General Safety Rules
WARNING. READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions
listed below may result in electrical shock, fire and / or serious personal injury.
SAVE THESE INSTRUCTIONS
Know your instrument – Read the operating manual carefully. Learn the equipment's application and
limitations.
Ground all equipment – This instrument is equipped with a grounding type plug. The green/yellow
conductor in the cord is the grounding wire and should never be connected to a live terminal.
Avoid dangerous environment – Electrical instruments designed to process liquids must be operated
with extreme caution. If liquid comes in contact with internal electrical components or wires, fire or
electrical shock may occur. Adequate surrounding workspace should be provided during use. Do not
operate electrical instrumentation in a combustible atmosphere.
Work surface – Keep well lighted. Be certain the work surface is clean, level and sturdy enough to
support the weight of the unit, particularly if it is to be filled with liquid.
Wear proper apparel – Do not wear loose clothing, neckties or jewelry that might get caught in moving
parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.
Wear safety goggles – Wear safety goggles at all times. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.
Don’t overreach – Keep proper footing and balance at all times.
Maintain instrument with care – Keep screws tight and unit clean. Check periodically for worn or
damaged parts. Inspect the plug and cord before each use. Do not operate this instrument if there are
signs of damage.
Avoid accidental start up – Always make sure the switch is in the "OFF” position before plugging
instrument into outlet.
Disconnect Instrument – Always disconnect the instrument from the power source before servicing.
Do not block cooling vents if provided.
Do not operate this equipment in any manner not specified in this manual.
It is recommended that a fire extinguisher always be located in areas where electrical instruments
are being used.

Specific Safety Considerations
WARNING! IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK. IN THE EVENT OF A
SHORT CIRCUIT, GROUNDING REDUCES THE RISK OF SHOCK. THIS INSTRUMENT MUST BE
GROUNDED.
AVERTISSEMENT : UNE MISE À LA TERRE INADÉQUATE PEUT ENTRAÎNER UN RISQUE DE CHOC
ÉLECTRIQUE. EN CAS DE COURT CIRCUIT ÉLECTRIQUE, LA MISE À LA TERRE RÉDUIRA LE RISQUE
DE CHOC ÉLECTRIQUE. L'ÉQUIPEMENT DOIT ÊTRE RELIÉ À LA TERRE.
This instrument is equipped with a cord having a grounding wire and an appropriate grounding plug.
The plug must be used with an outlet that has been installed and grounded in accordance with all
local codes and ordinances. The outlet must have the same configuration as the plug. DO NOT USE
AN ADAPTER.
Do not modify the line cord that has been provided. If it does not fit the available outlet, contact your
nearest DWK Life Sciences distributor for the proper line cord for your geographic area.
