M Series HVAC Series Condensate Level Switches M8000 Madison Company offers a standard family of water-activated level switches designed for condensate return systems in HVAC and HVACR systems. These condensate level float switches can be used for the return of hot condensate in a boiler system, in an air conditioning condensate line, or to give a signal to a pump or compressor control when water is detected in the drain pan. The M8000-C float switch is designed for either a press fit into a standard 3/4” schedule 40 PVC pipe tee allowing for future clean out, or glued in place using standard PVC pipe cement. This vertically mounted switch will provide an excellent level signal at up to a 30° angle and incorporates a vent hole for line air to escape. M8000-C The M8000, also a vertically mounted switch, requires a mounting hole to accommodate a 1/8” NPT fitting. The M8700-C is a horizontally mounted float switch for use where side mounting is preferred, such as in the side of a pan or reservoir. M8700-C These switches can also be used in compressed air condensate drain lines that are normally found on intercoolers, after coolers, dryers, drip legs and receiver tanks. They are cost-effective solutions when compared to electric solenoid valve methods.
