• Set the excess temperature safety installation at least 25 °C below
the fire point of the bath fluid.
• Observe the limited working temperature range when using
plastic bath tanks.
• Never operate the unit without bath fluid in the bath.
• Pay attention to the thermal expansion of bath oil during heating to
avoid overflowing of the fluid.
• Prevent water from entering the hot bath oil.
• Do not drain the bath fluid while it is hot!
Check the temperature of the bath fluid prior to draining (e.g., by
switching the unit on for a short moment).
• Use suitable connecting tubing.
• Avoid sharp bends in the tubing, and maintain a sufficient distance
from surrounding walls.
• Make sure that the tubing is securely attached.
• Regularly check the tubing for material defects (e.g., for cracks).

• Observe all warning labels.
• Never remove warning labels.
• Never operate units with damaged mains power cables.
• Repairs are to be carried out only by qualified service personnel.
• Some parts of the bath cover and the pump connections may become
extremely warm during continuous operation. Therefore, exercise
particular caution when touching these parts.
Notice: Check the safety installations at least twice a year!
• Excess temperature protection according to IEC 61010-2-010.
With a screwdriver turn back the adjustable excess temperature
protection until the shut-down point (actual temperature).
