Introduction
The Amico Automatic Cryogenic Liquid Solenoid Manifold is designed to provide a reliable, uninterrupted supply of
gas to a hospital or other medical facility. The manifold accommodates multiple cryogenic containers divided into
two equal banks. One bank is designated as a “Primary” source of gas while the other bank stands in reserve as a
“Secondary” source.
A display of LED’s on the front of the manifold indicates the status of the gas supply. Each bank has a green (IN
USE), yellow (READY) and red (EMPTY) LED. When the primary bank of cylinders are depleted, the manifold will
automatically switch to the secondary bank of cylinders without interruption of gas flow to the facility. The red
LED will illuminate when a bank is depleted and two normally closed dry contacts for the reserve In-Use alarm
will open. One or both sets of contacts may be wired to an external alarm, remote buzzer and/or a building
management system.
When the empty Liquid tanks / Dewar’s are replaced with full ones, the manifold will need to be reset by pressing
the “PUSH TO RESET” button on the front of the cabinet. At this time the status is changed from EMPTY to READY
mode as indicated on the LED display that the bank is now the secondary bank.
Note: the “PUSH TO RESET” button should not be pressed until the empty Liquid tank / Dewar has been replaced
with a full one.
The power supply is connected to the top right hand corner of the manifold. Connections from the manifold to the
Amico master alarm must be made from terminals marked C/Signal to the appropriate terminals (Reserve In-Use) on
the master alarm or a remote buzzer.
The Manifold is designed in accordance with the National Fire Protection Association (NFPA 99)
FEATURES INCLUDE:
•
Input power to the manifold is 110-240 VAC, 50-60Hz
•
Incorporates six LED’s display - readable in poor lighting conditions
•
Dual line pressure regulators
•
•
3/4" Isolation valve for supply line
•
Manifold complies with NFPA 99
•

Description of the Manifold
SHIPMENT DETAILS
The Manifold system may be shipped in more than one carton, depending on the number of cylinder connections. The
main carton contains the following items:
•
•
•
•
Manifold control panel (with power supply assembly)
Wall mounting bracket (attached to manifold control panel)
3/4" (19.05mm) source shut-off valve
Installation, Operation and Service manual
Additional cartons may contain appropriate number of headers and cylinder pigtail assemblies. Cylinder inlets closest to
the manifold control panel are intended for cylinders placed directly beneath the manifold control panel. Pigtails for all
gases are 72" (1,828.8mm) flexible type. The manifold is designed to be mounted directly to a wall.
THE MANIFOLD ENCLOSURE
The manifold contains a switch mode power supply that can handle voltage from 110-240 VAC with a built-in fuse and
terminal block. The enclosure on this manifold is NEMA-1 (general purpose applications only). This cabinet must not be
mounted outdoors. For outdoor use, a NEMA- 4 enclosure is recommended.
The manifold also has a latched enclosure that is easy to remove. The pre-assembled circuit board is located on the
center of the enclosure with a hinged mounting bracket. This design will reduce installation time and eliminate the risk
of improper installation, since all the components of the manifold are connected and tested at the factory.
MANIFOLD DISPLAY BOARD
The LED’s on the front of the Manifold indicate the status of the gas supply. The primary bank will indicate (In-Use, with
the Green LED turned on) and the reserve / secondary indicating (Ready, with the Yellow LED turned on) or (Empty, Red
LED turned on) depending on the status of gas. When the primary bank of cylinders are depleted, the manifold will
automatically switch to the secondary bank of cylinders without interruption of gas flow to the facility. The Red LED
will illuminate when a bank is depleted and two normally closed dry contacts will open. One or both sets of contacts
may be wired to an external alarm, remote buzzer and/or a building management system.
When replacement cylinders are attached to the depleted bank and the reset button pressed, the red LED goes out and
the yellow LED illuminates indicating that the bank has been automatically designated as the secondary supply. No
other user interaction is required. Both sets of dry contacts close to cancel any external alarm conditions.
ECONOMIZER CIRCUIT
To prevent the loss of useful gas into the atmosphere, an economizer circuit is included to utilize the accumulated
excess pressure from the secondary supply bank. The economizer circuit re-routes the excess pressure into the line via
check valves inserted into the main inlet blocks, then passes through the 0.007" orifice which goes into the main center
section of the manifold.

