The following questions shall help to recognize possible dangers and to
reduce the risks to a minimum.
• Are all tubes and electrical cables connected and installed?
Note:
sharp edges, hot surfaces in operation, moving machine parts, etc.
• Do dangerous steams or gases arise when heating?
Is an exhaust needed when working?
• What to do when a dangerous substance was spilled on or in the unit?
Before starting to work, obtain information concerning the substance
and determine the method of decontamination.
3.3. Tubing
• Recommended tubing:
Temperature range
CR
®
tubing
Viton tubing
-20 °C ... 120 °C
-50 °C ... 200 °C
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.
