Abstract: A condensate sensor enclosure to house an electromechanical control system to limit the level of condensate within a drain pan of an air conditioning system comprising a control system compartment and cover coupled together by a coupling assembly including a first coupler and a second coupler to enclose the electromechanical control system therein and a pair of probe housings each extending downwardly from the bottom of the control system compartment to operatively receive and house at least a portion a corresponding pair of electrically conductive sensor probes operatively coupled to the electromechanical control system to sense when the condensate within the drain pan reaches a predetermined level.

Abstract: A fluid-sensing switch system that can monitor pre-established threshold fluid levels in the primary drain pan inside an air conditioning unit or other condensate-producing unit, and also in a secondary drain pan positioned under the unit. Once the threaded plug of a sensing probe is connected to the unit's weep hole, it positions a center sensor providing a first power potential through a false-trigger-reducing resilient piece in a position to wait for rising fluid capable of breaching a weep hole dam. A substantially circular sensor is also present provides the second power potential needed for signal generation. A signal-generating member connected to both sensors is electrically connected to the unit to shut it off, and/or activate a pump that removes fluid from the secondary drain pan. The signal-generating member provides the redundant safety alarm capability, when mounted on a secondary drain pan. Anti-microbial elements are optional, but preferred.

Abstract: An alarm system for a storage hot water heater comprising an alarm housing, power supply leads inserted through the top of a hot water heater tank, a fluid collection pan positioned under the tank, and a fluid detection sensor associated with the pan. The alarm housing is configured to provide prompt owner/operator notification after only a small amount of fluid is collected in the pan under the tank. Owner/operator notification can be provided via audible, visual, and/or remote means, such as but not limited to a signal transmitted to a home security device that is relayed to a 24-hour security monitoring network. Since the alarm housing is hard wired, reliance on batteries is avoided and the system's useful life meets or exceeds that of the associated hot water heater. In addition, the leads never have to be removed from the hot water heater tank and can be made tamper-resistant.

Abstract: A generally mushroom-shaped vibration isolator having a broad cap and a smaller diameter stem that is used for safety enhancement between a heavy furnace, air conditioning unit, storage hot water heater tank, or other fluid-producing unit, and a fluid-collecting pan positioned under it. Vibration isolator stems are placed within indentations in raised areas of the pan and comprise highly impact-resistant materials, temperature-resistant materials, provide enhanced air movement and heat deflection around a furnace/unit/tank, reduce after-installation furnace/unit/tank movement, and meet furnace non-combustible clearance requirements. The cap has a broad underside surface, top surface radially-extending ribs and cutouts, and may have a slightly convex top, while the stem has at least one outwardly-depending wedge-shaped projection that is sufficiently flared-out to flip over as it is inserted into an indentation for a tight fit within several sizes of indentation, as well as removal resistance.

Abstract: A furnace riser block configured for placement under residential or commercial furnaces and having a generally isosceles trapezoid configuration when viewed from any of its four sides. It is made from strong and lightweight plastic materials that absorb vibration. At least two riser blocks are used together to support a furnace, each having a bottom flange, four corner protrusions, two side protrusions offset from a central location, a deep draft on all four of its sides, a high width-to-height ratio, vertical ribbing that creates a scalloped configuration and increases its vertical loading capability, and multiple indentations in its top surface each configured for receiving a metal jacket riser member that gives an additional inch of clearance when needed in an installation and/or receipt of a vibration isolator. The furnace riser block is stronger, lighter in weight, and safer to handle and ship, than known furnace supports made from metal material.

Abstract: A water detection assembly having an electronic fluid-sensing probe located in-line within a primary drain line associated with a fluid-producing unit via probe connection to an access port used for clearing and removing clog-causing debris from the primary drain line. The probe has no moving parts and quick-disconnect connection to a signal-generating unit. The access port is configured for vertical or horizontal installation and introduction of chemicals to clean the drain without retrograde backflow into the fluid-producing unit. The probe is inserted into the access port through a longitudinal opening when vertically installed, and alternatively through a lateral opening in a horizontal installation. When the probe detects fluid, the connected signal-generating unit sends an electronic signal that shuts off fluid production, activates an alarm or pump, and/or provides remote notification.

