■ Important Instructions
● Installation Environment
Environmental test chambers are precision apparatuses. In order to maintain reliable performance for the
long term, please prepare a suitable installation environment by observing the following instructions.
32℃. (recommended)
〇 Maintain the room temperature of the installation site within the range of ＋10℃ to
This chamber comes with air-cooled refrigerator. As ambient temperature increases, the refrigeration
capacity gradually decreases and basic performance will be affected, such as not being able to reach
minimum temperature. Once ambient temperature exceeds +40℃, temperature around the temperature control
instruments in the electric board increases, causing the protective device to trip and shut down the instruments. On the
other hand, if an ambient temperature falls below +0℃, humidification water in the water circuit will freeze,
or overcooled refrigerant which circulates inside the refrigeration circuit may cause failure.
〇 When using the chamber inside a closed room, be sure to turn on the air conditioner.
Warm air is exhausted from the refrigerator which is mounted inside the chamber during the operation. If
warm air continues to exhaust in a closed-up room, the room temperature will gradually increase and the
chamber as well as other measuring instruments may be adversely affected. (Please refer to the
specifications table of respective model for the amount of heat exhaust.)
〇 Door packing or circumference of the cable port may condensate during a
low-temperature operation.
During a low temperature operation, condensation may occur around the door packing depending on the
ambient temperature at the time. Moreover, if the silicon stopper of the cable port is not tightly fitted in,
external air may enter inside the chamber, causing frost formation.
〇 Be careful not to change ambient temperature suddenly.
If a chamber is placed in an area from where external air can directly enter inside the chamber such as near
a door, temperature measurements may be temporarily affected causing control failure.
〇 Do not expose the chamber to direct sunlight.
This may cause breakdown, malfunction, or inaccurate measurement.
〇 Do not directly expose the chamber to hot or cold air from air conditioners or any other
apparatus.
This may cause breakdown, malfunction, or control failure.
11
〇 Do not use the chamber in a corrosive or explosive atmosphere.
This may cause breakdown, malfunction, or deterioration. Also, this may cause accidental explosions. This device does not
have explosion-proof construction.
〇 Do not place the chamber near equipment that may cause noise.
This may cause breakdown, malfunction, or control failure.
〇 Do not install the chamber in a dusty place.
This may cause breakdown, malfunction, or control failure.
〇 Do not install the chamber in a place where vibrations can be felt.
This may cause breakdown, malfunction, or control failure.
〇 Install the chamber on a level floor.
If the chamber is not placed on the level, both humidification water level control and water drainage will be affected. Make sure
to check the levelness of the chamber using the bubble level or another instrument when installing or transferring the chamber.
〇 Do not place any objects which can obstruct air exhaust on the roof.
This may cause overheating of the refrigerator or electric apparatus, resulting in an abnormal stop of the
chamber.
〇 Do not place any objects which can obstruct air suction at the front.
This may cause overheating of the refrigerator or electric apparatus, resulting in an abnormal stop of the
chamber.

〇 Chamber installation space
For air suction/exhaust of the refrigerator and for opening/closing the door, the following space needs to
be secured.
◇ Minimum space required for normal usage
* Sufficient space must be secured on the right side because operators need to frequently access this side in order to connect external output
terminals, LAN cable, earth leakage breaker, and water circuit switching valve.
◇ Space required for repair and inspections
13
- Caution -
1. Please consult us for required installation space if optional items such as cable port are added.
2. If the humidification water direct feed system (optional: directly connected to tap water or to the purifier) is used,
600mm or more is required at the back of the chamber.
* In order to perform maintenance work, minimum space of 600mm is required. If it is not possible
to move the chamber forward, please make sure to secure the said space.
● Precautions for handling specimens
〇 Do not place dangerous specimens inside the chamber.
Never place the explosive and inflammable materials shown in Table 1 inside the chamber. This may cause an explosion hazard.
In addition, never place the specimens or jigs if their ignition point is below 180℃. This may cause smoking or fire.
〇 Do not place specimens which generate corrosive gases such as SOx and NOx in the chamber.
