MODELS “SCH & SCHMS” - EMITTER NOZZLE CLEANING INSTRUCTIONS
If the nozzle appears plugged or seems to sputter, it may be that some particles or mineral buildup has occurred in the
fluid body of orifice. Follow these simple instructions to solve the problem. Also, depending on the quality of the local
water supply, regular cleaning should be carried out as a matter of course.
Step 1: Unplug the controller
Step 2: Bracing the nozzle body with one hand, carefully loosen the hex nut Cap on the front of the emitter nozzle,
and remove (be careful not to lose the Air Cap when you remove the Hex Nut).
Step 3. Remove the fluid Body from the nozzle body and look through it towards a light. If you cannot see daylight,
simply rinse under a hot water and blow through the orifice until the blockage is cleared. For more severe mineral
deposits, soak the Fluid Body in an Efferdent solution for approximately 15 minutes, rinsing afterwards. Do Not
insert needles or similar sharp points into the orifice as this will enlarge the size and affect spray performance.
Step 4: Replace the Fluid Body back into the main body (black “O” ring end in first).
Step 5 Making sure the Air Cap is sitting flush inside, screw on the Hex Nut and tighten
Step 6: Plug in controller
