover (Fig. 81.2).
3. Carefully pull permagum away from evaporator cover where refrigerant
lines enter through cover.
4. Gently lift the cover straight up and off of the module and evaporator
(Fig. 81.3).
5. Prior to reinstalling the evaporator cover, remove all of the old silicon
sealant from the back of the evaporator cover and base (Fig. 81.4).
6. After installing evaporator cover and screws, apply a bead of silicon
sealant to back seam of evaporator cover and base (Fig. 81.5).
7.
Re-adhere permagum around utility penetration opening on evaporator
cover.
