piping.)
During operation : -5 to 45°C
When the ambient temperature or circulating fluid temperature is 10oC or below,
use the circulating fluid specified in "3.2.2 Operation at low ambient temperature
or low circulating fluid temperature".
●Location where condensation forms on the inside electrical parts.
●Location that is exposed to direct sunlight or heat radiation.
●Location that is near heat sources and poor in ventilation.
●Location that is subjected to abrupt changes in temperature.
●Location that is subjected to strong electromagnetic noise (intense electric field,
intense magnetic field, or surges).
●Location that is subjected to static electricity, or conditions where static electricity can
discharge to the product.
●Location that is subjected to strong high frequencies raditation.
●Location that is subjected to potential lightening srtike.
●Location at altitude of 3000m or higher (except during product storage and transport).
Refer to below for details.
●Location where the product is affected by strong vibrations or impacts.
●Condition that applies external force or weight causing the product to be damaged.
Do not set up the product in exposed locations where there is a risk
offlammable gas. Should any flammable gas remain around the
product, the product may cause a fire.
Keep the product upright on a rigid and flat floor which can resist the
weight of the product. Take measures to prevent the product from
tipping over. Improper installation may cause water leakage, tipping,
damage of the product or injure the operator.
Keep the ambient temperature of the product between -5 to 45oC.
Operation out of this ambient temperature range may cause a
product malfunction. Operating the product in an environment
temperature of 45 oC may reduce the heat discharging efficiency of
the heat exchanger and the safety device may function, resulting in
the stoppage of the product operation.
Following the installation, The installer/end user is responsible for
performing an acoustic noise risk assessment on the equipment and
taking appropriate measures as required.
