RESETTING DELIVERY REGULATOR PRESSURE (IN-SERVICE)
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:
CAUTION: Adjustment of the delivery regulators should be performed while the Medical IntelliSwitch is flowing gas. Adjustment in
a static condition (not flowing) will effect the available pressure during max flow conditions.
1.
Open door by loosening the four screws holding it to the cabinet.
2.
Using Figure 3, 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 4 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 3
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 5 for the location of the regulators.

After the pressure is set to the desired value, press the Output Source Pushbutton on the front panel to switch to the other
delivery regulator.
7.
Place the Allen wrench into the set screw of the second regulator and adjust the pressure to the desired value.
