All areas around the line sets, drain hoses and other
openings in the coil sheff should be sealed air tighL
Use some moldable compound or caulking to seal
the area. Failure to do so may result in loss of per-
formance and premature compressor failure.
All EB furnaces are already equipped with a blower and con-
trol system to add-on air conditioning up to 4-tons and heat
pump up to 3 1/2-tons. If the requirement is to achieve more
than specified than the production blower inside the furnace
would have to be replaced with an accessory blower package

conditioning up to 5-tons, and heat pump up to 4-tons. Acces-
sory package (3500-7901")includes blower, insulation, coil
shelf, trap, clamps, etc. Please refer to the installation instruc-
tions packed with the accessory package for more informa-
tion.
