Tubs Compatible With These Instructions:

• Plunge All-In Commercial + Auto Doser
• Plunge All-In Commercial Max

Items Needed:

• Chemical Safe Gloves
• 2 Chemical Safe Cups 
• Towel
• Recalibration Chemical Kit Packets 
  • One Red Packet (pH 4.01)
  • One Green Packet (pH 7.01)
  • One Black Packet (470 mV ORP Test Solution)

Instructions:

1. Pause the tub for at least 45 minutes. (This process should only take around 15 minutes, but err on the side of caution)
2. Close both colored ball valves below the auto doser controller. 
3. Remove the silver connection collar from the auto doser controller that connects the auto doser probe to the controller. (The purpose of taking it on and off through this process is to make sure not to tangle and twist the wire)
4. Unscrew the auto doser probe with the cup underneath it to catch excess water. 
5. Set the auto doser probe in the cup you have on hand or propped in the skimmer so the auto doser probe remains wet. The probe cannot be left out of water for more than 15 minutes.
6. Re-connect the silver connection collar to the auto doser controller.

Calibrate pH 

1. Starting with the 4.01 Solution (Red Packet)
2. Press “Menu” on the auto doser controller 
3. Scroll to “pH options” on the screen.
4. Press the left blue circle button underneath “CAL” to select it. (CAL stands for "Calibrate")
5. Grab the probe and shake the excess water off.
6. Open the 4.01 pH packet and place the probe into the packet, fully submerging the end in the solution.
7. Empty the water cup
8. Place the probe upright and steady in the packet in the cup until the reading on the controller screen stabilizes and you see “CFM” which stands for “Confirm” show up and does not disappear.
   • "CFM" will pop up on the lower right hand corner of the screen.
   • Please note: Stabilization should take approximately 1-2 minutes. The reading should be close to 4.01 (+/- 0.95). 
   • If the reading does not stabilize and a different error appears, please submit a ticket on our contact form. 
9. Press the right blue circle button under “CFM” once it appears and does not disappear. 
10. Refill the cup with water from the tub. 
11. Remove the probe and rise it off and then place the probe back into the cup of water.
12. You should see the screen change to begin stage two of the calibration process using the 7.01 pH solution (Green Packet).
13. Open the 7.01 pH packet and place the probe into the packet, fully submerging the end in the solution.
14. Empty the water cup
15. Place the probe upright and steady in the packet in the cup until the reading on the controller screen stabilizes and you see “CFM” which stands for “Confirm” show up and does not disappear.
    • "CFM" will pop up on the lower right hand corner of the screen.
    • Please note: Stabilization should take approximately 1-2 minutes. The reading should be close to 7.01 (+/- 0.95). 
    • If the reading does not stabilize and a different error appears, please submit a ticket on our contact form. 
16. Press the right blue circle button under “CFM” once it appears and does not disappear.
17. Refill the cup with water from the tub. 
18. Remove the probe and rise it off and then place the probe back into the cup of water.
19. Once both pH calibration stages are done, it will say “calibration complete” and go back to the list of options. 

Calibrate ORP

1. Check your tub timer to make sure you still have adequate time left (at least 30 minutes)
2. Scroll to “ORP Options” on the screen.
3. Press the left blue circle button underneath “CAL” to select it. (CAL stands for "Calibrate")
4. Open the black 470 mV ORP Test Solution packet and place the probe into the packet, fully submerging the end in the solution.
5. Empty the water cup
6. Place the probe upright and steady in the packet in the cup
7. While the probe is stabilizing use the up and down arrows to change the ORP calibration point to match the packet at 470 mV.
   • Please note: If you press and hold the arrows, it will rapidly move the mV number up or down, it may start high in the 1000s. 
8.  Once the reading on the controller screen stabilizes and you see “CFM” which stands for “Confirm” show up and does not disappear.
   • "CFM" will pop up on the lower right hand corner of the screen.
   • Please note: Stabilization should take approximately 1-2 minutes. 
   • If the reading does not stabilize and a different error appears, please submit a ticket on our contact form. 
9. Press “CFM”.

Once Calibration Is Completed

• Press “Menu”
• Remove the silver connection collar from the auto doser controller.
• Rinse the probe off in the tub water.
• Install the auto doser probe back into its original location in the PVC injector manifold following initial install instructions. 
• Re-connect the silver connection collar back into the auto doser controller. 
• Once the probe is secured, open the colored ball valves again to allow water flow into the injector manifold.
• Unpause the tub.
• Turn the auto doser controller off and back on again using the rocker switch on the left hand side of the controller to reboot the system. 
• Dispose of the open chemical packets in the trash.

Follow the water management instructions and allow the Plunge to run for at least 3 hours to re-stabilize before allowing anyone to use it. 

How to Confirm Successful Recalibration:

1. Grab your test strips
2. Test the water by placing the test strip in for 2 seconds and then gently shake off the excess water
3. Determine pH by using the table on the test strip bottle 
4. Compare the test strip pH to the auto doser pH. 
5. If your readings are close to each other, then you know you recalibration was successful. 
   • If the reading is significantly different please submit a ticket on our contact form.
