WELCOME: Con ratulations on your purchase of the world’s smallest office
Liquid Nitro en Generator the Elan2di ital. Bein the latest eneration
of award winnin Liquid Nitro en enerators offered by MMR, the
Elan2di ital boasts increased production rates, a smaller foot print,
quieter operation, and a di ital microprocessor.
The Elan2di ital offers a new user friendly interface; includin self-
mana ement and error checkin to improve overall efficiency, uptime, and
production. By minimizin user intervention, and with the provision of intelli ent
feedback and control, the Elan2di ital will offer years of quiet, clean, on-hand Liquid
Nitro en produced directly in your office.
INTENDED USE: The Elan2di ital systems are intended for indoor use only where clean
Liquid Nitro en is needed. Because the Liquid Nitro en enerated does not et
handled by complex industrial processes or trucks, it is extremely clean. This makes it
an ideal solution for research applications, clean rooms, tissue biolo ical sample
preservation, or clinical cryosur ical applications.
PRODUCT OVERVIEW: The Elan2di ital produces Liquid Nitro en strai ht from the air
direct to the user in their office. This is made possible by advanced Nitro en
separation and closed-cycle Kleemenko cooler technolo y. When put to ether a
production rate of 6-8Liters of hi h purity, clean Liquid Nitro en is possible. The new
built in self-mana ement system provides peace of mind that the Elan2di ital is
always performin at its peak, and Liquid Nitro en is always available on-demand and
on-time.
The system is comprised of:
Air Compressor unit with Dryer (PSA)
Elan2Di ital Liquefier Unit

LIQUID NITROGEN SAFETY: These liquid nitro en enerators have been desi ned with the
hi hest level of user safety in mind. They are also desi ned to minimize direct handlin
of Liquid Nitro en by the user. However care must be taken to ensure no contact is
made with the cryo enic fluid durin Liquid Nitro en removal from a leak or splash.
HANDLING: Never allow any unprotected part of the body to touch un-insulated pipes or
vessels which contain cryo enic fluids. The extremely cold fluid can cause severe burns
if even momentary contact with human skin is made. Always wear adequate eye
protection and loves when handlin cryo ens.
CONTAINMENT: Never carry Liquid Nitro en in a vessel not properly suited for Cryo enic
Fluids. MMR assumes no liability for injuries caused throu h improper handlin or use
of the provided Cryo en Stora e Vessels. MMR have thorou hly tested and approved
the followin Cryo enic Stora e Vessels for use with this system:
Brymill CRY-AC® Series for cryosur ery.
MVE Dewar’s from PrincetonCryo.
RIS OF EXPLOSION : NEVER CAP OR SEAL A STORAGE VESSEL FOR LIQUID
NITROGEN THAT DOES NOT HAVE ADEQUATE VENTILATION HOLES OR A PRESSURE RELIEF
DEVICE.
SPECIFICATIONS: Liquid Nitro en is a colorless, odorless, extremely cold liquid and as
(-198°C). It can cause rapid suffocation when concentrations are sufficient to reduce
oxy en levels below 19.5%. Contact with liquid or cold vapors can cause severe
frostbite. Cold vapors in the air will appear as a white fo due to condensation of
moisture. While this may indicate the presence of the as it should not be used to
determine its concentration in the atmosphere. Oxy en concentrations must be
monitored in the release area. All cryo enic liquids produce lar e volumes of as when
they vaporize. One volume of Liquid Nitro en will expand to produce 696.5 equivalent
volumes of as.
MSDS-OSHA: Not established.
ACGIH: Simple Asphyxiate.
CAS NUMBER: 7727-37-9.

CHOOSING A LOCATION: To ensure optimal operation and on oin performance of the
unit, the followin uidelines must be met:
Room temperature should not exceed 25 C (77 F).
Well ventilated.
The room should be free of dust and exhaust from other instrumentation.
The room should be of low humidity (<70% Rel Humidity).
A stable dedicated power source (Extension cords should be avoided).
HANDLING:
Never tilt or tip the unit.
Never move or JAR the unit when runnin .
Never block or obstruct the vents; doin so will overheat the unit and in some
cases cause permanent dama e. Temperature recordin devices have been
implemented for warranty purposes.