Do not use specimens that generate corrosive gases such as sulfur dioxide because such specimens deteriorate the materials of the
chamber.
〇 When applying voltage to specimens, use the interlock terminal.
If the chamber is stopped due to some reason, temperature inside the chamber will increase due to self-heating of. specimens,
resulting in burning of the specimens. (For more details, please refer to P27 "Interlock".)
〇 This chamber should not be used for the tests which require a clean atmosphere.
This chamber does not control the degree of cleanliness like a clean room.
〇 Please prevent the formation of condensation on the specimens.
While temperature (humidity) is rising, air temperature inside the chamber and the specimen's temperature do not rise
simultaneously. After air temperature inside the chamber rises, specimen temperature will rise subsequently. Time difference
will vary depending on the materials and quantity of specimens. If specimen temperature becomes lower than the dew-point
temperature of the air temperature at the point of time while temperature is rising, the specimen will condensate. In order to
avoid condensation of specimens, take note of the following points.
Countermeasure 1 Do not suddenly increase temperature (humidity)
Set temperature (humidity) ramp-up rate using program operation mode so that temperature (humidity) will not suddenly
increase during an operation.
For example, in the case of performing a high humidity operation such as +85 ℃/85%RH, it is necessary to gradually increase temperature up
to +85 ℃ first, then increase humidity about 10 to 30 minutes later.
Countermeasure 2 Do not leave specimens inside the chamber after a temperature/humidity test is completed.
If specimens are left inside the chamber after a test is stopped, relative humidity inside the chamber may naturally increase up to 100%RH. Be
sure to restore standard conditions inside the chamber such as +23℃ once a test is completed and remove specimens.
14
- Caution -
Placing too many specimens inside the chamber to the extent that airflow is blocked in the area will affect the air circulation, leading to
partial overheating around the thermal heater area, and this will cause Er01 (overheat) to occur.
Countermeasures 3 Try not to open the door while a low temperature test is being performed (below dew-point temperature)
so that specimens are not exposed to open air.
[Example] When the environment is 23 ℃/65%RH, the dew-point temperature is 16 ℃. Under this circumstance, if the door is opened
when the temperature inside the chamber is below 16℃, the internal surface of the chamber and specimens will condensate.
Countermeasure 4 Do not place specimens carelessly inside the chamber when a temperature/humidity test is performed
(below dew-point temperature).
[Example] When a test is performed at 40℃/80%, the dew-point temperature inside the chamber is 35.9℃. Under this circumstance, if the
specimens which have a surface temperature of less than 35.9℃ are placed inside the chamber, these specimens will
condensate. (It is presumed that inside the chamber is kept at 40℃/80% for a while after the door is opened.)
○ Place specimens in such a manner that the air circulation in the test area is not obstructed.
Air inside the chamber is forcibly circulated in order to keep temperature (humidity) uniform. Blocking the airflow will affect
uniformity of temperature (humidity).
15
● Handling Instructions
○ Do not repeatedly turn on and off the power switch of the main body.
Excessive turning on/off of the switch during an operation may cause failure of the device.
○ In order to protect specimens, be sure to set the overheat protector.
If the setting is not performed, an operation will not stop even if the temperature inside the chamber is abnormal until it exceeds 110℃ (180℃ for
150℃ specification models).
○ Set +5 ℃ or higher temperature as the upper temperature limit (main controller built-in function).
If the limit is too low, the chamber may temporarily malfunction due to control failure.
○ The USB connector is only meant for a USB memory.
Do not connect and charge other devices (such as a tablet PC or a handheld device). Depending on the specifications of the connected
device, the WEB board may fail due to current surge.
16
- Caution -
Placing explosive substances, flammable substances, or other substances containing materials indicated in Schedule 1
inside the chamber may cause an explosion. We will not bear any responsibility related the risks of dangerous
specimens used.

● Operating Instructions
○ Instantaneous voltage drop
When voltage of the main power suddenly drops due to a lightning, etc., the connected PC may be affected. In order to avoid
such a circumstance, it is advisable to use a UPS for your PC.
