Close enclosure door and slowly turn the handle to the
right (counterclockwise) until the first notch on the
cam plate is engaged. At this point positive gasket seal
should be obtained with proper roller adjustment.
When seal is obtained further adjustment to the de-
feater actuator lever may be required if the operator
mechanism handle can be moved to the “On” position.
Rotate door handle further to the right. Relocate
defeater actuator lever if necessary, so that the opera-
ting handle mechanism “On” position occurs well
before the fully latched (vertical) door handle position.
With the operating handle in the “Off” position, turn
recessed door defeater screw, hold and simultaneously
turn handle to the left and pull. Door should open.
Close door, turn door handle to fully latched position
and place disconnect switch in “On” position. Turn
recessed door defeater screw, hold and at the same
time turn door handle to the left and pull. Door should
open only partially. Maintain force on handle and turn
recessed defeater screw in cabinet flange. The door
should now open.
Close door and rotate door handle to the fully closed
position. Pull out handle padlocking bar. Insertion of a
3/16" minimum to 3/8" maximum lock hasp should
prevent against movement of the door handle.
