The following subjects are recommended that be taken once every 3 to 6 months, the actual interval base on the load and ambient condition.
1. Check the bearing whether it has worn out or there is phenomena of lube leak.
2. Check the tightness of bolts of the bearing.
3. Check the tension of belt. It should be regulated if the belt skidding or replaced if it has worn out.
以下维护项目建议每年进行一次。
1).检查电气接线情况。
2).检查机壳有无破裂及腐蚀现象，如有，应清理并油漆。
3).检查所有维修门的密封是否良好，开关是否灵活。
皮带张力：
皮带应维持正确的张力，以避免轴承提早报废和不必要的皮带磨损。皮带张力检查可利用皮带张力检查器。(如图四)
皮带维护：
以干布清洁皮带表面，皮带表面不可沾有任何油脂。更换皮带时，应使用同型的新皮带，并正确安装皮带。并校准皮带轮，确保皮带轮基准面在同一平面上。（如图五）
The following subjects are recommended that be taken once every one year.
1. Check the connection of the wiring.
2. Check the panel whether it has crack or rust, repaint it if the answer is yes.
3. Check the sealing of maintenance door, and the flexibility while it open and closed.

Tension of the belt
The tension of the belt should be at a accurate degree to avoid accidental damage. You should use a professional equipment to check the tension of the belt. (See figure 4)
Maintenance of belt
Clean the surface of the belt with dry clothes, keep the surface out of any oil. Replace the belt with a same type, and then regulate the pulley to insure the two pulleys are in the same plane. (See figure 5)

盘管维护：
1).定期检查盘管的清洁度。
2).以正常气流的相反方向喷射压缩空气、蒸汽或水即可有效清洗盘管。如盘管十分肮脏，应使用清洁剂清洗。机组运行两年后应用化学方法清除换热器水管内的水垢。
过滤网维护：
开始启用本机组时，由于系统风管内灰尘较多，很快就会堵塞滤网，因此，运行8小时后，应进行清洗。以后每月清洗一次。
Coil maintenance
1. Clean coil termly.
2. Coil would be cleaned efficiently by spray compress air, steam or water over it. If it too much dirty, cleanser is recommended. We also suggest that you clean out fur in the tubes with chemical medicine ever two years operation.
Filter maintenance
第8页/共10页
The filters will be blocked up soon after installation because too much dirty in the duct. So a cleaning is recommended after the first 8 hours operation, and then take once every month.
