Plunge All-In Commercial Auto Doser Water Management

You will need:

  • Sirona Chlorine Test Strips
  • Sirona Alkalinity Up
  • Sirona Calcium Booster
  • Liquid Chlorine 10-12.5%
  • Swimming Pool Muriatic Acid Balancer (14.5% Hydrochloric Acid)



Water Balancing - Set up (After Filling the Tub)

This will need to be performed every time you empty and refill the tub. 

 

Step 1: Take the test strip and place it in the water for 2 seconds (directions on test strip tube).

Shake once to remove excess water and read immediately. 

 

Step 2: Ensure the Auto Doser red ball valves are open and the Plunge is on with the pump running. 

 

Step 3: Water Balancing

Total Hardness
Test Strip Reading Action
0-49 Add 3 Tbsp of Calcium Booster
50-99 Add 2 Tbsp of Calcium Booster
100-249 Add 1 Tbsp of Calcium Booster
250+ No action required

 

Alkalinity
Test Strip Reading Action
0-39 Add 4 Tbsp of Alkalinity Up
40-79 Add 2.5 Tbsp of Alkalinity Up
80-119 Add 1 Tbsp of Alkalinity Up
120+ No action required

 

Step 4: Let the unit run for 3 hours to balance the chemicals and get to temperature.
Note: The longer you let it sit the more stable the water will become. 

 

Chlorine and pH Management:  Routine Testing

Recommended Schedule: Test 1x per day before use.

 

Disclaimer: The recommended ranges and target levels are subject to your local jurisdiction’s rules and regulations governing pool and spa water maintenance.

 

Step1: Take the test strip and place it in the water for 2 seconds (directions on test strip tube).

Step 2: Check the Free Chlorine (FCI)

 

Recommended Ranges

Target: 1-3 PPM

Min: 1 PPM

Max: 10 PPM

 

Action:

<1 PPM:

  • Ensure that the Chlorine reservoir is not empty. If empty, fill and retest in 3-5 Hours
  • If the Chlorine reservoir is above the Min line, increase ORP setpoint of Hanna BL121 by 25mv (see setpoint adjustment). Retest in 3-5 hrs.

 

1-9 PPM: No action necessary.

 

>10 PPM: drain some water (3-5 gal) from the tub and add water to the tub as necessary.

 

Note: If tub exceeds 10 PPM consistently, see set point selection and adjustment help center article.

 

Step: 3 Check the pH of the tub

 

Recommended Ranges:

Target 7.35 pH

Min: 7.10 pH

Max: 7.80 pH

 

Action:

<7.10 pH: Add 1 Tbsp of Alkalinity up. Retest in 3-5 Hrs

 

7.11-7.80 pH: No action required

 

>7.80 pH: 

  • Ensure that your pH reservoir is not empty. If below min line, refill reservoir and retest in 3-5 hours.
  • If pH reservoir is above the Min line: drain some water (3-5 gal) from the tub and add water to the tub as necessary. 

 

Note: If tub exceeds 7.8pH consistently, see set point selection and adjustment help center article.
