GENERAL INFORMATION

General

The equipment covered in this manual is to be 
installed by trained, experienced service and 
installation technicians.
This appliance is not intended for use by persons 
(including children) with reduced physical, sensory 
or mental capabilities, or lack of experience and 
knowledge, unless they have been given supervision or 
instruction concerning use of the appliance by a person 
responsible for their safety.
Children should be supervised to ensure that they do 
not play with the appliance.
The refrigerant system is completely assembled and 
charged. All internal wiring is complete.
The unit is designed for use with or without duct work. 
Flanges are provided for attaching the supply and 
return ducts.
These instructions explain the recommended method 
to install the air cooled self-contained unit and the 
electrical wiring connections to the unit.
These instructions and any instructions packaged with 
any separate equipment required to make up the entire 
air conditioning system should be carefully read before 
beginning the installation. Note particularly “Starting 
Procedure” and any tags and/or labels attached to the 
equipment.
While these instructions are intended as a general 
recommended guide, they do not supersede any 
national and/or local codes in any way. Authorities 
having jurisdiction should be consulted before 
the installation is made. See following section for 
information on codes and standards.
Size of unit for a proposed installation should be based 
on heat loss calculation made according to methods of 
Air Conditioning Contractors of America (ACCA). The 
air duct should be installed in accordance with the 
Standards of the National Fire Protection Association 
for the Installation of Air Conditioning and Ventilating 
Systems of Other Than Residence Type, NFPA No. 
90A, and Residence Type Warm Air Heating and Air 
Conditioning Systems, NFPA No. 90B. Where local 
regulations are at a variance with instructions, installer 
should adhere to local codes.

Shipping Damage

Upon receipt of equipment, the carton should be 
checked for external signs of shipping damage. If 
damage is found, the receiving party must contact 
the last carrier immediately, preferably in writing, 
requesting inspection by the carrier’s agent.
