MAGNEHELIC GAUGE
1. Mount the magnehelic gauge into the magnehelic
mounting bracket following the mounting instructions
contained in the magnehelic packaging.
2. Mount the two male barb fi ttings in the pressure ports
located on the side of the magnehelic gauge.
3. Mount the two pressure port plugs in the pressure ports
located on the back of the magnehelic gauge.
4. Mount the bracket using the four (4) self-taping screws
provided.
5. Using the 1/4” diameter clear tubing connect the
“LOW” or “-” pressure port on the gauge to the clean
air plenum and the “HIGH” or “+” pressure port to the
dirty air plenum (Figure 13).
PHOTOHELIC GAUGE
1. Mount the photohelic gauge into the photohelic
mounting bracket following the mounting instructions
contained in the photohelic packaging.
2. Mount the two male barb fi ttings in the pressure ports
located on the side of the photohelic gauge.
3. Remove cover from electrical box so that wiring
diagram on back of cover can be used.
4. Remove the two red wires that are connected to the
timer board pressure switch input (HI & COM) and
relay CR1, or the two red wires that are connected to
the timer board pressure switch input (HI & COM)
and the differential pressure switch (HI & LOW). See
specifi c unit wiring schematic for further clarifi cation.
5. Wire the photohelic gauge as the electrical diagram
shows. Use the 3/4” conduit opening on the
photohelic, connecting to the pulse control electrical
box.
6. Replace the cover back onto the photohelic gauge and
mount the bracket using the four (4) self-taping screws
provided.
7. Using the 1/4” diameter clear tubing connect the
“LOW” or “-” pressure port on the gauge to the clean
air plenum and the “HIGH” or “+” pressure port to the
dirty air plenum (Figure 14).
8. The right set point dial of the gauge should be
positioned at the fi lter differential set point you want
the Roto-pulse system to be enabled. The left should
be positioned at the fi lter differential set point you wnat
the Roto-pulse sytem disabled.
