2.2.14 Install Doors
Install Doors, Figure 2.2.24. Each Door weighs 35 pounds.
Orient the Doors so their Latches grip the Cross Bars. Handles are closer to the End Panels and
the Cross Bars than to the inlet/outlet faces.
Check for good compression of the DOOR gaskets. If necessary, adjust the inner latch to provide
proper compression. Use a 1/8" allen wrench to loosen and re-tighten the set screw.
