OPTION

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 teon

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.
