cian. The requirements are: 117-volt, 60-Hz, 3-prong outlet
that provides a separate ground, separately fused at 15 amps,
and not controlled by a light switch.
Caution:
Do not use an extension cord to supply power to the control
unit.
1. Plug the power cord into the ac outlet. The green "Power" light in the upper left
corner of the control unit should be on; the red "Warning" light should come on
momentarily to show that it is working and then go off. If the green "Power" light
does not come on, check the outlet. If the outlet is working properly and the green
light remains off, call the HELP number (1-800-628-2888).
2. If the red "Warning" light does not light momentarily or if it remains on, call the
HELP number (1-800-628-2888).
