・Put the designated dust filter at the inlet of sample tubing if it is used other than clean room.
Keep away the system from direct sun drought or where the temperature of the
system is drastically changed.
The system consists of fine electronics parts.
Install them where to be stable not to crush or fall down.
Keep the system from the equipment which may give a high frequency in the
surroundings and install it.
・Do not put the system jointly each. ・Do not wire the cable in parallel nor take
