Bu qanday ishlaydi

The Dosatron D40MZ2 operates on a simple, water-powered principle to ensure accurate and consistent chemical injection:

1. Water flow initiates the process.
2. Water enters the Dosatron body, activating the internal piston.
3. The piston pulls the concentrated chemical solution up from the supply tank.
4. The concentrate mixes precisely with the incoming water inside the Dosatron.
5. The blended solution is then discharged into the main water line at the set dilution rate.

O'rnatish

For optimal performance and safety, ensure proper installation of your Dosatron D40MZ2 unit. It is recommended to install the unit in a bypass line to allow for maintenance without interrupting the main water flow.

• Install the unit vertically with the suction hose pointing downwards.
• Barcha ulanishlar xavfsiz va oqmasligiga ishonch hosil qiling.
• Connect the suction hose to the chemical concentrate tank.
• Verify that the water supply is within the specified pressure and flow ranges.

Refer to the detailed installation guide provided with your product for specific plumbing configurations and best practices.

Operatsiya

The Dosatron D40MZ2 allows for easy adjustment of the dilution setting to meet your specific application needs.

1. Identify the desired dilution percentage or ratio for your application.
2. Locate the adjustment sleeve on the lower part of the injector.
3. Rotate the adjustment sleeve to align the indicator with your desired setting on the scale.
4. Ensure the setting is locked into place to prevent accidental changes.

Always verify the actual dilution rate by testing the output solution, especially when precise chemical concentrations are critical.

Muammolarni bartaraf qilish; nosozliklarni TUZATISH

This video provides guidance on how to troubleshoot common issues with your Dosatron D40MZ2 injector.

Umumiy muammolar va echimlar:

The three key areas to troubleshoot are:

1. The injector is clicking but not drawing the concentrate.
2. The injector is clicking but water is going down into the tank.
3. The injector isn't clicking.

The first two issues often originate in the stem area.

Troubleshooting Steps for Stem-Related Issues:

1. Check for Suction: While the unit is installed and water is on, remove the suction hose nut and suction hose. Check for suction on your finger. If no suction is felt, turn off the water.
2. Bo'shatish bosimi: Release pressure by pressing the air bleed button on top of the Dosatron unit.
3. Disconnect Suction Hose: Unscrew the hose nut and remove the chemical pickup hose.
4. Stolni olib tashlash: Unscrew the injection stem nut and pull the stem straight out from the injector body. Set the injection stem aside.
5. Inspect Plunger Seal: Remove the plunger by twisting it a quarter turn counterclockwise and pulling it out. Hold the plunger and inspect the seal for nicks, grooves, or wear. Test the plunger seal by inserting the plunger down into the stem. When pulled out, it should make a pop sound. If it doesn't pop or if you see damage, replace the plunger seal (Part Number: #JDI121). To change, roll the old seal off and install a new one.
6. Tekshirish valfini tekshiring: Pick up the black stem. Unscrew and remove the check valve nut. Pull the check valve straight out. Set the stem aside and grasp the white retainer, twisting it a quarter turn counterclockwise to release the check valve parts. Inspect all parts (cone, spring, guide) for damage, gumminess, stickiness, or missing components. If parts are dirty, clean and reinstall. If damaged or missing, replace them.
7. Reassemble Check Valve: To reassemble, put the cone into the top of the barb. Slide the spring over the shaft and position the top guide over the shaft. Align the guide and twist it a quarter turn clockwise to lock. Give it a tug to ensure everything is in position. Reinstall the check valve assembly into the stem. Then reinstall the check valve nut.
8. Reattach Plunger: Pick up the piston and plunger and reattach the plunger onto the lower end of the piston by twisting it clockwise to lock.
9. Inspect Suction Hose: Take a look at the top of the suction hose. If it flares out, cut an inch or so off and reinstall. If the suction hose is cracked, rigid, or looks old, replace it.
10. Reinstall Suction Hose: Thread the suction hose nut onto the hose. Slide it onto the barb and hand tighten the nut.
11. Reset Desired Dosage: Make sure you reset your injector to the desired setting.

Troubleshooting Steps for Non-Clicking Injector:

1. Remove Bell Housing: If the injector isn't clicking, use a strap wrench to loosen the blue bell housing. Then remove the bell housing and pull the piston straight out.
2. Inspect Piston Flanges: Visually inspect the upper and lower flanges on the piston shell (Upper Flange Part Number: #PDI1093, Lower Flange Part Number: #PDI1092). If they are worn or have scratches, the flanges will need to be replaced.
3. Fit Test Flanges: Another way to check the flanges is by doing a fit test.
   • To test the upper flange, invert the piston and insert it into the blue bell housing. It should have a uniform snugness.
   • To test the lower flange, remove the plunger by turning it a quarter turn counterclockwise and pulling it straight out. Now insert the piston into the body. It should have uniform snugness.
   If either is loose, the flanges need to be replaced.
4. Replace Upper Flange: To replace the upper flange (Part Number: #PDI1093), locate the release lever, press it down, and rotate the lock ring counterclockwise. Remove the lock ring and piston flange by lifting straight up. To install the new upper flange, locate the square and open edges. Then slide the flange over the upper portion of the piston shell with the square edge facing upward. Align the white tooth inside the lock ring with the black lever in the piston shell. Press it down into place and twist clockwise until it locks.
5. Replace Lower Flange: The procedure is similar for the bottom flange. To replace the lower flange (Part Number: #PDI1092), locate the release lever. Press it down and rotate the lock flange clockwise. Remove the lock ring and piston flange by lifting straight up. To install the new lower flange, locate the square and open edges. Then slide the flange over the lower portion of the piston shell with the square edge facing downward. Align the white tooth inside the lock ring with the black lever in the piston shell. Press them down into place and twist counterclockwise until it locks.
6. Reinstall Piston and Bell Housing: Reinstall the plunger into the piston by aligning the top with the retainer. Press the plunger in and turn it a quarter turn clockwise to lock. Place the piston back into the body and reinstall the blue bell housing hand tight.
