WARNING
!
THIS INFORMATION IS FOR USE BY INDIVIDUALS
HAVING ADEQUATE BACKGROUNDS OF ELECTRICAL
AND MECHANICAL EXPERIENCE. ANY ATTEMPT TO

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 Sec-
tion C beginning on page 3 for additional information.

tion. When units are installed in unconditioned spaces,
verify that all electrical and refrigerant line penetrations
on the air handler are sealed completely.
