Wiring - Lennox AIR CONDITIONER Installation Manual

WIRING

Attaching wiring
1. The air conditioner should use separate power supply with rated voltage
2. The external power supply to the air conditioner should have ground wiring, which is linked
to the ground wiring of the indoor and outdoor unit.
3. The wiring work should be done by qualified persons according to circuit drawing.
4. A leakage protector should be installed according to the National Standard concerning
electrical appliance.
5. Be sure to locate the power wiring and the signal wring well to avoid cross-disturbance and
their contact with connecting pipe or stop value body.
6. The wiring attached to this air conditioner is 10m long. Be sure to prolong it with wiring of
the same type and proper length if necessary. Generally, do not twist two wiring together
unless the joint is soldered well and covered with insulator tape.
7. Do not turn on the power until you have checked carefully after wiring.
