Installation In struc tions
Read This First! Electrical Requirements
IMPORTANT: Before you begin the actual installation of your air conditioner,
check local electrical codes and the information below.
Your air conditioner must be connected to a power supply with the same
A.C. voltage and hertz as marked on the data plate located on the chassis.
Only alternating current (A.C.), can be used. Direct Current (D.C.) cannot be
used. Refer to page 3 for the correct type of receptacle for your model.
CIRCUIT PROTECTION - USE ON SINGLE OUTLET CIRCUIT ONLY.
An over load ed circuit will in vari ably cause mal func tion or fail ure of an air
con di tion er, there fore, it is nec es sary that the electrical pro tec tion is ad e -
quate. Due to mo men tary high cur rent de mand when your air con di tion er is
start ed, use a "TIME DELAY" fuse or a HACR type circuit breaker. Consult
your dealer or power company if in doubt.
Refer to the electrical data plate located on the air conditioner chassis to
determine the cor rect fuse or circuit breaker amperage for your model (See
Figure E on Page 16 for electrical receptacle location).
The power cord has a plug with a grounding prong of approved type and
a matching receptacle is required.
WARNING: NEVER CUT OR REMOVE THE GROUNDING PRONG
FROM THE PLUG. NEVER USE EXTENSION CORDS TO OPERATE
AN AIR CONDITIONER.
