Use the two 23/64 thru holes in the Body to mount
the Model 64. The Model 64 may be mounted in
any orientation.
Clean all pipelines to remove dirt and scale before
installation.
Apply a minimum amount of pipe compound to the
male threads of the tting only. Do Not use teon
tape as a sealant. Start with the third thread back and
work away from the end of the tting to avoid contami-
nating the regulator. Install the regulator in the air line.
The Inlet and Outlet ports are labeled “In” and “Out”.
Tighten all connections securely. Avoid undersized
ttings that limit the ow through the regulator. For
more information, see Figure 1.
NOTE:
The Model 64 has an Adjustment Screw that con-
trols output pressure. To increase pressure, turn
the Adjustment Screw clockwise. To decrease
pressure, turn the Adjustment Screw counterclock-
wise. For more information, see Figure 1.
Oil free air must be applied to the regu-
lator. If an air line lubricator is used, it
MUST be located downstream of the
regulator to avoid interference with per-
formance.