○ Discharge humidification water from the subtank if temperature/humidity operation is not performed for
more than two weeks.
Discharge humidification water from the subtank if temperature/humidity operation is not performed for more than two weeks. If not, bacteria
may breed inside the tank.
○ Do not operate the chamber without closing back/side service panels.
Otherwise, electrical shocks, burns, and injuries may be caused.
○ When the chamber is operated with temperature setting only, humidity is not controlled.
For the specimen that requires strict humidity control, please make sure to set the humidity as well.
O Be sure to maintain humidification water pressure between 0.07MPa and 0.5MPa. (In the case of the
humidification system direct connection circuit which does not use a water tank.)
If water supply pressure is too low, water will not be supplied smoothly. On the other hand, if the pressure is too high, leakage
may occur.
O Make sure to use clean humidification water such as ion-exchanged water with an electric conductivity of
less than 0.1 to 10μS/cm or pure water.
If normal tap water is supplied directly, the life of the humidification heater or wick gauze may become significantly shorter.
【Remark】
Quality of humidification water will greatly affect the life of various components inside the chamber as well as reliability test results.
Deterioration of water quality will cause scale to deposit inside the humidifying pan, shortening the life of the humidification heater.
At the same time, water absorbency of a wick will weaken, resulting in larger measurement deviation of humidity. (See below)
18
Fire Alarm
Hot Air
○ Countermeasures to prevent overheating and overcooling while temperature is increasing and decreasing
If the shortest temperature ramp-up or ramp-down time is set during a program operation, temperature will increase or decrease
with the maximum capacity to reach the target temperature. Therefore, there is a possibility of overshooting or undershooting the target
temperature by about 1 to 2℃ when the set temperature/humidity is reached. This problem can be prevented by setting the ramp-up or
ramp-down rate slower than 0.5℃ /minute. Please note that releasing the delayed humidification function of a local control
operation will cause the temperature to increase or decrease with the maximum ramp-up or ramp-down rate in order to reach the
target temperature.
○ Do not open and close the door during a high temperature/high humidity
operation.
Opening the door during high temperature/high humidity tests may cause the following
dangers.
・ Hot air may blow out and burn your skin.
・ As the internal surface of the door is heated, you may burn your skin by touching it.
・ Installing this device just below a fire alarm mounted on the ceiling may cause the
alarm to accidentally activate.
○ Do not unnecessarily open and close the door during a low temperature operation.
Opening the door during low temperature tests may cause the following dangers.
・ Temperature may increase and exceed the set upper limit, causing Er09 to be displayed and the operation to be
stopped.
・ Specimens will condensate.
・ The frost on the surface of the chiller inside the chamber will grow.
○ Take necessary precautions to prevent condensation inside the chiller when temperature inside the
chamber is less than O +35℃ (See P.41 Defrosting method).
In order to maintain the temperature/humidity, a chiller (evaporator) is placed inside the chamber. This chiller consists of numerous
aluminum boards which are overlapped in a several millimeter pitch, and its surface temperature is very low (-45℃ to 0℃) when the temperature
inside the chamber is between -40℃ and +35℃. Because air inside the chamber repeatedly passes through these aluminum boards,
moisture inside the chamber develops into frost on the surface of the chiller and then gradually becomes bigger to form ice.
This ice will cover the cold surface of the chiller, or block air circulation, deteriorating the heat exchanging performance of the
chiller, and as a result, cooling or dehumidification performance will be affected. These frost formations of the chiller will more
commonly happen in the following cases.
・ The door is opened / closed during a low temperature operation, or a cable port is not properly sealed allowing external air
to enter.
・ Temperature/humidity operation at below 35℃ (Because humidification steam will form frost on the surface of the chiller, long hours of
continuous operation is not recommended. If such a test is necessary, please consult us.)

● Precautions for disposal
(recovery and decomposition of fluorocarbon refrigerant）
The fluorocarbon refrigerant used in the refrigeration circuit of this chamber must be recovered and decomposed according to the Fluorocarbons
Recovery and Destruction Act (a law which stipulates the collection and the decomposition of fluorocarbons used in certain products).
