WARNING PRESSURIZED EQUIPMENT HAZARD Spray from the gun, hose leaks, or ruptured components can splash fluid in the eyes or on the skin and cause serious injury. Do not stop or deflect fluid leaks with your hand, body, glove, or rag. Follow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve the pressure; stop spraying; clean, check, or service the equipment; and install or clean the fluid nozzle. Tighten all the fluid connections before operating the equipment.

Installation Fluid pressure regulators are used for accurate, positive control of the fluid pressure to spray guns, dispensing valves or atomizing heads. Regulators installed at circulating line take-offs or pumps are used to reduce main line pressure and maintain the desired fluid pressure to the spray gun or atomizing head. Before Installing the Fluid Regulator 1. Determine where to locate the regulator. Installing the Fluid Regulator 1.
Operation CAUTION The new system must be cleaned and tested thoroughly before admitting fluid to the regulator to avoid contaminants clogging or damaging the regulator. Always use the lowest possible air and fluid pressures for your application. High pressures cause premature spray nozzle and pump wear. NOTE: Reference numbers and letters in parentheses in the text refer to the Figs. and Parts Drawing. Pressure Relief Procedure 2.
Operation 7. Adjust the fluid regulator to the desired setting. a. Spring Operated Regulators Only (see Fig. 3). The regulator can be adjusted in two ways: Using the male end (B) of the regulator key (24), turn the socket–head adjustment screw (19) fully clockwise. Verify that the pressure setting has not changed. Using the female end (A) of the regulator key (24), turn the adjustment screw (12) counterclockwise to return to the desired pressure setting. b. Air Operated Regulator Only.

Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Before servicing this equipment always make sure to Relieve the Pressure. Check all possible remedies in the Troubleshooting Chart before disassembling the fluid regulator. Problem Cause Solution No pressure regulation Damaged or clogged air regulator or line (214980 only) Clear obstruction in line, service regulator if necessary.
Service Service of the Air Operated Regulators WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. 1. Shut off the pump. 2. Close the ball valve at the regulator’s air inlet. Refer to Fig. 2. 3. Release all the air and fluid pressure in the regulator and disconnect the air and fluid lines. 4. Remove the regulator from the system. 5. Remove the swivel union (23) and spring (40) from the regulator body. 6.
