How to operate
4. How to Operate
Power Lamp
Temperature Dial
1. Pour adequate water (3000ml for BM110, 5000ml for BM210) into the tank, and place a thermometer
in the holder. Use distilled water. Deionized water should not be used.
2. Connect the unit securely to a power source with AC230V. Always use a grounded outlet. Set the
temperature dial to the desired temperature and turn on the power switch. The power lamp is lit when
the power heater is on.
3. The temperature scale shows an approxim ate figure. When the temperatur e rises close to the set
point, read the thermometer to adjust the temperature. Since there are some differences from the set
point the first time, check if the current temperature accords with the degree to operate.
This unit does not have a stirring function and the tank tem perature varies . We recomm end you to use
any stirrer (our Lab. Stirrer etc.,) together with this unit.
Power Failure
When power supply is restor ed after a power failure, the unit re-starts operation from previously set
temperature.

Daily maintenance/Weekly maintenance
Do not disjoint the unit
Never modify the unit. There are some highvoltage areas inside the unit, which could cause
electric shock. Request Yamato Scientific for
internal check, adjustment or repair.
Maintenance
5. Maintenance
Daily Maintenance
Turn power switch off and disconnect main power cord before attempting any maintenance.
Once the water bath has cooled to room temperature you may empty the water.
Wipe off any excess dirt on the interior and exterior with a damp cloth. Do not use benzene,
thinner or cleanser.
Weekly Maintenance
The pipe heater should be cleaned at least twice a month. Accumulation of scale build up
results in poor heat transfer and high sheath temperatures.
:
:
When the unit is not in use for a long period of time.
Be sure to disconnect main power and drain the water tank if the unit will not be used for a long
period of time.
