HIGH FLOW INSUFFLATION UNIT UHI-3
Insufficient gas supply
1.
When the bar graph for supply pressure lights only one green LED and the
alarm sounds (approximately 1 second): The remaining gas volume in the
cylinder may be insufficient. Replace with a new cylinder as outlined in
Section 3.3, “Connecting a CO
2
gas cylinder”.
2.
When the bar graph for supply pressure lights red and the alarm sounds
(approximately 3 seconds followed by 10 seconds of silence): The cylinder
valve may be closed or the cylinder may be empty. If the bar graph for
cylinder pressure still does not light green after the cylinder valve is opened,
replace the cylinder with a new one as outlined in Section 3.3, “Connecting
a CO
2
gas cylinder”.
3.
When the medical gas pipeline is connected, improper hose connection or
pressure reduction in the gas supply source may cause an alarm. Check the
hose for proper connection and check the gas supply source for normal
pressure.
