ALL FIELD WIRING MUST MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE (ANSI/NFPA

THE FIELD-PROVIDED CIRCUIT PROTECTION DEVICE (HACR CIRCUIT BREAKER OR TIME DELAY FUSE) MUST NOT EXCEED THE
AMPACITY INDICATED ON THE PRODUCT NAMEPLATE.
IMPORTANT: Before you begin the actual installation of your air conditioner, check local electrical codes and the information below.
Your power supply must be the same A.C. voltage and frequency (hertz) as marked on the name plate located on the chassis. Only
alternating current (A.C.), no direct current (D.C.), can be used.
An overloaded circuit will invariably cause malfunction or failure of the air conditioner; therefore, it is extremely important that the
electrical power is adequate. Consult your dealer or power company if in doubt.