Abstract: A device attached to a fluid-level sensing probe used in association with the primary drain pan located inside an air conditioning unit or other condensate-producing unit, which provides quick testing for proper sensing probe function without its removal from the condensate-producing unit. A tester can simply press a different finger against each of two electrically-conductive rods attached to an inverted U-shaped mount that is typically fixed to the upper perimeter edge of a secondary drain pan positioned underneath at least a portion of the condensate-producing unit. If the sensing probe is properly functioning, the tester will immediately know, as a circuit will be completed and the condensate-producing unit will be shut off and/or a pump activated to assist removal of collected condensate from the secondary drain pan. For user convenience, an optional quick disconnect can be provided between the sensing probe and the inverted U-shaped mount.

Abstract: A fluid-sensing switch system that can monitor pre-established threshold fluid levels in the primary drain pan inside an air conditioning unit or other condensate-producing unit, and also in a secondary drain pan positioned under the unit, providing redundant safety response capability. Once the threaded plug of a sensing probe is connected to the unit's weep hole, it positions a center sensor extending through a false-trigger-reducing resilient piece in a position to wait for rising fluid capable of breaching a weep hole dam. The center sensor provides a first power potential, while a circular sensor also present provides the second power potential needed for signal generation. A signal-generating member connected to both sensors is electrically connected to the unit to shut it off, and/or activate a pump that removes fluid from the secondary drain pan. When mounted on a secondary drain pan, the signal-generating member provides the redundant safety response capability.

Abstract: A multi-level fluid-collecting pan configured for placement under an upright cylindrical hot water heater tank and support thereof. It has a circular bottom surface integral with a raised central hub, multiple raised arcuate spokes extending outwardly from the hub, and multiple elevated risers extending from the perimeter wall toward the hub. A perimeter wall around the bottom surface defines a non-raised fluid-collecting area. Vibration isolators that support a hot water heater tank upon the risers maintain the tank above any accumulated water in the non-raised areas of the bottom surface. Low elevation risers in perpendicular orientation to some risers, a nesting configuration with mismatched indents, sturdy and impact-resistant materials, a drain opening in the perimeter wall, and an upturned lip extending upwardly from the perimeter wall, are also preferred. The hub, spokes, and risers cover much of the pan's bottom surface and force accumulated water toward the perimeter wall.

Abstract: A two-piece clamping assembly with an integral rail plate used to rapidly and securely mount a float switch within a fluid collection container for fluid level monitoring. It is usable with both metal and plastic condensate collection pans, and successfully accommodates their differing wall thickness dimensions and different upper edge configurations. When its front and back clamping members are joined together over the top edge, lip, or flange of a pan using one centrally located top fastener, and at least one additional fastener is inserted through the back clamping member until it engages the exterior surface of the pan, the pan's upper edge becomes secured within an inverted J-shaped slot formed between the two clamping members. Vertically-extending internal ribs and horizontally-extending projections strengthen the clamping assembly. Preferred plastic materials also make the clamping assembly impervious to corrosion.

Abstract: A rugged pan for supporting a fluid-producing unit in fluid collection and overflow applications. The pan has an integrated support system for enhanced material strength, which reduces cracking and premature failure during installation and extended periods of use. Strengthening features include perimeter grommets, angled corners, at least three elongated and longitudinally-extending center supports each having a non-linear perimeter configuration, a corrugated array of laterally-extending uppercuts and undercuts substantially across the pan, and a stress-transferring member connected between adjacent non-linear supports.

Abstract: A clamping device of unitary construction comprising a tubular bridge secured between an inverted U-shaped clamping member with a vertically-extending slot and two rail plates placed in a back-to-back configuration. The dual rail plate structure permits the mounting of a pivotally-deployable float switch within the lowermost corner of a tilted fluid collection pan, when expedited response time is needed for stopping fluid flow into a collection container after only a minimal amount of fluid has accumulated in the lowered corner. The unitary construction of the clamping device, use of thumbscrews to secure its clamping member over the top edge of a fluid collection container wall, and its simple rail plate construction allow for rapid installation of a float switch within a fluid collection pan or other fluid collecting container. Vertically-extending internal ribs strengthen the clamping member. Preferred plastic materials also make the clamping device impervious to corrosion.

