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 systems
or provide for every possible contingency. Should fur-
ther information be desired or particular problems arise
which are not covered sufficiently by this manual, con-
tact 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 B beginning on page 3 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.
CAUTION
!
Cardboard packing material must be removed from in-
side the blower assembly before starting the unit.
Failure to do so may cause indoor blower motor failure.
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.
NOTE: CONDENSATION MAY OCCUR ON THE SUR-
FACE OF THE AIR HANDLER WHEN INSTALLED IN AN
UNCONDITIONED LOCATION. WHEN UNITS ARE IN-
STALLED IN UNCONDITIONED SPACES, VERIFY THAT
ALL ELECTRICAL AND REFRIGERANT LINE PEN-
ETRATIONS ON THE AIR HANDLER ARE SEALED
COMPLETELY.
