The ACS-4, Auxiliary Condensate Overflow Safety Switch, is easily installed in the drain line to detect downstream clogs and interrupt the thermostat circuit to shut off the unit before flooding occurs. The switch can also be installed to activate audible and/or visual alarm circuitry. The ACS-4 comes complete with a 1" × 3/4" reducing bushing and a 3/4" plug for auxiliary drain pan outlets. The switch/holder assembly is easily removed to enable cleaning of any clog in the line.
