2.Disconnect from the power supply prior to maintenance
and servicing.
To avoid personal injury:
1.Do not use in the presence of flammable vapors
outside of a fume hood or near combustible materials
where heating could result in a fire or explosion.
This device contains components which may ignite
such materials. This device is not rated for use in
designated hazardous locations where flammable
vapors may reach the lower flammability limit.
2.Use caution when heating volatile materials; top
surface and element can reach the "Flash Point
Temperature" of many chemicals. These hot plates
are not explosion proof. Fire or explosion 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 hot plate which may block air
flow. Overheating will result.
6.Check and tighten the removable cord periodically
making sure it is secure. If loosened, the cord
could become hot and/or spark and be a potential
fire hazard. If cord appears damaged, replace
immediately. If cord is repeatedly loosened it is
recommended to purchase the power cord.

7.Do not remove or modify grounded power plug. Use
only properly grounded outlets to avoid shock hazard.
8.Use appropriate hand and eye protection when
handling hazardous chemicals.
9.Gross weight of items placed on top of hot plates
should not exceed 35 lbs. (15.9 kg.) on the 10" x 10"
models, 25 lbs. (11.3 kg) on the 7" x 7" models and 15
lbs. (6.8 kg) on the 4" x 4" models.
10."Caution: Hot Top. Avoid Contact." 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.
11.Do not leave an active probe out of the fluid. This
may cause uncontrolled heating of the fluid on the hot
plate and unintentional boiling or an explosion could
occur.
12.Do not heat flammable liquids outside of a fume
hood. When heating flammable liquids, heater
element temperature can be significantly higher than
the temperature indicated on the display. If flammable
vapors concentrations reach the internal heating
element a fire or explosion may result.
13.Note that the exterior housing will be hot during and
for a period of time after use.
14.Refer servicing to qualified personnel.
