NOTES:
1. Connect Y or Y/Y2 terminaI as shown for proper cooling operation.
2. Proper polarity must be maintained for 115-v wiring.
3. Use W2 with 2-stage thermostat when zoning.
4. If any of the original wire, as supplied, must be replaced, use
same type or equivalent wire.
5. Some thermostats require a "C" terminal connection as shown.

[TNIT MAY NOT OPERATE
Failure to %llow this caution may result in intem_ittent unit
operation,
Furnace control must be grounded for proper operation or
control will tock out, (ontrol is grounded through

Be%re proceeding with electrical cormections, make certain that
voltage, fi'equency, and phase con'espond to that specified on
furnace rating plate, Also, check to be sure that sma'ice provided
by power supply is sufficient to handle load imposed by this
equipment Refer to rating plate or Table 4 for equipment electrical
