Always use a multimeter to verify input voltage between the R and C terminals and ensure proper chassis grounding to prevent false flame-out conditions

Why choose the QPA2000 over a model with a display

it supports CCW rotation (lead end) and utilizes shell-screw mounting for secure integration

this SPST pressure switch ensures that the induced draft motor is generating sufficient vacuum to safely vent combustion gases in environments where air density is lower

the Copeland 998-E022-01 maintains the chemical stability necessary to prevent acid formation and copper plating within the cooling circuit

Cleveland Controls NS2-1068-01 Pressure Switch 318518-761 Always use a multimeter toThe Cleveland Controls NS2 1068 01 Pressure Switch is a critical OEM replacement engineered for precise atmospheric monitoring in high demand HVAC systems, industrial air handlers, and furnace draft inducer circuits. Factory calibrated to a fixed set point of 0. 20" w. c. (Water Column), this differential air pressure switch ensures the blower motor is moving sufficient air to safely vent combustion gases or maintain required static pressures.
