Ensure the amber current limit light above termi-

As the hose reaches temperature, the O1 out-
put light will flicker less until it goes out com-
pletely. As this occurs, the amber light will flicker
off slowly, and then the green light will flicker off
slowly.
If you have a true RMS AC current meter, you can
check one of the hose cables for 45 amps AC +/-
2a. while the O1 output light is steadily on.
•
Check voltage at lower hose circuit breaker
between two hose cables. Keep in mind that
voltage varies with hose length; approximately
15 Vac per 50 ft. of 3/8 in. bundle plus 2.5V for
whip hose.
