Product Description

The Amico Medical Gas British Outlet is composed of two separated modules: the “Rough-in assembly” and the “Latch­valve assembly”.

The “Rough-in assembly” consists of a brass machined body that incorporates a spring loaded check assembly. A 12.7
mm OD, 9.52 mm ID copper pipe is sliver brazed into the body for external pipeline connections. The brass body and
pipe assembly are inserted into a gas specic plate. The “Rough-in assembly” has a colour 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” incorporated 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 specic 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 with a gas specic housing which accepts, retains and releases the probe,
indexed on the back side to match gas specic indexing of the “Rough-in assembly”.

CAUTION: DO NOT over tighten the Latch Valve mounting screws! Distortion of the Latch valve can occur.

Outlets are available for oxygen, medical air, surgical air, nitrous oxide, medical vacuum and anesthetic gas scavenging
system. These are designed in accordance with HTM 2022, BS EN 737-1:1998 and BS 737-4:1998 (for AGSS)

Cleaning and Lubrication

The Amico British 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, which is compatible with plastic.
Lubricate elastomer seals sparingly with silicone lubricant that is oxygen compatible. DO NOT USE OIL

Preventative Maintenance

Regular inspection and maintenance of the Outlets will prolong its life and reduce the possibility of sudden, inconvenient
component failures. The use of damaged probes or faulty equipment may require further maintenance.

Outlets should be subjected to regular inspection and testing as follows:

Monthly;

a. Visually inspect the Outlet for signs of damage.

b. Check to see if the Front Latch Assembly (2nd Fix) operates smoothly with the gas specic probe.

c. If there is any disagreement with the operation of the Front Latch Assembly (2nd Fix), remove the unit for

closer inspection/repair/replacement if necessary.

Annually;

a. Remove Trim Plate and clean debris from the mounting box.

b. Remove Front Latch Assembly (2nd x) and inspect the barrel for any damage.

c. Inspect the Rough-in Assembly (1st x) for any damage. If damage or leaking replace components.

d. Test Front Latch Assembly (2nd x) for correct operation (connection and disconnection of the probe) using a

blank probe.

1. Unscrew the two Trim Plate screws (1), and remove Trim Box Plate (2) and the Trim plate (3).

2. Unscrew the two Retaining screws (5) until the Latch Valve Assembly (4) can be removed from the Outlet.

3. Remove the two Retaining washer screws (11), and remove the Retaining washer (10).

4. Remove the gas connector (9)

5. Remove the Body Seal (6) and Poppet (7) from the front of the Gas Connector (9). Inspect the items for wear or
damage and replace the Body Seal (6).

6. Remove the Gas or Vacuum Spring (8, to inspect if wear id damage. Re-install the Gas or Vacuum Spring.

7. Re-install all internal components into the Gas Connector (9). Check that the Gas or Vacuum Spring (8), Body Seal
(6) and Poppet (7) are in place. Re-install the round Retaining washer (10) and secure with two Retaining washer
screws (11), do not over tighten.

8. Re-install the Latch Valve Assembly into the outlet. Coat the connector (9) with a thin coat of oxygen compatible
silicone lubricant to aid insertion. Tighten down the Retaining screws (5), DO NOT over tighten, as this could
damage the Latch Valve Assembly.

9. Re-install Trim Plate (3) and Trim Box Plate (2) and tighten down Trim Plate screws (1).

10. Connect gas specic adapter into the outlet. The connection should be smooth and the adapter should lock and
remain in place allowing gas to ow. If not, replace the entire Latch Valve Assembly (4).

1. Unscrew the two Trim Plate screws (1), and remove Trim Box Plate (2) and the Trim plate (3).

2. Unscrew the two Retaining screws (5) until the Latch Valve Assembly (4) can be removed for the Outlet.

3. After removing the Latch Valve Assembly (4) from the Outlet, you can then pull the Check Valve Body Assembly
from the back side of the Latch Valve Assembly (4). Remove the Check Valve Body Seal (10) and check for any
abnormal wear or Damage and Replace, coat the O-ring with a thin coat of oxygen compatible silicone lubricant.

4. Disassembly of the Check Valve Body Assembly: Hold the Check Valve Body Assembly in one hand, and push
down the Check Valve (6) with your thumb of the same hand, compressing the Check Valve Spring (9). Remove the
Check Valve O-ring (12). Release the Check Valve (6) slowly; the Check Valve Body Assembly will fall apart.

5. Reassembly of the Check Valve Body Assembly: Re-install the Check Valve Spring (9) onto the Check Valve
(6), and then insert them into the Check Valve Body (11). Again, hold the Check Valve Body Assembly in one
hand, and push down the Check Valve (6) with your thumb of the same hand, compressing the Check Valve Spring
(9). Before re-installing the Check Valve O-ring (12), coat the O-ring with a thin coat of oxygen compatible silicone
lubricant.

6. Insert the Check Valve Body Assembly into the back of the Latch Valve Assembly.

7. Re-install the Latch Valve Assembly into the outlet. Coat the outer portion of the Check Valve Body Assembly with a
thin coat of oxygen compatible silicone lubricant, to aid insertion. Tighten down Retaining Screws (5), DO NOT over
tighten, as this could damage the Latch Valve.

8. Re-install Trim Plate (3) and Trim Box Plate (2) and tighten down Trim Plate Screws (1).

9. Connect gas specic adapter into the outlet. The connection should thread in smooth and the adapter should

Rough In Assembly

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:

NOTE: Suction inlets (Vacuum and AGSS) are not supplied with Secondary Check Valves. The Secondary Check Valve (4)

and Secondary Check Valve Spring (5) are not required.

1. Ensure that no pressure exists in the line by depressing the secondary check (4).

2. Remove the retaining ring (1) from the inside of the outlet body. Use a small screwdriver to pull the end of the ring
toward the center and then pull the ring up and out.

3. Remove the washer (2), seat/seal (3), secondary check valve (4) and the secondary check valve spring (5). Inspect
items for wear or damage and replace the seat/seal (3).

4. Re-install the spring (5), secondary check valve (4), seat/seal (3) and the washer (2). Insert the retaining ring (1) 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 then inspection and
test.
