CA-200 IMPORTANT SAFEGUARDS AND PRECAUTIONS

IMPORTANT SAFEGUARDS AND PRECAUTIONS

WARNING

Place Model CA-200 at the place where temperature is 5 to 40 degrees Celsius and

humidity is under 80%. The placement except these conditions causes troubles.

WARNING

Ground a power cable ground line or a ground terminal surely.

By touching the metal of Model CA-200 without grounding, you can get an electric

shock.

WARNING

As it thunders, do not connect a power cable. Danger of an electric shock by lightning

CAUTION

Do not place things infront of Model CA-200. When things are placed, the power switch

of the unit can’t be turned off emergently and accidents can be caused.

CAUTION

Do not connect many cords into outlets. Danger of a fire by outlet overheat

CAUTION

Place Model CA-200 at the place free from water, humidity, dust, and oily smoke.

Danger of a fire, breakage, and an electric shock

WARNING

Model CA-200 is not explosion prevention, so do not place flammable material near

Model CA-200. The placement except these conditions causes a fire and

an explosion.

IMPORTANT SAFEGUARDS AND PRECAUTIONS CA-200

WARNING

After stopping the unit or at the parts change, repair, and inspection, pull off the main

power plug necessarily to avoid an electrical shock.

WARNING

Pull out a power plug while holding it not to disconnect or short-circuit in a plug or a

cord.

WARNING

Put on protective goggles and gloves necessarily when using reagents. Without putting

on them, skin disorder and blindness can be caused.

CAUTION

Do not impact exposed glass not to break it. Fragments and scatter cause accidents.

WARNING

Never disassemble or remodel the unit. Contact our distributors if necessary.

WARNING

When a trouble happens, immediately notify the fact to the person in charge and take an

emergency measure. If the cause is unclear or the problemis not solved, never restart the

unit.
