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.
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.
Trapped.
Must not be connected to closed drain system.
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.
