Installing Evaporator (Chiller)

NOTE: NOTIFICATION 
Opened refrigerant system for repairs. 
  • Risk of moisture getting into the refrigerant system. 
  • Risk of contaminating the refrigerant circuit. 
  • Risk of saturation and irreparable damage to desiccator. 
  • Irreparable damage to the desiccator can damage the compressor and evaporator. 

    → After opening the refrigerant circuit, close off the refrigerant lines/connections immediately using the relevant stoppers. To avoid contaminating the refrigerant circuit, the stoppers for the different refrigerants must be stored and used separately.

    → The desiccator must be replaced if the air humidity is high and if the refrigerant circuit is left open for a long time.
