UCR INSTRUCTION MANUAL
Ch.3
The optional medical gas pipeline adapter (MAJ-1084 or MAJ-1085) is required for connection to the
medical gas pipeline.
DANGER
Using gases other than medical grade CO
2
may result in fire, poisoning,
complications, etc. In addition, oil, impurities, etc., may penetrate the interior of the
endoscopic CO
2
regulation unit and impede proper CO
2
gas insufflation.
CAUTION
• If the medical gas pipeline adapter is damaged, replace it with a new one.
• Connect the gas supply hose to the endoscopic CO
2
regulation unit before
connecting it to the CO
2
gas connector. Otherwise, there is a danger of significant
gas leakage.
• For proper insufflation of the CO
2
gas, confirm that the pressure of the medical gas
pipeline is more than 343.2 kPa (3.5 kgf/cm
2
) and below the upper limit given in
ISO 7396 (1400 kPa).
• Use MAJ-1084 for NIST type fittings, and MAJ-1085 for DISS type fittings. Do not
use any other hoses than those specified.
NOTE
Olympus does not sell medical gas pipeline hoses. Use an appropriate hose for the
medical gas pipeline being used.
The medical gas pipeline adapter must be attached to the endoscopic CO
2
regulation unit by Olympus
personnel during installation. The enclosed nut cover will be fixed during the installation when the
cylinder hose and the endoscopic CO
2
regulation unit are connected by Olympus personnel.
3.4 Connecting the medical gas pipeline adapter
(MAJ-1084, MAJ-1085)
1
Inspect the medical gas pipeline adapter for the endoscopic CO
2
regulation unit for
damage, cracks, and irregularities.
2
Set the gas source selection switch on the rear panel to the “Pipeline” mode.
3
Use the supplied wrench to attach the medical gas pipeline adapter for the
endoscopic CO
2
regulation unit to the CO
2
gas inlet on the rear panel of the
endoscopic CO
2
regulation unit and securely tighten it. Tighten with a force of about
24.5 N·m (2.5 kgf/m). (See Figure 3.1)
