• If the pressure is correct, replace metal cap and close the lid.
• If the pressure is above or below the desired setting, adjust the pressure using the adjustment
knob. See Figure 36.
• If the pressure is “low” pull up on the regulator’s knob to unlock. Turn the knob clockwise
to increase the pressure. Allow the pressure to stabilize then check the pressure 2-3 times
to verify correct pressure. If the pressure is correct, push the knob back down to lock in
place and replace the metal cap.
• If the pressure is “high” turn the knob counter-clockwise to decrease the pressure. Allow
the system to stabilize and check the pressure 2-3 times to verify correct pressure.
Continue to decrease or increase the regulator until the desired pressure is achieved.
