WARNING:
The compressor must be grounded. Grounding reduces the risk of electric shock. This product must be
connected to a grounded, metallic, permanent wiring system, or an equipment-grounding terminal or
lead on the product. Certain C-Aire models are equipped with a cord that has a grounding wire with a
grounding plug. The plug must be plugged into an outlet that is installed and grounded in accordance
with all local codes and ordinances.
WARNING:
Improper installation of the grounding plug will result in a risk of electric shock. When repair or
replacement of the cord or plug is required, do not connect the grounding wire to either flat-blade
terminal. The insulated wire with a green outer surface and yellow stripes is the grounding wire.
WARNING:
Duplex compressors: this product has more than one connection to the power supply. To reduce the risk of
electrical shock, disconnect all such connections before servicing.
NOTE:
The installation, electric motor, wiring, and all electrical controls must be in accordance with NFPA 70-1996 National
Electric Code, National Electric Safety Code, and state and local codes. Failure to abide by the national, state, and local
codes may result in physical harm and/or property damage.
DANGER:
High voltage may cause personal injury or death. Disconnect and lockout/tagout, per OSHA regulation
1910.147, all electrical power supplies before opening the electrical enclosure or servicing.
DANGER:
Never assume a compressor is safe to work on if it is not operating. It could restart at any time. Always
disconnect/lockout/tagout before servicing.
Magnetic Starter:
If the compressor is equipped with a magnetic starter, the starter must be installed in accordance with
the wiring diagrams in this manual.
Pressure Switch:
If the compressor is NOT equipped with a magnetic starter, refer to the wiring diagrams below.
