0A (zero amps) on the Hose Zone Display.
o If the FTS is disconnected or the display shows E04, turn the main disconnect off, then

(zero amps) will show in the actual display with the hose zone off.
o When in the target mode of the hose heat zone, amperage can be adjusted from 20A to
45A with the up and down arrow keys.
o To prevent hose overheating, install a thermometer close to the gun end, within the
operators view. Insert thermometer through foam insulation cover of the "A" component
hose so stem is next to the inner tube. Thermometer reading will be approximately 20°F
less than the actual fluid temperature. It the thermometer reading exceeds 160°F (71°C),
reduce the current with the down arrow key.
o Thermometer reading should never exceed 160°F (71°C). Never leave the
machine unattended while in a manual current control mode.
