2. Before operating the unit
Precautions for installation
3. Never operate the unit in an atmosphere containing flammable or explosive gas.
●
Never operate the unit in an atmosphere containing flammable or explosive gas. Since
This product is not of an explosion-proof structure. Accordingly, when the power switch
on the right side of the unit is turned ON/OFF and in the course of operation, arc may
occur, possibly causing fire and explosion.
●
See the section “13. List of dangerous materials” on page 38 for flammable and explosive
gases.
4. Install on a level surface.
●
If it is not installed level, the leak detection function may not operate properly when
water should leak at the pipes in the unit. The permissible error in the levelness
shall be
±
3 degree and properly set the adjusters of the constant temperature and
humidity chamber or of the laboratory table to make it level.
●
The unit weight is about 17kg. Handle with care during transportation and installation.
5. Take the power supply from the dedicated socket outlet.
●
Use the socket outlet appropriate to the power capacity (1A or larger capacity).
●
The deficient power capacity causes not only decrease in the water supplying rate, but
makes correct control impossible due to drop of the supply voltage. Always connect the
product to the power supply system with sufficient allowance in the supply voltage.
