Notes:
1. Operating voltage is the min and max voltage for which the unit can function. Never
operate outside of this min and max voltage.
2. The Acceptable Performance Range is the min and max voltage for which the unit
performance is designed and rated to give acceptable performance.
Route power and control wiring, separately,
through the utility entry in the base of the
unit. Do not run power and control signal
wires in the same conduit. The utility entry is
located in the unit base in the front right hand
corner of the unit (compressor compartment).
See unit drawing for specific location.
