Amico Medical Gas Outlet British Standard Compatible Installation Guide

Medical Gas Outlet British Standard Compatible
Installation Guide

Product Description

The Amico Medical Gas British Outlet is composed of two separate modules: the “Rough-in Assembly” and the “Latch Valve Assembly”.
The “Rough-in Assembly” consists of a brass machined body that incorporates a spring loaded check assembly except for Vacuum and AGSS. A 12.7 mm OD, 9.52 mm ID copper pipe is SILVER brazed into the body for external pipeline connections. The brass body and pipe assembly are inserted into a gas specific plate. The “Rough-in Assembly” has a color coded label on the front plate and 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. Vacuum and AGSS rough-ins include a pressure plug for testing and servicing purposes. The “Rough-in Assembly” has a DUAL pin gas specific indexing arrangement to prevent the wrong “Latch Valve assembly” from being plugged into the “Rough-in Assembly” (see page 18).
The “Latch Valve Assembly” is manufactured with a gas specific housing which accepts, retains and releases the probe, indexed on the back side to match gas specific 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 02-01 and ISO 9170.

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 specific 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
d. Remove Trim Plate and clean debris from the mounting box.
e. Remove Front Latch Assembly (2nd Fix) and inspect the barrel for any damage.
f. Inspect the Rough-in Assembly (1stFix) for any damage. If damaged or leaking, replace components.
g. Test Front Latch Assembly (2nd Fix) for correct operation (connection and disconnection of the probe) using a blank probe.

Rough-in Assembly

CAUTION: Ensure that the supply pressure is shut off before performing service.
Inside the “Rough-in Assembly” is a secondary check valve whose function is to shut off gas flow 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.
