A. GENERAL INFORMATION
▲
WARNING
!
THIS INFORMATION IS FOR USE BY INDIVIDUALS
HAVING ADEQUATE BACKGROUNDS OF ELECTRICAL
AND MECHANICAL EXPERIENCE. ANY ATTEMPT TO
REPAIR A CENTRAL AIR CONDITIONING PRODUCT
MAY RESULT IN PERSONAL INJURY AND/OR PROP-
ERTY DAMAGE. THE MANUFACTURER OR SELLER
CANNOT BE RESPONSIBLE FOR THE INTERPRETA-
TION OF THIS INFORMATION, NOR CAN IT ASSUME
ANY LIABILITY IN CONNECTION WITH ITS USE.
▲
CAUTION
!
To prevent shortening its service life, the air handler
should not be used during the finishing phases of con-
struction. The low return air temperatures can lead to
the formation of condensate. Condensate in the pres-
ence of chlorides and fluorides from paint, varnish,
stains, adhesives, cleaning compounds, and cement
creates a corrosive condition which may cause rapid
deterioration of the cabinet and internal components.
These instructions do not cover all variations in sys-
tems or provide for every possible contingency. Should
further information be desired or particular problems
arise which are not covered sufficiently by this manual,
contact your local distributor or the manufacturer as
listed on the air handler nameplate.
These air handlers are shipped from the factory in the
upflow or horizontal right configuration and are fully
convertible to downflow or horizontal left. Refer to
Section C beginning on page 4 for additional informa-
tion.
INSPECTION
Check carefully for any shipping damage. This must
be reported to and claims made against the transpor-
tation company immediately. Check to be sure all
major components are in the unit. Any missing parts
should be reported to your supplier at once, and re-
placed with authorized parts only.
INSTALLATION LIMITATIONS & RECOMMENDATIONS
The general location of the air handler is normally
selected by the architect, contractor and/or home owner
for the most effective application and satisfaction.
These air handlers are suitable for installation in a
closet, alcove or utility room with free, non-ducted, air
return, using the area space as a return air plenum.
With ducted supply air, if the minimum clearances to
combustible materials and service access are observed,
the above installations are suitable.

Two secondary drain connections are provided for the
different orientations (See Figure 6). The lower of the
two should be connected as a backup to prevent conden-
sate overflow by a blocked primary drain.
For proper drainage of condensate, the following steps
should be followed:
1. The primary drain line must be trapped with a
minimum of 2" water seal as shown in Figures 15 &
16. Do not use preformed 3/4" PVC running
traps.
The use of Field fabricated or manufactured traps
as shown in Figures 15 & 16 is acceptable. The
manufactured trap shown in Figure 15 allows for a
float switch option to be added.
Refer to the manufacturers data and instructions
for details.
2. The trap must be located within 4 feet of the air
handler drain outlet connection.
3. It is recommended that a clean-out tee or cross be
installed in the primary drain line for future main-
tenance (See Figure 15 & 16).
1. Refrigerant connections are made outside the cabi-
net.
2. Installation of refrigerant lines is covered in the in-
stallation instructions packaged with the outdoor
unit. Evacuation, leak testing and brazing proce-
dures are included in those instructions. Read those
instructions before starting installation of refriger-
ant lines.
