12.7 Door Adjustment
Occasionally due to racking occurring in transit or uneven storage or placement, the service doors may require
adjustment. The following is a step-by-step process for adjustment of the air handler service doors:
To adjust the ClimateCraft Door vertically or
horizontally only one tool is required; a 1/8” Allen
Wrench (tool shown in photo).
To tighten the door handles use two 9/16” wrenches.
On inward opening doors a T-27 is needed to adjust
the location of the roller cam. Using the same T-27 to
tighten the set bolt on the roller cam to lock in location
desired for proper operation.
A T-27 is a torque drive socket not to be confused
with a star drive.
Using an 1/8” Allen Wrench:
1. Vertical Adjustment
2. Hinge Pressure Adjustment
3. Horizontal Adjustment

The Hinge Pressure Adjustment will allow additional
pressure to be placed on the hinge side of the door to
eliminate any leaks.
