Frequently Asked Questions
Q:
How do I set my pressures?
A:
First, set the dispense pressure. A dispense valve hose and nozzle should be used, which will maintain at
least 500 psi (3.5 MPa, 34.5 bar) back pressure at the fluid control regulator outlet at your lowest flow rate
setting.
Second, set the feed pressure. Once you are running, back down the feed pressure to a point where the
regulator inlet pressure stays at least 500 psi (3.5 MPa, 34.5 bar) greater than the regulator outlet pressure,
when dispensing at your maximum flow rate. If you will have multiple valves open at the same time, being fed
by the same feed pump, do this check with all of those valves open. Excessive feed pressure will cause
excessive wear.
Q:
What is the recovery procedure if the TouchScreen or EasyKey panel lock-up?
A:
The process can continue to run. When you are not dispensing, cycle the power to reboot the display.
