VI. a - REHINGING THE DOOR:
The door(s) on all UHT, ULT & UPT models can be eas-
ily rehinged in the field. To begin, open the door to its
maximum position. Support the non-hinged end of
the door so minimum movement occurs when the bolts
from the lower hinge plate are removed. Remove the
lower hinge plate and then the door from the top hinge
bracket. The hinge plate pin and plastic bushing will
remain in the top hinge plate (see figure 14).

Top Hinge Assembly
Lay the door down on a padded flat surface while be-
ing careful not to allow the lower hinge plate and
mechanism stem to slide out the bottom of the door.
NOTE: The lower hinge plate is under spring tension
(see figure 15). Grasp the lower hinge plate. While
keeping a firm grip on the plate, carefully slide it out
the bottom of the door just far enough to allow the
plate to rotate a full 360°. Unwind the tension of the
spring by carefully allowing the hinge plate to rotate a
full 360° several times.

Bushing
Slide the hinge plate and hinge mechanism stem out
the bottom of the door.
NOTE: Remove the brass bushing from the bottom of
the door only if spring replacement is necessary. Both
the spring and bushing will need to be new parts.
NOTE: When installing, make sure the lower hinge
plate and hinge mechanism stem are rotated no more
than six (6) full turns while applying tension to the
spring.

VI. a - REHINGING THE DOOR (cont'd):
To reinstall the door, position the lower hinge plate
into the position of being open 90° to the cabinet.
Place the top hinge plate pin in the hole in the top of
the door and support the other end of the door for
minimal movement.
Start the bolts in the lower hinge plate and tighten the
bolts enough to hold the door in place. Remove the
block from under the end of the door. Adjust the door
as outlined in section VI. c.
VI. b - PREPARING FOR EXTENDED SHUT DOWN:
If the refrigerator is not to be used for an extended
period of time, disconnect the electrical power
supply and open the doors. As soon as the cabinet
has warmed up to room temperature, wipe out the
interior. Leave the doors open and check again to
make sure that no moisture has collected on any
parts. To restart refrigerator, follow instructions
under PRESTART CHECKS and OPERATION.
VI. c - ADJUSTING THE DOOR:
Occasionally the door(s) may require alignment
adjustment. To do so, first open the door and
loosen the hinge plate screws enough to move the
hinges if desired, but the door is held in place.
Center the door in the opening. Next level the top
hinge plate and tighten the screws. Finally, level
the lower hinge plate and tighten the screws (see
figure 16).

VI. d - DOOR GASKET(S) REPLACEMENT:
Remove the old gasket by pulling it out from the
gasket retainer. Next, install the four corners of the
new gasket by pushing straight in on the gasket
until it is hooked behind the gasket retainer. Be
careful not to stretch the gasket as it will not return
to its original length. Starting at the center of one
edge, push the door gasket straight in until it is
hooked behind the gasket retainer.
from this point out to the corners, continue pushing
the door gasket straight into the gasket retainer.
proceed doing the same to each of the remaining
edges until the gasket is completely installed.
