# Initial Setup

## Check & Update Firmware

Latest version: **20250430\_155724\_ed6e01f** 

### Check Firmware Version

1. Navigate to: `Menu` > `Diagnostics`.
2. The Firmware Version is displayed on the top row of the screen.
3. Check the Date Code (the first 8 digits of the version name).
   * This indicates the release date in YYYYMMDD format.
   * *Example: `20250430` means the firmware was released on April 30, 2025.*

### Update Firmware

1. Navigate to: `Menu` > `Settings` > `Check for Updates`.
2. The unit will display one of the following messages:
   * **Downloading firmware update:** Stay on this screen until the process completes.
   * **Current firmware up to date:** No further action is required.
3. **Connection Tip:** Ensure you have a strong Wi-Fi signal. If the update fails or hangs, relocate the unit closer to your router and try again.

## Installation & Mounting

The RAPT Can and Bottle Filler is designed for convenient wall mounting. To ensure accuracy, download and print our specialised template:

* [Can & Bottle Filler Wall Mounting Template](https://www.kegland.com.au/cdn/shop/files/RAPT_Can_and_Bottle_Filler_Wall_Mounting_Template.pdf)
* **Note:** When printing, ensure your printer settings are set to "Actual Size" (100%) on standard A4 paper. Do not "Fit to Page," or the drill holes will be misaligned.

#### Recommended Hangers

These [Stainless Steel Adhesive Wall Mounting Hangers](https://kegland.com.au/products/stainless-steel-adhesive-wall-mounting-hangers-4-pieces-7cm-x-7cm) (KL50715) allow for hanging without having to drill into a wall. They are ideal for hanging the unit to a fermentation chamber or canning machine.

## Optimising: Liquid Post Setup

The RAPT Can and Bottle Filler is designed to minimise foam during carbonated fills. Depending on the version of the Liquid Post (Yellow) your unit shipped with, you may or may not need to modify the internal poppet.

#### **Check your Liquid Post Version:**

<figure><img src="/files/89DhBRjTYUl9GmoRwwG3" alt=""><figcaption></figcaption></figure>

* **New (No Modification Required):** If your liquid post features a poppet with a black plastic over-moulded piece, do not remove it. This newer design is optimised for low-turbulence flow and functions perfectly as a standard "dry-break" connection.
* **Original (Modification Recommended):** If your liquid post has a standard all-metal or older-style poppet, we recommend removing the internal poppets from both the Liquid Post (Yellow) and the Liquid Ball Lock Disconnect.

> <img src="/files/2lAcdgaOsVS7zlrU7dIC" alt="" data-size="line"> Important: Once poppets are removed, these fittings are no longer "dry-break" connections. You must disconnect the liquid line at the keg before disconnecting the RAPT filler to prevent beverage spray.

## Power Supply & Pressure Limits

* **Power:** Requires a 24V DC power supply (minimum 1 Amp).
* **Beverage Pressure:** DO NOT exceed 15 psi (1 bar). High pressure will cause foaming and may lead to liquid hose failure.
* **Gas Pressure:** Any pressure above 2 psi is acceptable. The unit features an integrated regulator to handle higher input pressures.

## Adjusting the Integrated Gas Regulator

You only need to perform this calibration once during your initial setup.

1. **Initial State:** Use a screwdriver to turn the regulator adjustment screw fully anti-clockwise (all the way out).
2. **Test Environment:** Place a large glass full of water into the fill position.
3. **Test:** Navigate to `Menu` > `Manual Fill`. Hold the **Up** <img src="https://docs.rapt.io/~gitbook/image?url=https%3A%2F%2F570278281-files.gitbook.io%2F%7E%2Ffiles%2Fv0%2Fb%2Fgitbook-x-prod.appspot.com%2Fo%2Fspaces%252FUqN4sW0x2s4yh6iiT8NN%252Fuploads%252Fwlc1Puwef1yzNmEJ9Els%252FUP%2520RAPT.png%3Falt%3Dmedia%26token%3D04bacbbf-b73d-4b89-96f2-fd2e88ee5b92&#x26;width=40&#x26;dpr=4&#x26;quality=100&#x26;sign=9c897ea&#x26;sv=1" alt="" data-size="line"> and <img src="https://docs.rapt.io/~gitbook/image?url=https%3A%2F%2F570278281-files.gitbook.io%2F%7E%2Ffiles%2Fv0%2Fb%2Fgitbook-x-prod.appspot.com%2Fo%2Fspaces%252FUqN4sW0x2s4yh6iiT8NN%252Fuploads%252Fxl1gN3QzdWP0KGqcqA1c%252FDOWN%2520RAPT.png%3Falt%3Dmedia%26token%3Dece187d3-c67e-43d5-969f-dbbd026b9341&#x26;width=40&#x26;dpr=4&#x26;quality=100&#x26;sign=99de4b92&#x26;sv=1" alt="" data-size="line"> **Down** simultaneously. Gradually turn the screw clockwise until you see bubbles emerging from the gas tube.
4. **Set Flow:** You only need a light, steady flow. Once you see consistent bubbling, the setting is perfect.
   * *Note: If gas flows continuously and won't stop after the purge cycle, your pressure is too high. Turn the screw anti-clockwise to rectify.*
