SETUP INSTRUCTIONS

SETUP: Detailed setup video can be found here. https://youtu.be/w4vK- Zsls98.

STEP 1) UNBOX YOUR CULTURE CHILLER AND TUB
- Remove the Chiller and Tub from their shipping cartons. We recommend keeping the Chiller box for future transportation needs. Select a flat, clean, and smooth surface. A water source and 120v power source should be accessible. If outdoors, we recommend setting the tub up in a sheltered area for the longevity of your product. If using a Coldture Premium Mat, (sold separately) first place the mat down and unfold the Tub in the desired orientation.
STEP 2) INSTALL THE VALVE FITTINGS
- Add one of the large round washers over the 3/4 side ball valve. Attach the Valve Fittings to the Tub “water out” (red), and “water in” (green) fittings by rotating it clockwise until hand tight. Do not tighten with tools.
STEP 3) INFLATE THE TUB
- Inflate the Tub with the Double Action Air Pump. Ensuring the hose is connected to the “Inflate” side of the pump. Open the Inflation Valve on the Tub by rotating it counterclockwise. The Inflation Hose connects to the Inflation Valve with a quarter turn clockwise. When inflating the Tub, check to ensure that the Inflation Valve Pin is in the depressed (out) position or the air will be released after the hose is detached. Inflate until the gauge reads 10 PSI. Do not over-inflate or product damage will occur. Replace the Inflation Valve cap with a clockwise turn.
STEP 4) INSTALL THE EXTERNAL WATER STRAINER
- Remove the Protective Cap of the red “Inlet” fitting on the Chiller by rotating counterclockwise. Install the Inner Water Strainer into the red “Inlet” by turning clockwise. Next, install the silver Water Strainer Cover. This fits over the Inner Water Strainer and should be screwed to hand tight.
- SETUP: Detailed setup video can be found here. https://youtu.be/w4vK-Zsls98.
STEP 5) CONNECT THE CHILLER TO THE TUB
- First, check that there is a Hose O-Ring inside each of the four Hose Connection Fittings. If not, place an o-ring from the spare parts bag. Connect the 90-degree hose side to the tub. The green “Water In” fitting on the Tub should connect to the green “Outlet” on the Chiller. The red “Water Out” fitting on the Tub should connect to the red “Inlet” on the Chiller. To tighten, thread on the Hose Connection Fittings and rotate clockwise. The threads should tighten easily and smoothly. If resistance is felt, try attaching the hose again. Hand tighten only. Over-tightening may cause leaking or damage.
STEP 6) FILL THE TUB
- Check that the Chiller Drain Cap and hoses are in place. Remove the Lower Water Filter Housing, insert a filter, and fill it with water. Ensure the Filter Housing O-Ring is in place in the Upper Water Filter Housing. Install the Lower Water Filter Housing by turning right if facing the back of the Chiller until hand tight. Do not use the filter wrench to tighten the water filter housing (for loosening only). The Tub can now be filled with water up to the “Max Level” line. Overfilling may cause water to overflow from the Tub for some users, though you may fill to your preference.
STEP 7) OPEN VALVES
- Once the Tub has been filled, confirm the Tub Valve Fittings are in the open (parallel) position. Ensure this step has been completed to prevent damage to the Chiller!
STEP 8) POWER ON THE CHILLER
- Plug the Chiller into a standard 120v grounded power supply with a 15 amp minimum circuit and test the GFCI functionality. To perform the test, first ensure the Power Switch on the back of the Chiller is up in the “on” position and then press the orange “T” Test Button above the Power Switch. The Power Switch should flip to the down “off” position. Now flip the Power Switch back up to the “on” position. If this test does not cause the Power Switch to turn off, do not proceed, and contact support for assistance. Place the Power Plug in an elevated position off the ground and away from water. Do not handle it with wet hands. You may now turn on the Chiller by pressing the “Power On” button on the display screen. The Chiller may take up to 2-3 minutes to purge air from the system and will flash “o1.x” or “02. x” while purging. Once this has been completed, this code will change to the current water temperature and the Chiller will begin cooling or heating. If the “FL” (Flow) error appears, or if this step takes longer than 2-3 minutes, check that the Valves are open and that the hose connections and filter housing are connected properly, and then repeat this step.
- SETUP: Detailed setup video can be found here. https://youtu.be/w4vK-Zsls98.

