If you will install the unit on a wall-mounted bracket, do the following:
CAUTION
• Before installing a wall-mounted unit, make sure that the wall is made of solid brick, concrete, or of similarly strong
material. The wall must be able to support at least four times the weight of the unit.
• Mounting unit on brackets is at the discretion of the installing contractor - it must be fastened and secured prior to
operation.
NOTE
If allowed, you can install the wall-mounted unit with rubber gaskets to reduce vibrations and noise.
Step 4: Connect signal and power cables
The outside unit’s terminal block is protected by an electrical wiring cover on the side of the unit. A comprehensive
wiring diagram is printed on the inside of the wiring cover.
WARNING
All wiring must performed strictly in accordance with the wiring diagram located inside the outdoor units' wire cover.
1. Unscrew the electrical wiring cover and remove it.
2. Unscrew the cable clamp below the terminal block and place it to the side.
3. Match the wire colors/labels with the labels on the terminal block, and firmly screw the u-lug of each wire to its
corresponding terminal.
4. After checking to make sure every connection is secure, create a drip loop to prevent rain water from flowing into
the terminal.
5. Using the cable clamp, fasten the cable to the unit. Screw the cable clamp down tightly.
6. Terminate unused wires. Arrange them so that they do not touch any electrical or metal parts.
7. Replace the wire cover on the side of the unit, and screw it in place.
