500 Series Modular
Quick-Connect Features

Specifications

Medical Gas Outlet Stations shall be modular, Quick-Connect type. Modular outlet stations shall be field-assembled with sequence and services indicated on the plans. Centerline spacing of multiple outlets shall be 5 inches minimum.

Outlet stations for medical gases shall have a stainless steel faceplate mounted on a chrome-plated, zinc die-cast cover plate. The cover plate assembly shall contain the quick-connect latch release mechanism, indexing pins for safety keying the gas-specific cover plate to the appropriate rough-in box, and color-coded gas service identification. The safety-keying index pins shall be permanently captured between the cover plate and latch assembly. Designs with index pins molded in plastic will not be acceptable.

The latch mechanism shall be designed for one-handed, single thrust mounting and one-handed fingertip release of secondary equipment. The outlet stations shall be capable of supporting common secondary equipment, including suction regulator and half-gallon collection bottle, without the use of slide brackets.

The cover plate shall attach to the primary valve assembly. The primary valve shall be threaded into the rough-in box separately from the cover plate to facilitate leak-testing around the valve. Designs which prevent this test will not be acceptable. The primary valve body shall be made of brass and shall be adjustable to compensate for variation in plaster thickness.

Provide an o-ring within the valve to seal mating adapter plugs. Future replacement of this o-ring shall not require disassembly of the cover plate. The primary valve poppet shall be self-sealing in service, requiring no dust cap or cover.

The rough-in box shall be made of corrosion resistant, zinc plated, sheet steel with provisions for field-ganging by the installer. Provide two, factory-started, slotted, hex-head screws and fasteners with each rough-in box. Installer may gang rough-in boxes using holes provided for 1/8" diameter pop rivets.

Each rough-in box shall contain a base and tube assembly consisting of a Type K copper pigtail, flared to accept 1/4" ID, 3/8 " OD supply line, brass block and base housing a secondary check valve per NFPA 99 (not required in vacuum), primary valve o-ring seal, check valve inflator spring (except vacuum ), pressure testing cap plug, and plaster shield. The copper inlet tube shall be capable of rotating 360° to adjust for field piping conditions.

The secondary check valve shall be fully automatic and self-sealing upon removal of the primary valve. The primary valve seal shall be field replaceable WITHOUT shutting off gas supply to the outlet station. Designs that preclude servicing the primary valve seal in this manner will not be acceptable.

Medical gas outlets shall be cleaned for oxygen service in accordance with CGA Pamphlet G-4.1. The assembly shall be capped and internal parts poly-bagged for shipment. The outlet assembly shall bear the label of listing under Re-examination Service of Underwriter’s Laboratory

Quick — Connect Features

Specifications

Medical Gas Outlet Stations shall be Modular, D.I.S.S. type. Modular outlet stations shall be field-assembled with sequences and services indicated on the plans. Centerline spacing of multiple outlets shall be 5 inches minimum.

Outlet stations for medical gases shall have a stainless steel faceplate mounted on a chrome-plated, zinc die-cast cover plate. The cover plate assembly shall contain indexing pins for safety keying the gas-specific cover plate to the appropriate rough-in box. The safety-keying index pins shall be permanently captured between the cover plate and index pin retainer. Designs with index pins molded in plastic will not be acceptable. Provide a color-coded, molded plastic gas service identification label on each cover plate.

The outlet stations shall be capable of supporting common secondary equipment, including suction regulator and half-gallon collection bottle, without the use of slide brackets.

The cover plate shall attach to the primary valve assembly and rough-in box. The primary D.I.S.S. valve shall be independently safety-keyed to prevent cross-connection. In addition, the D.I.S.S. valve shall thread into the rough-in box separately from the cover plate to facilitate leak-testing around the valve. Designs which prevent this test will not be acceptable. The primary valve shall be made of brass, chrome plated, and shall contain a poppet that is self-sealing in service. The primary valve shall be adjustable to compensate for variations in plaster thickness.

The rough-in box shall be made of corrosion-resistant, zinc plated sheet steel with provisions for field-ganging multiple outlets by the installer. Provide two, factory-started, slotted, hex-head screws and fasteners and each rough in box. Installer may gang rough-in boxes using holes provided for 1/8" diameter pop rivets.

Each rough-in box shall contain a base and tube assembly consisting of a Type K copper pigtail, flared to accept 1/4" ID, 3/8" OD supply line, brass block and base housing a secondary check valve per NFPA 99C (not required in vacuum), primary valve o-ring seal, check valve deflator spring (except vacuum), pressure testing cap plug, and plaster shield. The copper inlet tube shall be capable of rotating 360° to adjust for field piping conditions.

The secondary check valve shall be fully automatic and self-sealing upon removal of the primary valve. The primary valve seal shall be field replaceable WITHOUT shutting off gas supply to the outlet station. Designs that preclude servicing the primary valve seal in this manner will not be acceptable.

Medical gas outlets shall be cleaned for oxygen service in accordance with CGA Pamphlet G-4.1. The assembly shall be capped and internal parts vacuum packed for shipment. The outlet assembly shall bear the label of listing under Re-examination Service of Underwriter’s Laboratory.