STEP 3) DRAIN THE TUB

There are three methods that can be used to drain the Tub:

A. Disconnect the red “Water In” hose from the Chiller. Direct the hose to the desired area for drainage and open the valve. Water will flow out of the hose until it reaches the Lower Water Fitting. The remaining water can be removed by turning the tub over.
B. Disconnect both hoses from the Tub. The red “Inlet” hose from the Chiller should be placed inside the tub. The green “Outlet” hose from the Chiller should be directed to the desired location for drainage and the Chiller can be turned back on. The Chiller will pump water out. The Tub can be tipped as the water level gets low to remove the last bit of water. Be sure to turn off the Chiller immediately when the Tub has been drained to avoid damaging the Chiller.
C. Purchase a submersible Sump pump. Connect your garden hose to the pump and drop the pump into the water. When you plug the pump in, water will begin draining. Please visit our help center or reach out for recommendations on Sump pumps.
STEP 4) DISCONNECT THE HOSES
- Once the Tub is drained, the hoses can be disconnected from the Tub and Chiller by rotating the Hose Connection Fittings counterclockwise, and the Chiller can be unplugged.
STEP 5) DRY THE TUB
- The Tub should now be dried inside and out (including the bottom) with a towel to prevent mildew. This is also a good time to clean the Tub with mild soap and water.
STEP 6) DEFLATE THE TUB
- Remove the Inflation Valve Cap. Press the Inflation Valve Pin to allow the air to be released. The air release will be aggressive so don’t be startled! Remove the remaining air by attaching the Inflation Hose to the “Deflate” side of the Double Action Hand
- Pump. When deflating the Tub, check to ensure that the Inflation Valve Pin is in the depressed (out) position (see image). Deflate until all air has been removed and remove the inflation hose. Replace the Inflation Valve Cap. The Tub Valve Fittings should be removed.
STEP 7) FOLD THE TUB
- The Tub can now be folded for storage. First, fold the Coldture branded wall of the Tub inward. The back wall of the Tub can now be folded over the branded side of the Tub so that the tub is flat. Fold the right side of the Tub towards the center, with the fold being just outside the water fitting, and repeat on the left side. Hold the tri-folded Tub with one hand, and with the other, place the Storage Strap under the Tub. Fasten the Storage Strap and tighten it.

TAKEDOWN COMPLETE

You are now ready to take your adventure on the road!

WATER MAINTENANCE

INITIAL SETUP:

Add 6 grams (1/2 bottle cap) of Oxidizer into water
Wait 15 minutes
Add 4 grams(1/2 bottle cap) of Sanitizer into water
Wait 15 minutes before entry into Tub

WEEKLY MAINTENANCE

SUMMARY:

There’s 3 simple steps for weekly maintenance that take about 15 minutes to ensure that your Tub is running properly and the water is clean and clear.
The first step is checking the water chemistry, then the External Water Strainer, then the Water Filter.

STEP 1) CHECK THE CHEMISTRY

Start by adding 6 grams of Oxidizer for low volume (5 to 7 plunges per week) or 12 grams (1 full cap) for high volume (7+ plunges per week).
Wait 15 minutes.
Immerse the Test Strip to a depth of 6” for 2 seconds. Remove and shake once to remove excess water. Wait 10 seconds and compare to color chart on back of bottle. If Sanitizer shows below the “OK” range, add 2 grams of clorine.. Wait 15 minutes and test again. Repeat test and add more Sanitizer if necessary.
If Alkalinity, pH, or Calcium are outside of desired range, balancers can be purchased through our website. Of these, pH is most important to have in the right range.

STEP 2) CHECK EXTERNAL WATER STRAINER

Turn off the Chiller, and close the Tub Valves by turning the handle perpendicular to the valve body.
Remove the bottom red “Inlet” Chiller Hose from the Chiller. Remove the Water Strainer Cover by twisting counterclockwise and check the Inner Water Strainer for debris; remove any foreign materials present.
Use a Brillo pad or rough sponge if necessary. Check the Strainer O-ring at the base of the threads is present and free from damage before reinstalling Water Strainer Cover.

