Resumen del manual
• Follow all safety codes. • Wear safety glasses and work gloves. • Use care in handling and installing this accessory. WARNING To avoid the possibility of electrical shock, open and tag alldisconnects before installing this equipment. Failure to doso could result in severe personal injury. INTRODUCTION An accessory long line check valve must be installed for: 1. Any 025-030 size dual circuit unit where the evaporator is located higher than the condensing unit and thelinear line length exceeds 55 ft (16.8 m). 2. Any size dual or single circuit unit with linear linelength of 100 ft (30.5 m) or more. ACCESSORY USAGE CAUTION For all units with liquid lines of 100 ft (30.5 m) or more orany 025-030 size dual circuit unit application where evapo- rator is located higher than the condensing unit and liquidlines exceed 55 feet (16.8 m), a long line check valve mustbe installed to prevent compressor failure. The long linecheck valve accessory must be mounted in the liquid lineas close as possible to the condensing unit. The long line check valve accessory must be mounted in theliquid line near the condensing unit. The valve is brazed intothe liquid line. Fitting adapters may be required to connect thecheck valve to the liquid line. The valve may be mounted inany orientation, horizontally or vertically. See Fig. 1 for dimen- sions. Figure 2 shows the location of the check valves on arooftop installation. Figure 3 shows the location of the checkvalves on a ground level installation. UNIT SIZE CIRCUIT TYPE CHECK VALVE SIZE (in.
