2. Before using the unit
Precautions on installation
13. When you use an antifreeze liquid
Never use an ignitable, toxic or corrosive liquid.
Never use glycerin or ethylene glycol.
For a lower temperature range, use ethyl alcohol only and be sure to operate at 20
℃
or
lower by employing a cooling coil and a throw-in type cooler.
14. Use a stainless steel bath for 14.80
℃
or higher temperatures
The withstand temperature of the testing bath included is 80
℃
(Lower limit temperature:
－
5
℃
). Purchase the optional stainless steel bath if you are going to operate the unit at a
temperature other than that.
15. Check the water level
Keep the water level shown in the right figure. (The vertical
axis in the figure indicates the depth from the top part of the
testing bath)
If the water level is below 20mm, water flow during stirring may
cause water overflow and when the water level goes down by
60mm or more, the water level detection sensor is activated to
stop temperature control.
When you use a silicone oil with BF600, take care not to make
it overflow from increased volume at a higher temperature.

16. Cautions on draining
Do not incline the testing bath to drain with the BF unit installed to it. The BF unit may detach
from the testing bath and may lead to damages or a malfunction.
①
Turn the power switch off at the rear of the BF unit.
②
Remove the power plug from the outlet.
③
Turn the fixing knob anticlockwise by several turns.
④
Remove the BF unit.
⑤
Drain water of the testing bath.
⑥
Refer to the section on P5 “Do not over-tighten the fixing knob.” for the installation of the BF
unit to the testing bath.
