Operation & Instruction Manual
Getting Started
Environmental Express® HotBlock® TKN System
Environmental Express HotBlock® TKN System provides an efficient method
of digesting and storing water, wastewater, soil and sludge samples for Total
Kjeldahl Nitrogen (TKN) analysis, total phosphorous (TP or TKP); total metals
digestions, or other digestion methods requiring temperature up to 450°C. These
innovative digestion systems allow samples to be digested in a corrosion-free
environment. In addition, 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® TKN unit displays certain markings and symbols. All personnel
working with the unit should have an understanding of the following symbols
and definitions:
• V = voltage
• ~ = alternating current
• Hz = frequency
• A = amperes
Unpacking Your HotBlock® TKN System
1. Remove the HotBlock® TKN from the shipping container by lifting from
the bottom of the block.
2. If you purchased a complete HotBlock® TKN System, you will also
receive a simple manual controller (TKN100) and glass digestion tubes.
If not, order items separately on page 9.
3. Connect the larger gray cable from the block to the controller using the
bottom socket labeled “Block” (touch-screen controller) or the socket
next to the power switch (basic controller).
4. Connect the smaller metal cable to the controller using the top socket
labled “T/C” (touch-screen controller) or the socket on the side of the
controller (basic controller).
5. Insert the dummy plug into the controller in the top socket labeled
“Plug” (touch-screen controller only). The unlabeled socket is not used.
6. Plug the controller into an appropriate 240 VAC outlet.
7. Save original packaging in a dry area for use if unit needs to be
