Step 1

Determine the orientation of the door.

The VPRG4 Kit comes with two mounting hinges. One mounts to the left side of the opening and locates the return air openings at the lower portion of the door (View A).

The other mounts the hinge to the right side of the opening and locates the return air openings at the upper portion of the door (View B).

This provides an option for the direction that the door will open. More importantly it can aid in sound attenuation by locating the return air openings away from the evaporator opening on the unit.

NOTE: For maximum sound attentuation it is recommended that the left hand bracket (View A) be used for VEA/VHA24 models and the right hand bracket (View B) be used for VEA/VHA09, 12 and 18 models.

Follow STEPS 2A through 6A (next page) for left side mounting (View A)

Follow STEPS 2B through 6B (next page) for right side mounting (View B).
