Appendix A – Vent Valve Cleaning
Your ANKOM RF Gas Production System comes with a Vent Valve Cleaning Kit (part #RF22) that includes a
syringe and Vent Valve Adapter. To clean the vent valve you will need the Vent Valve Cleaning Kit, the Module
Assembly, and some warm soapy water (see pictures below).

If the vent valve fails to operate properly, it can be cleaned by following the procedure below.
(1)
(2)
Gently push the barbed end of the Vent Valve Adapter into the vent valve tube
on the side of the housing.
Remove the Glass Bottle from the Module.
(3) Fill the syringe with warm soapy water.
(4)
(5)
Attach the syringe to the end of the Vent Valve Adapter by pushing it into the
Luer fitting and rotating it clockwise.
On your GPM screen, set the Live Interval to 1 sec to speed up the valve open
and close operation.
(6) On your GPM screen, click the Valve Open box for the Module that requires
cleaning. This places a check mark in the box () and opens the valve.
Holding the vent valve open may reduce battery voltage. Before clicking the
Record button on your GPM screen to start a study, replace batteries that
show 6.6 volts or lower.
(7)
(8)
Flush the liquid through the vent valve tube and repeat. If the water does not
flow out of the bottom vent port, the software may not have opened the valve.
If this is the case, on your GPM screen, click the
Valve Open box again to
ensure that the proper Module is selected.
Flush a full syringe of warm to hot water through the vent valve tube and
repeat.
(9) Follow the rinse with an air flush to clear out the water.
(10) On your GPM screen, click the Valve Open box to close the vent valve. This
removes the check mark from the box ().
(11) Remove the Vent Valve Adapter by holding the vent valve tube against the
housing with your finger (to avoid stretching it), and pulling the adapter out.
