Warning: Tubing:
At high working temperatures the tubing used for temperature application and cooling
water supply represents a danger source.
A damaged tubing line may cause hot bath fluid to be pumped out within a short time.
This may result in:
• Burning of skin
• Difficulties in breathing due to hot atmosphere
