ESPEC’s environmental labeling “GREEN PRODUCT Label”
ESPEC has been striving for the development of eco-friendly products by establishing
an environmentally conscious design and development guidelines for the prevention
of global warming and pollution and the promotion of resource recycling.
As part of these efforts, in April 2009, we instituted the
“GREEN PRODUCT Label” certification system for the
products intended for the Japanese market.
The “GREEN PRODUCT Label” is equivalent to the
environmental label for self-declared environmental
claims “Type II” established by the International
Organization for Standardization (ISO).
The certification criterion for green product labeling is as follows.
Products which are intended for the domestic market and satisfy the following
requirements:
Area of environmentally
conscious activity Certification criterion
Energy-saving
In comparison with the former model regarding power
consumption, more than 15% energy saving is
achieved. (When the operation pattern specified by
ESPEC is used and compared with the former model)
Energy Saving Advice: Provides tips for energy-saving operation.

3. Installation
Installation site check
This section describes installation site and space requirements.
WARNING
Do not install the chamber outside or improper places.
It may cause fire or electrical shock.
Installation requirements
Install in an area that meets the following conditions:
 On a flat, level floor strong enough to bear the weight of the chamber
 Place subject to minimal mechanical vibrations
 Place of minimum airborne contaminants
 Place free from moisture
 Place free from in flammable materials in the vicinity
 Place free from combustible or corrosive gases
 Place not exposed to direct sunlight but of good ventilation
 Where the ambient temperature is between +5 to +35°C, humidity is max. 75%rh
range shown below (+23°C is optimum).
 Place where ambient temperature does not change 5°C or more in a few
minutes.
 Not directly underneath a fire alarm
 Not near a heat source which generates high temperature
 Close to power, water and drainage utilities
 Altitude not higher than 1000m
Notice
Do not use the chamber under an ambient temperature that is out of the
specified operating range. Doing so may result in malfunction.
The operating condition is between +5C to +35C.

◆ Energy Saving Advice ◆
 Set the operating temperature range according
to outside conditions.
 Make sure that heat exhaustion from the
chamber is not blocked off.
Temperature in the installation site
Keeping an appropriate temperature in the installation site reduces
the load on the refrigerators and heaters imposed by the ambient
temperature.
Notes for installation
List of Center of Gravity Positions
WARNING
When laying the chamber onto the floor, be careful not to catch your
fingers in the chamber, forklift or any other equipment and not to have
the chamber fall down.
When using a forklift, make sure that the front ends of the forks are not
covered by the chamber.

How to install
Notice
Do not move the chamber with specimens inside.
The specimens may turn over or fall off the shelves.
Install the chamber only on a flat, level floor.
An unlevel chamber can possibly cause water to backflow without smooth drainage
from the dew tray, mistakenly trigger alarms, and destabilize humidity control.
Leveling feet are found under each of the four corners of the chamber base.
< Procedure >
1) Turn the adjustable foot until at a height that the chamber sits level.
2) Place a level on the center of the test area floor, and check the level.

4. How to remove moisture absorbents
(export specifications only)
The chamber door is fitted with a retainer before shipping from the factory, so as to
prevent the door from opening during transport. After the chamber has been installed,
detach the retainer.

6. Drainage work
Drainage work is needed to drain water from the humidifying tray and condensation
formed in the test area out of the chamber.
Gravitational drainage is employed for the drainage system.
Keep the drain hose sloped downward to prevent the water from getting stagnant
inside and run the water into a pit.
Location of drain hose: rear underneath.
Drain tube: length about1m from the chamber, O.D. Ø18mm, I.D. Ø12mm
Notice
・
If collecting drainage in a container, regularly check water level to make sure it
does not overflow. If using the continuous water supply or additional water
tank (option), do not drain water into a container.
・
To prevent backflow into the chamber, do not share the drainage line with
other equipment. Also, leave the water tank drain hose and drain pipe ends
open to the atmosphere.
・
Raising the drain pipe about 5 cm or more off the floor or the chamber’s
supporting surface will form a pocket in the line, whereby preventing proper
drainage and possibly causing water to backflow into the dew tray or the
mechanical parts compartment. Also, if any part of the drain pipe is higher
than the drain outlet, water will not drain smoothly, possibly flooding the test
area floor.
< Procedure >
1) Connect the drain pipe from the chamber rear panel to a drainage system or run it
into container or pit. * Drain pipe ID: Ø12 mm
Whenever needed to check, maintain or run the chamber, connect the drain hose
to the nipple and drain water from the chamber. Fit the hose over the nipple and
press inward until hearing the connection catch.

7. Power supply work
Primary power supply requirements
Notice
・ Always take care to comply with your national regulations for power supply
installations. If a drainage pit is not located near the chamber, drain in a container.
・ External power supply cables shall be of approved type and in compliance
with IEC/EN60227 or IEC/EN60245 or any other applicable national regulation.
Prepare the power supply and power cable satisfying the following requirements.

WARNING
When using a leakage beaker as the primary power switch, use one that
supports high harmonics.
Malfunctions can occur with switches that do not support high-harmonics.
Primary power supply connections
The chamber is connected to the primary power supply via the power cable. It is also
grounded to prevent noise from infiltrating electronic circuits and to protect users
against electric shock which can result from leakage current.
WARNING
EXPLOSION! DO NOT ground the equipment on gas pipes.
Grounding of the sort could result in explosion.
DO NOT share ground with equipment not fitted with a leakage breaker.
The chamber's leakage breaker will not trip in the event of overcurrent,
short-circuits or surges.
DO NOT ground between equipment.
The chamber's leakage breaker will not trip in the event of overcurrent,
short-circuits or surges.
Ground the equipment WITHOUT FAIL
Unless the equipment is grounded, the leakage breaker will not trip in the event
current leaks, possibly resulting in electric shock. Furthermore, this will leave the
equipment unprotected against power supply noise. Sometimes, the temperature
(humidity) in the chamber can be destabilized.

For SH/SU-222,242,262
After preparing the primary supply (see above), connect the chamber’s power
cable to the power supply.
For electrical outlet with ground
The chamber is grounded through the power cable when plugged into the
electrical outlet, so separate grounding work is not needed.
220 and 230V AC supplies have a cable with the below plug. Prepare an outlet
on the primary power system to match this plug.
