2. Before operating the Equipment
Precautions when installing the Equipment
7. Connect Power Cord/Power Cable to receptacle or switch board of facilities.
Connect Power Cord/Power Cable to suitable receptacle/switch board of facilities according to
electrical requirements as follows.
Electrical
requirements:：
BF200/400/500 AC100V 11A ,BF600 AC100V 13A
＊Check line voltage of its receptacle/switch board of facilities and/or whether utilize the same
line with other equipment or not, if this Equipment does not start up/operate even to turn Earth
Leakage Breaker(ELB) On(｜). Take correct action for the solution, such as changing its
power source away from other equipment.
May drop input voltage to this Equipment and cause to degrade its heating and also temperature
control performance, if multiple power plugs/power cables are connected with single outlet.
Never disassemble nor modify this Equipment. Those actions may cause this Equipment
malfunction, fire or electric shock.
8. Take care for handling of the power cord.
Never operate this Equipment at bundled Power Cord/Power Cable. May heat its Cord/Cable
and then cause fire, if operate at bundled it.
Do not modify, bend forcibly, twist or pull Power Cord/PowerCable. Otherwise, may cause fire
and/or electrical shock.
Do not damage Power Cord/Power Cable by setting under any desk and/or chairs, or by
pinching it between objects. Otherwise, may cause fire and/or electrical shock.
Do not place Power Cord/Power Cable close to kerosene heater, electric heater, or other
heat-generating devices. Insulation of Power Cord/Power Cable may burn and cause fire or
electrical shock.
Turn immediately off Earth Leakage Breaker (ELB) and also disconnect Power Plug/breaker
of switch board of facilities, if it is damaged such as exposure of core wire or disconnection.
May cause fire or electrical shock, if this Equipment is operated with damaged Power
Cord/Power Cable.
Ask local dealer to replace Power Cord/Power Cable.
Connect Power Cord/Power Cable to appropriate receptacle or switch board of facilities.
9. Do not over-tighten the fixing knob.
Over-tightening the fixing knob may deform the testing bath.
②Place the BF unit on the testing bath.
③Turn the fixing knob clockwise to tighten
until there is no gap between the rear of
the pump cover and the side of the testing
bath.
Do not tighten it any further.

2. Before using the unit
Precautions on installation
10. Do not splash water on the unit
11. Do not use well water
Never splash water on electric
components to avoid possible electric
leakage or an electric shock.
Use distilled water or pure water to use in
the testing bath. Well water or low quality
water will make scale or stone
accumulate inside the heater and the
pump, which compromises their
performance or causes a malfunction.

12. When you use a silicon oil
You cannot use silicon oils on any models other than
BF600, which supports silicon oils. Using a silicon oil on a
model other than BF600 will subject the stirrer motor under
burden leading to overheat or a malfunction. Use a silicon
oil when the set temperature is 80℃or higher.
Use a silicone oil whose viscosity is 50cst or less. If
you use a silicon oil of a high viscosity, preheat to lower
the viscosity before using BF600.
Select a silicone oil designed especially for heat medium and with an open-system silicone oil
(heat-resistance dimethyl silicone oil) viscosity of 100 ㎜2/s (cSt).
Recommended silicone oil：
Operating temperature is 200℃or lower Toshiba Silicone TSF458-50

The degradation rate (viscosity change) of a silicone oil will differ depending on the
temperature used.
In particular, the TSF485-100 that is used at over 200℃, viscosity shows almost no changes
at 200℃, the normally operated temperature and about 1000 hours at 250℃and about 100
hours at 270℃.
Contact the silicone oil manufacturer for details.

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.
Reference: 25℃→10.0ℓ 180℃→11.5ℓ
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.
①Turn the power switch off at the rear of the BF unit.
②Remove the power plug from the outlet.
③Turn the fixing knob anticlockwise by several turns.
④Remove the BF unit.
⑤Drain water of the testing bath.
⑥Refer to the section on P5 “Do not over-tighten the fixing knob.” for the installation of the BF
unit to the testing bath.
