2.2 Precautions Concerning Installation
Location
This section describes the precautions to be taken when installing the unit. Make
sure to observe them.
■
Do not use the unit in a fl ammable atmosphere.
To prevent the possibility of explosion or fi re, do not use the unit near alcohol, thin-
ner or other combustible materials, or in an atmosphere containing such vapors.
■
Avoid locations where the unit is exposed to high temperature
or direct sunlight.
Do not place the unit near a heater or in areas subject to drastic temperature
changes.
Operating temperature range: 0 ° C to +40 ° C (+32 ° F to +104 ° F)
Storage temperature range: -25 ° C to +70 ° C ( -13 ° F to +158 ° F)
■
Avoid humid environments.
Do not place the unit in high-humidity locations--near a boiler, humidi fi er, or water
supply.
Operating humidity range: 20 % to 85 % RH (no condensation)
Storage humidity range:
0 to 90 % RH (no condensation)
Condensation may occur even within the operating humidity range. In such case, do
not use the unit until the condensation dries up completely.
■
Do not place the unit in a corrosive atmosphere.
Do not install the unit in a corrosive atmosphere or in environments containing sul-
furic acid mist, etc. This may cause corrosion of various conductors and bad con-
tacts of connectors inside the unit leading to malfunction and failure, or in the worst
case, a
fi re.
However, operation in such environments may be possible through alteration. If you
wish to use the unit in such environments, consult your Kikusui agent or distributor.
■
Do not place the unit in a dusty location.
Accumulation of dust can lead to electric shock or fi re.
■
Do not use the unit where ventilation is poor.
The unit employs a forced air cooling system. Air is taken in from air inlet located
on panels other than the rear panel and exhausted from the air outlet on the rear
panel. Secure adequate space around the unit to prevent the possibility of
fi re caused
by accumulation of heat.
Allow at least 20 cm of space between the air inlet/outlet and the wall (or obstacles).
Hot air (approximately 20
°
C higher than the ambient temperature) is exhausted
from the air outlet. Do not place objects that are affected by heat near the air outlet.
