2.5 Leveling legs

Leveling legs are designed to provide extra front support

and leveling of the wall sleeve. Two leg assemblies are

needed by each unit and each leg assembly requires two

screws for attaching them to the wall .

These leveling legs must be installed before the installa-

tion of the chassis but after the wall sleeve is in position.

Holes must be drilled on each side of the wall sleeve

below the duct package holes, as shown on the figure on

the right, for attaching it to the wall sleeve.

Installation Procedure:

The Installation and servicing of the equipment should

be performed by qualified and experienced personnel

only.

1) At first, drill two 1/8 – inch holes in each side of the

wall sleeve as shown in the figure on the right(using

the leveling leg assembly as a template). The holes

should be drilled near the front of the sleeve for the

leveling legs to provide better support to the wall

sleeve and the weight of the unit.

2) Adjust the leveling legs to the required height and

then install them on either side of the wall sleeve by

means of screws. Caulk or seal the screws to prevent

any water leaks from these screw points.

3) Adjust the level of the sleeve horizontally from side to

side. Provide a slight slope (one quarter bubble in the

sight glass) towards outside (other side of the room).

Check the level again after the unit has been installed

and adjust the legs further if necessary.
