•
If air and valves are OK, check the Infrared Sensor
o
IR is Bad – replace ( Note: IR may sometimes sense water but not
detergent)
o
IR is Good:

Check the Coupler as described above
4. Purge sequence does not stop, and there is no more liquid (air or CO
2
)
•
Make sure Air and CO
2
are on at proper pressure
•
Check for a hiss of air
o
Hissing and Probe is off – the IR Probe is bad
o
No Hissing – check the air supply and pressure
5. Liquid is purging for a long time
•
Check that air pressure is set at 22-23 psi and you are using a 1” hose
Mineral deposits or
growths
Prevent this by switching between Acid and Caustic wash cycles.
•
Using just one may allow growths or accumulation of buildup deposits, while using
both maintains a balance of cleaning

Dosing Unit / Proportioner
or
Fails To Draw Chemical
Check the following:
•
The Proportioner outlet tubing is not attached
o
Connect the tubing and prime the Proportioner
•
There is insufficient water supply pressure
o
Ensure you meet the 15 gpm at 40-60 psi
•
The Proportioner outlet tubing was cut too short for priming
o
Pinch the outlet tube to create back pressure, which will cause the unit to
prime, after which, the foot valve will keep the inlet tube primed
---
Dosing Unit / Proportioner
or
Stops Drawing Chemical
Do the following:
a) Proportioner metering tip clogged with dried chemical
•
Remove proportioner tip and inject hot water
b) Inspect the foot valve for dried chemical or dirt clogs
•
Soak in hot water and clean
c) Remove the buildup of calcium carbonate (lime) inside the proportioner
•
Soak it in a delimiting solution, or vinegar, to restore it to working order
Dosing Unit / Proportioner appears clean, but
there is no suction
•
Remove proportioner and soak in hot water to
clear interior passages
Dosing Unit / Proportioner
Continues To Draw
Chemical After Water
Valve Closes
The chemical supply is resting higher than the bottom of the discharge tube, creating
a natural siphon
•
Lower the supply container or hang up the outlet tube after use
---
Air Purge Doesn’t Stop
Check the IR Probe. If it’s not sensing the difference between liquid and air and
switching off, it has become defective. Replace the Sensor. This may occur right
after a detergent rinse, and continue to blow air for a long time.
