and protect expensive mechanical components from overheating

Measuring 4-3/4 inches in diameter with a 2-1/16 inch height

The MTZ series specifically requires 175PZ polyester oil (POE)

Calibration is performed via the zero adjustment screw located at the bottom of the faceplate

Integrating this condensate safety switch during routine maintenance or after a hard lockout ensures the system maintains its AHRI-rated efficiency while protecting the building from potential water damage

Crown Engineering H24-30 Spiralink Coupler 322838-752 and protect expensive mechanical componentsThe Crown Engineering H24 30 Spiralink Coupler is a heavy duty, one piece alternative to traditional 4 spring "fly away" couplings found in hydronic circulator pumps. Engineered for 1 2" x 1 2" shaft sizes, this CCW (Counter Clockwise) coupler features a unique single spring design that provides 3 dimensional flexibility. This allows the assembly to act as a universal joint, compensating for shaft misalignment that typically destroys standard
