The Amico Medical Gas outlet is composed of two separate modules: the “Rough-in assembly” and the “Latch-valve
assembly”. The “Rough-in assembly” is the same for all types (DISS, Ohmeda, Chemetron, Puritan-Bennett or Oxequip/
MedStar), while the “Latch-valve assembly” determines what type of adapter the outlet will accept.
The “Rough-in assembly” consists of a brass machined body that incorporates a spring loaded check assembly. A 1/2”
OD copper pipe is silver brazed into the body for external pipeline connections. The brass body and pipe assembly are
inserted into a gas specic plate. The wall outlets can be ganged together at 5” [127mm] centers (see page 5). This makes
for a nished assembly that looks like one complete panel of outlets. The “Rough-in assembly “has a color coded label
on the front plate and the copper pipe, so that the installer can easily identify the gas that the copper pipe should be
connected to. The “Rough-in assembly” incorporates a check valve that allows the “Latch valve assembly” to be removed
for service, without requiring the pipeline to be shut down. The “Rough-in assembly” has a DUAL pin gas specic indexing
arrangement to prevent the wrong “Latch valve assembly” from being plugged into the “Rough-in assembly” (see page
17).
The “Latch-valve assembly” is manufactured in ve dierent models: DISS, Quick connect Ohmeda compatible, Quick
connect Chemetron compatible, Quick connect Puritan-Bennett compatible or Quick connect Oxequip/MedStar
compatible. The DISS “Latch-valve assembly” is permanently riveted together, so that the gas specic components cannot
be taken apart, to ensure they remain gas specic. All the servicing on the DISS outlet is done inside the connector. On the
Quick connect models the connector plate can be removed for additional O-ring servicing, but is still gas specic since the
gas specic parts are permanently riveted together. The “Latch-valve assembly” consists of: a connector with an integral
check valve, an indexing block complete with indexing pins, a color coded gas front plate and a chrome frame. The “Latchvalve assembly” is inserted into the “Rough-in assembly” and secured screws.
CAUTION: DO NOT overtighten the Latch Valve Mounting screws! Distortion of the Latch valve can occur.
The quick connect models are compatible with the Ohmeda Diamond, the Oxequip/MedStar, the Chemetron, and the
Puritan-Bennett quick connect adapters. Only the corresponding type of adapters can be used with the quick connect
outlets. The DISS outlet conforms to the CGA Pamphlet V-5 standards. Since the “Rough-in assembly” is the same for all
models of “Latch-valve assemblies”, the outlet can easily be converted from one type to another by simply replacing the
“Latch-valve assembly”.

Cleaning and Lubricating
The Amico Outlets are factory cleaned for oxygen service. Exposed surfaces of the outlet may be cleaned with a mild
detergent solution or wiped with a disinfectant commonly used in patient rooms, that is compatible with plastics,
anodized aluminium and die cast zinc. Lubricate elastomer seals sparingly with a silicone lubricant that is oxygen
compatible. DO NOT USE OIL.
Inspection and Testing
Medical Gas Outlets should be inspected periodically or at least once a year. The test should be in accordance with NFPA
99 “Gas and Vacuum systems” .
Test for Leaks:
Ensure that no leaks exists, with or without the adapter inserted.
Test for Indexing:
Only a mating gas specic adapter should insert smoothly into the outlet, latch and be retained.
Test for Flow:
• Gas Outlets: 120 l/min (4.2 scfm) @ 345 kPa (50 psi), maximum allowable pressure drop is 28 kPa (4 psi).
• Nitrogen Outlet: 400 l/min (14.1 scfm) @ 1,250 kPa (180 psi), maximum allowable pressure drop is 70 kPa (10
psi).
• Vacuum Outlet: 30 l/min (1.1 scfm) @ 54 kPa (16 inHg), maximum allowable pressure drop is 13 kPa (4 inHg).
Refer to the appropriate standards for the proper way of performing the ow test.
Note:
The Amico medical gas and vacuum outlets meet and exceed these requirements at the time of manufacture.
However piping source capacity, sizing and restrictions may prevent outlets from attaining these values.

On all outlets (wall and console) the connecting pipe can swivel a full 360 deg. for easy connection to the gas pipe.
When soldering the pipe connection take care not to heat up the body, since that could damage the secondary check
valve.
It is very important to keep the protective cover (wall outlets only) in place during construction, to ensure that no debris
or dirt get into the outlet.
When installing the “Latch-valve assembly”, remove the protective cover and inspect for dirt or debris in the outlet body.
Clean out the contaminants, if required.
The “Latch-valve assembly” should slide in smoothly into the “Rough-In assembly”, if not, check that there is no damages to
the indexing pin arrangements. If the indexing pins are bent or damaged, replace the “Latch-valve assembly”.
DO NOT PRESSURE TEST THE PIPELINE OVER 100 PSI [690 kPa] IF THE “LATCH-VALVE ASSEMBLY” HAS BEEN
INSTALLED.
All “Rough-in assemblies” can be pressure tested up to a maximum of 200psi without the “Latch-valve assembly” attached
to it.
All “Latch-valve assemblies” with the exception of Nitrogen DISS have a Maximum pressure rating of 100 PSI [690 kPa]. The
Nitrogen D I S S has a maximum pressure rating of 200 psi [1,380 kPa].
After installation, perform the test on page 1.

Service
Before performing any maintenance on the Outlet, the appropriate hospital maintenance or engineering personnel
should be notied. The “Latch-valve assembly” can be removed without interrupting the service, but when servicing
the “Rough-In assembly” the supply pressure has to be shut o.

CAUTION: Ensure that the supply pressure is shut o before performing service.
Inside the “Rough-in assembly” is a secondary check valve whose function is to shut o gas ow when the “Latch-valve
assembly” is removed. This seat/seal also prevents leakage around the latch valve connector. As the secondary seal
is only a static seal, it will rarely need replacement. However, if the seat/seal does need replacement, follow the following
procedure:
1. Ensure that no pressure exists in the line by depressing the secondary check valve (5).
2. Remove the retaining ring (8) from the inside of the outlet body. Use a small screwdriver to pull the end of the
ring towards the center and then pull the ring up and out.
3. Remove the washer (7), seat/seal (6), secondary check valve (5) and secondary check valve spring (4). Inspect
items for wear or damage and replace the seat/seal (6).
4. Re-install the spring (4), secondary check valve (5), seat/seal (6) and the washer (7). Insert the retaining ring (8)
into the slot and ensure that the whole ring is seated properly.
5. Turn on the pressure and check for leaks. Re-install the “Latch Valve assembly” and perform the inspection and
test on page 1.
