• For the goods are not mentioned here, please test before you sell to get the best placement.

• The products should lean backward.

• The single slot, left rotate spiral end should point at 3 o’clock, and right rotate spiral end at 3 o’clock position.

• For merged slots, the spirals should be facing down at 6 o’clock.

Hold the end of the spiral and

pull out the spiral vertically.

(Can feel the elasticity at the

backside.)

Rotate the spiral to the desired

position. Release the spiral.

position and pull-out position.

Guide: How to rotate the spiral to change the position.

Practices that should be avoided when loading spiral slot:

• The top of the goods should not touch the upper tray.

• 8LIKSSHƅW[MHXLWLSYPHRSXI\GIIHXLI[MHXLSJXLIWTMVEPWPSX

• The goods should not be too small to be held by the spiral.

• The product is too thick for the spiral spacing.

• The product should not reach out of the tray. It will effect elevator movement.

• After push back the tray, the spiral may rebounce upward, causing the bottle to slip out.

Push the tray drawer back to the bottom until you hear a thump. Before closing the door, please lightly pull out the tray to

Thin product may fall backward on the beltslot.

If a product leans against it’s front one. They may drop together.

The longitudinal length of the food should < 6 inches. Otherwise may activate the light sensor before the good is fully

moved out.

Temperature Mode: Set the temperature unit to either °C or °F.

Full Screen Mode: When enabled, the navigation bar at the bottom of the screen will be hidden. This

feature is only available when the UI type is set to “0~default” in the “Android System Setting -> Quick

Setup Guide -> UI Type” section.

Paging Display: When enabled, the shopping product lists will be displayed in pages.

Display by Code: If multiple slots sell the same product, you can activate this mode. This will result in

a single product selection tab for that product being displayed on the shopping interface.

ration of product codes is explained in section 1.3, “Maintain Slot Product Info.”

Selling Modes: When this mode is enabled, you must select one of the following selling modes:

Vending First-In-First-Out Mode:

• Products are dispensed according to the slot number sequence. For example, if there are three

slots (1, 2, and 3), the slots will vend one by one. If an error occurs with a slot, the machine will

skip to the next slot.

Always Vend from the First Slot:

Vending First-In-First-Out Mode with Keypad Support:

• For example, if all products in slots 1, 2, and 3 are the same (e.g., Product A), selecting Product A

on the screen will cause the machine to vend by slot number. However, if you enter a slot number

using the keypad, the machine will vend the product from the selected slot.

Slot Management

To accommodate larger products, you can merge slots as needed. Debugging staff can also manage

the status of slots when replacing a driver board or slot.

Slot Management Actions:

Merge Slots:

Choose neighboring slots, then press “Merge” to combine them. Use the “Whole Layer Merging” but-

ton to merge all slots in a tray. (Slots from different trays cannot be merged.)

Split Slots:

Select double-slot or merged slots and split them back into single slots. Use the “Full Layer Splitting”

button to split all slots in a tray.

Add Slots:

Manually add a slot if it is not displayed on the driver board for a newly added tray.

Delete Slots:

Remove unnecessary or non-existing slots.

Transform to Spring Slot:

Select the slot(s), then press the button “Set as Spring Freight Lane” to change the slot type.

Transform to Belt Slot:

Select the slot(s), then press the button “Set as Belt Freight Lane” to change the slot type.

Note: Remember to click “Save” to preserve the settings, and restart the machine to activate them.

Temperature Threshold:

Set the temperature above which the machine will be locked.

Temperature Time Select:

Specify the period of time within which, if the temperature fails to drop to the set level, the machine

will be locked.

Lock Mode:

0 – Lock Mode: When an abnormality occurs, the entire machine will be locked, preventing any prod-

uct sales.

1 – Cargo Mode: When an abnormality occurs, only the faulty slot will be locked, preventing sales

from that slot, while the rest of the machine remains operational.

Note: Ensure that the refrigerating mode is activated before enabling this feature.

Coin:

Unfold this section to see all parameters, including:

Support Coin (Bill) Denomination: In some cases, when a coin changer is equipped, clicking the empty

area between the parameter and the “>” button will reveal additional parameters allowing the user to

set the allowed denominations.

Open Change: This must be enabled when a coin changer is equipped in the machine.

Paper Money:

Unfold this section to see all parameters, including:

Support Bill Denomination: This functions similarly to “Support Coin Denomination” as mentioned

above.

Support Denomination of Refund: This also functions similarly to “Support Coin Denomination.” The

parameter becomes available when the bill acceptor can provide change.

One-Click Empty Banknote Change Box: Works in conjunction with “Support Denomination of Refund.”

Single Maximum Cumulative Coin Amount Switch:

This setting controls the maximum cash amount that a user can insert in a single purchase. When

enabled, an additional parameter, “Maximum Credit $,” will appear, allowing you to set the value (de-

fault is $20). This feature helps prevent customers from using large denomination bills (e.g., $100) to

purchase low-value items (e.g., $1) and receiving a large amount of change.

Manual Change:

When enabled, the user must press the “Change” button on the machine to receive change.

No Vend (Consumption), No Refund:

When enabled, users must use the bills or coins they have inserted to make a purchase. They cannot

receive their money back without making a purchase.

Bill Escrow (Temporary Banknotes):

When enabled, if a customer inserts a bill before selecting a product, the machine will temporarily

store the bill, and the inserted amount will be displayed as “Balance” on the shopping page. If the

customer decides not to make a purchase, they can press the “Change” button to retrieve the inserted

bill(s).

Part II

Keep APP Working in Foreground:

Enabling this function ensures that the vending APP remains in the foreground of the Android

system. This prevents the vending APP from being closed by Android’s self-checking or acceleration

mechanisms.

Note: If this function is enabled, the system may automatically switch back to the vending app while

you are working on other apps. You can temporarily disable this feature if needed.

Quick setup guide: Enabling this function grants access to a quick setup page containing multiple

commonly used setup menus for debugging engineer.

Use Printer:

This is a reserved feature for vending machines equipped with a printer.

Choose Payment Methods First, Then Pay:

After activation, consumers must select a payment method before proceeding with the payment. If

not activated, payment can be made directly without selecting a method. (Note: This function is only

applicable to UI 6.)

Switch to Backend When Door Opens:

After activation, whenever the door is opened, the screen will automatically switch to the Android

backend login interface.

the machine, as they may cause the panel to crack.

Chemical Solvents Warning:

Avoid using chemical solvents like paint thinners or banana water to remove dirt from the vending

machine to prevent accidents.

Evaporator and Condenser Maintenance:

Clean the evaporator and condenser with water on a monthly basis. If necessary, rinse with water.

(Refer to the "Refrigerator Cleaning Guide" sticker on the machine for detailed instructions.)
