supply tank approximately 1 turn. Turn on the Power
Switch. Upon turn on, all lights and indicators will be illuminated for a brief
period.
2. The Gas Supply indicator should display red-yellow-green bars. The color
coding in the bar graph is a guide to determine whether there is sufficient gas in
a “D” or “E”

10.2 PREPARATION TEST
There is always the possibility that delicate equipment can be damaged in
transportation or storage. Therefore it is important to verify proper operation of the
unit before use.
1. After power is applied to the unit, verify that the front panel lights are enabled.
2. To verify that flow control is functioning properly, depress the FLOW
STOP/RUN button. When pressed, the light in the switch should light, and gas
may be heard exiting from the unit. If gas does not begin flowing, verify that the
CO
2
supply tank valve is in the open position (see section 10.1,
Power On and
Gas Supply Indicator
).
3. To prevent wasting gas in the Free Flow mode, when the FLOW STOP/RUN
button is pressed initially and after 150 Liters of CO
2
is continuously delivered,
the unit automatically returns to STOP mode. Thereafter, subsequent presses of
the FLOW STOP/RUN button will resume the delivery of CO
2
for an additional
150 Liters before automatically returning to STOP mode. To prevent wasting gas
in the Managed Flow mode, when the FLOW STOP/RUN button is pressed
initially and no changes in pressure have been detected for 10 minutes, the unit
automatically returns to STOP mode. However, you can stop the flow using the
FLOW STOP/RUN button while the unit is in RUN mode, as evidenced by the
illuminated FLOW STOP/RUN button.
4. If the unit does not perform properly, do not use. Inspect the unit using the
Troubleshooting Guide (Section 13.0) before returning for service.
