Notes:
1. WIRING SHOWN WITH DASHED LINES IS TO BE FURNISHED AND INSTALLED
BY THE CUSTOMER. ALL CUSTOMER SUPPLIED WIRING MUST BE COPPER
ONLY AND MUST CONFORM TO NEC AND LOCAL ELECTRICAL CODES.
CODES MAY REQUIRE LINE OF SIGHT BETWEEN DISCONNECT SWITCH
AND UNIT.
2. WHEN ELECTRIC HEATER ACCESSORY IS USED SINGLE POINT POWER
ENTRY OR DUAL POINT POWER ENTRY IS FIELD OPTIONAL, SINCE
POINT POWER ENTRY OPTION IS THROUGH ELECTRIC HEATER ONLY.
Installation
OPEN THE ELECTRICAL
DIS-CONNECT SWITCH AND LOCK IN OPEN
POSITION TO PREVENT ACCIDENTAL POWER
APPLICATION. FAILURE TO DO SO MAY RESULT IN
PERSONAL INJURY OR DEATH DUE TO ELECTRICAL
SHOCK.
Determine proper wire sizes and unit protective fusing
requirements by referring to the unit nameplate and/or the
unit Service Facts. Field wiring diagrams for accessories
are shipped with the accessory.
Low Voltage Wiring
Mount the indoor thermostat in accordance with the
thermostat installation instructions. Install color-coded,
weather-proof, multi-wire cable according to the
Interconnecting Wiring diagrams in the Air Handler IOM.
