HotBlock™ Pro™: Operation and Instruction Manual Installation, Safety & Maintenance
Electrical Requirements
Required Voltage: 120 volts, ~60Hz,
Current: 9A per block
(all
HotBlock TM Pros are also available in 240V with CE mark)
The HotBlock TM Pro controller is supplied with a 20A male electrical plug. This safety feature requires that the unit is
connected to a 20A receptacle.
Power should not vary greater than±10%. Connecting to the power supply must be done with the supplied heat-resistant
power cord or equivalent.
For safety reasons, a separate power receptacle should be provided for HotBlock TM Pro system. Do not use extension cords
or outlet adaptors. Make certain that power outlets are earth-grounded at the grounding pin.
Potential Hazards:
The HotBlock TM Pro should only be operated by properly trained personnel using standard laboratory safety practices.
Use extreme caution when operating the HotBlock TM Pro digestion blocks. Plastic and graphite surfaces of the blocks may
be too hot to safely touch with bare hands.
The HotBlock TM Pro components contain 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 HotBlock TM Pro 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 TM Pro system. See specifications for individual components.
Users should be aware of potential dangers from heating certain types of compounds. Such dangers may include the
release of toxic or flammable gases or explosion.
Maintenance:
Any service inquiries should be directed to Environmental Express Inc. 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 TM Pro.
Avoid excessive spills, as liquid allowed to overflow into the HotBlock TM Pro casing can seriously damage electronic
components.
