Then, turn off the power switch and disconnect the power cable from the AC outlet.
Don't touch the plug with wet hand.
When disconnecting the power cable from the outlet, make sure to do it by holding
the plug.
If the cable is pulled for disconnection, it may not only break the cable but also cause
fire and electric shock.
In the case the instrument is replaced with a circulating constant temperature bath,
drain out water from tubes and disconnect the tube connected to the prism section
from the nozzle in the side of the prism before starting prism replacement.
Make sure to replace the prism with a genuine prism as specified by ATAGO.
