throughout the year.
o Install at a place free from moisture and dust.
o Do not install near combustibles, corrosive gases, and high-tem-
perature heat sources.
o Install on a level floor. (Allowable levelness is within 2 mm.)
o Install away from any equipment that may generate noise.
o Secure space around the chamber as illustrated in order to facili-
tate ventilation and maintenance.

*1 Please note that a minimum space of 600 mm is necessary
between the wall and the chamber when maintenance work
needs to be done that requires opening the back panel.

Preparation Before Use
• Connecting to the Power Source
..'. r..
o The power source specification of this chamber is AC200V ± 10%,
3-phase, SO/60Hz.
o As this device is equipped with a microcomputer, be sure that it is
properly grounded.
o Please connect the power switch of the specified capacity between
the primary power source and the chamber's electrical cord.
* For information of power switch capacity, cable and ground wire
diameters, please refer to "Power Connection Specifications" on
page 116.

Precautions for Use
II Precautions for Use
o Place specimens in such a manner that the air circulation in the
test area is not obstructed.
o The chamber is not a clean room, therefore, it is not suitable for
tests which require dust-free test conditions.
o Do not use specimens that emit corrosive gases because such
specimens deteriorate the materials of chamber.
o Do not place any explosive or flammable substances (including
those listed on the next page) inside the chamber.
o Avoid opening the door during temperature/humidity tests as it may
cause the dangers and injuries described below.
(1) High temperature/humid air may blowout and burn your skin.
(2) As the test area is heated, you may burn your skin by touching
metal parts, etc.
(3) The fire alarm may be activated if it is mounted on the ceiling
above the chamber.
o If the chamber is used for low temperature / high humidity tests
continuously for a long period, temperature / humidity control may
become less accurate due to formation of frost around the cooling
coil. Regularly run the chamber at high temperatures to remove
such frost. (See "Error Diagnosis List" on page 103.)
o When the chamber is operated with temperature setting only, hu-
midity is not controlled. For the specimen that requires strict hu-
midity control, please make sure to set the humidity as well.
5

Precautions for Use
o If the maximum ramp-up I ramp-down rate is set, the actual tem-
perature I humidity may overshoot the set value as the maximum
capacity is engaged for such a setting. For the specimen which
requires strict temperature Ihumidity control, please make sure to
set the ramp-up Iramp-down time.
o Do not turn on or off the power switch and other switches abruptly.
It may cause malfunction of the chamber especially when a hu-
midity test is performed .
......t •.
o Explosive Substances
(1) Nitroglycol, nitroglycerine, nitrocellulose, and other explosive
nitrate esters.
(2) Trinitrobenzene, trinitrotoluene, picric acid, and other explosive
nitro compounds.
(3) Peracetic acid, methyl ethyl ketone peroxide, benzoyl perox-
ide, and other organic peroxides.
(4) Sodium azide and other metal azides.
o Flammable Substances
(1) Combustibles
• Metal lithium, metal potassium, metal sodium, yellow white
phosphorus, phosphorus sulfide, red phosphorus, celluloids,
calcium carbide, lime phosphide, magnesium powder, alumi-
num powder, other metal powders, sodium dithionite (or hy-
drosulfite).
(2) Oxides
• Potassium chlorate, sodium chlorate, ammonium chlorate, and
other chlorates.
• Potassium perchlorate, sodium perchlorate, ammonium per-
chlorate, and other perchlorates.
• Potassium peroxide, sodium peroxide, barium peroxide, and
other inorganic peroxides.
• Niter, sodium nitrate, ammonium nitrate, and other nitrates.
