INSTALLATION
1. Install as close as possible to where regulated air is needed.
2. Install the unit with the air flowing through the body in the direction indicated by the arrow.
3. Install the same pipe size unit as the pipe line in use. Avoid using fittings, couplings etc. that restrict the airflow, unless maximum flow is not needed.
4. Regulator may be installed with the adjusting knob in any position. Attach gauge to one 1/4" female gauge port and plug the other 1/4" female port, or use it as a regulated outlet port.
5. Turning the adjusting screw clockwise increases the regulated pressure and turning it counterclockwise decreases the regulated pressure.
6. Panel mount regulators require a 17/8" diameter hole and are mountable on panels from 1/8" to 1/2" thick.
MAINTENANCE
1. The regulator can be disassembled for servicing without removal from line.
2. Occasionally remove bottom plug and clean plug, body and valve seat (vent air line on both sides of regulator).
3. TO DISASSEMBLE-shut off air to regulator and vent air line on both sides of regulator. Turn adjusting screw counterclockwise to relieve adjusting knob (panel mount nut, if used), tamper-resistant kit (on tamper-resistant models) and cover cap. Remove the six screws, cover and regulating spring. Diaphragm assembly can now be removed. By removing bottom plug and spring the valve stem can be removed from the bottom of the regulator
4. IF UNIT WILL NOT REGULATE TO DESIRED PRESSURE OR IF PRESSURE BECOMES EXCESSIVE remove bottom plug, spring, and valve assembly. Clean and check o-ring, valve stem and valve seat for water damage. Replace worn or damaged parts. Install Repair Kit No. RRP-95-951 for self-relieving models and Repair Kit No. RRP-95-950 for nonrelieving models for complete overhaul.
