ER
USE ONLY TYPE AND SIZE FUSE OR HACR CIR- CUIT BREAKER INDICATED ON UNIT’S
RATING GUIDE. PROPER OVER CURRENT PROTECTION TO THE UNITS IS THE RESPON-
SIBILITY OF THE OWNER.
GROUNDING UNIT MUST BE GROUNDED FROM BRANCH CIRCUIT TO UNIT, OR THROUGH SEPARATE
GROUND WIRE PROVIDED ON PERMANENTLY CONNECTED UNITS. ENSURE THAT
BRANCH CIRCUIT OR GENERAL PUR- POSE OUTLET IS GROUNDED.
WIRE SIZING USE RECOMMENDED WIRE SIZE GIVEN IN TABLES AND INSTALL A SINGLE BRANCH
CIRCUIT. ALL WIRING MUST COMPLY WITH LOCAL AND NATIONAL CODES. NOTE: USE

WARNING
Electrical Shock Hazard.
Turn OFF electric power before service or instal-
lation.
Unit must be properly grounded.
Unit must have correct fuse or circuit breaker pro-
tection. Unit’s supply circuit must have the correct
wire conductor size. All electrical connections and
and conform to the National Electrical Code and all
local codes which have jurisdiction. Failure to do so
can result in property
damage, personal injury and/or death.
NOTE: ALL 230/208 CHASSIS MUST BE HARD WIRED WITH A PROPERLY SIZED BREAKER. SEE UNIT NAMEPLATE
FOR SPECIFIC ELECTRICAL REQUIREMENTS.
USE HACR TYPE BREAKERS TO AVOID NUISANCE TRIPS. ALL FIELD WIRING MUST BE DONE IN ACCORDANCE
WITH NEC AND LOCAL CODES. IT IS THE INSTALLER’S
RESPONSIBILITY TO ENSURE THAT THE ELECTRICAL CODES ARE MET.
