  • Page 22: Application Data

    FORM QWC3-EG1 (217) Application Data UNIT LOCATION Chillers are designed for indoor installation. Units should be located away from noise-crit- ical areas. Service clearance must be allowed and include space for remov ing condenser tubes. A doorway or window can sometimes provide space for tube removal. Units should be installed indoors where they are not exposed to rain or water splash.
  • Page 23 Quantech liquid chiller units are factory wired for optimum reliability. Therefore the unit controls must not be modified without ex pressed written consent by Quantech. The use of a simple switch or timer from a remote point is permitted; but it must be connected to the unit panel at points expressly indicated for that purpose.
