Connecting Outdoor Unit Power Wiring and

Communication / Connection (Power) Cable

1. Confirm that electrical power supply capacity will be sufficient to run the unit. Ver-

ify that a circuit breaker and service disconnect are installed. See the "Electrical

Specifications" in the "Product Data" section for details on electrical requirements.

Per code, install a main indoor breaker, and an outdoor service disconnect that interrupts

injury or death.

2. Confirm that the right gauge size is used for all wiring. Follow all federal, state,

and local codes related to power wiring to the outdoor unit. For specifications

related to communication / connection (power) cable from the outdoor unit to the

indoor unit, see the information detailed in this section.

3. HLV3 outdoor units have a side panel to protect the electrical components. Using

a Phillips head screwdriver, remove the four (4) screws, and guide the side panel

down and out as shown.

4. Inspect all interior wiring to be sure they are secure and have not loosen during

transportation and outdoor unit installation. Also, inspect wires for damage or

cracks.

Loose, damaged, or cracked wires will cause electric shock, bodily injury and / or death.

Loose wires can cause the wiring to burn out, damaging the outdoor unit.
