HIGH FLOW INSUFFLATION UNIT UHI-3
3.3
Connecting a CO
2
gas cylinder
Using other gases than medical grade CO
2
may result in fire,
poisoning, complications, etc. In addition, oil, impurities, etc.,
may penetrate the interior of the UHI-3 and impede proper
CO
2
gas insufflation.
• Always keep the gas cylinder in the upright position. Fasten
the cylinder to a wall or another stable structure to prevent it
from toppling. If the gas cylinder is placed horizontally or in
an inclined position, liquefied CO
2
may enter the insufflation
channel inside the UHI-3 and normal insufflation may
become impossible.
• Only open the CO
2
gas cylinder valve after correctly
connecting the UHI-3 and the CO
2
gas cylinder. Opening the
CO
2
gas cylinder valve before correctly connecting the
equipment will result in liquid CO
2
flowing into the cylinder
hose. The insufflation channels inside the UHI-3 may freeze
and prevent proper CO
2
gas insufflation.
• Never lubricate the equipment/hose connections with grease,
oil, etc. This could result in grease, oil, or other foreign matter
penetrating into the UHI-3, impeding proper operation and
preventing proper insufflation of CO
2
gas.
• Olympus is not liable for any injury or damage due to
improper cylinder connection.
• If a significant gas leak is noted from within the UHI-3,
terminate its use immediately and contact Olympus.
