Units equipped with spring-mounted compressors have shipping
spacers that are designed to hold compressor rigidly during
transit. It is necessary to remove spacers before operating
the unit. To remove shipping spacers, follow these steps: |
| |
a) Remove
the upper nuts/washer.
b) Discard the shipping spacers.
c) Install the rubber cone washers (located in electrical box).
d) Replace the upper mounting nuts/washers.
e) Allow 1/16 inch space between the mounting nuts / washers
and the compressor foot.

| On
units equipped with rigid mounted compressors, check the compressor
mounting bolts to ensure they have not vibrated loose during
shipping. |
