Abrégé

An apparatus for calibration and testing of pressure switches which are used in residential and commercial HVAC systems. The apparatus can be used to test, set, or adjust a pressure switch or a pressure signal transducer to the manufacturer's specifications. The apparatus includes an exterior housing with an on/off switch and at least one vacuum inlet nozzle, and the inside of the housing includes an air compressor to which the amount of voltage supplied can be manually controlled. The air compressor typically operates from a battery power supply located within the housing. A pressure measuring device, such as a differential pressure gage, and a conductivity indicator are typically used in conjunction with the device to calibrate adjustable pressure switches and to test and diagnose faulty pressure switches. The apparatus can include the pressure measuring device and/or the conductivity indicator within its housing.

Abrégé

A device to clear a blockage from an HVACR condensate drain line. A piston connected to a rod with a handle is inserted directly into the distal or outlet end of a condensate drain pipe and then rapidly withdrawn to create a vacuum or suction within the drain line. When sufficient suction pressure is created, it will dislodge a blockage in the drain line. Typically the piston has a proximal end with a diameter slightly greater than the inside diameter of the condensate drain pipe. Upon removal of the device from the drain pipe, the proximal end is caused to expand to its full diameter, creating an airtight and fluid tight seal with the inner diameter of the drain pipe, allowing for the creation of negative pressure and/or suction upstream to dislodge the blockage.

An apparatus for calibration and testing of pressure switches which are typically used in residential and commercial HVAC systems. The apparatus can be used to test, set or adjust a pressure switch to the manufacturer's specifications. The apparatus includes an exterior housing with an on/off switch, two vacuum nozzles, and a bypass control valve mounted thereon, with the inside of the housing including an air compressor in communication with the nozzles and the bypass control valve. The air compressor typically operates from a battery power supply located within the housing. A pressure measuring device, such as a differential pressure gage, and a conductivity indicator are typically used in conjunction with the device to calibrate adjustable pressure switches and to test and diagnose faulty pressure switches. The apparatus can be constructed as a compact, hand-held instrument for use in an HVAC service environment, and can include the pressure measuring device and/or the conductivity indicator within its housing.