Amico Corporation
Description of the Manifold
LIQUID TANKS
Liquid cylinders contain the product in a liquid state inside of the container. The liquid has to be converted to gas before
entering the manifold. This can be done by the container VIA the internal vaporizers, or in a high or low flow situation
with an external vaporizer. The contents of the liquid container can only be measured by weight. A gauge on the tank,
or simply rocking the tank to determine its weight. The contents of the tanks cannot be measured by the pressure
output. The gauges on the manifold for bank pressure do not indicate the amount of product inside the liquid tanks.
GAS FLOW THROUGH THE MANIFOLD
The liquid containers are divided into two banks. One bank will be the “In-Use” and the other bank will be “Ready” or
secondary bank. The bank In-Use can be either bank with the other bank as secondary, depending on the current status.
As the “In-Use” bank depletes (liquid is gone and pressure drops in that bank) the manifold will switch to the secondary
bank. Indicator LEDs will change to indicate the “In-Use” now as “Empty” and the “Ready” bank will become “In-Use”.
NOTE:
It is common for the pressure on the empty bank to increase and give the false indication that the tank is full. Always check
contents of tanks via weight and float gauge on the tank.
The “Empty” tank can then be replaced with a full one. The manifold will not reset until the “Empty” bank is replaced and the
“Push to Reset” button is pressed. At this time the status is changed from “Empty” to “Ready”. That bank is now the secondary
bank. The “Push to Test” reset should not be pressed until the empty tank has been replaced with a full one.
During normal operation this sequence of alternation will change, the “In-Use” and “Ready” banks from right hand to left
hand banks back and forth as tanks get depleted.
Depending on the amount of gas usage the pressure building valve on the tank “In-Use” may need to be left open. This
allows the tank to convert adequate liquid to gas for the higher flow needed. This will depend on the facility’s usage. This will
normally cause frosting on the outside of the container indicating the proper operation of the pressure builder. Occasional
venting of gas on the tank to relieve excessive pressure is normal and can be expected.
RESERVE (HIGH PRESSURE) BANK
The high pressure reserve bank is used to back up the liquid tanks. The reason is that sometimes the liquid tanks (both
banks) could run empty and the personnel using the system does not know how to determine the amount of liquid
content inside the tanks.
When the liquid tanks run empty, the pressure inside the manifold will drop (in the case of OXY, CO2 & N2O below 150
PSI and NIT below 275 PSI). At 80 PSI for OXY, CO2 & N2O and 180 PSI for NIT, the High Pressure Reserve manifold will
start to supply gas. An alarm from the Reserve In-Use pressure switch (set at 85 PSI for OXY, N2O & CO2 and 190 psi for
NIT) will be activated. The Reserve header has a reserve low pressure switch (to be set at 1100 PSI for OXY, NIT & AIR and
500 PSI for CO2 & N2O) that will ensure the Reserve Header has adequate volume to supply the facility until the liquid
tanks are replenished. The reserve high-pressure tank when full is usually around 2300 psi for OXY, NIT & AIR and 800
PSI for CO2 & N2O.

Description of the Manifold
RESERVE (HIGH PRESSURE) BANK
NOTE:
Flow capacity depends on the amount of liquid containers and type of tanks/containers used. For Oxygen the average
flow per liquid tank/container is 350scfh. Flow capacity is increased with additional containers. For higher flow
requirements an external vaporizer (supplied by others) is necessary.
Description of Parts
MAIN LINE SOURCE VALVE
A 3/4" (19.05mm) isolation valve with a locking handle, supplied with the manifold
should be installed on top of the manifold connecting to the main supply line.
SOLENOID VALVE
The Solenoid valve is 12 VDC, normally open and is located between the Liquid tank/
Dewar and the Line regulator. The Solenoid is logically controlled by the micro display
board with the bank In-Use being normally opened and the reserve/secondary being
held normally closed.
PRESSURE TRANSDUCERS
The Pressure Transducer senses the bank pressure and transfers information to
the display board to indicate the In-Use, Reserve & Empty mode. There are two
transducers in the manifold cabinet, one for the left bank cylinder and one for the
right bank cylinder.
CHECK VALVE
A Check valve is provided upstream of each solenoid to prevent back flow while
servicing a bank.

