Continuous Duty Relay: The relay acts as a giant on/off switch that controls the high amperage to the
compressor. The relay is controlled by the toggle switch and for systems that include an air tank, a pressure
switch is on the same circuit (see wiring diagram). Only continuous duty relays of the correct amperage
capability can be used, not doing so will void your compressors warranty. The relay uses less than 5 amps to
energize and can be powered using 14-16 gauge wire for the switching post in most applications. Every
compressor installation must utilize a continuous duty relay, failure to do so will void your warranty.
