 Gauge 

Electrical service or maintenance 

work must be performed by 

a qualified electrician and comply with all 

applicable national and local codes.
Turn power off and lock out electrical 

power sources before performing service or 

maintenance work.
Do not install in classified hazardous 

atmospheres without an enclosure rated for 

the application.

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-air and dirty-air plenums and provides a visual 
display of filter condition. The high-pressure tap is 
located in the dirty-air plenum and a low-pressure tap 
is located in the clean-air plenum. The pressure-based 
switch function provides high-pressure ON and low-
pressure OFF control of the filter cleaning system.
1.  Choose a convenient, accessible location on or near 

the unit for mounting that provides the best visual 
advantage.

2.  Mount the gauge to the remote panel or door using 

the mounting ring, retaining ring, and four #6-32 x 1 
1/4-in screws. Do not tighten screws. Connect two, 
1/8-in NPT x 1/4-in OD male adapters to the gauge’s 
high- and low-pressure ports. Tighten screws.

3.  On the back of the gauge, remove four #6-32 x 5/16-in 

screws and plastic enclosure. Set aside. Add two 
jumper wires supplied by customer. Remove the 
jumper from the pressure switch located on the timer 
board, if equipped. Using the 3/4-in conduit opening, 
wire the gauge as shown. Reassemble and fasten 
enclosure securely.

4.  Thirty-five feet of plastic tubing is supplied and must 

be cut in two sections. Connect one section of tubing 
from the gauge’s high-pressure port to the pressure 
fitting located in the dirty-air plenum. Connect 
remaining tubing from the gauge’s low-pressure 
port to the fitting in the clean-air plenum. Additional 
tubing can be ordered from your representative.
