Bard part number 8620-219 is a QW*S series evaporator drain pan overflow kit used on Bard Q-TEC wall mounted geothermal and water source heat pump units. This OEM safety accessory adds an overflow float switch that monitors the evaporator drain pan and shuts down the compressor if water rises to an unsafe level, helping prevent condensate spills inside the building while allowing the switch to be configured for a normally open alarm circuit when needed. Use this kit when replacing a failed overflow switch or when adding overflow protection during service, and always confirm compatibility by matching the unit series and the accessory callout in the QW*S literature before ordering.
