Read First Before Setting Up Your Plunge

Please read the Safety Precautions  and Warranty before setting up the Evolve Pro Chiller.

After unpacking please allow the Evolve Chiller to sit for 20 minutes to allow the coolant to settle. 

 

Please check the package to make sure you have the following items:

  • 5 x  white zip ties
  • 2x  ¾” straight Compression coupler 
  • Insulated flex hose - 42” (connect chiller to above the water pump)
  • Insulated flex hose - 42” w/ offset union to Chiller (connect chiller to above the filter elbow)
  • 5/16” Black Rubber Ozone Cap 

What You Will Need to Complete the Upgrade:

  • Flex hose cutters (non ratcheting)
  • Tape Measure
  • Hex bolt screwdriver - 5/16” - 8mm
  • Dry Erase Marker or Painter’s Tape to mark measurements
  • Scissors

Location Requirements:

We’re so excited for you to experience the improved experience with the Evolve Pro Chiller! Please note that the location requirement dimensions are very different from the original set up. 

Please follow the location requirements below for the best experience and to protect your Plunge from damage. 

As you follow the set up steps below, you will be removing the original chiller and replacing it with the Evolve Pro Chiller. 

The Evolve Pro Chiller will be placed on the short end of the tub as pictured below. This means that the total length of space needed will increase, compared to the original set up. 

For full dimensions, please refer to  the photo below. 

When you place the Evolve Pro Chiller you want to make sure there’s at least 16 inches of clearance between the chiller fan and the wall to allow for ventilation. Not doing so will damage the chiller and void your warranty. 

End Result:

 

Prepping Your Tub

Step 1: Power Down the Plunge

  • Turn the Plunge off by unplugging the electrical box from the wall.  
  • Unplug the chiller from the electrical box.

Step 2: Drain the Tub and Disconnect the Chiller Connections

  • Find the external drain located below the electrical box and connect a garden hose.
  • Turn the drain valve parallel to the tub to allow the water to drain out.
  • Once the tub is empty, turn the drain valve perpendicular to the tub to close the drain valve. 
  • Then, disconnect the chiller connections.

 

Step 3: Drain Chiller

 

 

Step 4: Remove Inkbird Thermostat (Hot/Cold Units Only)

  • Using a 5/16” Hex bolt screwdriver remove the four screws that are mounting the Inkbird outlet to the inside of the electrical box.
  • Using a phillips head screwdriver remove the inkbird controller that’s mounted to the right side of the electrical box by unscrewing the one screw at the top and then pulling it off. There is double stick tape on the back of the inkbird, so you may need to pull harder to remove the controller. 
    • NOTE: Once the Inkbird is removed, replace the screw to seal the hole. Not doing so may result in water damage to electronics.

Step 5: Unplug Everything

  • Using the scissors, carefully cut the zip tie off. 
  • Unplug the light, water pump, ozone, and inkbird (hot/cold units only) from the power strip inside the electrical box. 

Step 6: Unplug or Cut the Inkbird Probe

  • There is a small wire from the inkbird to the probe on the side of the PVC manifold. 
  • To unplug the probe you can just pull it straight out. 
  • If the manifold is too close to the electrical box to pull straight out, you can use your scissors to cut it. 

Option 1:

Option 2:

Step 7: Remove Ozone Tube and Cap the Venturi

  • Remove the 10mm clear tube from the barbed fitting on the Inline venturi located above the filter.
  • Remove the remainder of the 10mm clear vinyl tube from the barbed fitting on the ozone generator.
  • Discard the vinyl tube
  • Place the black rubber cap over the barbed fitting on the inline venturi located above the filter.

Step 8: Put the Water Filter in Bypass

  • If you have the blue Culligan filter follow these instructions:
    • On top of the filter turn the blue diverter a quarter turn counter clockwise using the handle of the filter wrench.
  • If you have the white GE filter follow these directions: 
    • Pull the white valve located on the left hand side of the filter towards you.The valve will be pointing away from the tub when in bypass mode. 
  • Now you can use the filter wrench to open the filter housing to remove the filter and dump out the water. You do not need to reinstall the filter housing. 

 

Setting Up the Evolve Pro Chiller

Step 1: Chiller Placement

  • Make sure the Plunge and the Chiller are on a solid, flat, waterproof surface.
  • Locate where the chiller connections will connect to the tub.
  • Place the chiller on the end with the circular fan / UI facing out. 
  • The chiller should sit about 5 inches away from the tub
  • Make sure there are at least 16 inches between the circular chiller fan / UI and the wall to allow for ventilation. Not doing so will void the warranty for the Evolve Pro Chiller. 

Step 2: Measure and Cut Filter Housing Piping

  • Stretch the flex piping coming from the original Plunge’s filter housing manifold (please refer to photo or video) and take your tape measurer to measure 18 inches from the fixed end down the flex hose. 
  • Mark the measurement with a dry erase marker or piece of tape. 
  • Grab the flex hose cutters and cut the original Plunge’s piping at the mark you made. Note: Do your best to make a straight cut. 
  • Once the pipe is cut, take your scissors and cut approximately 2 inches of the insulation off the end of the piping.

