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
and 25 lbs. (11.3 kg) on the 7” x 7” 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. Localized heater element temperature can be
significantly higher than the temperature indicated on
the display. If flammable concentrations reach internal
element, a fire could 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.
