SETTING DELIVERY REGULATOR PRESSURE
The Delivery Regulator Pressure is factory set based on the model purchased. If it is necessary to
change the pressure of the regulators after installation perform the following steps:
1. Open door by loosening the four screws holding it to the cabinet.
2. Using Figure 4, locate DIP switch SW4 at the bottom of the electronic circuit board on the
door. Move SW4-4 to the ON position. The front panel display will show a screen similar
to Figure 5 indicating the system is in CALIBRATE mode. The front panel display will
show the inlet pressure from the side that it is currently drawing from.
Figure 4
3. Locate the Allen wrench attached to the inside panel.
4. There is a green light to the left or right of the delivery display that indicates which delivery
regulator is in use. If the left light is ON, the pressure being displayed in the delivery
display is the output pressure of the left regulator. Similarly, if the right green light is ON
the pressure being displayed is from the right regulator.
5. Locate the Allen wrench attached to the inside panel. Starting with the delivery regulator
that is currently in use, place the Allen wrench into the set screw and adjust the pressure to
the desired value. Turning the set screw clockwise increases pressure. Counterclockwise
decreases pressure. The system will not decrease in pressure if there is no flow. See Figure
6 for the location of the regulators.
