Set Up & Maintenance

Tub Assembly

Step 1: Prior to placing the tub, ensure that the area is clean and free of any sharp objects that may puncture the tub.

Step 2: Take the tub out of the bag and unroll it to gain access to the air valve.

Step 3: Remove the air valve cover, press and test the air valve to ensure it is in the up position. If the valve is in the down position, the tub will not hold air, so double-check its position.

Step 4: Attach the hose to the electrical pump's inflation side, then lock it into the tub by turning it clockwise.

Step 5: Inflate the tub and cover until it reaches 10 PSI, the electric pump will get to 85% full in 4-6 minutes. Top it off with manual pump.

Step 6: Once the tub is inflated, remove the pump hose and screw the valve cover back in place. If air comes out after removing the hose, the valve may be in the incorrect position.

Step 7: Follow continued instructions to fill and operate, then ENJOY!

Chiller Assembly

Step 1: Start by rotating the Chiller Fitting Caps counterclockwise to remove the protective covering. Next, install the Inner Water Strainer by turning it clockwise onto the red "Inlet" fitting located on the Chiller. Confirm that the O-ring (washer) near the Chiller body is properly positioned. Place the silver Water Strainer Cover over the Inner Water Strainer and hand tighten it by hand until it is snug, ensuring that the enclosure is flush with the Chiller body.

Step 2: Prior to connecting the hoses, verify that each end of the Hose Connection Fittings contains a Hose O-Ring. If any o-ring is missing, retrieve one from the spare parts bag to prevent leakage. Connect the green "Water In" fitting on the Tub to the green "Outlet" on the Chiller. Likewise, connect the red "Water Out" fitting on the Tub to the red "Inlet" on the Chiller. To secure the connection, thread on the Hose Connection Fittings and rotate them clockwise. The threads should tighten smoothly and effortlessly. If you encounter immediate resistance, attempt attaching the hose again. Hand tighten the fittings until you feel resistance. Please remember that the Hose Connection Fittings should only be tightened by hand, without the use of tools. Over-tightening may lead to leaks or damage.

Step 3: Ensure hoses are properly in place. Remove the plastic covering and insert a filter into the Water Filter Housing. Fill the Water Filter Housing with water. Confirm that the Filter Housing O-Ring is securely positioned in the Upper Water Filter Housing. Attach the Lower Water Filter Housing by turning it to the right, facing the back of the Chiller, until it is hand tight. It is important not to use the filter wrench to tighten the water filter housing, as the wrench is only meant for loosening. Now, you can proceed to fill the Tub with water up to the designated "MIN/MAX" line.
Note that overfilling may cause water to overflow from the Tub. However, you have the flexibility to fill the Tub according to your personal preference.

Filling the Tub

Step 1: Make sure your tub is in the desired location before starting to fill, as it will be very heavy after filling.

Step 2: Fill the tub with water using a garden hose if available, or use a garden hose faucet adaptor to connect to a bathroom sink (not included).

Step 3: While filling the tub, monitor for any leaks. If you have a leak please stop filling and contact us immediately. You can contact our team by emailing us at support@therasage.com or call 888.416.4441

Step 4: Fill the tub to 80-90% based on your weight. For commercial use, consider filling on the lower side to accommodate different body sizes. You want the water up to at least neck level.

Step 5: Once the water level reaches the above minimum mark, you can proceed with turning on the Chiller.

Step 6: Do not fill over the water max line.

Maintenance & Cleaning 

INSIDE: Once you have drained the tub, wipe it down with a soft cloth and liquid soap.

OUTSIDE: Can be wiped down more often depending if the tub is located outside or inside. Again, wipe down with a soft cloth and liquid soap.

Filter Maintenance

  • Clean filter and skimmer as needed, checking the flow meter will be a good indication that its time to service the unit.
  • Use the plug provided to plug the water out hole at the tub's base.
  • Open the filter cartridge housing and remove the water. Take the filter to an area with high pressure nozzle to rinse it thoroughly up and down, clearing the debris from the pleats.
  • Place the filter back in the housing and screw it tightly in place, ensuring all rubber seals are in place.
  • Remove skimmer housing and skimmer, clean the skimmer and put back into place.
  • Remove the plug from inside the tub and turn the chiller back on.

    Remember to replace the filter element every 1-2 months or as per use and water quality. If there is low water flow and/or flashing filter signal on the Chiller, clean or replace the filter and skimmer.
