Installation Instructions
8 Condensate Drain Connection
Unit should be installed in accordance with national and local safety codes,
including but not limited to ANSI/NFPS No. 70, local plumbing and wastewater
codes and any other applicable codes.
8.1 Install Drain Pipe
1.
Ensure drain lines do not block access to front of the unit. Minimum
clearance of 24 inches is required for fi lter, coil or blower removal and
service access.
2.
Make sure unit is leveled or pitched slightly toward primary drain
connection so that water will drain completely from the pan.
3.
Do not reduce drain line size to less than connection size provided on
condensate drain pan.
4.
All drain lines must be pitched downward away from the unit at a minimum
of 1/8" per foot of line to ensure proper drainage.
5.
Do not connect condensate drain line to a closed or open sewer pipe. Run
condensate to an open drain or run line to a safe outdoor area.
6.
The drain line should be insulated where necessary to prevent sweating and
damage due to condensate forming on the outside surface of the line.
7.
Make provisions for disconnecting and cleaning of the primary drain line
should it become necessary. Install a 2 inch trap in the primary drain line
as close to the unit as possible. Make sure that the top of the trap is below
connection to the drain pan to allow complete drainage of pan.

When making drain fitting connections to the drain pan, use a
thin layer of Tefl on paste, silicone or Tefl on tape and install by hand
tightening.
When making drain fitting connections to drain pan, do not
overtighten. Over tightening fi ttings can split pipe connections on the
drain pan.

9 Air Filter (Not Factory-Installed)
Filters and fi lter racks are not included with the unit and must be fi eld supplied.
An external fi lter or other means of fi ltration must be properly sized for a maximum
of 300 feet/min. air velocity or what is recommended for the type of fi lter installed.
Filter application and placement are critical to airfl ow, which may aff ect the heating
and cooling system performance. Reduced airfl ow can shorten the life of the
system's major components, such as motor, elements, heat relays, evaporator coil
or compressor. Consequently, we recommend that the return air duct system have
only one fi lter location. For systems without a return air fi lter grill, multiple fi lter
grills can be installed at each of the return air openings.
If adding high effi ciency fi lters or electronic air fi ltration systems, it is very
important that the air fl ow is not reduced. If air fl ow is reduced the overall
performance and effi ciency of the unit will be reduced. It is strongly recommended
that a professional installation technician is contacted to ensure such fi ltration
systems are installed correctly.

Do not double fi lter the return air duct system. Do not fi lter the
supply air duct system. This will change the performance of the unit and
reduce airfl ow.
WARNING: FIRE HAZARD
Do not operate the system without filters. A portion of the
dust suspended in the air may temporarily lodge in the
duct runs and at the supply registers. Any circulated dust
particles could be heated and charred by contact with the
air handler elements. This residue could soil ceilings, walls,
drapes, carpets and other articles in the house.
Soot damage may occur with filters in place, when certain
types of candles, oil lamps or standing pilots are burned.
