FIG. 90
CLEANING THE NOZZLE & VENTURI
A
clean nozzle & venturi (See Figure 90) is a necessi-
ty for the water filter to work properly. This small
component creates the suction to aspirate (bring air
into) the mineral tank during recharges. If it should
become plugged with sand, silt, dirt, etc., the water fil-
ter will not work to remove iron from the water.
To get access to the nozzle & venturi, remove the
water filter’s top cover. Put the bypass valve(s) into
the bypass position. Be sure the water filter’s main
valve is in “service” position (no water pressure at
nozzle & venturi). Then, holding the nozzle & venturi
housing with one hand, unscrew the cap. Do not lose
the o-ring seal. Lift out the screen support and
screen. Then, remove the nozzle & venturi disc, gas-
ket and flow plug. Wash the parts in warm, soapy
water and rinse in fresh water. Be sure to clean both
the top and bottom of the nozzle & venturi disc. If
needed, use a small brush to remove iron or dirt. Do
not scratch, misshape, etc., surfaces of the nozzle &
venturi.
Gently replace all parts in the correct order. Lubricate
the o-ring seal with silicone grease and locate in
place. Install and tighten the cap by hand, while sup-
porting the housing. Overtightening may break the
cap or housing. Put the bypass valve(s) into “service”
position.
Recharge the filter and advance the valve to the
“aspirate” (A) position. Remove the screen from the
barbed fitting on the inlet of the check valve and
determine whether there is suction. Put the screen
back in place when finished checking.
