Setup
Preparation and Placement Environment
• After receiving the machine, check the packaging to ensure it is in good condition. If there is any
damage, contact our customer service team.
• Remove all packaging materials such as wood boards, protective lm, foam, and cable ties before
using the machine.
• Place the machine in a dry, well-ventilated area, away from heat sources, rain, low temperatures,
and water splashes. Ensure it is on a solid, stable surface, at least 7.87 inches (20 cm) away from
the wall.
• After placing the machine, let it stand for more than 30 minutes before turning on the power to en-
sure normal operation. If cooling is needed, allow the machine to stand for 4-5 hours before turn-
ing on to avoid damaging the compressor. The machine operates at a normal temperature of 60W,
with a cooling capacity of up to 510W, and a heating capacity of up to 760W. Cooling and heating
are optional features.
Parts Functions

tile; otherwise, it may not be recognized.

Cash Machine: Receives, recognizes, stores, and matches cash with an optional prell change func-
tion.
Coin Machine: Receives, identies, stores, and prells coins.

Safety
• Ensure the vending machine is carefully unpacked and inspected before use.
• Keep a minimum distance of 8 inches between the machine and the wall for proper ventilation.
• Place the machine away from heat sources to prevent overheating.
• Maintain a clearance of at least 8 inches on all sides (rear, left, and right) of the machine for ade-
quate airow.
• Protect the machine from contact with water to prevent electrical hazards.
• Avoid placing the machine in areas with low temperatures to prevent malfunction.
• The vending machine must be grounded; operating an ungrounded machine is unsafe and may
lead to security risks.
• Use an AC 110V/60Hz/10A power supply. Avoid voltage uctuations exceeding 200-240V, which
may cause machine failure.
• Use a reliable three-hole socket with grounding. The plug should be easily accessible to prevent
the danger of electric shock.
• Do not damage the power cord. Unplug by holding the plug tightly, not by pulling the cord. Avoid
pressing, stepping on, or crushing the power cord. Replace damaged cords or plugs with the help
of a professional.
• Unplug the power cord before cleaning, repairing, or replacing machine parts to prevent electric
shock.
• Do not dismantle or modify the machine privately; maintenance should be performed by profes-
sionals.
• To retrieve items, push the door of the pickup slot with one hand and reach into the slot with the
other hand to retrieve the goods. The pickup door may be heavy, so handle it carefully and super-
vise children.
• Ensure the machine is properly grounded to prevent electric shock hazards.

Adjustments
Merge the Cargo Lanes:
Disconnect the Tray:
• Cut the tie-up cable.
• Pull out the tray and disconnect the
terminal behind it.
Remove the Bae:
• Unscrew the spring on the right side of the cargo lane to be merged.
• Disassemble the middle bae screw (the plastic bae can be pushed directly inward
and removed).
• Ensure the bae xed by rivets does not support the merged cargo lane.
Replace the Spring and Price Tag:
• Disassemble the right spring and replace it with the left-handed spring.
• Remove the price tag of the right cargo lane and use the price tag of the left lane (e.g., after merg-
ing lane 141 and lane 142, the merged lane is 141).
Reconnect the Motor Wire:
• Pull out the plug of the motor wire on the right side of the cargo lane and insert it into another
jack.
• Connect the merged tray to the terminal.
• Arrange and bind the wiring harness and push it into the main cabinet.
• In the software menu, set the corresponding lane into the merged lane.
Adjustment of Layer Height
Disconnect the Tray:
• Cut the tie-up cable.
• Pull out the tray and disconnect the terminal behind it.
Adjust the Slide Rail:
• Use a screwdriver to loosen and remove the screws of the cargo lane slide rail.
• Adjust the slide rail to the appropriate height and x it with screws (ensure the height of the slide
rail on both sides is the same).
• Reconnect the Tray:

55
Connect the tray terminals.
• Tie up and bind the lane wiring harness.
• Push the lane into the main cabinet.
Installation of Blocking Device
Installation of the blocking device is to prevent taller products from falling forward,
and the upper end of item leaning against the glass, which causes the spring to
be unable to push the product out of the lane.
Installation of spring front end
The front end of the spring is used for some cargo lanes with
thinner products when
the goods can not be pushed out at one time.
