INSTALLATION

GROUND LEVEL -- HORIZONTAL UNITS

For ground level installations, the unit should be positioned on a pad the size of the unit or larger. The unit must be level on the pad. The pad must not come in contact with the structure (See Figure 11.) Be sure the outdoor portion of the supply and return air ducts are as short as possible.

Proceed with the installation as follows:

1.Place the unit on the pad and the five (5) rubber isolators provided.

2.Attach the supply and return air ducts to the unit.

3.Insulate any ductwork outside of the structure with at least 2 inches of insulation and weatherproof. There must be a weather- proof seal where the duct enters the structure.

4.Complete the installation according to the instructions in the following sections of this manual.

CONDENSATE DRAIN PIPING

A 3/4-inch female NPT condensate drain connection is provided on the evaporator access panel end of the unit. See Figure 4. Provide a trap and fill it with water before starting the unit to avoid air from being drawn through. Follow local codes and standard piping practices when running the drain line. Pitch the line downward away from the unit. Avoid long horizontal runs. See Figure 12.

NOTE: Do not use reducing fittings in the drain lines. The condensate drain must be:

Made of 3/4" pipe size.

Pitched 1/4" per foot to provide free drainage to convenient drain system.
