This product is designed and manufactured to permit instal-
lation in accordance with National Codes. It is the installer’s
responsibility to install the product in accordance with National
Codes and/or prevailing local codes and regulations.
The heating and cooling capacities of the unit should be greater
than or equal to the design heating and cooling loads of the
area to be conditioned. The loads should be calculated by an
approved method or in accordance with ASHRAE Guide or
Manual J - Load Calculations published by the Air Conditioning
Contractors of America.

System design and installation should also, where applicable,
follow information presented in accepted industry guides such
as the ASHRAE Handbooks. The manufacturer assumes no
responsibility for equipment installed in violation of any code
or regulation. The mechanical installation of the packaged roof
top units consists of making final connections between the unit
and building services; supply and return duct connections; and
drain connections (if required). The internal systems of the unit
are completely factory-installed and tested prior to shipment.
Units are generally installed on a steel roof mounting curb as-
sembly which has been shipped to the job site for installation
on the roof structure prior to the arrival of the unit. The model
number shown on the unit’s identification plate identifies the
various components of the unit such as refrigeration tonnage,
heating input and voltage.
Carefully inspect the unit for damage including damage to the
cabinetry. Any bolts or screws which may have loosened in
transit must be re-tightened. In the event of damage, the re-
ceiver should:
1. Make notation on delivery receipt of any visible damage to
shipment or container.
2. Notify carrier promptly and request an inspection.
3. In case of concealed damage, carrier should be notified as
soon as possible-preferably within 5 days.
4. File the claim with the following supporting documents:
a. Original Bill of Lading, certified copy, or indemnity
bond.
b. Original paid freight bill or indemnity in lieu thereof.
c. Original invoice or certified copy thereof, showing trade
and other discounts or reductions.
d. Copy of the inspection report issued by carrier repre-
sentative at the time damage is reported to the carrier.
The carrier is responsible for making prompt inspection
of damage and for a thorough investigation of each
claim. The distributor or manufacturer will not accept
claims from dealers for transportation damage.
NOTE:
When inspecting the unit for transportation damage,
remove all packaging materials. Recycle or dispose of the
packaging material according to local codes.

Ote
:
Unit should be energized 24 hours prior to
compressor start up to ensure crankcase heater has sufficient-
ly warmed the compressors. Compressor damage may occur if
this step is not followed.
NOTE:
Appliance is shipped from factory for vertical duct appli-
cation.
Proper installation of the unit ensures trouble-free operation.
Improper installation can result in problems ranging from
noisy operation to property or equipment damages, danger-
ous conditions that could result in injury or personal proper-
ty damage and that are not covered by the warranty. Give
this booklet to the user and explain it’s provisions. The user
should retain these instructions for future reference.
• For proper flame pattern within the heat exchanger and
proper condensate drainage, the unit must be mounted lev-
el.
• The flue outlet must be at least 12 inches from any opening
through which flue gases could enter a building, and at least
three feet above any forced air inlet located within ten feet.
The economizer/manual fresh air intake/motorized fresh air
intake and combustion air inlet mounted on the unit are not
affected by this restriction.
• To avoid possible corrosion of the heat exchanger, do not
locate the unit in an area where the outdoor air (i.e. com-
bustion air for the unit) will be frequently contaminated by
compounds containing chlorine or fluorine. Common sourc
-
es of such compounds include swimming pool chemicals
and chlorine bleaches, paint stripper, adhesives, paints,
varnishes, sealers, waxes (which are not yet dried) and
solvents used during construction and remodeling. Various
commercial and industrial processes may also be sources
of chlorine/fluorine compounds.