Description of Parts
LINE REGULATOR BALL VALVE
Quarter-turn ball valves are provided upstream and downstream of each
line regulator. These valves allow for removal and servicing of one of the
line regulators while the other is in use. All four ball valves are normally in
the open position.
DUAL LINE REGULATOR
On every Amico Automatic Gas Manifold the line regulator is capable
of maintaining a constant dynamic delivery of pressure at the
maximum designed flow rate of the system. For Oxygen, Nitrous
Oxide and Carbon Dioxide service, the line regulators are factory preset
at 55psi and for Nitrogen at 170psi.
PRESSURE RELIEF VALVE
Pressure relief valves are installed downstream of all pressure regulators
and are set at no more than 50% above the setting of the pressure
regulator. Relief valves are capable of fully relieving the pressure at
the set point. All pressure relief valves in the manifold have piping
connections to allow for connection of a vent line to the outside of
the facility.
FRONT PANEL INDICATORS
Six front panel indicators monitor the status of the manifold.

OPERATING ALARM SYSTEMS
The manifold control cabinet contains the required circuitry to send a dry contact signal to the alarm unit when
a bank is empty and change-over occurs. The normally closed internal circuitry is designed to alarm when there
is an open circuit. The depletion of a bank triggers a relay, which renders the alarm circuit open and initiates the
alarm signal.

Display Functions
1. Introduce power to the control cabinet
2. Follow Cylinder Changing Procedures on the side of the cabinet to ensure that all tanks and fittings are secure and
properly connected to the header bar.
3. Check the indicator LED for proper functioning.
4. Open the Liquid Tanks one side at a time and press the “Push to Reset” button between the LED displays. One Green
LED, on the side which had the tanks opened first should be lit for In Use and the other side should have a Yellow
LED lit for Ready.
5. Close the Liquid tank valves on the primary (In Use) bank and watch the indicator LED to ensure proper functioning.
The primary bank pressure should decrease, while the secondary and line pressures stay constant.
6. When the primary bank pressure falls to approximately 100psi for all gases except Nitrogen which is 200psi, the
bank switch-over occurs. The line pressure will remain constant with the LED illuminating, indicating the In Use and
Empty banks. After replacing the depleted gas cylinders, open the liquid tank valves on the depleted side and press
the “Push to Reset” button and the Empty bank should become Ready.
7. With the Manifold wired to the Amico Master Alarm, the change-over from primary to secondary bank will cause
an audible alarm. The appropriate indicator LED on the Master Alarm will illuminate. This can also be achieved by
usingthe switch-over test button located on the back of the control board.
The Amico Automatic Manifolds are designed in accordance with the current revision of NFPA 99.
There are two categories of the Amico Manifolds. Depending upon the delivery pressure, the following gas types
are available.
55psi Delivery Pressure
• Oxygen, Nitrous Oxide, Carbon Dioxide
170psi Delivery Pressure
• Nitrogen
NOTE:
In the event of a power fluctuation or failure, a switch over alarm will be activated on the master alarm panels.
• Both the solenoid valves will open and supply pressure until both the banks are depleted.
• The solenoid will not prevent the flow from being supplied no matter which side is In-Use and until the system is
completely out of gas.

