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.
