GFCI TESTING AND RESETTING PROCEDURE

The GFCI should be properly tested at least once every month or
whenever it is tripped. To properly test and reset the GFCI:
• If the GFCI has tripped, first carefully remove any load and
check it for damage.
• If the equipment has been shut down, it must be restarted.
• The equipment needs to be operating at high idle speed and
any necessary adjustments made on the control panel so that
the equipment is providing at least 80 volts to the receptacle
input terminals.
• The circuit breaker for this receptacle must not be tripped.
Reset if necessary.
• Push the "Reset" button located on the GFCI. This will assure
normal GFCI operation.
• Plug a night-light (with an "ON/OFF" switch) or other product
(such as a lamp) into the Duplex receptacle and turn the prod-
uct "ON".
• Push the "Test" button located on the GFCI. The night-light or
other product should go "OFF".
• Push the "Reset" button, again. The light or other product
should go "ON" again.
If the light or other product remains "ON" when the "Test" but-
ton is pushed, the GFCI is not working properly or has been
incorrectly installed (miswired). If your GFCI is not working prop-
erly, contact a qualified, certified electrician who can assess the
situation, rewire the GFCI if necessary or replace the device.
