NOTE: THIS MANUAL INCLUDES INSTALLATION INSTRUCTIONS FOR BOTH WINDOW MOUNT AND THROUGH-
THE-WALL INSTALLATIONS
Electrical Requirements
ALL FIELD WIRING MUST MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE (ANSI/NFPA 70)
ARTICLE 501.
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 air conditioner must be connected to a power supply with the same A.C. voltage and frequency (hertz) as marked on the data
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.
The following instructions are for HAZARDGARD models and cabinet sizes listed below.
