FAQ - Industrial - Service/Maintenance

Q: How should I set the voltage-select jumpers (or slide switch) when changing, or installing, a circuit board?

A: The voltage selected is determined by the voltage of the pump motors being used. Input voltage (main power) should match this as well.

Q: How often should I clear report memory?

A: Frequent clearing of the report memory (also called sum/cycle memory) will reduce the likelihood of new data over-writing older data. Clear the report memory after printing the desired reports and/or when old data is no longer needed.

Q: How often should flush manifold checkvalves be serviced?

A: At least 4 times per year.

Q: How long does a squeeze tube typically last?

A: Usually 6 months under normal operation. Rough operating conditions and/or chemical incompatibility will decrease the tube life.

Q: How often should squeeze tubes be lubed? How much lube do I use?

A: Apply a light coat of lube to the tube and rollers once a month.

Q: What type of lube should be used on squeeze tubes? Is a petroleum based lube okay?

A: Use Knight KTL-20 tube lube or an equivalent silicone based lubricant. Do not use a petroleum based lubricant!

Q: Does the flow rate of the pump change when the squeeze tube is changed? Will this affect my dosage amounts?

A: The flow rate will change when a new squeeze tube is installed, however the variation may not be significant enough to cause dosage problems. Its always a good idea to check the flow rate after the tube has been changed. For systems that have an auto-calibrate function, the pump should be re-calibrated to ensure accurate product delivery.
