9. Safety recommendations
Follow the safety recommendations to prevent damage to persons or property. Further,
the valid safety instructions for working places must be followed.
• Connect the unit only to a grounded mains power socket!
• Observe the fire point of the bath medium used.
The excess temperature protection should be set at least 20 °C below the fire point.
• Pay attention to the thermal expansion of bath oil during heating to avoid overflowing
of the liquid.
• Prevent water from penetrating into the hot bath oil.
• 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.
• Exercise caution when emptying hot bath liquids!
• Observe the limited working temperature range when using plastic bath tanks.
• Employ suitable connecting tubing.
• Make sure that the tubes are securely attached.
• Avoid sharp bends in the tubing, and maintain a sufficient distance from surrounding
walls.
• Regularly check the tubing for material defects (e.g. for cracks).
• Before cleaning the unit, disconnect the power plug from the mains socket.
