Have a generator that does not appear to be functioning properly?
Please follow these instructions:

Check to be sure the electricity to the generator is correct.
Check the circuit breaker and reset if necessary.
Check the OPERATION INDICATOR light (if so equipped):
GREEN or Flashing GREEN: NORMAL
RED or Flashing RED: There is an internal problem; the generator must be reset. Follow the reset procedure as listed on the top of the generator. If generator Operation Light fails to return to Solid Green, the unit needs to be returned. See instructions in next paragraph.

After checking the above, if the unit still appears to be malfunctioning:

Call 800-446-8100 (toll free), 757-855-0191, or contact us;
Provide the serial number of the generator;
Explain the problem you are experiencing with the unit.
We will instruct you as to the procedures for handling the generator. Carefully pack and protect generator in a suitable box, if authorized, for return shipment.

CAUTION: Do not attempt to repair the generator! Repairs should only be made by authorized, trained personnel.

Please remember that these are expensive generators and, while in your possession, you are responsible for them. The generator is an expensive, complex piece of equipment. To alter it or change the composition of the ETHY-GEN^® II is very risky and unnecessary.

DO NOT TRANSFER OR RETURN GENERATORS WITHOUT FIRST CALLING.
