RESETTING INLET REGULATOR PRESSURE (IN-SERVICE)
The Inlet 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 inlet regulators could result in reduced flow performance and malfunction of the reserve inlet
(optional) for the Medical IntelliSwitch.
1.
Open door by loosening the four screws holding it to the cabinet.
2.
Locate the Allen wrench attached to the inside panel.
Figure 2
3.
Starting with the inlet regulator that is currently in use, place the Allen wrench into the set screw and adjust the pressure to
the desired value. The delivery pressure of the inlet regulator can be seen on the internal pressure gauges. Turning the set
screw clockwise increases pressure. Counterclockwise decreases pressure. The system will not decrease in pressure if there
is no flow. See Figure 2 for the location of the regulators.

After setting the first inlet regulator, press the bank select button on the front panel to switch to the other bank. Repeat step 3
to set the second inlet regulator. For best performance, both inlet regulators should be set to the same pressure.