STEP 3) CHECK WATER FILTER

For optimal filter performance, replace monthly. To access the Water Filter, turn the Lower Water Filter Housing to the left if facing the back of the Chiller.
When changing the filter, empty water from the Lower Water Filter Housing fully and refill up to the top with fresh water.
Ensure the Filter Housing O-ring in the Upper Water Filter Housing (white part) is present and free from damage before reinstalling filter housing.
Be sure to open the Tub Valves before turning the Chiller back on, or damage will occur!

RECOMMENDED ROUTINE MAINTENANCE

To ensure the longevity of your Coldture Tub, it is recommended to perform maintenance on your Chiller and Tub regularly.
This maintenance protocol will help ensure that fthe Chiller functions as expected and that the water quality of the Tub is kept clean. The steps below should be performed every three months.

TUB

Disconnect the Tub from the Chiller.
Drain all water from the Tub and Chiller Hoses.
Using mild soap and water, wash down the inside and outside of the Tub using a washcloth or soft sponge. Place the Chiller Hoses inside the Tub and run soapy water through them.
Rinse the Tub and Chiller Hoses off with clean water.
Allow the Tub and Chiller Hoses to air dry completely; preferably in direct sunlight.
Any marks or scuffs on the Tub can be removed by lightly scrubbing with a moistened Magic Eraser. Do not scrub aggressively or it may damage the material. Do not use it on any logos or printed areas!
Check the air pressure of the Tub by connecting the Double Action Air Pump and refilling to 10 PSI.
Check the area where the Tub was located for any signs of mildew buildup and clean if necessary. If large amounts of mildew buildup are noticed, the Tub may need to be placed on a material that can breathe to allow water to evaporate.
Refill with water and perform an initial Sanitizer protocol to sanitize the new water.

CHILLER

Descaling

Disconnect the Chiller Hoses from the Tub. Ensure Tub Valve Fittings are in the closed (perpendicular) position if the Tub still contains water.
Place both ends of the Chiller Hoses into a 5 gallon bucket or similar container. Fill with distilled white vinegar (cleaning vinegar) and water at a 1:4 ratio.
Turn on the Chiller and run in heating mode at 40ºC./ 104F. Allow the
- Chiller to circulate water for 30 minutes.
Turn off the Chiller and empty the bucket of water. Refill with clean water.
- Place Chiller Hoses back in the bucket and run the Chiller for another 30 minutes. The descaling process is now complete.

HOUSING MAINTENANCE

With a soft cloth, wipe down the exterior of the Chiller with mild soap and water.
Wipe off all soap residue with a damp cloth.
With the Chiller Off, inspect the fan and remove any debris that may be on or around the fan shroud.

TROUBLESHOOTING

WATER CIRCULATION TROUBLESHOOTING

Step 1) The code o1.x or o2.x is shown on the display at startup and when Chiller is priming with water.
- This screen is normal when establishing water circulation which can take up to 2-3 minutes, especially if the Chiller and/or Chiller Hoses were recently drained of water.
- If after 5 minutes the machine has still not established water circulation, please check each of the following. The Chiller can be tested in between each step:
- A. Ensure that the Tub Fitting Valves are in the open (parallel) position and that hoses are connected without leaks.
- B. Check that the Water Filter and Inner Water Strainer are clean and clear of debris. You can find instructions to replace and clean these parts on our Maintenance Page. It is a good idea to proactively replace the Water Filter even if it looks clean as minerals can block the filter but may not show discoloration.
- C. Check the Hose O-rings on each end of the Hose Connection Fittings. They should be fully seated at the bottom of the threaded fitting and when attached, the connection should only be tightened until a little resistance is felt and the hose no longer wiggles at the connection point. Do not use tools to tighten.’
- D. Remove the Lower Water Filter Housing and ensure that the Filter Housing
- E. Ring in the Upper Water Filter Housing (white part) is present and not damaged. If you have a purple-tinted Lower Water Filter Housing, check that the lower O-ring is present as well. When reinstalling the Lower Water Filter Housing, fill it with water to the top and tighten only until a little resistance is felt. Do not over-tighten or it will deform the gasket and potentially damage the O-rings.
- F. Ensure the Strainer O-Ring on the External Water Strainer is present and not damaged. Replace if necessary from the spare parts kit. The Water Strainer Cover should be hand tightened until it stops.
- If the steps above do not resolve the issue, please move on to the next step.
Step 2) Check Valve (Outlet Port)
- There is a Check Valve inside the outlet port on the Chiller. This can become stuck in the closed position and prevent water from flowing through the unit. If you notice that the Chiller is trying to prime but no bubbles are coming out from the Tub water-in fitting, this is a possible resolution. You will first close the Valves by rotating to the Closed (perpendicular) position. Then Remove the Outlet Chiller Hose and check to see if the little pin in the valve is stuck outward (toward you).
- If it is stuck outward, use a small screwdriver and press on it gently. If it was indeed stuck, you will feel/hear a little click that indicates the Check Valve has returned to position. Reinstall the Chiller Hose, open the Tub valve, and try the Chiller again.
Step 3) Air Trapped in Unit
- If you have recently taken a Chiller Hose off of the Chiller or Tub (For example, to clean the Inner Water Strainer), it is possible that an airlock can be created within the Chiller.
- We will want to release this air lock in the system by loosening the Lower Water Filter Housing. Loosen the housing until it is completely off, fill it up with water to the top, and reinstall.
- If the steps above do not resolve the problem, please contact support@coldture.com so that we can further assist you!

