CARIB Approved IOM 12 - ARID Permeator AT-150 -VR-201-Z /VR-202-Z drawing number 9900-9945 in the Healy CAS portion of the CARB-Approved Installation, Operation and Maintenance (IOM) Manual is suitable for construction details to produce a new concrete pad suitable for installation of the PERMEATOR. Next, the PERMEATOR mounting stand is attached to the concrete pad with appropriate sized bolts and the use of a small hoist. Once secured in place, the aluminum lid is removed and the piping and electrical conduits and connections can be made. Since the main cabinet is rated for service in Class I, Division 1, Group C & D hazardous environments, this allows for the unit to be located in relatively close proximity to the manifold vent lines to avoid long piping runs. After all piping and wiring connections are completed, then the PERMEATOR aluminum lid can be attached and fastened in place. The doors are equipped with a lock and key. Site personnel should be aware of the storage spot for the key. Typically, a protective barrier(bollards) or fence is constructed to keep PERMEATOR out of view and to discourage vandalism. (In Luxembourg and Shikoku, Japan the units are mounted right on the island, adjacent to the dispensers). Contractors should check with local Fire and Safety authorities prior to installation to ensure that the location chosen meets all applicable Fire Marshal codes and regulations. Piping Layout and Installation ARID's PERMEATOR system requires three piping connections; one for feed flow from the combined storage tank vapor spaces to the membrane module, a second connection for returning rich vapors from the permeate side of the membrane to the vapor space of one of the low grade tanks, and a third connection for venting air discharged from the retentate side of the membrane to atmosphere. The PERMEATOR can be connected to existing piping configurations in various ways. Installation is easily accomplished in accordance with Figure 5. Other variations are possible and are outlined in Exhibit 2 of the VR-202 series of Executive Order(starting with Revision Y). Field experience shows that elevating the PERMEATOR approximately 3 feet above grade provides adequate slope in the interconnection piping to avoid liquid accumulation in either the feed or permeate lines. The pipe sizes used should be the same size as existing vent piping—typically 2"nominal ID minimum for US installations. All three piping ports on PERMEATOR are equipped with flanges to ease field connections. 9
