SECTION 2: CIRCUIT REQUIREMENTS

220/440V Operation

Serious personal injury could occur if you connect the machine to the power source before you have completed the setup pro- cess. DO NOT connect the machine to the power source until instructed after setup.

Electrocution or fire could result if this machine is not installed to code. You MUST ensure compliance by checking with a quali- fied electrician!

NOTICE

The Model G0646/G0647 is prewired for 220V operation. If you plan to use your machine at 440V, you MUST have a quali- fied electrician perform the 440V conver- sion described on Page 13.

NOTICE

Extension Cords (220V Only)

Using extension cords may reduce the life of the motor. Instead, place the machine near a power source. If you must use an extension cord:

•Use at least a 12 gauge cord that does not exceed 50 feet in length.

•Ensure that the extension cord contains a ground wire and plug pin.
