Installation Fluid pressure regulators are used for accurate, posi- Installing the Fluid Regulator tive control of the fluid pressure to spray guns, dis- pensing valves or atomizing heads. 1. Remove the temporary plumbing and install one regulator for each spray gun. See the Dimension- Regulators installed at circulating line take-offs or al Drawing on page 21 for regulator dimensions.
Operation 2. Shut off the pump and relieve fluid pressure in the CAUTION system by triggering the gun and opening the back pressure regulator or other bypass valve. D The new system must be cleaned and tested thoroughly before admitting fluid to the regulator 3.
