Environmental Express HotBlock CAL 3300 - Manual (Page 13)

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 4-6.
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.
