FIELD REPLACEMENT:

WALK-IN DOOR HINGES

The hinges on Bally Walk-in doors are designed for many years of trouble-free service. These spring-loaded, self-closing

hinges will operate smoothly if the door has been installed according to the Bally Walk-In Installation Manual.

Pre-Checks:

Our experience has indicated the hinges are often
replaced needlessly due to erroneous diagnosis. If a
walk-in door fails to close automatically, make the
following installation checks before replacing the
hinges:

1. Make sure the door does not drag during any part
of its movement. Any catching of the door must be
corrected.

The door panel must be level and plumb for the

door to operate properly.

2. Check the wiper gasket to make sure there is no
excessive drag on the step plate. The wiper gasket
should just touch the step plate when door is
closed.

3. Excessive dirt and grease will cause the hinge to
operate improperly. Clean the hinge with silicone
spray to remove dirt and grease from hinge.

NEVER OIL HINGES.

Hinge Installation:

1. Make sure the door is plumb and level. A common cause of
hinge failure is an improperly hung door.

2. With the door closed (securely latched), install shims as
illustrated in Figure 1.

3. Remove the 1/4-20 screws from the top hinge only. The
bottom hinge and magnetic gasket will hold the door in

fasten hinge).

4. Position and fasten the new D-125 hinge using the existing
holes on the door panel (when replacing an older style D­49 door hinge. It will be necessary to drill and tap for a 1/4­20 screw for the top hole for the base). Fasten the hinge
base to the door panel first, and then fasten the blade to
the door cap.

5. Repeat steps 3 and 4 for any other hinges being replaced.

6. Remove all shims and check the operation of the door. If the
door fails to close itself, check door using the Pre-Check
suggestions.

If the door still does not close automatically after making

the suggested checks and corrections. It may be necessary
to replace the existing hinges with Bally's D-125 Hinges.
