Floor Boxes and Power Supplies Adjustments

The air and water pre-regulators are located in the floor box. Before making adjustments, verify that the
air compressor is ON, and that it maintains 125 psi.

If the air pressure is lower than 80 psi, refer to the compressor instructions. Some compressors, especially
older ones, produce a maximum of 60-80 psi. Adjustments on this type of compressor should be done
when air pressure is near or reaches maximum psi. A-dec systems will usually function in this pressure
range, although at a reduced performance.

Adjusting
Regulators

Task Description

1Be sure manual shutoff valves are fully open (turned counterclockwise).

2Turn the system ON and check pressures.

• Air pressure should be 70 - 80 psi.

•Water pressure should be 35 - 40 psi.

3 Operate the syringe.

4Watch the gauges for a drop in pressure. In units manufactured before December 1999, replace the

filters if:

• Air pressure drops by more than 15 psi.

•Water pressure drops by more than 10 psi.

5Adjust the air or water pressure as required by turning the pre-regulator knob:

• Clockwise to increase pressure.

• Counterclockwise to decrease pressure.

NOTE: The gauge will not indicate a change in pressure when decreasing system air or water pressure,

until pressure from the system is relieved. Activate the syringe for a few seconds and check the
gauge. Repeat this process each time a decrease adjustment is made.
