CARB Approved IOM 12 - ARID Permeator AT-150 - VR-201-Z / VR-202-Z System Applications The PERMEATOR AT-150 is designed to accommodate a wide range of refueling station throughputs. Individual fueling points are not a factor in sizing PERMEATOR. Exhibit 2 of the VR-202 series Executive Order(starting with Revision Y) outlines installation parameters that must be followed for correct implementation of the PERMEATOR AT-150 at California GDF installations. A standard purchased AT-150 unit includes the following hardware: Main cabinet housing membrane module, vacuum pump, pressure sensor/transmitter, oil level sensor, vacuum sensor/transmitter and interconnection piping. The flanged connections provided are DN50, or 2" on each of the three connection points for Feed, Exhaust and Return lines. Electrical control cabinet including plc, cumulative run time meter, manual/auto/off switch, indicator lights, and main power switch Optional equipment: Upgrade kit for data logging of critical parameters such as tank pressure and run time readings and to allow electrical control panel to communicate with computers. Component Selection and Location AT-150 Control Panel operates and monitors the PERMEATOR system operation. Any anomalies of system operation will cause indicator lights to signal refueling station operating personnel that something is wrong. The panel is factory wired and assembled. Field wiring tasks include connecting 3 phase power from the site (L1, L2, L3 and Ground) and sensor input wires from the pressure and vacuum sensors/transmitters and the oil level sensor. The electrical panel is designed for use in a ZONE FREE area, mounted indoors. The electrical panel is typically mounted within the station kiosk adjacent to existing electrical panels and switching gear. The panel should be mounted so that the panel meter is vertical (please refer to Figure 2). Prior to connecting site power to the unit, sensor input wires should be connected in accordance with detailed instructions provided within the electrical panel (Please reference the "Quick Start Guide" found in the Appendix). Also, once these connections are made, a current loop test must be carried out and correctly verified before attaching main power supply leads and switching main power switch on. Mounting of PERMEATOR is quickly and easily accomplished at or slightly above grade. First, a suitable concrete support pad is poured and cured. This pad should be level, because the oil level sensor will not function properly if the pad is not flat and level. In California, if the PERMEATOR is replacing an existing Franklin Fueling Systems (Healy)vertical or horizontal Clean Air Separator(CAS), that concrete mounting pad is suitable for installation of the PERMEATOR provided that installation distances called out in Exhibit 2 are met. If the existing CAS mounting pad is not in a location that permits usage and a new pad needs to be poured,the specifications in 8
