Testing and Adjustments
Performance Verification
Use following test steps to verify manifold
system’s functional performance.
1. Remove manifold cover.
2. Before beginning test, verify the following:
• Both left and right side manifold master
valves are turned to full counterclockwise
open position.
• Master valve on high-pressure reserve
header is turned to full counterclockwise
open position.
• Liquid containers are attached to left side
of manifold and left bank contents gauge
indicates pressure greater than “Left
Secondary Supply Switch” setting. Refer
to Table 1, page 27.
• High-pressure cylinders are attached to
right bank of manifold and cylinder
contents pressure gauge indicates at least
1800 PSI (at least 600 PSI for Nitrous
Oxide or Carbon Dioxide).
• High-pressure cylinders are attached to
high-pressure reserve header and cylinder
contents pressure gauge indicates at least
1800 PSI (at least 600 PSI for Nitrous
Oxide or Carbon Dioxide).
• Power is applied to manifold.
3. If manifold is not in use, close 3/4" source
shut-off valve.
4. Verify two right-side line regulator isolation
valves are open and two left-side line regulator
isolation valves are closed.
5. Verify the following:
• Only left bank green "IN USE" and right
bank yellow "READY" lights are
illuminated.
• Red “RESERVE IN USE” and “RESERVE
LOW” lights on power supply box are
NOT illuminated.
• If manifold is connected to a master alarm
panel, “SECONDARY SUPPLY”,
“RESERVE IN USE” and “RESERVE
LOW” alarms are NOT activated.
6. If manifold is equipped with a dome regulator,
verify dome regulator’s gauge reads 40-45
PSI. If manifold does not have a dome
regulator, proceed to next step.
7. Open vent valve to create a small flow of gas
through manifold. Vent valve must be opened
wide enough so that left side bank regulator
gauge (attached to left dome regulator body)
just begins to slightly drop.
8. Verify that pressure gauge reading on left side
bank regulator is as indicated in Table 1
(intermediate pressure - in use bank). If
pressure is not correct, refer to Bank
Regulator Adjustment procedure.
WARNING:
If necessary, most service, adjustment, and
testing can be performed while manifold is in
service. However, this should only be done by
qualified technicians experienced in servicing
medical equipment. Servicing and testing
manifold while not in use, with 3/4" source shut-
off valve closed, is preferred. Following test
procedure assumes that manifold is not in
service.
NOTE:
Dome regulator’s red locking ring must be pulled
out away from regulator body before adjustment
knob can be turned. After adjustment, push
locking ring inward to lock knob. Since dome
regulator is self-relieving, it is recommended that
dome regulator always be increased to desired
pressure. For example, if dome regulator
pressure is too high, first lower pressure to
approximately 30 PSI. Then raise pressure to
between 40-45 PSI.
