2.Trigger the dispense valve into a waste container to relieve pressure.

3.Open any bleed-type master air valves and fluid drain valves in the system.

The Matrix meter must be powered, nozzle open (counter clockwise), and in dispense mode for fluid pressure to be relieved.

4.Leave the drain valve open until you are ready to pressurize the system.

Air compressor: Follow the manufacturer's recom- mendations.

Fluid supply container: Follow the local code.

To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the valve firmly to the side of a grounded metal pail, then trigger the valve.

Pre-installation Procedure

1.Relieve the pressure. Follow the Pressure Relief Procedure on page 8.

2.Close the shut-off valve (J). See FIG. 4.

3.Ground the hose and reel or console. See Ground- ing.

4.If this is a new installation or if the fluid in the lines is contaminated, flush the lines before you install the metered valve.
