Then, check whether the desired place of installation meets the following space requirements:
1) minimum 30 cm (12 inches) distance from any wall or other devices
2) minimum 1.2 m free space in front of the door
3) minimum 1.5 m distance from any heat sources

１２
⚫Never install or use this equipment in explosive atmospheres.
⚫Never install or use this equipment near to hazardous or flammable substances.
⚫Never expose this equipment to direct sunlight.
⚫Never install this equipment near any device that generates high frequency noises.
⚫Considering the heavy weight of this equipment, use a proper device when lifting it.
3.4 Moving and Leveling
This equipment is equipped with four high-quality level casters shown below which combines
three mounting requirements into one: leveling adjustment, caster mobility, and vibration
control.
To move the equipment, turn the height adjustment handles to raise the anti-vibration rubber
feet. If the adjustment handle is too tight to turn due to heavy load, use a wrench to turn the
nut under the handle instead.
After moving the equipment to the installation site, use the adjustment handles to level the
unit and also to lock the rubber feet in place. The leveling procedures are as follows:
1) Place the equipment to the desired location.

adjustment
handle
anti-vibration
rubber foot

１３
2) Turn all 4 height adjustment handles counter-clockwise until the rubber feet touch the
ground.
3) Then, turn all 4 height adjustment handles about 90o degree more so that the caster is
about 10 mm(0.39”) above the ground as shown below:
4) Check whether the equipment is level side-to-side as well as front-to-back by placing a
bubble level on top of the equipment.
5) If not, adjust the height of the rubber foot appropriately until the equipment is level.
3.5 Power Connection
⚫Check electrical requirements in the operation manual or on the ID plate attached
to the top of this equipment before use.
⚫Make sure to use the power cord that comes with your equipment.
⚫In order to prevent fire or power cord damage due to overloading, do not use power
strips or improper extension cords.

１４
The power connection procedures are as follows:
1) Before connecting the power cord, make sure that the main power switch is turned off.
2) Plug the power cords into the power sockets at the back of this equipment.
3) Plug the other end into a properly grounded and dedicated power outlet nearby.
3.6 Operating Conditions
This equipment is designed for indoor use in laboratory environments and to be operated
only by properly trained staff knowledgeable in safe laboratory practices.
The operating conditions for this equipment are as follows:
Permissible Ambient Temperature
18 to 30℃(64.4 to 86°F)
Permissible Relative Humidity
up to 80%
Permissible Altitude
0 to 2,000 m (6,562 ft)
3.7 Required Checking before Operation
⚫Check whether the equipment is installed on a flat, stable, clean, non-slip, dry, and
fireproof surface inside a lab with proper safety measures.
⚫Check whether the equipment is level and fixed properly by the rubber feet.
⚫Check whether the minimum distance (30 cm) from any other devices is observed.
⚫Check whether any device which can be affected by the motor vibrations is placed
near this unit.

１５
