3.0 DUCTWORK
Duckwork should be made and sized by installer and in accordance with Air
Manual from Conditioning Contractors of America and local codes.
On ductwork exposed to outside air conditioning space, use at least 2" of
insulation and a vapor barrier. Flexible joint may be used to reduce noise.
A closed return duct system shall be used. This shall not preclude use of
economizers or ventilation air intake. Flexible joints may be used in the
supply and return duct work to minimize the transmission of noise.
When fastening duct work to the side duct flanges on the unit, insert the
screws through the duct flanges only. DO NOT insert the screws through
the casing. Outdoor duct work must be insulation and waterproofed.
Be sure to note supply and return openings. Refer to Fig. 2-2 and 2-3
for information concerning supply and return air duct openings.

4.0 CONDENSATE DRAIN CONNECTION

Consult local codes for special requirements.
To provide extra protection from water damage, install an additional drain pan,
provided by installer, under the entire unit with a separate drain line. Manufac-
turer will not be responsible for any damages due to the failure to follow these
requirements.

4.1 INSTALL DRAIN PIPE

1. Use female NPT threaded fitting for outside connection and make sure that
drain holes are not blocked.
2. Insulation may be needed for drain line to prevent sweating.
3. Drain pan has two drain connections on each side to provide flexibility of
connection and drainage. Make sure proper pitch and plugging if second
connection is not used.
4. Use a sealing compound on male pipe threads. Install the condensate
drain line (NPT) to spill into an open drain.
