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 Page 3 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.

GENERAL

The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.

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.
