    Safety Precautions ■ Symbol description ◆ Dear user, For the better understanding of this Manual and the proper operation of the chiller, the marks and symbols used in this Manual are described as follows: WARNING: it is likely to cause death, serious injury and other severe accidents if the user fails to do as required.
  • Page 5 The installation location of the equipment should ensure that the drainage system is unblocked. Improper drainage systems may cause poor drainage and cause equipment to get wet. The unit must be warmed up for two hours for the first time. This is to protect the compressor. If the preheating time is not met, the unit may report the oil preheating and the temperature barrier.
  • Page 6 CAUTION No unit is allowed to be installed near such places that are dirty, oily, salty, exposed to a large amount of sulfur gas and where the unit parts may be subjected to corrosion, such as toilet vent, operation room vent and sewage treatment equipment.
