Heil Quaker ICP 1174684 Pressure Switch 321894-708 as the orifice limits gas

as the orifice limits gas escapement to within ANSI standards in the event of a diaphragm rupture

Using the S1-373-39504-007 conversion ensures that vibration isolation and internal stresses are managed according to the original manufacturer's design

This dual pressure control features a low-pressure range of 10" WC to 100 PSI and a fixed high-pressure cutout to ensure compressor protection against system abnormalities

Advanced Logic Control: Onboard microprocessor control adjusts fan RPM to maintain optimal head pressure and prevent equipment cycling issues

Heil Quaker ICP 1174684 Pressure Switch 321894-708 as the orifice limits gasThe Heil Quaker ICP 1174684 Pressure Switch is an essential safety component designed for high pressure monitoring in ICP HVAC systems. Engineered as a 610 420# High Pressure Switch, this control opens the electrical circuit when internal system pressures reach 610 PSI and resets automatically when pressure drops to 420 PSI. This precise refrigerant pressure cutout prevents compressor damage due to restricted airflow, overcharging, or condenser fan
