1. ALL FIELD WIRING TO BE ACCOMPLISHED FOLLOWING CITY, LOCAL AND/OR

NATIONAL CODES IN EFFECT AT THE TIME OF INSTALLATION OF THE UNIT.

2. CAUTION : LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING

CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS
OPERATION. IF ANY OF THE WIRING, AS SUPPLIED WITH THE UNIT, MUST
BE REMOVED, IT MUST BE REPLACED WITH TYPE 105 C. 600 VOLT
WIRE OR EQUIVALENT CLEARLY RENUMBERED FOR IDENTIFICATION.
VERIFY PROPER OPERATION AFTER SERVICING.

3. FACTORY WIRED FOR 230 VOLT SUPPLY POWER. FOR 208 VOLT,  MOVE

BLACK WIRES FROM THE 230 TO THE 208 VOLT TAP ON THE TRANSFORMER.

4. MOTORS ARE INHERENTLY PROTECTED.

5. SEE UNIT NAMEPLATE FOR MAXIMUM FUSE AND/OR CIRCUIT BREAKER SIZE

AND MINIMUM CIRCUIT AMPACITY.

6. SELECT INDOOR BLOWER SPEED TO REMAIN WITHIN THE TEMPERATURE

RISE RANGE ON THE NAMEPLATE IN HEATING AND TO OBTAIN APPROX.
400 CFM/TON IN COOLING.

7. BLOWER MOTOR SPEED CONNECTIONS SHOWN ARE TYPICAL,

BUT MAY VARY BY MODEL AND APPLICATION.
