INSTALLATION
When installing the unit, follow the steps below to secure the unit properly, and also be absolutely sure to
connect the unit to ground.
In addition, install a ground fault circuit breaker (on the unit’s power supply side) which is mandatory under the
applicable laws and regulations.
1.
Preparations after unpacking
Remove all the tapes used to secure the doors and interior parts, and leave the doors open for a short
while for ventilation.
If any surfaces of the outer cabinet are dirty, wipe off the dirt using a cloth moistened with a diluted
neutral dish-washing detergent.
Using an undiluted solution of a neutral dish-washing detergent may cause the unit’s plastic areas to crack.
Follow the directions of the neutral dish-washing detergent for the dilution details.
After removing the dirt using the diluted neutral dish-washing detergent, be absolutely sure to wipe the surfaces
with a cloth dipped in clean water to remove the traces of the neutral dish-washing detergent. After this, be
absolutely sure to wipe the surfaces with a dry cloth, allow the surfaces of the outer cabinet to dry out, and then
proceed with the installation.
2.
Securing and leveling the unit using the leveling feet
Rotate the front leveling feet clockwise until the casters are
raised 5 mm to 10 mm from the surface of the floor. (Fig. 1)
When the casters are raised from the surface of the floor, the
unit is secured. If they are left touching the floor, the unit may
inadvertently move out of position when its doors are opened or
closed.
In addition, rotate the leveling feet slightly clockwise or
counterclockwise, and adjust them so that the unit is level
between the left and right.
3.
Securing the unit using the wall-fastening brackets
Use the spacers (which are also used to prevent the
product from toppling over) on the rear panel of the unit,
and secure the unit to a wall with a strong rope or chain
available on the market. (Fig. 2)
The spacers (which are also used to prevent the product from
toppling over) have a dual purpose: To provide a clearance
between the product and the wall behind it, and to prevent the
product from toppling over.
4.
Preventing electric shock by connecting the unit to ground
When installing the unit, be absolutely sure to connect it to ground. Grounding is necessary to prevent
the electric shock which will arise when the electrical insulation has deteriorated.
This unit comes with a 3-pole plug with ground pin.
Grounding work is not required in the case of a 3-pole power
outlet equipped with a ground contact.
If the power outlet is not a 3-pole power outlet equipped with a ground contact, ask a qualified contractor to do the
grounding work.
WARNING
Be absolutely sure to connect the unit to ground in order to prevent
electric shock. If the unit cannot be connected to ground, ask a qualified
contractor to do the grounding work.
Failure to connect the unit to ground may give rise to electric shock.
Do not connect the grounding wire to a gas pipe, water pipe,
lightning rod or telephone grounding wire in carrying out the
grounding work.
Connecting the unit to ground improperly may give rise to electric shock.
