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.
TO PREVENT SHORTENING ITS SERVICE LIFE, THE
AIR HANDLER SHOULD NOT BE USED DURING THE
FINISHING PHASES OF CONSTRUCTION OR REMOD-
ELING. The low return air temperatures can lead to the
formation of condensate. Condensate in the presence
of chlorides and fluorides from paint, varnish, stains,
adhesives, cleaning compounds, and cement creates a
corrosive condition which may cause rapid deteriora-
tion of the cabinet and internal components.
