The unit integrates a threaded cleanout port with a mechanical float switch in a single assembly, allowing drain line access and high-water-level detection without separate components. The float switch interfaces with 24 VAC low-voltage control circuits to trigger equipment shutdown or alarm signaling when condensate reaches an unsafe level in the secondary drain pan. Licensed HVAC technicians install this fitting as part of a compliant condensate overflow protection setup in residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThis assembly is suited for residential and light commercial HVAC installations where secondary drain pan monitoring is required by code or manufacturer specification. The cleanout port accepts standard mechanical snake tools and chemical drain treatments, making routine condensate line maintenance straightforward without disconnecting drain plumbing. The integrated float switch eliminates the need for a separate overflow sensor, simplifying installation in tight mechanical spaces around air handlers and fan coil units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombined cleanout fitting and float switch in a single assembly reduces component count\u003c\/li\u003e\n\u003cli\u003eThreaded cleanout port provides access for mechanical and chemical drain line cleaning\u003c\/li\u003e\n\u003cli\u003eMechanical float switch detects high condensate water levels in secondary drain pans\u003c\/li\u003e\n\u003cli\u003eRated for 24 VAC low-voltage control circuits standard in residential and light commercial HVAC systems\u003c\/li\u003e\n\u003cli\u003eDesigned for equipment shutdown or alarm circuit integration on high-water detection\u003c\/li\u003e\n\u003cli\u003eSupports secondary pan safety protection practices per local mechanical codes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for residential and light commercial HVAC condensate drain pan safety applications requiring an integrated cleanout and float switch assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with condensate drain systems and low-voltage control wiring. Shut down and lock out the HVAC unit before installing or servicing this assembly. Verify that the float switch wiring connections comply with the equipment manufacturer wiring diagram and applicable local mechanical and electrical codes. Do not energize the control circuit until all fittings are secure and the drain pan is confirmed dry and free of debris.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential and light commercial HVAC condensate drain secondary pan safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Mechanical float switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: High condensate level detection with equipment shutdown or alarm output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RECTORSEAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSD-AA1-FS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51342872379698,"sku":"MSD-AA1-FS","price":40.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555126.png?v=1782009146","url":"https:\/\/voomisupply.com\/products\/rectorseal-msd-aa1-fs-condensate-drain-float-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
