    Section 1: Safety Warnings Section 1: Safety Warnings Please read the following safety warnings carefully before installing the equipment. 1.1 Introduction This section is meant to communicate to the user any hazards involved with the equipment. The following paragraphs will define the hazard warnings used and describe the icons found in various sections of the manual and on the equipment.
  • Page 11 1.1.2 Hazard Types (Symbols) This symbol is a safety alert symbol. This symbol represents asphyxiant, toxic or corrosive gases. Gases used with the Gasguard 250 can cause personal injury or death. This symbol can represent one or more of the following...
  • Page 12: Inert Gas Hazards

    Section 1: Safety Warnings This symbol represents electrical shock hazard. This symbol warns of potential strain or injury when lifting cylinders. This symbol warns of a pinch hazard. This hazard exists on cabinet doors equipped with automatic closers. This symbol warns of the possibility of the cabinet tipping over if it is not installed properly.

  • Page 16: Section 2: Dimensions And Mounting

    Section 2: Dimensions and Mounting 2.1 Outline Dimensions The Gasguard 250 Valve Manifold Boxes are typically mounted to a free-standing floor mounted rack. An alternate wall mounting method utilizes vertical unistrut attached to the rear of the enclosure. Figure 2.1 shows the outline dimensions for an eight branch valve manifold box with unistrut for wall mounting.

    250 VMB System Installation Manual 2.2 Mounting Hole Locations The Gasguard 250 Valve Manifold Box rack assembly is mounted to the floor using the four (4) 3/8" holes located in each corner of the rack. See Figure 2.3 for typical mounting hole locations for the 4 and 8 branch VMB racks. The mounting location should be clean and level.
  • Page 20: Section 3: Tubing Connections

    Section 3: Tubing Connections Section 3: Tubing Connections All tubing should be designed and installed following the local piping codes and the following: • ASME B31.3 "Chemical Plant and Petroleum Refinery Piping" • SEMC-005 "UHP Tubing and Fitting Specification" (found in the Appendix) Tubing must be sized to flow the maximum amount of gas required by the process system.

  • Page 22: Process Line Connection

    Section 3: Tubing Connections 3.2 Process Line Connection The process line connection is designed to use a 1/2" stainless steel outer jacket which can be attached to a coaxial tee supplied at the valve manifold box. This outer jacket is either pressurized with nitrogen at a pressure above that of the process line and monitored with a pressure switch, or purged with nitrogen into an exhaust system which contains gas detection devices.
  • Page 23: Vent Line

    Air Products and Chemicals, Inc. Page 3 - 4...
  • Page 24 Section 3: Tubing Connections When multiple gases are to be vented, ensure compatibility before plumbing vents together. Contact your Air Products Representative for this information. A nitrogen trickle purge is constantly bled into the vent line through the vacuum venturi assembly to maintain an inert atmosphere and prevent back diffusion through the vent system.
  • Page 25: Venturi Line

    Gasguard 250 VMB System Installation Manual 3.4 Venturi Line Air Products strongly recommends a separate venturi supply source rather than a houseline source. Most process cylinder pressures are significantly higher than houseline operating pressures. In the event of multiple failures of certain process panel components, there is a remote possibility of back contamination of the houseline source connected to the vacuum venturi.
  • Page 26: Pneumatic Supply

    Section 3: Tubing Connections 3.6 Pneumatic Supply A nitrogen (or compressed clean dry air) source is required for pneumatic valve operation. This nitrogen supply needs to be regulated to 75-95 psig (100 psig maximum allowable working pressure). The flow rate required for pneumatic valve operation is negligible.
  • Page 27: Enclosure Exhaust System Requirements

    If these steps are not followed, the controller must be purged by the times stated on the label attached to the controller. Figure 3.5: Rear View of Gasguard 250 Controller 3.7 Enclosure Exhaust System Requirements The VMB enclosure must be connected to an exhaust system that is capable of meeting the following criteria: 1.
  • Page 28 Section 3: Tubing Connections 3. In silane service, an air velocity of 200 feet per minute must be achieved across all unwelded fittings per UFC Article 80, Section 8004.1.18, 1994 edition. The table below lists the exhaust requirement for GG250 VMB Enclosures to meet the above requirements.
  • Page 29: Weld Shield Gas, Purge Gas Connection

    100 psig should be used on the high pressure inert gas supply. A safety relief device set at 150 psig should be installed downstream of the pressure regulator. Air Products and Chemicals, Inc. Page 3 - 10...
  • Page 30: Helium Leak Test Port

    Section 3: Tubing Connections 3.9 Helium Leak Test Port (Optional) An optional helium leak test port may be provided on the vent header for connection to a helium mass spectrometer. Two manual valves are included in the assembly; MV-31 isolates the helium leak test port, and MV-32 isolates the downstream vacuum venturi/vent system to achieve vacuums required for inboard leak testing upstream.
  • Page 31: Section 4: Electrical Connections

    Section 4: Electrical Connections Section 4: Electrical Connections All electrical connections must comply with Article 300 - Wiring Methods and Article 500 - Hazardous (Classified) Locations of the National Electric Code (NEC) 1993. Reference to the use of this equipment in Hazardous Locations only applies to installations located within the United States of America.