Amico Corporation
Installation Precautions
Tampering with gas specific connections shall be prohibited. Do not alter, remove or modify gas specific connections.
Keep all manifold parts, tools and work surfaces free of oil, grease and dirt. These and other flammable materials may
ignite when exposed to high pressure oxygen or nitrous oxide.
•
Do not use chemicals, lubricants or sealants unless specified in these instructions
•
Before connecting the Liquid tank / Dewar to the manifold, ensure the tank valve is free of dirt and debris
•
After connecting the tank to manifold, open the tank valve S-L-O-W-L-Y to allow heat of compression to dissipate
•
Do not use flame or “sniff” tests for leaks
•
Do not apply heat to any part of the manifold system
•
Always ensure Liquid tanks / Dewar’s are secure and on level floor
•
Do not repeatedly bend, sharply bend, or twist pigtails as damage to tubing may occur
•
After the manifold wall bracket has been mounted, at least two people should lift and hang the manifold cabinet, one
should not do this alone
•
Do not put the manifold into operation until verified by a qualified person as per NFPA 99 or other local standards

Testing for Leaks
The following instructions apply for performing a leak test on the joints made during assembly and connection of
the Amico manifold.
The connections inside the Amico control cabinet have been inspected at the manufacturing plant and DO NOT
require leak testing. In order to determine whether any leaks exist between the tank and header bar sections or at
the pipeline connections, the systems must be pressurized using either oil-free dry air or oil-free dry nitrogen.
In the case of medical Oxygen, Nitrous Oxide, or Carbon Dioxide Amico manifolds, the actual service gases
ARE NOT suitable for leak testing due to their inherent dangerous properties. Leak testing must be performed
using either oil-free dry air or oil-free dry nitrogen.
•
Connect a Liquid tank of the manifold service gas to the header bars on each side of the manifold using the
proper tank connection hose assemblies (pigtails) supplied
•
Make sure all other outlets are capped with the plug and chain assemblies supplied
•
Make sure that the pressure inlet valves of each bank are fully OPEN
•
“S-L-O-W-L-Y” open the tank valves on each side of the cabinet, one side at a time, to pressurize the header bar and pipeline
•
All outlets from the pipeline, downstream of the manifold, should be closed and thus there should be no
flow from the manifold
•
Check for leaks at all tank extension joints and at the joints where the pipes are connected to the pipeline,
using a commercial leak detector which is compatible with oxygen
•
If any leaks are found the system must be depressurized by bleeding through a convenient pipeline outlet
and the faulty connections must be repaired
•
The Header bar connections may be tightened one more turn maintaining the horizontal location of the
tank adapters, or a further application of an oxygen service threaded sealant may be required
•
If the brazed pipeline connections leak they must be removed, cleaned and then re-brazed following the
proper technique. All repaired joints must be pressure tested as mentioned previously

Line Regulator Pressure Adjustment
This procedure should be performed if the line regulator pressure is not within acceptable limits during performance
verification procedure or after installation of a new line regulator.
1. With both the banks supplying pressure, open ball valves on the inlet and outlet on only one side of the line regulator
to be adjusted.
2. Slightly press the bleed valve on the side of the regulator to create a small flow of gas though the manifold.
3. Using the handle on the bonnet of the regulator, turn to adjust the pressure to the specified setting, as mentioned on
the cabinet door by observing the line gauge.
4. Repeat (steps 1-3) to adjust the other line regulator.
5. After adjusting the pressure to the specified setting open all balls valves and ensure the supply line remains open.
Line Regulator Replacement
If necessary, the line regulator replacement can be performed while manifold is in service. However, this should only be
done by qualified technicians experienced in servicing medical equipment.
1. Close the two ball valves on inlet and outlet of line regulator to be replaced.
2. Loosen union nuts on two closed isolation valves.
3. Vent pressure from the bank, which was shut off in step 2, by pressing the bleed valve on side of the regulator.
4. Ensure the orientation of fittings (direction of gas flow) is the same on the replacement regulator. Install fittings on new
regulator.
5. Inspect O-ring removed from the ball valve union. If damaged, replace O-ring.
6. Verify the correct orientation of fittings on the regulator; some slight adjustment may be required to align with the
ball valves without causing stress to the fittings.
7. Hand-tighten the two ball valve union nuts and then with a wrench snug lightly to ensure the fittings are secure.
NOTE: do not over tighten unions, as it is an o-ring seal.
8. Open ball valves and set the line regulator’s output pressure as described in Line Regulator Pressure Adjustment procedure.
