APPLICATION
PRECAUTIONS
The installer should be an experienced service technician. When drilling the holes for the installation extreme care
should be taken not to damage interior components of the heating or cooling system or wiring and plumbing behind
wall panels.
INSTALLATION
1. Select a location on the blower compartment between
the air filter and the blower and drill a 7/16" diameter hole.
Insert one end of the vinyl tubing about 2" into the hole.
2. On a wall, enclosing the furnace room for example,
mark a position where the filter gage can be easily seen
and is within reach of the vinyl tube.
3. Drill a 1/2" diameter hole through the wall and feed the
vinyl tube through the hole. Keep overall length of tubing
used as short as possible.
4. Push the three plastic retainer clips out from the back
of the gage with a blunt tool. They will be replaced with
the three #4-24 x 1" screws included.
5. Push the vinyl tubing over the pressure sensing tube
of the gage and move the gage back against the wall in a
level position. Drill three 3/32" diameter holes through
the gage holes. Drive the three screws to hold the gage
in place. Do not overtighten.
6. Install a clean filter and run blower on highest speed.
With a small screwdriver adjust the calibration screw, on
the face of the gage, to put the pointer in the clear area in
the center of the blue (FILTER IS CLEAN range).
