Soil-Cell: Operation and Instruction Manual About Your HotBlock
TM
Potential Hazards:
The HotBlock
TM
should only be operated by properly trained personnel using standard laboratory safety practices.
Use extreme caution when operating the HotBlock
TM
. Plastic and graphite surfaces of the HotBlock
TM
may be too hot to
safely touch with bare hands.
The HotBlock
TM
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 specications for power requirements.
Application of the wrong supply voltage can create a re hazard and a potentially serious shock hazard, and could
seriously damage the HotBlock
TM
system. See specications 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 ammable gases.
Always lift the HotBlock
TM
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 conrm the proposed method will not damage your HotBlock
TM
.
Avoid excessive spills, as liquid allowed to overow into the HotBlock
TM
casing can severely damage electronic
components.
