Precautions for installation

WARNING

Installation should be performed only by the dealer or a qualified expert. Attempting to install the unit yourself could result in water leakage, refrigerant leakage, electrical shock or fire.

Precautions for use

WARNING
All repairs, disassembly and modifications should be performed only by qualified technicians. Attempting to perform these yourself could result in a fire, malfunction and injury.

Never put flammable or volatile substances into the unit as explosion and fire could result.

Never splash water directly onto the product or wash with water as shortcircuit and electrical leakage could result.

Do not damage, modify, excessively bend, strain, twist or bundle up the power cord. Also, placing heavy objects on the power cord or squeezing it into a tight place could damage it, possibly resulting in electrical shock or fire.

Use a dedicated wall outlet. Do not use extension cords or convenience receptacles as this could result in overheating, which could lead to fires or an electrical shock.

The cooler is intended for storage and display of beer and beverages for sale. Donot use for other purpose than the intended as this could adversely affect items placed in the unit.

For indoor use only. Using the unit in a location exposed to rain could result in electrical leakage and electrical shock.

Install the unit in a location where the floor is sturdy enough to support the load of the unit. If the floor is not sturdy enough or installation is incorrectly performed, the unit could tip over and  falling shelves and products could cause personal injury.

Store the unit in a location where it is noexposed to rain. Using a unit that has been exposed to rain could result in electrical leakage and electrical shock.

Never use flammable spray cans or leave flammable substances near the unit.
Sparks from electrical switches could result in explosion and fire.

Never attempt to insert fingers, sticks, etc. into the cold air suction outlet.
A circulation fan is rotating at high speed inside the outlet. Injury, electrical shock and improper operation could result.

Never place heavy objects or items containing water on top of the unit.
Objects could fall down and cause injury and spilled water could deteriorate the insulation of electrical components and result in electrical leakage.

If you find gas leakage, please don’t touch the cooler. Close all gas valves and open the door(s) for ventilation. Gas leakage could cause explosion or start a fire which can cause a fire injury.

Place the unit away from hot air sources. The cooling performance will be reduced if the unit is placed near heat sources such as hot plates and stoves and if it is exposed to direct sunlight.

Leave disassembly and disposal of the unit to qualified experts.

WELL VENTILATED PLACE Please leave more than 10cm space between unit and the wall. If there is no space, the cooling capacity will be reduced.

Never hang from the door or climb onto the unit. The unit could tip over or fall and cause material damage or injury.

Grasp the handle when closing the door. Holding at other positions could result in pinched fingers and injury.

When disconnecting the power cord plug from the wall outlet, hold at the plug main body close to the outlet. Pulling the cord could cause wire breakage, possible resulting in overheating and fire.

Do not throw items onto the shelves and do not place items totalling more than 30kg on each shelf. The shelf could fall down, possibly causing injury or break the shelf itself.

Should the unit need temporary storage, make sure not to store the unit in a location where children play and take precautions so that the door(s) cannot be completely closed. This will minimize the risk that a child becomes trapped inside the compartment.
If installation in a damp location is unavoidable, please install an electrical leakage circuit breaker. If no electrical leakage circuit breaker is installed, electrical shock could result.

Disconnect the power cord plug from the wall outlet before moving the unit and make sure that the power cord is not damaged during transport. A damaged power cord could result in electrical shock and/or fire.

Do not apply excessive force to the glass surfaces as the glass could break/smash and cause personal injury.

Make sure that the unit does not tip over or fall when it is moved. A falling unit could cause serious injury.

Be sure to attach and secure shelves correctly. An improperly attached shelf could fall down and cause injury or break the shelf.

HOW TO USE

Before use

• Remove shipping package, tape, etc. Also leave the door(s) open for ventilation for a while.
• The unit is cleaned before shipment. However, clean the compartment interior once after delivery.
• Please insert power supply plug into the wall outlet, single-phase to cat voltage.
• Allow the unit to operate for about 1 hour to cool the compartment before placing items in the cooler.

WAIT 5 MINUTES OR MORE BEFORE RE-STARTING

• Restarting the unit immediately after it has been turned off may cause fuses to blow and activate the circuitbreaker, thus, the compressor may be overloaded and/or other damage may occur.

Temperature adjustment

See the “digital controller manual” on page 30.

Drain tray

• Defrosting is performed automatically and drain water is collected in the drain tray.
• Water in the drain tray is evaporates automatically. In humid surroundings, there will be large amounts of water in the drain tray, so please throw away drain water at least once a day.

Efficient use
Please follow the instructions below, to save energy.

• To prevent cold air from escaping, open and close the door(s) quickly and keep the door(s) opened for as short a time as possible.
• Please install the unit in the place which is well-ventilated.

Shelf height adjustment
The shelf height can be adjusted. Arrange the shelves in accordance with the dimensions of the items to be placed in the cooler.

Placing items in the showcase
This showcase employs a forced circulation of cold air system. If circulation of cold air is obstructed, the items will not be adequately refrigerated. Pay attention to the following points:

• Do not let items obstruct the cold air inlet and suction outlet.
• Place items so that they do not protrude from the shelves. The gap between the shelves and the door(s) is used for circulation of cold air.
• Place items evenly on all shelves.
• Please do not display goods on the bottom. Please put goods on the shelf.

CLEANING

WARNING
To prevent any electrical shock hazards or injury by rotating circulation fan, always disconnect the power cord plug from the wall outlet before cleaning.
Exterior and cooler compartment
Wipe the exterior and cooler compartment of the unit with a soft, dry cloth. If very soiled, wipe with a cloth that has been moistened with a detergent. Then wipe with a cloth that has been dipped in water.
WARNING
Do not splash water directly onto the cooler and do not wash with water.
Short-circuiting and electrical shock could result.

• Clean the cooler regularly to keep it clean at all times.
• Never use polishing powder, soap powder, gasoline, oil or hot water as these will damage the painting and plastic components.

Checks after cleaning
To ensure the safety, perform the following checks after cleaning the unit.

• Make sure that the power plug is firmly inserted into a dedicated wall outlet. Confirm that the plug is not abnormally hot.
• Check the power cord for cracks and damage. Should the slightest irregularity be observed, contact the dealer form whom you have purchased the unit.
