Fully open the main valve controlling the water supply to the Model DDX Deluge Valve. Lower air pressure allows for smaller capacity, lower cost dehydration equipment, where required. Flanged-End Connections Flange Dimensions (Inlet & Outlet) 8” AMSE (200mm) B16. A system low air pressure switch, which is used to monitor sprinkler piping. System air pressure — Verify that system’s air pressure and water supply pressures are in conformance with the values posted in Table A. The introduction of moisture into the system piping exposed to freezing temperatures can create ice blockage, which could prevent proper system operation. Reliable Technical Bulletins 337 and 338 provide information for maintaining the Model DDX Deluge Valve. thereby causing the air compressor to continuously cycle on and off. Note: The Model DDX-LP DryPaK is available with its air compressor wired for a 120 VAC/60Hz or 220VAC/ 50 Hz power supply. The trim set used with the Model DDX-LP Dry Pipe Valve contains the Reliable Model LP Dry Valve Actuator releasing device. Prior to opening valve P, be sure that the Model B1 Accelerator has been successfully reset per Reliable Technical Bulletin 323. 5 Class 150 Bolt Bolt Hole Flange Flange Number Circle Diameter Outside thickness of Bolts Diameter Diameter 11¾” (298mm) 7/8” (22mm) 13½” (343mm) 1” (25. Adjustment, if required, should be made according to System Sensor Bulletin A05-0177 included with the switch. The dew point of the air supply must be maintained below the lowest ambient temperature to which the dry system will be exposed. As a minimum, the supply of air should be taken from the area of lowest temperature within the protected area. When using the Reliable DDX-LP DryPaK the sprinkler system is pressurized (supervised) with air provided by the optional factory-installed air compressor (or on-site Nitrogen supply) and is monitored by a system pressure switch. System maintenance is simplified since priming water is not required and the Dry Pipe Valve can be reset externally without cover removal. Visually verify by the position of its indicator flag that it is fully-opened.
