When connecting the cooling water tubes

• The tubes used must all have the same inner
diameter (approximately 6 mm).
• For safety reasons, secure the tubes with
commercial tube pivoting clamps or cable
binders.
• To save cooling water, you can use the Distil-
lation Chiller F-1xx.
• Check the tubes from time to time and
replace them when they are brittle.