Quick Setup
CONNECTING THE AIR COMPRESSOR TO THE LIQUEFIER:
1. Connect Air Hose from Air Compressor to Liquefier. Hand ti hten only.
2. Connect Air Compressor Data cable to Liquefier and Air Compressor.
3. Connect both power leads from Air Compressor and Liquefier to suitable wall
outlets.
4. Turn on Air Compressor and Liquefier.
5. Switch the device to ‘Run’ 11
SETTING THE CLOC (IF NECESSARY): The clock is factory set, and is displayed when the
unit powers up, followed by the day. Press ‘Reset ’13 to view the clock at any time.
See pa e 8 if the time or date are incorrect. The clock is used for automatic
maintenance, which takes place at 9PM every Saturday ni ht.
TESTING THE AIR SUPPLY: With the unit runnin , press and hold the ‘Test Air Pressure’
button 14 on the rear of the unit. Over a period of 30 seconds, the ‘Pressure’ 10
should rise to a minimum of 90psi. If it doesn’t reach 90psi, check the air hose
connections for leaks.
DEFROST: Each time the unit starts up followin installation, a power failure, or resettin of
the unit, a 90 minute defrost is commenced. This can be cancelled at any time by
pressin the ‘Defrost’ button 8 on the front panel. Subsequent defrosts can be
started if required by pressin and holdin the ‘Defrost’ button for 2-3 seconds.
VIEWING SENSOR VALUES: When the system is not defrostin pressin the ‘Mode’ button
6 will to le the sensor value as indicated by the li hts 1
COOLDOWN: Once defrostin has completed, the refri eration system will become active
and will be in to cool down the liquefier. This can be monitored by watchin the
“Cryo Temp”. See Viewing Sensor Values. When the Temp has reached 77K, cool
down is complete and production will be in. This should take about 30 minutes.
LOC ING AND UNLOC ING: The ‘Lock’ feature 9 is a security device to stop unwanted
dispensin . If the unit is unlocked and the Dewar is in place, dispensin is enabled
indicated by the ‘Ready’ li ht 2. To unlock the unit, first hold down the ‘Lock’ button
9. While holdin the ‘Lock’ button, press and hold the ‘Mode’ button 6
simultaneously until the lock li ht oes out. To relock, simply hold the ‘Lock’ button 9
until the lock li ht comes on. Note: When locked, the unit will produce internally and
stay in the Dewar; it will maintain a full level in the liquefier until the device is
unlocked Unlocking can only take place in normal operation

LIQUEFIER TEMPERATURE: The liquefier temperature is shown either by selectin the
‘CRYO TEMP’ sensor value or by viewin the Temperature li ht 3.
When the temperature is reater than 77K production is not possible.
Flashing Red: Temperature is reater than 200K
Solid Red: Temperature is reater than 100K
Solid Blue: Temperature is less than 100K
LIQUEFIER LEVEL AND DISPENSES: The four li hts 4 show the internal level of the
liquefier. If no dispenses are made the unit will enter standby mode. Dispenses can
be made into the portable Dewar at any time by pressin and holdin the ‘Dispense’
button 7.
Durin dispensin if the “Dispense’ button is released or the Dewar removed the
Dispense will be cancelled to avoid dan erous Liquid Nitro en spills. The internal
liquefier is capable of holdin 1.2Liters of Liquid Nitro en, when emptied 4 hours
will be necessary before it is completely full a ain.
Flashin sequential li hts indicate the unit is in Standby 11.
SETTING THE CLOC : Each time the unit starts up after a power failure or the ‘Reset’
button 15 bein pressed, the time is displayed followed by the day. The day is
desi nated by a number (SUN=1, MON=2, TUE=3, WED=4, THURS=5, FRI=6, SAT=7).
To set the clock, press and hold the ‘Mode’ button 6 and ‘Transfer’ button 7
to ether, then press but do not hold ‘Reset’ 15. Continue to hold ‘Mode’ and
‘Transfer’ buttons until CLC
