IFS Single Phase Duplex

Single Phase Duplex Demand / Timed Dose

Installer Friendly Series® control panels utilize circuit board technology for advanced pump control and system monitoring.

The Installer Friendly Series® Single Phase Duplex Demand/TD control panel is designed to control two alternating 120/208/240V pumps in water and sewage installations.  

The IFS panel features a simple, easy-to-use touch pad on the inner door for programming and system monitoring.  The panel configuration can be easily converted to demand dose or timed dose in the field.

The optional C-Level™ sensor is a pressure transducer that senses the liquid level in the tank and sends a signal to the IFS panel. Pump activation levels can be adjusted by using the panel touch pad. C-Level™ CL40 sensor operating range is 3-39.9 inches (7.6-101.3 cm). C-Level™ CL100 sensor operating range is 3-99.5 inches (7.6-252.7 cm).
