GFCI RECEPTACLE TESTING AND RESET- TING PROCEDURE

The GFCI receptacle should be properly tested at least once every month or whenever it is tripped. To properly test and reset the GFCI receptacle:

•If the receptacle 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 recep- tacle. This will assure normal GFCI operation.

•Plug a night-light (with an "ON/OFF" switch) or other product (such as a lamp) into the GFCI receptacle and turn the product "ON".

•Push the "Test" button located on the GFCI recepta- cle. 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" button is pushed, the GFCI is not working prop- erly or has been incorrectly installed (miswired). If your GFCI is not working properly, contact a qualified, certified electrician who can assess the situation, rewire the GFCI if necessary or replace the device.
