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 
 
Safety recommendations 
 Employ suitable connecting tubing.
 Make sure that the tubing is 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).
 Preventive maintenance: Replace the tubing from time to time.
