  • Page 25: Installation And Debugging

    Installation and Debugging Please read this chapter carefully before installation, and you must install the machine according to the following procedures! Before installing the chiller, please design the pipe system reasonably, lay out the position of injection mould machine and cooling water tower to make the repair and maintenance convenient, the installation of chiller should be convenient to operate and keep appropriate distance from cooling water tower.

  • Page 26: Water Pipe Installation

    9) The pipeline diameter of cooling water tower and circulating pump should be no less than that of the connection tube of condenser (the installation of ingress and egress pipeline system should comply with the assembly line diagram). When perform long distance transportation the heavy caliber water pipe should be used for connecting the cooling water.
  • Page 27 inorder to make the water flow rate in each exchanger maintain the same, and to avoid bias current phenomena, try to make the shuttle water pipe resistance from chiller to every heat exchanger all the same. 4) Adopts sealed loop water system to buffer the water volume expansion or shrink phenomina and insulate the backup water pressure to water pipe's impact.
