Your isher Isotemp Hotplate, Stirrer or Stirring Hot Plate
has been designed with function, reliability, and safety in
mind. It is your responsibility to install it in conformance
with local electrical codes. or safe operation, please pay
attention to the alert signals throughout the manual.
Warning: These products should be used only under the
operating conditions specified in the Operating Manual.
Always use safe laboratory practices and do not leave the
hotplate in operation while unattended as product fun-
cionality or laboratory practice failures could occur that
might lead to uncontrolled or excessive heating of the top
surface. Safety procedures (including, but not limited to,
unplugging when not in use) and response plans should
be put in place to address the worst case possibility. If an
over-temperature failure occurs, the top surface tempera-
ture could rise to the maximum temperature (300-540°C
depending on your model’s specification) and remain at
that temperature indefinitely. Under these conditions, the
material being heated on the surface of the hotplate could
reach levels in excess of the maximum temperature.
This manual contains important operating and safety
information. The user must carefully read and understand
the contents of this manual prior to the use of this equip-
ment.
Warnings
o avoid electrical shock, always:
1. Use a properly grounded electrical outlet of cor-
rect voltage and current handling capacity.
2. Disconnect from the power supply prior to main-
tenance and servicing.
o avoid personal injury:
1. Do not use in the presence of flammable or
combustible materials — fire or explosion may
result. This device contains components which
may ignite such materials. Not rated for use in
hazardous atmospheres.
2. Use caution when heating volatile materials; top
surface and element can reach the “ lash Point
Temperature” of many chemicals. These stirring

Safety Information
Warning
Warnings alert you to a possibility of per-
sonal injury.
Caution
Cautions alert you to a possibility of
damage to the equipment.
Hot Surface
Hot surfaces alert you to a possibility of

of time after use.
Alert Signals
Warning
Refer servicing to qualified personnel.
Note
If the equipment is used in a manner
not specified by the manufacturer the
protection provided by the equipment
may be impaired.

hotplates are not explosion proof. ire or explo-
sion may result. Unit contains components
which may ignite such materials.
3. Keep top surface clean. Use a non-abrasive
cleaner. Alkali spills, hydrofluoric acid spills or
phosphoric acid spills may damage top and lead
to thermal failure. Unplug unit and remove spills
promptly. Do not immerse unit for cleaning.
4. Replace the top immediately if damaged by
etching, scratching or chipping. A damaged top
can break in use.
5. Do not use metal foil on hotplate which may
block air flow. Overheating will result.
6. Do not remove or modify grounded power plug.
Use only properly grounded outlets to avoid
shock hazard.
7. Use appropriate hand and eye protection when
handling hazardous chemicals.
8. Gross weight of items placed on top of stirrers
should not exceed 25 lbs. (11.3 kg).
9. The top plate of the unit can remain hot for
some time after use. A “CAUTION - HOT TOP”
light will remain on until top plate temperature
cools to below 50°C.
10. Do not leave an active probe out of the fluid.
This may cause uncontrolled heating of the fluid
on the hotplate and unintentional boiling or an
explosion could occur.
11. Note that the exterior housing will be hot during
and for a period of time after use.
12. Refer servicing to qualified personnel.
