NOTES:
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. THE THERMOSTAT/CONTROL CONNECTED TO THIS
UNIT MUST BE DUAL FUEL CAPABLE.
4. FACTORY WIRED FOR 230 VOLT SUPPLY POWER.
FOR 208 VOLT, MOVE BLACK WIRES FROM THE 230
TO THE 208 VOLT TAP ON THE TRANSFORMER.
5. MOTORS ARE INHERENTLY PROTECTED.
6. SEE UNIT NAMEPLATE FOR MAXIMUM FUSE AND/OR
CIRCUIT BREAKER SIZE AND MINIMUM CIRCUIT AMPACITY.
7. SELECT COOLING (YELLOW) BLOWER SPEED THAT WILL
DELIVER APPROXIMATELY 400 CFM/TON FOR COOLING
AND HEAT PUMP OPERATION.
8. BLOWER MOTOR SPEED CONNECTIONS SHOWN ARE
TYPICAL, BUT MAY VARY BY MODEL AND APPLICATION.
