RAPT Can & Bottle Filler | Unit Upgrades
We are constantly innovating to improve your experience. To find the specific upgrade you’re looking for, simply scroll down or use the quick-jump menu on the right. →
Adding the Instant Read Water Resistant Probe allows you to monitor real-time temperatures as you fill. Since temperature is the most critical factor in COâ‚‚ stability, this upgrade helps you make immediate adjustments if your liquid warms up and causes foaming.
The main housing is held together by six Phillips head screws.
Remove all six screws and carefully separate the two halves of the housing.
Tip: Be mindful of any internal wiring that may be connected between the two halves as you pull them apart.
To gain full access to the control boards, the liquid line must be moved out of the way.
Manually press down on the Pinch Valve to open the "jaw."
Pull the silicone liquid line out of the valve and move it to the side.
The RAPT housing features a dedicated port for the temperature probe, protected by a small cap and grommet.
Remove Cap: Locate the small port on the housing. Remove the plastic cap, but leave the rubber grommet in place. (Note: A spare grommet and cap are included in the KL38171 kit if needed).
Insertion: Carefully push the probe end through the grommet from the inside of the housing out. Note: The plug on the cable is too large to fit through the grommet, so the probe must be pushed from the inside out.
Locate the temperature sensor port on the main control board (there is only one compatible socket for this plug).
Plug the lead in firmly until it is fully seated.
Once the lead is plugged in and the cable is seated neatly in the grommet, close the housing halves.
Reinstall the six Phillips head screws and the stainless stand in reverse order.
For the most accurate "real-time" reading, the probe should be positioned directly against the fill lines.
Positioning: Place the probe tip between the Liquid and Purge lines.
Secure: Use the included small rubber band to fasten the probe securely to the lines.
To ensure the device recognizes the new sensor and displays the temperature on the main screen, you must be running the version realeased after 30/04/2025.

Carefully cut the silicone (liquid) and vinyl (gas) tubes at the point where they meet the top of your current stainless fill tubes.
Note: Ensure you make a clean, square cut to provide a better seal on the new tubes.
Follow the same initial steps as the Instant Read Temperature Probe Upgrade to access the internal boards:
Remove Stand: Undo the two wing bolts and two fixed bolts from the sides.
Open Housing: Remove the six Phillips head screws holding the housing together.
The new tubes have different diameters and require slightly different techniques for a secure fit:
Gas Line (Vinyl): The gas line is intentionally tight to prevent leaks. Submerge the end of the vinyl tube in a mug of hot water for 20 seconds. This will make the material pliable and much easier to slide over the new stainless barb.
Liquid Line (Silicone): This tube is softer and slides on easily. To ensure it doesn't slip during a pressurized fill, we recommend securing it with a small hose clamp ( are ideal for this application).
Clear the Valve: Manually open the Pinch Valve and move the silicone liquid line to the side to reveal the control board.
For the best signal strength and a neat finish, the antenna should be mounted to the interior of the housing as specified in the kit.
Carefully peel the backing tape from the antenna to expose the adhesive strip.
Fasten the antenna to the designated spot on the housing (ensure the surface is clean and dry for maximum adhesion).
Standard: RAPT Can & Bottle Fillers purchased after 31/08/2025 do not require this upgrade; the slimline tubes are installed as standard. Units purchased before 31/08/2025 can be easily retrofitted with the KB22681 Slimline Fill Tube Kit by following the instructions below.
Compatibility Check: RAPT Can & Bottle Fillers purchased after 31/01/2025 do not require this upgrade; the antenna is installed as standard. Units purchased before 31/01/2025 can be easily retrofitted with the KL44493 Wi-Fi Antenna Upgrade by following the instructions below.
