Refrigerant type: R134A, about 320 g needed for purging and charging.
Installing and starting the machine
When placing the machine on site, leave at least 10 cm of free space from the rear wall for the compressor unit's heat dissipation. It is forbidden to operate the machine without feet/wheels, installed in a niche without normal air circulation behind it.
Connect the power cable to the socket on the rear wall and set the button to "I". Inside the machine, on the bottom shelf, set the power breakers to the upper position. Wait for the PC to load and the trade matrix to appear on the display. To access the machine settings menu, tap the top-right corner of the display 5 times.
Access and role setup
Request the administrator password from Shaker technical support. A separate account with limited access is set up for restocking staff.
Changing the administrator password
In the side panel, select General settings - Roles , enter the new administrator password twice and press "Change". After the app restarts, log in with the new password.
Adding, editing and deleting restocker accounts
In the side panel, select "General settings" - "Roles" and use the icons to add, edit or delete restocker accounts.
Mechanical diagnostics
Cell test
Open Error diagnostics - Cell test . To test any single cell, select it on the matrix and press "Test". To test all cells, press "Select all" and "Test". In this mode the machine checks the cell motors' operation with the optical sensor on — with no products in the cells, each cell will show a dispense error (if the dispense sensor is on). You don't need to worry about this yet — just make sure all cells complete the dispense cycle correctly.
Motor calibration
Cell motor calibration is done if the motor's start and end positions fail.
Open Error diagnostics - Cell test . Select the required cells or all cells and press "Calibration". After the motor finishes, set the cell spring to the correct position. Repeat the cell calibration and spring-position adjustment until the product dispenses normally.
Setting the spring position
For correct dispensing, springs are positioned according to their purpose:
Spring for 10 and 14 products (small/medium snacks) — position 90 degrees left ;
Spring for 5 products (bottles) — position 90 degrees right .
To adjust the position, pull out the shelf, grip the spring's locking wheel, pull it towards you together with the spring, and turn it to the required position. Gently release the wheel.
Open Cell management - Cell configuration . Select one or more cells and use the tools to merge, un-merge, or change the type or size of cells. The shelf configuration changes automatically depending on whether the shelf wiring harness is physically connected. To change cell capacity, go to the Cell management - Depth tab.
Working with "Chestny Znak" (mandatory product labelling)
Working with this product category is done by withdrawing the product from circulation on the grounds of sale via a vending machine. Read more about Chestny Znak here; for setup on the Vendista side, refer to this guide.
Product database
Adding products has 3 stages:
Preparing product images;
Adding new products in the telemetry cabinet;
Uploading the product database file to the machine.
Preparing product images
Find a suitable product photo of 400-700 pixels per side (no smaller; larger is fine);
Crop the photo, leaving a small margin from the edges, and remove the background (you can use a free editor);
Rename each photo according to the product name (e.g. "Still water, apple flavour").
Adding new products in the telemetry cabinet
This stage requires a telemetry cabinet. If you don't have one, send your registration details (full name, phone number, email) to technical support.
After logging in, select the "Products" tab in the side panel. This tab offers a product search bar, adding new products, and exporting the product database to a file.
Press "+Add" to add new products. Fill in the required fields:
"Brand" field — the product's brand name (if missing, you can create a new one);
"Product" field — the product name;
Product barcode (can be arbitrary);
Product photo — for correct display on the machine, rotate the image correctly. Photos of bottles and long products should be rotated to the left . You can rotate the image after uploading; if needed, you can replace the image or flip it in the product edit mode . You can also rotate the product photo on the machine screen after uploading the database — go to the Cell configuration screen of the Cell management tab.
Press "Add" to save the product.
Uploading the product database file to the machine
On the "Products" screen, press "JSON" to export the product database file;
Make sure the file name is "goods" with no extra characters. Copy the file to a flash drive and connect it to the machine PC's USB;
Close the app on the screen. Swipe the bottom panel with the icons up and open the File Manager;
Tap the icon at the top left, open the side panel, find your flash drive and open it. Copy the goods file (press and hold until it is selected, then press "Copy" at the bottom left);
Open the side panel, go to "Home folder" - "Vending files" - "goods". Press "Paste" at the bottom left, then "Overwrite";
Minimise the windows, start the app on the main screen, and enter the admin menu;
On the "General settings" tab, under "Update product list", press JSON, confirm, and wait for the product lists to update. Attention! Updating the product database deletes all previously loaded assortment. Products not in the new database will be removed.
Product images are loaded when the assortment file is updated; internet access is required. If the assortment was updated from a flash drive without internet, you must provide internet to load the images and press Update product photos in the general settings section.
Changing the product in a cell
Open Cell management - Products . To change a cell's product, tap the required cell and enter the product name in the search bar. Press "Apply" to save.
Changing product prices
Open Cell management - Prices . Select the required cell, enter the price and press "Apply".
