5. Activation valve is clogged by mineral

| 1.  Clean it or replace if necessary

2.  Use a water pressure regulator in case of more than 100PSI

3.  20PSI is the minimum required pressure.

4.  Soak venturi in hot water and inspect visually, gently removing debris. Replace the assembly if needed.

5.  Soak the valve assembly in a solution of hot water and limescale remover. Replace the assembly if needed.

2.  Soak in hot water and limescale remover to clean. Replace it if necessary

3.  Clean the hose to eliminate restriction

4.  Make sure the discharge hose dispenses be- low the dispenser insuring no back pressure

 | 1. Insufficient water pressure| 1. 14PSI is the minimum working pressure.
 | 2. Metering tip clogged| 2. Replace tip
 | 3. Foot valve clogged| 3. Soak in hot water, hand clean or change it
 |

4. Venturi clogged

| 4. Soak in hot water or limescale remover to clean. Replace it if necessary

5. Air leak in chemical pick up tubing line

| 5. Check the entire line. Replace the tubing check the connections and cable tie
 |

6. Product is too thick

| 6. Change the pick up hose. Switch to a bigger diameter. (need ¼ x 5/16 coupler)
 | 7. Product container is too far from the sys- tem| 7. The standard installation is positioning the tank under the system, 5ft max
 | 8. Excess concentration| 8. Tip is not the correct one or not inserted fully.
System continues to draw chemical after the valve is closed| 1. Chemical tank is positioned higher than the dispenser causing siphoning| 1. Move chemical container below the dispenser discharge point
