Plunge All-In Commercial Max Water Management

Tubs Compatible With These Instructions:

  • Plunge All-In Commercial Max

You will need:

Sirona Chlorine Test Strips

Sirona Spa Up

Sirona Calcium Booster

Liquid Chlorine (10% Sodium Hypochlorite)

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 in bright sunlight or LED light. Reading a test strip in a dimly lit room will cause misreadings and incorrect dosing. 

Step 2: Ensure the auto doser 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 2 Tbsp of Calcium Booster
50-99 Add 1 Tbsp of Calcium Booster
100-249 Add 2 Tsp of Calcium Booster
250-350 No action required
350+ Use an ion exchange filter to strip calcium and hard minerals from the water before filling the tub. 
High total hardness (calcium and mineral) content can build up in the components and cause damage. 

 

Alkalinity
Test Strip Reading Action
0-39 Add 4 Tbsp of Spa Up
40-79 Add 2.5 Tbsp of Spa Up
80-119 Add 1 Tbsp of Spa Up
120+ Manually dose muriatic acid 1x and wait 30 minutes before retesting and dosing the unit again

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. 

 

Auto Doser Reading Information: 

Look at the Auto Doser Controller screen and follow directions below: 

Auto Doser pH and ORP reading is fluctuating up. No action required. Allow the auto doser to stabilize the water.
Auto Doser pH and ORP reading isn’t fluctuating at all and no chemicals can be seen coming through the clear tubing. Please read the instructions on how to prime the lines of the auto doser in the help center. 

Chlorine and pH Management: Routine Testing

Recommended Schedule: Test 1x per day before use.
