14.2 Installation introduction and key points:
1. Water quality requirement: pay attention to the problem of used water, scale and sundries will bring great impact to the normal
operation of the system. At the beginning of the system operation, the filtering net inside the Y-shape filter should be washed from
time to time.
2. When connect pipe (include flexible pipe), please lock module pipe orifice and water pipe joint respectively in order to avoid the
module set water pipe be damaged by large torque, result in water pipe cracking and leakage.
3. In order to improve the efficiency of water system, must proceeding pipeline air exhaust, can install vent valve at the top of
pipeline system.
4.The following is the connection schematic of air cooled scroll chiller water system.
