TKN:
Operation & Instruction Manual
General Information
Safety & Hazard Information
•
The HotBlock® TKN should only be operated by properly trained personnel using standard
laboratory safety practices.
• Review Safety Data Sheets for all materials used or generated during the operation of the
HotBlock® TKN.
• Use extreme caution when operating the HotBlock® TKN. All surfaces of the HotBlock® TKN
may be too hot to safely touch with bare hands.
• It is highly recommended that the HotBlock® TKN should be set up and operated in a chemical
fume hood with a face velocity of not less than 100 fpm.
• The controller is independent from the block and should be placed outside the fume hood to
reduce the likelihood of acid damage.
• The HotBlock® TKN contains electrical circuits and devices and components 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 adapters. Make certain each power outlet is
earth-grounded at the grounding pin.
• See electrical requirements for power specifications, page 4.
• Application of the wrong supply voltage can create a fire hazard and a potentially serious shock
hazard, and could seriously damage the HotBlock® TKN system.
• Wear appropriate Personal Protective Equipment (PPE) suitable for use with caustic and
corrosive materials.
• 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.
•
Avoid breathing any vapors that may come off of the HotBlock® TKN; they may be harmful
or fatal.
• The power should be kept plugged into its outlet until the unit has cooled down.
• If boil over does occur during operation of the HotBlock® TKN, immediately wipe the system
down with neutralizing solution, such as a mild solution of sodium bicarbonate.
• Unplug the HotBlock® TKN from the outlet prior to cleaning exterior surfaces. Wipe with damp
sponge or towel after each use, first with mild sodium bicarbonate or similar solution followed
by DI or distilled water. Avoid solutions on or near the controls.
• Always lift the HotBlock® TKN from the bottom of the unit.
