5.7 Distillation outlet tube
Fit the distillate outlet tube onto the cooler outlet using the
coupling ring and inserted gasket. Slide the PTFE hose,
top down, as far to the bottom of the receiving vessel as
possible.
The distillate outlet tube has an aeration valve (patented
by Büchi) that keeps the receiving solution from being
sucked back.

Before switching the distillation machine K-314 on for the
first time, make certain that the power system voltage is
the same as that indicated on the unit's nameplate.
Then connect the distillation unit cable to the mains.
5.9 Adjusting the cooling water flow
• Open the cooling water tap until the flow of water at the
outlet hose is 1 l/min.
The distillate must leave the cooler cooled!.
