SECTION VI: OPTIONAL AIR
CONDITIONING ACCESSORIES
This furnace is already equipped with a blower and control system to
add-on air conditioning and heat pump. Insulation and coil shelf kit
(3500-8941* for downflow or 3500-8961* for upflow) must be installed
when adding on such remote air conditioning systems.
HIGH PERFORMANCE BLOWER ACCESSORY PACK-
AGE
All EB furnaces are equipped with a blower and control system to add-
on air conditioning and heat pumps to specified sizes. If the require-
ment is to achieve more air flow or cooling than specified, then the
blower inside the furnace has to be replaced with an accessory blower
package 3500-7901*. This accessory blower package would deliver air
conditioning up to 5-tons, and heat pump up to 4-tons. Accessory pack-
age (3500-7901*) includes blower, insulation, coil shelf, trap, clamps,
etc. Please refer to the installation instructions packed with the acces-
sory package for more information.
Failure to install this insulation and coil shelf kit could result in
damage to equipment and/or personal injury. Liability and war-
ranty from the manufacturer could also be void.
All areas around the line sets, drain hoses and other openings in
the coil shelf should be sealed air tight. Use some moldable com-
pound or caulking to seal the area. Failure to do so may result in
loss of performance and premature compressor failure.
