Regulator Setting
• It’s recommended that you check the regulator pressure 4 times a year to verify the
regulator is still set at the desired pressure setting.
• Open the cover to the control box.
• Remove the metal cap on the check port fitting on the regulator.
• Check the pressure with an accurate gauge, such as a master gauge.
• 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.
