MiniDos Remote Injection Demonstration

Dosmatic Remote Bypass Kit

This is the Dosmatic video of our Remote Bypass Kit, which is attached to an injector in operation. Our video will show the chemical being pulled and injected straight into the water/fluid system, while bypassing the mixing chamber and motor unit. As our customers have discovered, the remote injector kit in some applications extends the life of the injector motor and allows multiple injections within the water/fluid series.

The Remote Bypass kit attached to your injector should be used—

•  In a series, when multiple chemicals are injected into a water/fluid system. Each injector adds chemical to the fluid system, while bypassing the next injector and eliminating the potential damage to that injector.

• To increase the effectiveness of the primary chemical such as fertilizer or chlorine. In a series, the second injector will dispense the primary chemical. The first injector with the remote injector kit attached can be used to control alkalinity or ph with the goal of achieving maximum efficiency of the primary chemical. See Remote Bypass Kit diagram

• To prevent mineral buildup within the motor unit. Chemicals like chlorine will cause mineral buildup, so it is better to inject it directly into the water system using the remote injector kit.

• And finally, to prevent injector motor damage when injecting aggressive chemical.

Remember: when mixing more than one chemical, always refer to your chemical manufacturer information guide for proper application.

Fall Fertilization A Sound Agronomic Practice

Troubleshooting tip #2; if the injector is clicking but not pulling solution.

First inspect the exterior, is the suction tube filter clean? If the filter is clogged, clean and replace. If the filter is clear then check the suction tube itself for cracks and replace if necessary.

If the suction tube is free of cracks or clogs then you may need to clean the suction tube fitting. To do this remove the Interlock Pin (#79 in your manual) and carefully pull out the inner cylinder. Then unscrew the suction tube fitting from the inner cylinder and clean and rinse, replace any damaged parts.

If this does not solve your problem then you would need to unscrew the external cylinder, separating if from the body of the injector. Take hold of the shaft and turn it 90 degrees in any direction to release it and pull the shaft from its housing. Remove the dosage piston and clean and inspect O-rings. To reinstall the dosage piston it is important that the thinner lips of the dosage piston be pointed up before reattaching to shaft.

Clean, dry and inspect inside the inner cylinder for scratches or cracks. If damaged, replace the inner cylinder.

You can now reassemble your lower end and the injector should now be clicking. If you need further assistance please feel free to contact our technical services department at 800-344-6767.

Injector is not clicking

Dosmatic has deemed October...Troubleshooting month. Each week we will post a different scenario and provide you the information necessary to repair your injector and get you back up and running!

If your injector is not clicking the following are some simple items you can check on your injector.
1.Check that the red plugs are removed.
2.Be sure water flow is in the direction of the arrow on the body of the injector.
3.Be sure the operating pressure is not exceeding the models maximum pressure allowance.
4.Check the lower end to make sure your #17(see manual for location) O-ring is not leaking.
You can also check that your main piston assembly is not worn, if you have wear in this location we recommend you place a minimum of 104 micron inline filter prior to the injector. In addition to these items you may need to also check the cover or main body for wear. This to will need to be replaced and will be eliminated with the use of an inline filter. Finally if you do not find fault in any of these locations check your upper and lower poppets, be sure they are seated on the poppet arms and are not damaged. If you find these poppets are not seated and/or are damaged replace all poppet assemblies.

Come back next week for more troubleshooting tips.
