WARNING

Do not use PTFE tape on pipe threads. Such use could cause a hazardous condition due to loss of grounding continuity. Also, if pieces of the tape break off, the function of the regulator could be affected.

The installations shown in Fig. 1 are only a guide for selecting and installing a circulating or direct system; they are not actual system designs. Contact your Graco distributor for assistance in designing a system to suit your needs.

NOTE: Before you install the regulator, thoroughly flush the system to remove metal chips and other contaminants. A fluid filter (D) of 60-mesh or finer should always be installed upstream of the regulator.

Connections

Install the fluid regulator (G) in the spray gun fluid supply line (F), as shown in the typical installation drawings on this page. Connect only one spray gun or dispensing valve to each fluid regulator.

Apply pipe sealant to the male pipe threads, and connect the fluid supply line (F) to the fluid regulator’s 3/8 npt(f) inlet. Connect the line from the gun (J) to the fluid regulator’s 3/8 npt(f) outlet. Install the gauge or plug into the 1/4 npt(f) gauge port.

Make sure the direction of fluid flow agrees with the IN and OUT markings on the regulator body.

Flush the System

The regulator was tested in lightweight oil. Flush the entire system with a solvent compatible with the fluid being dispensed. Then test the system.

Mounting Bracket

A Mounting Bracket is available for mounting the regulator. Order Part 222515 for the bracket and mounting hardware.
