Section 3 Safety Checks
3.1
Final Connection Checklist
When all items have been installed, all hose connections
must be checked and tested.
The installer must ensure that all gas connections are
correctly made and leak free. The installation must conform
to NFPA 99C guidelines, as well as all local codes and
ordinances. For proper United States color coding, see
page 2.
WARNING
Route all hoses and cords so that there are no
obstructions, pinched or kinked hoses, or potential
abrasions of hoses and cords when the installations
complete.
NOTE
When all connections are complete, all gas stop valves
and hoses must be accessible for future maintenance
of the mixer and its components.
3.2
Cross Pipeline Tests
WARNING
Although this analgesia machine is designed to restrict
the interchanging of the two gases, it is the
responsibility of both the user and the installer to
determine that only oxygen flows into the oxygen fitting
and that only nitrous oxide flows into the nitrous oxide
fitting located at the rear of the mixer head.
If the gas pipeline test fails at any step, the pipeline
must be repaired and tested again, starting at step 1.
Before repair or testing, the entire system must be
purged of any residual gas. If repair is required, follow
the NFPA 99C code for brazing requirements; see the
Introduction.
1. Close the gas shutoff valves on the main supply
cylinders.
2. Exhaust the gas from the entire manifold and pipeline
system by sequentially connecting an indexed gas hose
to each outlet station or connection point.
WARNING
To prevent injury from hose whip, always hold the free
end of the hose.
3. Open the oxygen shutoff valve on the main cylinder
only.
4. Verify:
that oxygen gas flows at each oxygen outlet station
that no gas flows at each nitrous oxide outlet station
NOTE
Use only oxygen or nitrous oxide when testing gas
lines.
5. With the oxygen still pressurized, open the nitrous oxide
shutoff valve on the main cylinder.
6. Verify that nitrous oxide gas flows at each nitrous oxide
outlet station
3.3
Gas Outlet Station Tests
If additional gas outlet stations are installed, complete the
test procedures listed in the Matrx by Parker Outlet Stations
Installation and Parts Manual.
3.4
Mixer Tests
Complete the performance checks listed in section 3.1 of
the Digital MDM® Operations Manual (Part No. 10545100).
