1 Connect the non-copper
end of the hose to the
gas supply. Ensure that
there is no pressure
into the hose before
connecting it to the
console.
MORIA supplies a black hose (black is the international code for
nitrogen).
All questions regarding gas, gas bottles, or regulators should be
addressed to the gas supplier.
The hose is delivered with a copper quick connection on one end,
and free on the other end.
The free end has to be connected to your own gas supply system
(dry and ltered medical grade air or nitrogen bottle with its dual
stage gas regulator and male nozzle).
MORIA recommends using:
• a high-pressure dual stage regulator
• dry medical grade nitrogen gas, or dry and ltered medical
grade air to operate pneumatic turbines, available from your
medical gas supplier
MORIA does not supply the gas.
2 Connect the Nitrogen/
Air Hose (#19120) to the
control unit
B2, B3
D1, D2
3 Before opening the dry
medical grade nitrogen
gas tank, or dry and
ltered medical grade
air tank, always set the
pressure to the minimum
value by turning the
knurled blue knob (B1)
counterclockwise.
To operate the knurled blue knob (B1), pull it toward the back. B1
4 Pressurize the system
The pressure to the
generator should
be between 4 and 6
bars (58 and 87 psi).
Incoming pressure
must not exceed 14
bars.
If the pressure going IN the console exceeds 8 bars (116 psi),
the console detects excess pressure and opens the high
pressure valve. The dry medical grade nitrogen gas, or dry and
ltered medical grade air is ejected from the turbine connector
(front panel) in order to protect the internal components.
If so, have the system checked by MORIA.
5 Set the pressure in
the console by turning
the knob (B1) on the
rear panel to obtain a
pressure of 3.2 ± 0.2
bars (46 ± 3 psi)
Once the dry medical grade nitrogen gas tank, or dry and ltered
medical grade air tank is opened, increase the pressure to the
appropriate amount (3.2 bars):
• turn the knurled blue knob (B1) clockwise to increase
pressure
• turn the knurled blue knob (B1) counterclockwise to decrease
pressure.
Once the correct pressure has been selected, lock the knob (B1)
by pushing it.
Do not use the unit if LED (A16) or (A18) are ON.

the gasket is present and undamaged on the front panel of the
console and on the rear of the turbine.

to use.
Refer to user manual :
• CB, CBm, CBSU for LASIK: #65005
• CBm, CBSU for articial chamber : #65078
• ONE, One Use : #65009
Always check intraocular pressure with a tonometer (#19042) prior
to using any keratome.
