INSTALLATION SITE
This unit must be installed in a location which meets all the conditions described below.
• If the unit is installed in a location which does not meet the conditions, its specified performance may not
be achieved or malfunctions and accidents may occur.
■
A location not exposed to direct sunlight
Avoid any location which is exposed to direct sunlight. Installing the unit in a location exposed to direct
sunlight may reduce its cooling performance.
■ A well-ventilated (airy) location
In order to ensure ventilation, leave clearances of at least 10 cm around the unit (at the left, right, top and
back). Blocking the ventilation may reduce the unit’s cooling performance or cause malfunctions.
■ A location away from sources of heat
Avoid any location which is close to a major source of heat (such as a heater or boiler). Installing the unit
near a major source of heat may reduce the unit’s cooling performance.
■ A location with minimal changes in temperature
Avoid any location where the ambient temperature is subject to sudden changes. If the unit is installed in
a location where the ambient temperature is subject to sudden changes, it will not be possible to achieve a
stable cooling performance. The ambient temperature to use is +5
o
C degrees to +35
o
C degrees for
MDF-MU339, +5
o
C degrees to +30
o
C degrees for MDF-MU539.
■ A flat surface where the floor is also capable of bearing the total combined weight (product +
optional acces stored items)
Install the unit on a flat surface which is even and which is capable of bearing the total combined weight
(product + optional accessories + stored items). If the unit is installed where the surface is uneven or
where the unit will be inclined at an angle, the unit will be unstable, and accidents or injuries may occur
and/or unnecessary vibration or noise may be generated.
■ A location with minimal humidity
Install the unit in a location where the relative humidity is less than 80 %R.H. Installing the unit in a very
humid location may cause earth faults and/or electric shock.
■ A location free of flammable or corrosive gases
Avoid any location exposed to flammable or corrosive gases. Flammable or corrosive gases can cause
explosions and/or a fire. Furthermore, corrosion of the electrical parts may cause the insulation to be
reduced and result in earth faults and/or electric shock.
■
A location where nothing can fall onto the unit
Avoid locations where objects may fall onto the unit. Objects falling and hitting the unit may cause it to
break down or fail.