Abstract: A one-piece liquid-level float switch housing and drain line assembly for use with a collection tray or pan to collect condensate and shut off the source of condensate production when it exceeds a pre-established threshold level. The assembly is configured for rapid connection through a pre-formed drain line opening in the perimeter wall of a condensate collection tray/pan to place the deployable float body within its housing in a level orientation relative to the tray/pan without additional leveling adjustment. The housing has an open bottom and vertically-extending slots providing fluid inlet, debris blocking, and air venting functions for enhanced float body operation. The condensate pan/tray used with the assembly has a nesting configuration that includes a perimeter wall with varying combinations of gussets, curved ribs, angled corner configurations, and support shelves, and a central bottom surface with raised patterns, all of which strengthen the tray/pad during installation and use.

Abstract: A quick-disconnect waterproof connector for secure connection of electrical wires to one another in series, in applications where water or other fluids may be present. The most preferred connector has two connecting members each with opposing ends, a pin adjacent to a socket in side-to-side array at a first of said opposing ends, over-molding around the pin and socket, a plurality of external ribs laterally extending across the over-molding on opposing sides thereof, the over-molding around the base of the pin having a tapered boss, the over-molding extension around the distal end of the socket configured for snugly receiving the tapered boss of its paired member to create a waterproof connection, two sheathed insulated wires each connected to one of the contacts, and the over-molding also having on its second end a strain-relief extension positioned around the sheathed insulated wires as they enter the over-molding.

Abstract: A fluid-level sensing device that uses the interaction of a first magnet attached to the distal end of an external micro switch arm and a second magnet positioned within the distal end of a pivoting float body to close a circuit within the micro switch and create a shut-off signal to stop fluid production. A single housing holds the micro switch and float body, wherein magnetic forces acting through the housing wall between them and other magnet-positioning materials that separate the two magnets cause signal production. After float body deployment, manual reset of the float body is accomplished via its lever-like distal end. The main body of the micro switch, which it is snap-fit into a fixed position within the upper housing chamber for use, is entirely encapsulated in waterproof material to protect it from corrosion. Alternative ways for quick mounting of the housing to a fluid-collecting pan are contemplated.

Abstract: A fluid-collection pan configured for supporting a unit or system responsible for fluid damage risk to its surroundings. Multiple large egg-shaped supports upwardly extend from the pan's bottom surface and are integrated with it. They also each have an arcuate top surface that is transformed into an elliptical base as it meets the pan's bottom surface. Each support also has an upwardly-tapering protrusion with a convexly-shaped top edge that extends centrally from one of the longer sides of the elliptical base toward the support's top surface. The protrusion and the narrow sides of the elliptical base form a substantially triangular shape, which broadens the weight distribution of the supported fluid-causing unit across the pan's bottom surface. The top surface of each support also has a central indentation configured for receipt of a vibration isolator that provides contact with the supported unit. Optional stress-transmitting ribs may extend between adjacent egg-shaped supports.

Abstract: A one-size-fits-all pan configured for supporting a fluid-producing unit. It has a perimeter wall spaced apart from a raised central structure to provide a moat-like area for flow of collected fluid toward a wall-mounted shut-off switch. When a desired maximum amount of fluid collection is exceeded, an electrical signal is sent to stop fluid production. The raised central structure comprises a hub with radially-extending ribs that each widens into a bent distal end having non-uniform height and width dimensions, and top indentations for receipt of vibration isolators that support the fluid-producing unit at a height above that of the perimeter wall. The non-raised areas around the ribs are all connected to the moat-like area to facilitate even fluid distribution within the pan. The pan further has an up-turned perimeter lip, staggered gussets, and angled corners for added strength, and may optionally have a nesting configuration for compact storage and transport.
