WIRING DIAGRAM
NOTES:
1. Disconnect power before servicing.
2. For supply connections use copper conductors only.
3. Not suitable on systems that exceed 150V to ground.
1. Couper le courant avant de faire letretien.
2. Employez uniquement des conducteurs en cuivre.
3. Ne convient pas aux installations de plus de 150 V
a la terre.
4. If any of the original wire as supplied with the furnace must be replaced, it must
be replaced with wiring material having a temperature rating of at least 105°C.
5. For supply wire ampacities and overcurrent protection, see unit rating plate.
6.For 208V operation,inducer motor low speed resistor must be bypassed.
Removed RED wire from resistor block and connect to piggyback terminal
on opposite side.
