The spring determines the mechanical tension on the diaphragm to set the outlet pressure regardless of gas density
Using a rating lower than 189-227 MFD may result in insufficient torque
Replacing the clamp during a diaphragm change ensures the regulator maintains its set point stability under high flow conditions
non-slip mechanical connection necessary for precise airflow modulation
the bimetal disc triggers a circuit break to prevent heat exchanger fracturing or component damage
Carrier HH18HZ195 Rollout Switch The spring determines the mechanicalThe Carrier HH18HZ195 Rollout Switch is a critical safety component designed for Carrier furnace flame rollout protection. This OEM furnace safety switch features a Single Pole Single Throw (SPST) configuration with an automatic reset function, ensuring the system remains operational once safe temperatures are restored. Engineering specifications dictate a precise 195F open point to interrupt the heating cycle during abnormal combustion conditions,
