10.3 FLOW METER CLEANING AND REPLACMENT
IMPORTANT!
Depending on the water source it may be required to remove the water flow meter and clean it periodically. If
the water source is not clean, then this may be required more often. Using an open water source (algae, etc.)
will require more cleaning and maintenance than city water.

To clean or replace the water flow meter uncouple the
quick connects at each end and remove the U-bolts on
either side of the flow meter.

Disconnect the air lines to the ON/OFF valve and the
electrical cable. Remove the assembly from the flow meter
cabinet. Removing the right-hand side panel will make
removing assembly easier.

Disconnect the pipes from the flow meter to replace it and
re-apply Teflon tape as required.

To clean the flow meter, use a non-metal pipe cleaning
brush or a lint-free cloth.
11. ADMIX
11.1 PRIMING THE SYSTEM
IMPORTANT!
The admix lines must be primed before mixing. Air in the lines will cause false readings from the flow meters
and delay the admix flow into the mix bowl on start-up.

To prime the admix pumps first ensure the outlet ball valves
are in the off (zero) position. This cycles the fluid
straight back to tank instead of the mix bowl outlet.

Run the pump in prime mode (amber led position). Take
the lid off the admix tank and see if fluid is coming out of re-
circulation tube in the top.

If fluid is circulating or the pump has been on for several
seconds turn the ball valve to the fully open position.
Have a pail to catch the chemical coming out of the line into
the mix bowl. Keep running the pump until a steady stream
of fluid appears and no visible air is in the line.

You should also have a steady flow reading on the screen if
all the air is out.
