The Photohelic combines the functions of a differential pressure gauge and a pressure-based switch. The gauge function measures the pressure difference between the clean and ambient air and provides a visual display of filter condition. The low-pressure tap is located in the clean-air plenum on the back of the cabinet. The pressure-based switch function provides high-pressure ON and low-pressure OFF control of the filter cleaning system.

Choose a convenient, accessible location on or near the unit for mounting that provides the best visual advantage.

Mount the gauge to the remote panel or door using the mounting ring, retaining ring, and four #6-32 x 1 1/4-inch screws. Do not tighten screws. Connect one 1/8-inch NPT x 1/4-inch OD male adapter to the low-pressure port of the gauge. Align the adapter to the 2.375-inch hole in the right-hand side of the mounting bracket. Tighten screws.

Zero and maintain the gauge as directed in the manufacturer’s operating and maintenance instructions provided.
