Prepare pump operation:/准备泵操作 - Close valve pos.9. 关闭9号阀。 - Connect the pump motor and run the motor instantaneously to check for correct direction of rotation. The motor should run in the direction indicated with the arrow on the pump. If the direction is reversed, exchange any two wires of the three phase power wires. This operation should only be carried out by authorized personal. 将泵电机接线接好，并尝试接通电源，检测泵的旋转方向是否正确。泵的旋转方向应 当与箭头指示一致。如不一致，应当由电气工程师对换三相电线中的任意两根的位 置。
- Open each of the bleeding valves in the system until all air is removed. 在系统中空气排尽以前不可关闭排气阀。
- When all air is removed leave bleeding valves closed. 在系统中空气排尽后必须关闭排气阀
Filling device:/加液装置 - Before applying coolant to the system, place the filling device in a high position (higher than the highest point in the system). 在系统加液之前，请将加液装置置于较高位置。（高于水泵系统的最高位置）

Installation 安装
Mounting of the LCU/冷却系统的安装
1. Mount the frame of the unit safely supported./将冷却系统安全的固定在支架上。 2. Connect the hoses according to the “Diagram for component placement” and make sure they are safely fastened./根据《零配件装配图》将管路接好，并确保接口已经接牢。 3. Connect transmitters to the control unit. Use the datasheet for each transmitter for correct connection./将传感器接入控制单元。请严格按照要求将传感器接好. 4. Prepare the wiring to the pump motor according to the datasheet./根据说明书的要求准备好连接泵电 机的电线。
Wiring/线路
1. Use an electromagnetic switch that conforms to specification (voltage, capacity, etc.) of the pump motor./仅允许使用符合泵电机技术要求的电磁开关。
2. Electromagnetic switch and push button switch should be firmly installed at the place reasonably distant from the pump./电磁开关和按钮与泵应当保持合理的距离。
Expansion tank:/膨胀水箱 - Check that the pre-charge pressure in the expansion tank is 0,5 bar at 20°C. 检查膨胀水箱的初始压力是否为在20°C时为0 .5 bar。 - Measure the pressure at the valve under the top cap of the tank. 检测膨胀水箱顶部保护盖下面的阀的压力。
- Tighten the air vent screw when the pump has been completely filled with coolant. 在系统中空气排尽后，拧紧螺丝。
Base pressure:/基本压力
- Start motor and apply coolant to the system with pump pos. 1. 开启电机通过1号泵向系统内加液 - When the base pressure on the pressure gauge pos. 14 is 2bar, shut off valve pos. 12. 当14号压力显示器显示压力为2bar 时，关闭位于12号阀门。
- The 3-way valve pos. 8 can be operated manually when the gearbox is switched off as shown below. 位置8的三向阀可以手动调节,如果阀体内的齿轮箱如图一一样关闭.
- The 3-way valve pos. 8 is adjusted to middle position. 位置8的三向阀调节到中间位置,如图二
- Stop the pump. 关闭泵
Bleeding the system, phase 2:/系统排气第二步 - Wait until the air vent valve pos. 18 is closed (no noise of leaking air). 观察18号排气阀直到其关闭（即没有排气的声音） - Open valve pos. 9. 打开位于9号阀。 - Run the pump for 2 sec. 运行泵2秒钟 - Wait until the air vent valve pos. 18 is closed (no noise of leaking air). 观察18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。
- The cap can easily be removed with a screw driver. 该保护盖可以用螺丝刀轻松取出。
- If pressure is to low, then charge gas (Nitrogen) until 0,5 bar is reached. 如果压力过低，请充入氮气，直至达到0.5bar。

Precautions on operation/操作提示
Never operate the LCU pump dry or with the suction valve closed, except for the application of coolant, see chapter “Applying coolant to the system”. Otherwise the pump will be damaged. Check the direction of pump rotation indicated on the motor and pump. 本系统严禁在无水状态下工作！也禁止在泵的进口阀关闭的情况下工作（除非是为了加液）。具 体请查阅《冷却系统加液指导》。否则泵将会损坏。注意泵的转向必须与电机与泵外壳的标识一 致！
Electrical connections./电路接法 The electrical connections should be carried out by an authorized electrician in accordance with local regulations. We are not responsible for any accidents which are caused by non observance of this instruction. 仅允许获得授权的专业电气工程师进行电路连接作业。由于违反此规定而引起的任何事故，我们 将不承担任何责任。
- If the base pressure is 2bar 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2bar，则说明系统已经加液完成，可以 运行。
Base pressure adjustment:/基本压力调整 - If base pressure is lower than 2bar after removing all the air, please adjust as follows: 如果系统基本压力在排尽空气后仍然低于2bar,请按照下面的步骤来调节： - Close valve pos. 9. 关闭9号阀。 - Open valve pos. 12. 打开12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
Connection of external coolant tank:/外部冷却液容器接法
- Connected coolant tank to valve pos. 12 (Closed position). 将外部冷却液容器接到位于12号阀。（阀门必须关闭）
Open valves:/打开阀门 - Open all valves in the system: LCU pos. 2, 5, 9, 13, 19, 21 and valves in the generator, except bleeding valves. 打开系统中所有的阀门:冷却系统的2, 5, 9, 13, 19, 21位置和发电机端的阀门，除了排 气阀.
- Tighten the air vent screw when the pump has been completely filled with coolant. 在系统中空气排尽后，拧紧螺丝。