In order to control discharge of fluorocarbons into the atmosphere through proper recovery and destruction, it is prohibited to
discharge three types of fluorocarbons; chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), and hydrofluorocarbon
(HFC) which are used for commercial-use air conditioners as refrigerants, into atmospheric air. At the same time, recovery and
destruction of these fluorocarbons at the time of disposal of a device, introduction of a device disposal procedures control system
(to document detailed procedures on disposing fluorocarbons), and clarification of responsibility for collecting old refrigerant at
the time of maintenance are required under this law. Because necessary procedures need to be carried out by professional
contractors who are certified by the refrigerant recovery office of each local government, please contact our customer support
center at the time of disposal.

Water tube
- Caution -
1. When removing the water tank, be sure to disconnect the connector first. Lifting up the water tank with the
connector connected may cause the water hose to damage resulting in a water leak.
Please handle the water tube connecter with care as any damage of the tip may obstruct the water supply.
3. There is a φ2.5 vent hole on the water tank cover. Be careful not to close this hole with tape, etc. If this vent hole is
blocked and a test is performed, water will not be smoothly supplied, causing temperature and humidity control failure.
Also, do not turn the water tank sideways with water inside. Humidification water will flow out of the φ2.5 vent hole.
4. Make sure to use clean humidification water such as ion-exchanged water with electric conductivity of less than 0.1
to 10μS/cm or pure water.
■ Preparing for Operation
1. Installing the chamber
① Use a level or another instrument to check if the internal floor inside the chamber is on the level, and if not, adjust the
levelness using adjusters mounted on each leg of the main body.
② Be sure to lower these adjusters until all of them touch the floor.
2. Preparing humidification water (FX type)
① Open the door in front at the bottom and pull out the water tank table.
② Remove the water tube connector located at the bottom right of the water tank. (Press the button of the water tube
connector)
③ Remove the water tank.
④ Supply pure water or ion exchanged water (0.1 to 10μS/cm ) in the water tank. (If a purifier (optional) is equipped, use tap
water.)
⑤ Reattach the water tank on the water tank table.
⑥ Attach the water tube connector back to the water tank.
⑦ Push the water tank table back to the original position.
⑧ Close the door.

Drain hose 1
Drain hose 2
- Caution -
1. Make sure that the tip of the drainage hose is exposed to air but not soaked in water, such as in a drain pan or
drain pipe.
2. When using the drain pan, do not face the tip of the drain hose toward other equipment or persons because hot air or hot steam
may spout from the drain hose when the door is closed.
- Caution -
When using a tap water direct feed system or purifier direct feed system (optional), be sure to firmly connect both drain
hose 1 and drain hose 2 to the drain pipe, and do not use the drain pan. If the water circuit fails, humidification water
may continue to overflow.
3. Connecting drain hoses
Tightly connect two drain hoses. Functions of drain hose 1 and drain hose 2 are as follows. For drainage, prepare an around
10-liter container to receive discharge water and throw it away periodically, or connect a drain pipe (recommended).
【Drain hose 1】
① The humidification water inside the chamber will be drained automatically when the following circumstances occur.
About 1 liter of water is drained at a time.
・ The temperature inside the chamber is below +3℃ or above +97℃.
・ The chamber is left untouched for more than one hour after an operation is stopped.
・ When a temperature test is started with the local controller (main body's controller on the door).
・ When more than two steps of a programmed temperature test (by using the remote controller) are continuously
performed.
② During a temperature/humidity operation, vapor in the chamber condenses inside the drain hose and the accumulated
liquid is drained out. Generally, the higher the temperature and humidity are, drainage volume will increase.
If the humidification vapor collection system is not used, discharge volume resulted from an 85℃, 85% RH operation is
about 600ml to 800ml per day.
【Drain hose 2】
Types of water to be drained out are as follows.
