CLEANING THE NOZZLE & VENTURI
A clean nozzle & venturi (See Figure 154) is necessary
for the EcoWater Systems conditioner/refiner to work
properly. This small unit creates the suction to move
brine from the brine tank into the resin tank. If it should
become plugged with dirt, silt, sand, etc., the EcoWater
Systems conditioner/refiner will not work and hard water
will result.
To get access to the nozzle & venturi, remove the con-
ditioner/refiner’s top cover. Put the bypass valve(s) into
the bypass position. Be sure the conditioner/refiner is
in the service cycle (no water pressure at the nozzle &
venturi). Then, holding the nozzle & venturi housing
with one hand, turn the cap to remove it. Do not lose
the o-ring seal. Lift out the screen support and screen.
Then, remove the nozzle & venturi. Wash the parts in
warm, soapy water and rinse in fresh water. If needed,
use a small brush to remove iron or dirt. Be careful not
to scratch, misshape, etc., surfaces of the nozzle &
venturi. Also, check and clean the gasket and flow
plug(s) if dirty.
Carefully replace all parts in the correct order.
Lubricate the o-ring seal with silicone grease and put in
place. Install and tighten the cap, by hand only. Do not
overtighten, which could break the cap or housing. Put
the bypass valve(s) into service (conditioned water)
position.

RESIN BED CLEANING
If the water supply contains clear water iron, regular
resin bed cleaning is needed to keep the bed from coat-
ing with iron. Use resin bed cleaner, available from
EcoWater Systems, following directions on the contain-
er. Clean the resin every six months, or more often if
iron appears in the conditioned water supply.
