7.2 Connecting the cables

The power wiring should always follow NEC and local codes, with respect to the unit’s, rating plate. See installation manual for additional information. Main power connection is 208/230V/1PH~60HZ.

The communicating cable, which connects between the indoor and outdoor units must meet all NEC and local codes, with respect to the unit’s rating plate. We recommend using 14 AWG/4 conductor Stranded THHN 6 Ф Ф V cable.

NOTES:

Capacity test is based on standard length and maximum allowance length is based on reliability.

Oil trap should be installed per (3-5 meters)10-15ft.

Outdoor connections are ¼” (Ф6.35 mm) liquid and 3/8” (Ф9.52 mm) gas, therefore a reducer is provided with all 12/18k indoor sections.