・ Condensation water collected in the moisture trap at the bottom of the door and the refrigerator
drain pan
Drainage volume from a temperature/humidity operation is around 0 to 100ml per day depending on the
conditions of the operation.
・ Humidification water in the subtank
If no temperature/humidity operation is performed for more than two
weeks, humidification water in the subtank needs to be discharged
manually. Volume is about 350 ml at a time.

- Caution -
1. The primary power source should fulfill the following requirements - noise level: ± 1.5kV, frequency variation
range: ±1%, voltage variation range: AC200V±5%.
2. Use a commercial power source without much voltage variation as the primary power source. The power
generated by the generator, etc., tends to have waveform distortion. If effective voltage is not supplied, the
refrigerator may stop.
3. An operation may stop when a momentary power failure occurs. Depending on the type of load applied to the
refrigerator, even a slight momentary power failure (0.05 seconds) after a thunderbolt may cause an operation to
stop.
4. Use the primary breaker which can shut down the current within one second once it detects over 500% of the rated
current.
5. Be sure to connect the ground wire in order to prevent an electric shock. Do not connect the ground wire to the
town gas pipe or LPG pipe.
6. Do not share the ground wire with other equipment which do not come with an earth leakage breaker.
7. Make sure that the electrical potential between S-phase and the ground is less than 3V.

4. Connecting the power
The power source specification of this chamber is AC200V ± 10％, 3-phase, 50/60Hz.
Remove the service panel on the right side and firmly connect the specified cable in the table below with the earth leakage breaker.
① Open the service panel indicated in the figure on the right.
② Remove the breaker cover.
③ Connect the power cable to the primary side of the earth leakage breaker
④ Reattach the breaker cover.
⑤ Connect the ground to the grounding terminal.
⑥ Reattach the service panel.
25
- Caution -
When turning off the power after a dry run is completed, turn off the power switch first before turning off the earth leakage breaker.
If the earth leakage breaker is turned off before the power switch is turned off, the power failure alarm message AL84
will be displayed and an intermittent buzzer will go off from the control panel when the power is turned on. In such a
case, reset the alarm.
5. Starting an operation
① Open the door and attach a wick gauze to the sensor (not required for FL type).
② Turn on the earth leakage breaker (on the side of the main body) and the power switch at the front of the main body in order.
③ Be sure to set temperature/humidity such as +20℃/60%RH first before starting an operation. As for setting procedures,
please refer to the separate manual titled “Settings and Operating Manual”..
④ Open the door to check if wind is circulating inside the chamber.
⑤ Wait for about 10 minutes to make sure that the water level in the humidification pan has risen enough to cover the
humidification heater and that the water level is stable. If the water level is too low, the humidification heater will overheat
and the protective device may be activated. On the other hand, if the water level is too high, it will not only cause
consumption of humidification water to increase, but also affect humidity control during a high temperature/high humidity test.
As for the humidification pan water level adjustment method, "P86 Inspection upon Relocation"(not required for FL type).
⑥ Once water level in the humidification pan is found to be fine, please check with your fingers if the wick gauze is wet. If the
wick gauze is not wet, or water flows out from the wick pan, please refer to "P86 Inspection upon Relocation".

● Humidification vapor recovery system
The FX type comes with the humidification vapor recovery system as a standard specification. A part of vapor is condensed,
collected, and reused by this system.
In particular, this system is effective for high temperature/humidity operations with high vapor pressure (60℃, 80% or higher). (See Table A)
Table A Examples of water consumption at 85℃, 85%RH operation
[Note 1] The consumption volumes mentioned in the above table are guidelines with the premise that the cable port and door
packing is tightly sealed and those are not guaranteed performance. If cable port, etc., are not tightly sealed, the
recovery rate will reduce substantially.
[Note 2] The higher the temperature and humidity become (for example, 85℃, 85%RH), the higher the recovery rate of the
humidification vapor recovery system becomes, while the recovery rate decreases as temperature and humidity
decrease. When temperature and humidity are below 40℃/95%, the recovery rate is almost equivalent to zero.
[Note 3] The data of Table A is just a reference for chamber operation.
