10. WATER
10.1 PRIMNG THE SYSTEM
IMPORTANT!
The water line must be primed before mixing. Air in the lines will cause false readings from the water flow
meter and delay the water flow into the mix bowl on start-up.

To prime the pump, ensure the suction ball valve is open at
the water tank and open bleed valve .

Turn water pump on at the control panel (button #17) and
allow initial air out of the system through bleed port.

Close bleed port when air slows or stops sputtering out of
the valve.

Turn on the water outlet into the mix bowl (button #13) to
allow the water to flow through to the outlet. Turn off the
water outlet when air in the line is gone and flow reading
are stable.
10.2 STRAINER CLEANING AND REPLACEMENT
IMPORTANT!
A dirty water strainer will cause the Commander control system to speed up the water pump when in auto
mode, which will eventually cause it to go into a fault if it can’t meet its water flow target. Check the water
strainer regularly for buildup.

To remove and inspect the water inlet strainer unthread the
cap and pull the strainer out of the housing.

Be careful not to lose the seal .

Clean the strainer as necessary ensuring all debris is
removed and outer mesh is clean.

If the strainer is plugged beyond reasonable cleaning or it is
damaged, then replace it.
