HotBlock™: Operation and Instruction Manual Potential Hazards and Maintenance
Potential Hazards:
The HotBlock™ should only be operated by properly trained personnel using
standard laboratory safety practices.
Use extreme caution when operating the HotBlock™. Plastic and graphite surfaces
of the HotBlock™ may be too hot to safely touch with bare hands.
The HotBlock™ contains electrical circuits and devices and compounds operating at
dangerous voltages. Contact with these circuits, devices and components can cause
serious injury or painful electric shock.
Proper grounding is essential to avoid a potentially serious electric shock hazard.
Ensure that there is an internal ground connection between the metal base of the
system and the 3-pin, earth-grounded receptacle.
For safety reasons a separate power outlet receptacle should be provided for each
unit in the system. Do not use extension cords or outlet adaptors. Make certain
each power outlet is earth-grounded at the grounding pin.
See individual block specifications for power requirements, pages 3-4.
Application of the wrong supply voltage can create a fire hazard and a potentially
serious shock hazard, and could seriously damage the HotBlock™ system. See
specifications for individual HotBlocks™.
Users should be aware of potential dangers from heating certain types of
compounds. Such dangers may include explosion or the release of toxic or
flammable gases.
Always lift the HotBlock™ from the bottom of the unit.
Maintenance:
Any service inquiries should be directed to Environmental Express Technical Service
Department.
After each use, clean exterior surfaces with a damp sponge to remove acid residue.
For acid spills, sponge with a diluted solution of sodium bicarbonate followed
by distilled water. Acid that is spilled directly into the digestion wells should be
neutralized and removed.
Before using any cleaning or decontamination methods except those
recommended, check with Environmental Express to confirm the proposed method
will not damage your HotBlock™.
Avoid excessive spills, as liquid allowed to overflow into the HotBlock™ casing can
severely damage electronic components.
