5 .5 Tube connections
5 .5 .1 Cooling water
When connecting the white cooling water tubes (silicon), consider the following:
• Use GL-14 tube clips.
• 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 and/or reduce the temperature of the coolant, a recirculating chiller like the
F-100/F-108 is recommended.
• Check the tubes from time to time and replace them if they become brittle.

NOTE
It is important to connect the coolant with the secondary condenser first and then with the primary
condenser as the temperature rise in the coolant primarily takes place in the latter.
When the type C condenser is used no tube connections for cooling are required.
