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.
This unit is equipped with an integrated high efficiency
Whole House Air Cleaner. Careful consideration must
be taken in the installation process to avoid personal in-
jury or equipment damage. These instructions do not
cover all variations in systems or provide for every pos-
sible contingency. Should further information be desired
or particular problems arise which are not covered suffi-
ciently by this manual, contact your local distributor or
the manufacturer as listed on the air handler name-
plate.
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 Sec-
tion C beginning on page 4 for additional information.
INSPECTION
Check carefully for any shipping damage. This must be
reported to and claims made against the transportation
company immediately. Check to be sure all major com-
ponents are in the unit. Any missing parts should be re-
ported to your supplier at once, and replaced with au-
thorized parts only.

INSTALLATION LIMITATIONS & RECOMMENDATIONS
The general location of the air handler is normally se-
lected by the architect, contractor and/or home owner
for the most effective application and satisfaction.
NOTE: Condensation may occur on the surface of the
air handler when installed in an unconditioned loca-
tion. When units are installed in unconditioned spaces,
verify that all electrical and refrigerant line penetrations
on the air handler are sealed completely.