Step 3: Measure and Cut Pump Piping

  • Stretch the flex piping coming from the original Plunge’s pump (please refer to photo or video) and take your tape measurer to measure 18 inches from the fixed end down the flex hose. 
  • Mark the measurement with a dry erase marker or piece of tape. 
  • Grab the flex hose cutters and cut the original Plunge’s piping at the mark you made. Note: Do your best to make a straight cut. 
  • Once the pipe is cut, take your scissors and cut approximately 2 inches of the insulation off the end of the piping.

Step 4: Tub Measurement

  • To the left of the water filter housing measure from the top of the tub down 6 inches. 
  • Mark that spot with a dry erase marker or piece of tape. 
  • This measurement will be the marker for the height where your new and old connections meet. 

Step 5: Connect Evolve Pro Chiller Connection A (Shorter Elbow)

  • Find the connection for the Evolve Pro Chiller labeled “A”. Connection A will be coupled to the pump piping on the original Plunge. 
  • Check to make sure the black O-ring is seated in the connection collar and connect it to the A port on the chiller.

Please make sure the threading is on straight and not cross threaded. Cross threading can damage the connection collars. 

Step 6: Connect Evolve Pro Chiller Connection B (Longer Elbow)

  • Find the connection for the Evolve Pro Chiller labeled “B”. Connection B will be coupled to the filter housing piping on the original Plunge. 
  • Check to make sure the black O-ring is seated in the connection collar and connect it to the B port on the chiller.

Please make sure the threading is on straight and not cross threaded. Cross threading can damage the connection collars. 

Step 7: Cut Connection A

  • Grab connection A and the piping coming from the pump and place them against each other at the 6 inch mark you made on the tub. 
  • Where they meet, using the flex hose cutters, cut connection A to the length of the piping from the pump.
  • Using your scissors cut the insulation back approximately 2 inches.

Step 8: Couple Connection A and Pump Piping

  • Grab the white coupler and unscrew one end. You should see a black o-ring come out. 
  • Take the couple coller and please it over the end of connection A.
  • Then take the black o-ring and put it on the end of connection A.
  • Grab the white couple and screw it onto the connection.
  • Do the same on the piping coming from the pump.
  • Make sure both sides are screwed on tight and there is no cross threading.

Step 9: Cut Connection B

  • Grab connection A and the piping coming from the filter housing manifold and place them against each other at the 6 inch mark you made on the tub. 
  • Where they meet, cut connection B to the length of the piping from the filter housing manifold.
  • Using your scissors cut the insulation back approximately 2 inches.

Step 10: Couple Connection B and Filter Housing Manifold Piping

  • Grab the white coupler and unscrew one end. You should see a black o-ring come out. 
  • Take the couple coller and please it over the end of connection B.
  • Then take the black o-ring and put it on the end of connection B.
  • Grab the white couple and screw it onto the connection.
  • Do the same on the piping coming from the filter housing manifold piping.
  • Make sure both sides are screwed on tight and there is no cross threading

Step 11: Ziptie the Piping Together

  • Make sure there’s no strain on the piping in any direction. 
  • Bring both pipings together and add two to three zip ties to secure them in place.

Step 12: Fill the Plunge

  • You can begin filling the Plunge using the carbon hose filter. 
  • As the Plunge is filling with water you can move on to the next step.
 

Step 13: Plug Back In the Original Plunge Light

  • Find the plug for the light that comes out of the side of the tub below the electrical box. 
  • Plug it back into the power strip inside the electrical box using the top outlet.

Step 14: Plug In the Original Plunge’s Pump

  • Find the plug that goes to the original Plunge’s pump
  • Plug it in below the light plug on the power strip.

Step 15: Plug In the Evolve Pro Chiller

  • Once the tub is filled past the jet line, you can plug in your Evolve Pro Chiller to the electrical box on the original Plunge. This will allow you to use the underwater light. 
  • Then you can plug the original electrical box into a dedicated 15 amp Circuit (120V). 
  • Note: Ensure the Evolve Pro Chiller has rested for at least 20 minutes for the coolant to settle before plugging it into the outlet.

Step 16: Turning the Plunge On

  • Locate the two buttons on the power cord that say “test” and “reset.” 
  • Press the “reset” button to turn it on. 
  • You should hear the jets turn on and see the screen on the back light up with the current temperature. 

Note: The jets may not turn on right away and you’ll hear the pump priming when you first turn it on. This is normal and you can let the chiller go through its priming process for a few minutes. 

Step 17: Set Your Temperature

  • Press the up and down arrows on the back of the tub to set your desired temperature. 
  • The blue arrow indicates cooling, and the red arrow indicates heating. 

Step 18: Operate Light

  • The light can still be operated by the silver button on the side of the Plunge.  

Note: The light button on the Evolve Pro Chiller UI and in the app cannot be used to operate the light. 

 

Step 19: To Pause the Jets

  • For a quieter Plunge experience, you can pause the jets by pressing the pause button. 
  • It will pause in increments of 15 minutes up to an hour. 
  • Once the timer runs out, the jets will turn back on and resume circulating the water. 

Step 20: Water Maintenance 

  • Any products you received in previous maintenance kits will still work to maintain the cleanliness of your Plunge. 
  • The only item you will need to replace are the filters. Please go here to purchase the correct filters.
  • The filters used in your First Generation Plunge are not compatible with the Evolve Pro Chiller.

Step 20: Continue to take the Plunge, and change your life!

  • Thank you for continuing to choose Plunge! We appreciate you!
