D. Electrical
A qualified electrician in compliance with standards and local codes should do all electrical
wiring. Be sure to investigate local requirements before installing the compressor. Refer to
the wiring diagram before starting any work.
The power supply should be adequate and free of parasitic loads that may cause a low
voltage condition during the operation of the compressor; otherwise, there may be nuisance
electrical shutdowns. This equipment requires a properly grounded electrical disconnect
switch.
We recommend the use of time delay fuses in a fusible disconnect for isolating the unit. This
disconnect should be located so an operator can disconnect the unit without being near the unit
in case of an emergency. We also recommend the use of a lockout/tagout to help insure safety
during maintenance of the compressor. Per the National Electric Code the time delay fuses
should be sized at 175% of the full load amperage (FLA) found on the motor nameplate.
Consult the Code if you want to use another style of branch circuit protection.
All internal wiring has been done at the factory. Wiring of the power supply to the
compressor should be done by a qualified electrician to comply with the National
Electric Code, state code, and any local codes in accordance with the wiring
diagram specific to your compressor model shown in the included wire diagram.
