INSPECTION AND UNPACKING
CONGRATULATIONS
You have made a major investment in a fine piece of equipment. Keep
your investment sound by reading these instructions before installing
this unit. This will ensure that the full potential of this equipment is
achieved. It will also be helpful in avoiding any needless service costs
or operational problems. Included in these instructions are safety
rules, installation, maintenance, and operation instructions.
Your equipment is covered by a LIMITED WARRANTY against
defects in material and workmanship. Make sure that your installing
dealer or contractor has returned the factory portions of the
LIMITED WARRANTY CARD with the information properly entered
to confirm the date of installation. Failure to return the warranty card
could result in the warranty period beginning at the date of
manufacture, instead of the date of installation.
Only the highest quality components were used in the construction
of your unit. With proper maintenance, your system should provide
years of economical, trouble-free service.
This is a vertical wallmount unit designed for many different
applications in both residential and commercial settings. It is self-
contained and arrives completely assembled, factory-charged and
wired. The unit is 100% run-tested at the factory to ensure proper
operation. Your unit is supplied with high-quality copper tubing and
enhanced aluminum-finned coils for high heat transfer efficiency
and long life. The unit cabinet is constructed of G-90 galvanized
steel. All exterior surfaces are finished with a baked-on polyester
coating. This will provide excellent corrosion protection in most
applications. However, if the unit is installed in an area with a
corrosive atmosphere, such as near an industrial plant or on the
seacoast, additional coating should be considered to extend the life
of the coils and cabinet.
The words “SHALL” and “MUST” indicate a requirement which is
essential to satisfactory and safe product performance. The
words “SHOULD” and “MAY” indicate a recommendation or
advice which is not essential and not required but which may be
useful or helpful.
The instructions are for the use of qualified individuals specially trained
and experienced in the installation of this type equipment and related
system components.
Installation and service personnel are required by some locales to be
licensed. Persons not qualified SHALL NOT install this equipment nor

SHALL NOT be deemed to extend, modify, alter or expand any of the
representations contained in the LIMITED WARRANTY.
