MANUAL
COMPLETELY
Before Operating This Device
Basic delivery technique is described. Also, this manual contains instructions on periodically required checks to be
performed by the user. These checks are necessary to ensure the proper performance of this device and its safety
features. Retain this manual for future reference.
WARNINGS AND PRECAUTIONS
These warnings and precautions are to help you to
understand how to safely operate the Digital MDM Mixer.
A WARNING alerts you to a possible hazard to people. A
CAUTION alerts you to the possibility of equipment
damage.
WARNING:
Do not use this device for the administration
of general anesthesia or as a part of, or in conjunction
with, a general anesthesia administration system.
WARNING:
Use scavenging. Workers are exposed to

conscious sedation
analgesia. Exposure should be minimized. Time
Weighted Average (TWA) for Australia is 25ppm (parts
per million). Refer to SDS (Safety Data Sheet) for Medical
Nitrous Oxide.
WARNING:
The Digital MDM Mixer utilizes the
cross+protection
system. The flexible hose and
connectors that connect to the flowmeter are diameter
indexed; 3/8” O.D.for Nitrous Oxide and ½” for Oxygen.
The
cross+protection
system is designed to prevent
misconnection of Oxygen and Nitrous Oxide piping.
DO
NOT ATTEMPT TO CHANGE THE DIAMETERS OR
CONNECTORS OF THE FLOWMETER!
Tampering with
the
cross+protection
system constitutes acceptance of
liability by the installer. For your own protection, as well
as that of the Doctor and the patients,
use 3/8” O.D. tubing
for all Nitrous Oxide lines and ½” O.D. tubing for all
Oxygen lines.
To ensure safe operation and conformation to local fire
codes, all Digital MDM Mixer systems are designed to be
used with sedation delivery systems mounted inside walls
and they meet or exceed the guidelines established by the
National Fire Protection Association for Nonflammable
Medical Gas Systems, NFPA 99.
WARNING:
During any power outage, remember to turn
OFF the flowmeter and manually turn OFF the cylinder
valves. With centralized, electrically powered gas
systems, if gas was flowing when the power went out and
the flowmeter is left ON, gas will be flowing when the
power is restored.
CAUTION:
This device is intended to be used by medical
personnel trained in its use and the use of nitrous oxide
and oxygen for medical applications.
CAUTION:
Always use clean, dry medical grade gases.
Introduction of moisture or other contaminants into this
device may result in defective operation.
CAUTION:
Do not attempt to repair, alter or calibrate this
device. Unauthorized repair, alteration or misuse of this
device is likely to adversely affect the performance and
will void the warranty.
CAUTION:
Never oil or grease any part of this system
(minimize fire or explosion potential). Cylinder mount: Do
not clean check valve entrance or sealing washer (replace
as needed) with disinfectant.
CAUTION:
The user is responsible to choose how to
provide a cylinder valve clear of dust or dirt (which may
be carried to regulator and cause damage or accident).
One technique is “crack” [secure] cylinder valve before
installing cylinder to E-Block. Open valve slightly and then
close. Do not discharge flow of gas at any person or
flammable material.
WARNING:
New or modified installations -
properly
connected gas pipelines are absolutely essential to
patient safety.
The authorized distributor or contractor
should provide written documentation that all gas
pipelines are connected properly, and that the system has
been pressure tested prior to use. While this is a good
business practice, it is important that the user verify by
their own test, independent of the authorized distributor or
contractor, that all gas pipelines are connected correctly
prior to using the system.
The ultimate responsibility of
assuring that lines are not crossed rests with the
user.
