appropriate training before you put the unit in service.
Note: Use the unit only in the way described in this manual. Failure to follow the guidelines and
instructions in this manual may be dangerous and illegal.
General Safety Considerations
Your water bath and its recommended accessories have been designed and tested to meet strict safety
requirements.
For continued safe operation of your water bath, always follow basic safety precautions including:
Read this entire manual before using the water bath.
Be sure you follow any city, county, or other ordinances in your area regarding the use of this unit.
Use only approved accessories. Do not modify system components. Any alterations or modifications
to your water bath may be dangerous and will void your warranty.
Always plug the unit’s power cord into a grounded electrical outlet that conforms to national and local
electrical codes. If the unit is not grounded, parts such as knobs and controls may conduct electricity
and cause serious injury.
Do not connect the unit to a power source of any other voltage or frequency beyond the range stated
on the power rating overlay at the rear of the unit.
Do not modify the power cord provided with the unit. If the plug does not fit an outlet, have a proper
outlet installed by a qualified electrician.
Avoid damaging the power cord. Do not bend it excessively, step on it, place heavy objects on it. A
damaged cord can easily become a shock or fire hazard. Never use a power cord after it has become
damaged.
Do not position equipment in a manner that prohibits access to power cord.
