WARNING
: Compressor installation must be performed by a qualified electrician in accordance with the National
Electrical Code (NEC) or the Canadian Electrical Code (CEC), the National Electrical Safety Code (NESC) OSHA code, and/or
any local or state codes having precedence�
Be sure of proper wire sizing and that the circuit breaker and the distance from the breaker is within suggested range� Confirm your
electrical-supply voltage matches what is required for the motor�
!
WARNING
: The compressor must be grounded� Grounding reduces the risk of electric shock� 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�
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�
!
WARNING:
These units should not be rewired to change between 115/230v� This is because the solenoid is different and
will not work properly on the other voltage
!
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�
!
CAUTION
: Dry pipe sprinkler compressor must be wired to a reliable power source to be compliant with AHJ�
