摘要： An access device for installation to a condensation drainage system, such as a drain line of an HVAC unit, includes a main body with connecting ports at opposite ends for sealed, fluid flow inline connection to the drainage system. A top cover releasably secures to the main body to completely cover and seal an open top and interior cavity. A cleanout adapter has a flange that surrounds a bottom opening. The flange includes a seal around its outer periphery and is structured for sliding receipt within either of two transverse slots within the interior cavity to position the bottom opening of the adapter in sealed alignment with either of the connection ports, whereby a pressurized gas or liquid flow source, or a vacuum source can be connected to a top opening of the adapter for clearing a clog in the drain line either upstream or downstream of the access device.

摘要： A foot operated pump includes a water and airtight flexible and collapsible wall between a top plate and a base plate and an interior variable volume chamber. A flexible hose is selectively attachable to either an inlet port or an outlet port on the top plate member. The contents (air and/or liquid) within the variable volume chamber are forced out of the outlet port upon forced downward movement of the top plate member towards the base plate member. As the top plate member returns to a normally relaxed state in separated, angled relation to the base plate, the variable volume chamber enlarges and air is sucked through the inlet port to fill the variable volume chamber. An opposite end of the flexible hose attaches to various adapters and fittings for clearing clogged drain lines and other conduits.

摘要： A hose attachment device for use in combination with a source of pressurized gas or liquid for clearing HVACR drain lines. The device includes a cap having an interior cavity extending from an open bottom end that is sized for engaged receipt of an open-ended drain line extension. One embodiment of the device includes a hose extending through the top of the cap and having a fitting at the proximal end of the hose (extending from the top of the cap) that is sized for attachment to the pressurized source. A valve fitting at the distal end of the hose is sized for engaged receipt of a male valve stem, such as a Schrader valve. Another embodiment of the invention includes a valve fitting extending through top of the cap. A further embodiment of the invention includes an upper component and a lower component forming the cap, wherein the upper component is securable to a nozzle of a garden hose and the bottom component is securable to an open-ended drain line extension.

摘要： A mounting device for removably supporting an overflow safety switch in operable position within a condensation collecting drain pan in HVACR equipment. The mounting device includes a clip member that is secured to the drain pan side wall and locked in place by a non-penetrating thumb screw. A bracket removably attaches to the overflow safety switch at several adjusted positions and is slidably adjustable on the clip member for adjustably positioning the overflow safety switch relative to a bottom of the drain pan. The overflow safety switch is easily removed from the bracket for adjustment and replacement while the bracket remains fitted to the clip member. Moreover, the bracket is easily removed from the clip member without removing the clip member from the drain pan side wall.

A top cover releasably secures to the main body to completely cover the open top. An overflow safety switch is removably held in operable position within the interior cavity and below the top cover. The switch senses the level of condensate liquid accumulating with the interior cavity and sends an electronic signal to disable the condensation producing equipment if the liquid reaches a predetermined level.

摘要： A drain line valve device is provided for flushing HVACR drain lines. The device includes a main valve body having inlet and outlet connection ports on opposite ends for inline installation to a drain line (between the condensation producing source and drain discharge). The device includes a removable top cover and an adapter that is sized and configured for insertion into the interior cavity of the main body and fitted receipt within the inside of one of the input or outlet ports. The adapter allows for connection of a pressurized gas or liquid flow source for clearing clogs in the drain line, or a vacuum source, as well as pouring of a liquid clog-cleaning product into the drain line. One embodiment of the device includes a main valve body having one connection port for connection with an auxiliary outlet of a drain pan. An overflow safety switch is supported by the top cover in the interior cavity of the main valve body for detecting a clog in the drain line.
