Replacing D-1250 spring-loaded hinges on Walk-In door panels
A. Close the door. Securely hold the door in place by
shimming between the outside doorcap and the door
frame. Remove the slotted machine screws from the
hinge base and blade. If tamperproof screws are used
See Figure 5. Remove the defective hinge assembly.
Secure the new hinge assembly with a screwdriver by
tightening the machine screws in the same holes.
B. Remove the shims from around the perimeter of the
door frame.
C. Open the door and check for proper operation and seal.
Shimming Walk-In door hinges
A. If the Walk-In door is installed properly, no shimming is
required. Shim only where misapplication or poor
installation of the door panel have caused the door
cap to seal improperly. If the door cap toes outward at
the top or bottom of the latch side of the panel, shim
the diagonally opposite hinge base outward, forcing
the corner of the door cap back into alignment with
the door frame for a positive seal. See Figure 6.
B. To shim hinges on Walk-In doors, loosen the machine
screws on the base of the hinge enough to slip the
required number of shims into place behind the base.
See Figure 7. Where tamper-proof screws are used,
loosen them by tapping the screw head
counterclockwise with a center-punch and hammer as
shown in Figure 5.
C. Retighten machine screws and check door cap for
proper seal.
