- Wait until the air vent valve pos. 7 is closed (no noise of leaking air).
观察7号排气阀直到其关闭（即没有排气的声音）
- Repeat the 2 last steps (6-10 times) until all air is removed from the system.
重复以上步骤直到系统内的空气被排尽。

- If the base pressure is 1,5 bar after removing all the air, the system is ready torun.
如果在系统中空气排尽后显示压力为1.5bar，则说明系统已经加液完成，可以
运行。

Base pressure adjustment:/基本压力调整

follows:
如果系统基本压力在排尽空气后仍然低于1.5bar,请按照下面的步骤来调节：

关闭11号阀。

- Open valve pos. 10.
打开10号阀。

- Bleed the pump by loosen the air vent screw in the pump head.
拧开泵前部的螺丝以排出系统中的空气
