With four ports and a built-in vacuum gauge on the SMAN4 digital manifold, users can evacuate a system, pull a vacuum, add refrigerant, and dial in the charge without unhooking their manifold. There are three standard ¼-inch ports and one beefy 3/8-inch port with the bore in the manifold being 3/8 inch throughout. The manifold receives live indoor wet bulb (WB) and outdoor dry bulb (DB) temperatures wirelessly, and then calculates real-time target superheat and digitally displays both the target superheat and the actual superheat on the large, backlit display. The SMAN4 can also wirelessly send six measurements (indoor WB, outdoor DB, suction line temperature, suction line pressure, liquid line temperature, and liquid line pressure) to the HVAC Guide® System Analyzer, Model HG3. The HG3 then combines the SMAN4 superheat and subcooling with airflow tests to take a snapshot of the entire system in real time. Other manifold features include high and low alarms for micron levels, two-point pressure calibration, large digital backlit display, and front-facing hose seats to limit dirt and grime from entering the manifold. Included with the SMAN4 are two ATC1 K-type pipe clamp thermocouples, ATWB1 WB thermocouple with clip, ATA1 DB thermocouple with clip, and an ANC10 padded drawstring pouch.
