Environmental Express HotBlock
TM
Pro Series
Environmental Express HotBlock™ Pro™ Series provides an efficient method of digesting and storing water, wastewater,
soil and sludge samples for metals analysis. These innovative digestion systems allow samples to be digested in a corrosion-
free environment using an external touch screen controller. Samples are handled in a small area with minimal radiant
heat loss. Users should be aware of potential dangers from heating certain types of compounds. Such hazards may include
explosion or the release of toxic or flammable gases.
Definitions/Markings
Each HotBlock
TM
Pro displays certain markings and symbols. All personnel working with the HotBlock™ Pro™s should
have an understanding of the following symbols and definitions:
• V = voltage
• ~ = alternating current
• Hz = frequency
• A = amperes
This symbol means Caution

Installation of your HotBlock
TM
Pro:
1. Plug the controller into an appropriate outlet. The HotBlock
TM
Pro must be plugged into a 20AMP receptacle.
2. The cord running from Block 1 plugs into the corresponding receptacle on the back of the controller. If using two
blocks, attach the cord from Block 2 to the controller in the appropriate receptacle.
If external thermocouple probes (optional) are NOT being used insert the two plugs included into the RTD1 and
RTD2 receptacles on the back of the controller.
If external thermocouple probes ARE to be used insert your probe plugs into these receptacles. RTD1 receptacle
corresponds to Block 1.
3. The HotBlock
TM
or blocks should be located in a vented enclosure while the controller must remain outside the
enclosure for ease of operation and to keep the controller removed from the corrosive digestion environment. (See
installation requirements, page 6).
Failure to locate your HotBlock
TM
controller outside the fume hood will void your product warranty.