Temperature, lighting and dispense-sensor settings
To monitor and change temperature modes, open Machine settings - Machine . The screen shows the current refrigeration-chamber temperature and options to change settings. IMPORTANT! The initial cooling configuration may not suit the machine's operating conditions on site. After sales start, regularly check the temperature in the first days and adjust the cooling settings if needed.
To turn the refrigeration chamber lighting on/off, use the LED lighting option.
The optical sensor detects product dispensing from a cell. To enable/disable the dispense optical sensor, use the No drop-sensor mode option (off by default — meaning the sensor is enabled).
Payment device and purchase settings
Payment terminal settings
Connect the cashless payment terminal to the MDB connector on the inside of the machine door. Go to Machine settings - General to edit payment time and timeout settings.
SBP (QR-code) payment must be configured on the cashless terminal side. To enable SBP payment on a Vendista terminal, send the terminal this list of commands . No terminal cable modification is required.
Disabling stock tracking
To disable stock tracking, use the Infinite stock option.
"Everything free" mode
To enable free product dispensing, use the Everything free option. ATTENTION! This option is enabled by default and must be turned off after connecting payment devices. If the mode is turned off before payment devices are connected, the purchase screen will be blocked by an error.
Cell blocking on failed dispense
The option disables a cell when a product was not dispensed (the optical sensor did not detect the product, the product ran out, or there was a dispensing problem). You can set the number of retry attempts before blocking.
Keyless access to the machine (opening the door lock by QR code)
Open the machine settings menu and go to the Machine settings section. In the "Door open code" field, enter any code of numbers and letters and press Apply. Open any online QR-code generator (for example this one) and generate a QR from your code. Save the QR to your device; to open the door, show your QR code to the machine scanner. After a successful read, the lock releases and an opening-lock animation appears on the machine screen.
IMPORTANT! The code from the machine menu stops working when the machine is connected to telemetry. A new lock code can be obtained from the telemetry cabinet after registration.
Advertising module
Upload advertising materials to the machine folder: /storage/emulated/0/VendingFiles/ads. Supported formats:
Images: jpg/jpeg, png, webp, gif;
Video: mp4, mkv, webm.
To set the module's on/display timers, open "Purchase settings" - "Advertising".
IMPORTANT! Do not place the modem inside the housing — this greatly degrades signal quality. Place the device on a USB extension cable, or connect an external antenna outside the housing.
Setting up remote access
Open Android settings and press "Exit to Android" to minimise the app. On the toolbar, open the AnyDesk or MyAssistant program. Request the connection password from Shaker technical support.
Software update
To update the machine software, submit a request to technical support. If a remote update is not possible, request the installation file and copy it to a flash drive. Then:
Connect the flash drive to a free USB port on the tablet.
Exit to the Android menu on the tablet.
Open the File Manager, find your flash drive, and run the copied installation file. Open the app after installation. The installed app version is shown in Error diagnostics - System information .
Under Russian law, the sale of 18+ products (e.g. energy drinks) is only possible with buyer age confirmation. The machine can enable age identification at purchase via the MAX messenger — read more in the Age Verification for Buyers (Shaker Prime) guide.
Errors, problems and solutions
Question: A cell on the purchase screen is greyed out (inactive) and cannot be bought from. Answer: Check the cell's product stock. Run a test dispense and make sure the cell is not blocked due to a failed dispense.
Question: A product cell is not shown on the purchase screen and is not in the settings either. Answer: Check the wiring harness connector to the cell motor. With poor connector contact, the cell is disabled from sale. Reboot the machine and check whether the cell appears. If there is no result after reboot, submit a request to technical support for diagnostics.
Question: Some shelves/cells have disappeared. Checking the shelf and cell connectors and rebooting did not help. Answer: Disconnect and reconnect the cell motor power connector and the shelf harness connector, then refresh the shelf configuration in the Cell configuration section. If this does not help, submit a request to technical support.
Question: The machine dispenses several products from a cell when only one unit is purchased. Answer: The cell motor needs replacing. Submit a request to technical support for diagnostics.
Question: After any purchase an auto-refund occurs. The product is always dispensed with an extra spring turn. Answer: There is a problem with the dispense optical sensor. Turn it off and submit a request to technical support for diagnostics.
Question: A cell is inactive and shows a wrench icon . Answer: The cell was disabled in software after a failed dispense. Open Cell management - Cell configuration, enable it and check the dispense.
Question: Are there height limits for products? Answer: Yes, one-litre bottles are not allowed.
Question: At what height can bottles and cans of drinks be placed? Answer: Plastic bottles can go on any shelf; metal cans no higher than shelf 3.
Question: The door-open code from the settings menu does not work — what should I do? Answer: Check which code is entered in the machine settings and regenerate it. Open General settings - Devices; the QR-code scanner device must be assigned a serial port (WMC COM or CDC), port speed 9600. Press the connection-check button and make sure the device status is green. Go to the Server tab and make sure nothing is selected in the "Telemetry server selection" field.
