Electrical – Line Voltage
All field installed wiring, including electrical ground, must
comply with the National Electrical Code as well as all
applicable local codes.
Refer to the unit wiring diagrams for fuse sizes and a
schematic of the field connections which must be made
by the installing (or electrical) contractor.
Consult the unit wiring diagram located on the inside of the
compressor access panel to ensure proper electrical hookup.
All final electrical connections must be made with a
length of flexible conduit to minimize vibration and sound
transmission to the building.
208 Volt Operation -
All 208-230 Volt units are factory
wired for 208 Volt. The transformers may be switched to
230V operation as illustrated on the wiring diagram. By
switching the Red (230V) and the Orange (208V) at the
contactor terminal L2.
