Grounding , page 7. Do not use PTFE tape on the
pipe joints, it may cause loss of ground across the

Flush the Equipment
For a new installation, or if the fluid in the lines is
contaminated, flush the lines before installing the
dispense valve. To avoid contaminating the fluid with

Secure the hose in the container so that it will not
come out during flushing.
NOTE: For multiple dispense positions, first flush
the dispense position farthest from the pump, then
work inward toward the pump.

the dispense position. Flush out a sufficient amount
of fluid to ensure that the entire system is clean,
then close the valve.
