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. Consult your "OPERATING
GUIDE" for the correct type of receptacle for your model.
CIRCUIT PROTECTION - USE ON SINGLE OUTLET CIRCUIT ONLY unless all amp values on the nameplate are 7.5 or
less. An overloaded circuit will invariably cause malfunction or failure of an air conditioner, therefore, it is necessary that the elec-
trical protection is adequate. Due to momentary high current demand when your air conditioner is started, use a "TIME DELAY"
fuse or a HACR 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 correct fuse or circuit breaker amperage for
your model (See Figure E on Page 12 for electrical receptacle location).
The power cord has a plug with a grounding prong of approved type and a matching receptacle is required. NEVER CUT OR
REMOVE THE GROUNDING PRONG FROM THE PLUG.
NEVER USE EXTENSION CORDS TO OPERATE AN AIR CONDITIONER.
The following instructions are for standard chassis model groups distinguished by the first two letters of the model designations
