1. If the door of a 700-2 tall unit will not close properly, first check for obstructions.
2. If there are no obstructions, open the door approximately 1" and let it go to see if it closes on its own. Repeat
this three times.
3. If the door fails to close, remove the door gasket and repeat opening the door approximately 1", then let go. If
the door does not close past parallel with the gasket seat, go to step #4 below. If the door does close past par-
allel with the gasket seat, this may indicate that the door gasket was binding on the hinge side. If so, the door
hinges can be shimmed out slightly.
To shim a hinge out, remove the door from the unit. Then, extract the hinge mounting bolts and pull the hinges
from the unit. Place washers (part #6240360) behind the hinges. Reinstall the hinges and hinge mounting
bolts. (See Figure 9-3) Replace the door gasket and reattach the door, then retest the door closing operation.
NOTE: Placing too many washers behind the hinges may cause air leaks. Check for air leaks after reattaching
the door.
4. If the door did not close past parallel with the gas-
ket off, remove the top hinge cover and extract
the one top door hinge screw closest to the pivot
point of the hinge. Loosen the three remaining
top hinge screws almost all the way out. Now,
open the door approximately 1"and let go to see if
it closes on its own.
If door closes, install the 700 Series Hinge Shims
Package, part #4202290. (See Figure 9-4) If the
door fails to close, remove the three remaining
screws from the top door hinge and check the
closing action of the hinge on its own. If it seems
weak, replace it. If it does not seem weak, rein-
stall the top door hinge screws and go to step #5
below.
5. If the door passed the test in step #4 above,
remove the bottom hinge cover and extract the
one bottom door hinge screw closest to the pivot
point of the hinge. Loosen the three remaining
bottom hinge screws almost all the way out. Now,
open the door approximately 1" and let go to see
if it closes on its own.
If door closes, install 700 Series Hinge Shims
Package, part #4202290. If door fails to close,
remove the three remaining screws from the bot-
tom door hinge and check the closing action of
the hinge on its own. If it seems weak, replace it.