HOSE CONNECTIONS LEAKING:

Check to ensure gasket is in place; Disconnect and reconnect Chiller Hose, ensuring snug hand tight connection; Replace Hose O-Ring with new one.

TUB DEFLATES IMMEDIATELY AFTER INFLATING:

When inflating, ensure that the Inflation Valve Pin is in the depressed (out) position prior to hooking up the Inflation Hose; if unsuccessful, Tub Inflation Valve may be damaged and require replacement.

TUB DEFLATES OVER TIME:

Temperature change may cause air pressure in Tub to change slightly, re-inflate accordingly; If deflation continues regularly, use the air valve wrench, and tighten the valve assembly.
If deflation continues, an air leak may be present. Air leaks can be found by using soapy water to locate the leak, and then the included repair kit can be used to prevent further leaking.

CHILLER WILL NOT TURN ON:

Ensure Chiller is plugged into an active power source and ensure the Power Switch on the back of the Chiller is up in the “on” position. Press the orange “T” Test Button above the Power Switch.
The Power Switch should flip to the down “off” position. Now flip the Power Switch back up to the “on” position. If this test does not cause the Power Switch to turn off, do not proceed, and contact support for assistance.

WATER IS DRIPPING FROM CHILLER:

During heating mode, condensation may develop inside the Chiller in certain high humidity conditions.
A small amount of water drainage from the Chiller is normal in this circumstance; Check Hose Connections are secure and that they are tight and have.
O-Rings in place; Check Water Filter Housing connection and that it is tight and has the Filter Housing O-Ring in place; Check Drain Plug Cap is in place and tight.

WHEN TEMPERATURE SET POINT IS INCREASED, CHILLER DOES NOT STOP RUNNING:

If changing from a low set point to a higher one, or vice versa, the Chiller will switch from Cooling mode to Heating mode to reach the new set point.
The Chiller will also cool or heat to a temperature just beyond the set point to ensure that the Chiller does not cycle on and off excessively and will restart automatically when the water temperature gets outside of the set range by a few degrees Fahrenheit.

WATER HAS BECOME CLOUDY

Check filter element and replace if discolored; Add 60cc (2oz) of Oxidizer to water to break down organics and allow to run for 2 hours; Replace water if this fails.

TUB IS DIFFICULT TO GET INTO BAG

It is important that the Tub be fully deflated before folding. This is done by deflating with the Double Action Hand Pump with an Inflation Hose on the Deflate” side. Ensure the Tub is folded correctly per Takedown instructions.

CAN NOT CONNECT CHILLER TO WIFI

Ensure that the WiFi network you are trying to access is 2.4 GHz. This product only works with a 2.4 GHz wireless network. Some networks can be configured to provide both frequencies if they are dual-band; Ensure the WiFi password is correct by testing with another device; Ensure Chiller is in-range of WiFi signal; Ensure the device with Tuya Smart app has an internet connection.
