Pressure Switch Application & Service FAQ
Is the 5H0750300003 field adjustable?
No. This switch is factory-calibrated to 0.27″ W.C. specifically for Modine heating equipment. Field adjustments are not recommended to ensure the safety integrity of the unit.
What is the recommended replacement interval?
To maintain optimal safety and prevent nuisance shutdowns, we recommend replacing the pressure switch every 5 years or approximately every 50,000 operational hours.
What is the best orientation for mounting?
While the switch can function in any position, vertical mounting is recommended for optimal performance and to prevent moisture buildup in the diaphragm housing.
Does it have an automatic reset feature?
Yes. Once the heater’s pressure conditions return to normal operating levels, the switch automatically resets, allowing the system to continue operation without manual intervention.
