Evaporator Condensate Drain
Install the plastic drain tube (furnished) over the 5/8” O.D. fitting
in the center of the Evaporator condensate pan. Connect other
end of the drain tube to the open trap (see Figure 2). The plastic
drain connection is provided so that it may be disconnected from
the permanent drain tubing in the building in the event it becomes
necessary to remove the cooling chassis assembly.
The drain line should pitch gradually downward at least 1” per
10’ of horizontal run to the open drain trap.
Be certain that the plastic drain tube has free drainage and is not
crimped or flattened at any bend.
Installing Without a Wall Sleeve
Refer to the following directions and Figure 1 for guidance in
installing the unit without a wall sleeve:
1. Measure the size of the unit and provide an opening in an
outside wall that will accept the unit. Local ordinances may
require a steel lintel to support the wall above the opening.
The opening must be square in all four corners.
2. Position the unit so that the grilles on the outside face of the
unit are flush or extend beyond the face of the exterior wall,
but not recessed more than 2” from the face of the building.
Provide a support under the unit, inside the building. Make
sure that the inside support does not block the return air.
The unit should be installed level or pitched slightly to the
outside of the building so that rain water will drain away.
3. Seal the space between the unit and building opening using
a non-hardening caulking compound. The seal must be
weathertight to prevent entrance of moisture and water into
the building. Make sure the drain holes in the base are not
plugged with caulking.
