Outdoor Electrical Connection

1. Remove the control cover from the unit by loosening the fasten-

ing screw.

2. Take off the caps on the conduit panel.

3. Connect both the power supply and low voltage lines to the

corresponding terminals on the terminal block.

4. Be sure to ground the unit by following local codes.

5. Allow for enough length (add several inches) for each wiring.

6. Secure the cable with the cord clamp.

7. Secure conduit tubes with lock nuts.

8. Reattach the control cover to the original position with the fasten-

ing screw.

• Separately wire the high and low voltage lines. There is a risk of

electric shock, physical injury, or death.

• Use heat-proof electrical wire capable of withstanding temperatures

up to 167°F to avoid wiring malfunction and electrical shock, which

may cause physical injury or death.

• Ensure you connect the wire firmly. Loose wiring may cause unit

malfunction, the wires to burnout or the terminal to overheat and

catch fire. There is a risk of electric shock, physical injury or death.

• Use outdoor and waterproof connection cable rated up to 300V for

the connection between the indoor and outdoor unit to avoid electri-

cal shock, which may cause physical injury or death.

• Separately wire the high and low voltage lines to avoid damage to unit.

• Local codes may require field-installed disconnect switches from outdoor unit to indoor unit.

• Use heat-proof electrical wire capable of withstanding temperatures up to 167°F to avoid damage to unit.

• Always use a circuit breaker or time delay fuse when connecting electrical wiring to the unit.

• Ensure you connect the wire firmly. Loose wiring may cause unit malfunction, the wires to burnout or the terminal to overheat and catch fire.

There is a risk of equipment malfunction or property damage.

• Use outdoor and waterproof connection cable rated up to 300V for the connection between the indoor and outdoor unit to avoid damage to

the unit.

• Comply with local codes while running wire from the indoor unit to the outdoor unit.

•

Do not allow wire to touch refrigerant tubing, the compressor or any moving parts since it can lead to mechanical failure.
