INTRODUCTION

This CO2 Refrigeration system is for the V21 Vending Machine.

INPORTANT & WARNING

Ozone Hole

Infrared lays

Grobal warming gas

Not destroy Ozone layer		Low potential of Grobal
		warming

10MPa

Very High Pressure

The refrigeration unit contains R744 (carbon dioxide). Only technical person who has been trained the operation of R744 (carbon dioxide) is able to fix the cassette.

Do not eject the refrigerant by person who hasn’t been trained about R744 because the pressure is very high. Please check the characteristics in the following table.

Refrigerant	R744	R134a
Ozone destructive potential
Green house warming potential		1300
Permission concentration	5,000ppm	1,000ppm
Operating pressure	10MPa	2MPa

CAUSION: Do not breathe under high density condition of CO2. It will cause below symptom

~4 %: headache, dizzy, Flushing face 4~6%: frequent breathing, vomit

6~8%: difficulty breathing, congestion of lung 10%~: unconscious, stop breathing

Power input. Use the cabinet at specified voltage.(Make sure the voltage corresponds to that mark on Name plate which is located on the front right corner of the base plate. Maximum variation is +/-10%)

Use only standard socket. Multi socket is not acceptable and do not plug other electrical units into the same wall outlet of the cooler plugged into. Do not use extension cord. The contact of socket must have minimum distance 3mm and suitable to cut off the power incase of emergency.

The V21 machine must be grounded for safety. Make sure the plug has a terminal for grounding, which complies with the local regulation. (Adapter is acceptable if necessary)

Do not use mechanical devise or other means to accelerate the defrosting process without manufacture recommendation.

If supply cord is damaged, it must be replaced.

****Installation should be carried out according to Manufacture’s instruction by qualify person and infirmity with the Local regulation.

****The manufacture accepted no liability for damages to people or objects that cause from wrong installation or some modification of equipments.

A COMMITMENT TO SAFETY

SandenVendo America is committed to safety in every aspect of our product design. SandenVendo America is committed to alerting every user to the possible dangers involved in improper handling or maintenance of our equipment. The servicing of any electrical or mechanical device involves potential hazards, both to those servicing the equipment and to users of the equipment. These hazards can arise because of improper maintenance techniques. The purpose of this manual is to alert everyone servicing SandenVendo America equipment of potentially hazardous areas, and to provide basic safety guidelines for proper maintenance.

This manual contains various warnings that should be carefully read to minimize the risk of personal injury to service personnel. This manual also contains service information to insure that proper methods are followed to avoid damaging the vendor or making it unsafe. It is also important to understand these warnings are not exhaustive. SandenVendo America could not possibly know, evaluate, or advise of all of the conceivable ways in which service might be done. Nor can SandenVendo America predict all of the possible hazardous results. The safety precautions outlined in this manual provide the basis for an effective safety program. Use these precautions, along with the service manual, when installing or servicing the vendor.

We strongly recommend a similar commitment to safety by every servicing organization. Only properly-trained personnel should have access to the i nterior of the machine. This will minimize the potential hazards that are inherent in electrical and mechanical devices. SandenVendo America has no control over the machine once it leaves the premises. It is the owner or lessor’s responsibility to maintain the vendor in a safe condition. See Section I of this manual for proper installation procedures and refer to the appropriate service manual for recommended maintenance procedures. If you have any questions, please contact the Technical Services Department of the SandenVendo America office nearest you.

SAFETY RULES

•Read the Safety Manual before installation or service.

•Test for proper grounding before installing to reduce the risk of electrical shock and fire.

•Disconnect power cord from wall outlet before servicing or clearing product jams. The vending mechanism can trap and pinch hands.

•Use only fully-trained service technicians for PowerOn servicing.

•Remove any product prior to moving a vendor.

•Use adequate equipment when moving a vendor.

• Always wear e ye protection, and protect your ha nds, face, and body when working near the refrigeration system.

•Use only authorized replacement parts.

•Be aware of inherent dangers in rocking or tipping a vending machine.

SECTION I: VENDOR INSTALLATION

A.Vendors are large, bulky machines of significant size and weight. Improper handling can result in injury. When moving a vendor, carefully plan the route to be taken and the people and equipment required to accomplish the task safely.

B.Remove all tape, shipping sealant, and Styrofoam from the vendor. Loosen any shipping devices used to secure interior parts during shipping. Remove the wooden shipping base attached to the vendor base by the vendor leveling screws. Make certain the leveling screws are in place and functional.

C.Position the vendor three to four inches (7.6 cm to 10.2 cm) from a well-constructed wall (of a building or otherwise) on a flat, smooth surface.

IMPORTANT: The vendor requires three inches (7.6 cm) of air space from the wall to ensure proper air circulation to cool the refrigeration unit.

D.Adjust the leveling screws to compensate for any irregularities on the floor surface. Ideally, no adjustment will be necessary and the leveling legs will be flush with the bottom of the vendor. A spirit level is a useful aid to level the vendor. When the vendor is properly leveled the outer door, when opened, will remain stationary. Vendors must be level to ensure proper operation and to maintain stability characteristics. Do not add legs to the vendor. The leveling legs shall not raise the vendor more than 1 1/8 inch above the ground.

E.Check the manufacturer’s nameplate on the left or right side of the vendor’s outer door to verify the main power supply requirements of the vendor. Be sure the main power supply matches the requirements of the vendor. To ensure safe operation, plug the vendor only into a properly grounded outlet.

DO NOT USE EXTENSION CORDS.

F.Recommended voltage specs = 115V ± 10%

G.Dedicated 15A service required for 1 machine.

NOTE: Any power supply variance more than + 10% may cause the vendor to malfunction.

*Power outlets must be properly grounded.

*Power outlets must be properly polarized, where applicable.

Test the outlets using the following information.
