Installation
User must verify that the regulator is rated for the system operating pressure and has
the proper connections and accessories for the type of gas and pressures required for
their application.
Inspect the regulator for evidence of contamination or damage. Regulators with any
signs of contamination or damage should not be used.
When installing the regulator to the airline, reference the arrow on the front and back
of the regulator for air flow direction.
Use a filter to remove dirt and supply clean air to your application.
Filter must be
installed ahead of the regulator
.
If an airline lubricator is used, it MUST be located
downstream of the regulator to avoid any interference with regulator.
Note: Do not apply excess torque when installing the regulator and/or gauge. We recommend
use of liquid Teflon over Teflon tape.
Operation & Adjustments
Before supplying the air, turn the adjusting knob counter-clockwise until
compression is released from the control spring. Turn on the air supply and adjust
the knob to set the desired secondary pressure by turning the knob clockwise.
Note: Adjustment knob must be pulled away from the body of the regulator to operate. After
desired secondary pressure is set, pushing the knob back towards the body will lock the
control knob.
