To get access to the nozzle & venturi, remove the water softener's top cover. Put the bypass valve(s)
into the bypass position. Be sure the water softener is in soft water (service) cycle (no water pressure at
nozzle & venturi). Then, holding the nozzle & venturi housing with one hand, unscrew the cap. Do not
lose the 0-ring seal. Lift out the screen support and screen. Then, remove the nozzle & venturi disc,
gasket and flow plug(s). 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 0-ring seal with silicone grease and locate in
place. Install and tighten the cap by hand, while supporting the housing. Overtightening may break the
cap or housing. Put the bypass valve(s) into service (soft water) position.
Recharge the softener to reduce water level in the tank. This will also assure that the softener is
completely recharged and ready to provide softened water again. Check the water level in the tank by
looking down the brinewell. If the water level does not drop after a recharge, the problem has not been
resolved. Call 1-(480) 969-7251, Monday – Friday, 8 am to 5 PM Mountain Time.

AUTOMATIC ELECTRONIC DIAGNOSTICS

This water softener has a self-diagnostic function for the electrical system (except input power and/or
water meter). The water softener monitors electronic components and circuits for correct operation. If a
malfunction occurs, an error code appears in the display.
