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.

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/gain 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.

Note 

  All 230/208V units with or without electric heat have circuit breaker.  0C is for 460V circuit breaker & 0KW.  No 460V electric heat options w/circuit 

breaker available.  460V -0Z and all 460V KW options are with Rotary Disconnect.  See available heater options by unit model number.
