  • Page 2: Safety Precautions

    Safety Precautions To gain full advantage of the chiller's functions and to avoid malfunction due to mishandling, we recommend that you read this instruction manual carefully before use. This chiller is classified under "appliances not accessible to the general public". The precautions described herein are classified as WARNING and CAUTION.
  • Page 3 amount of any leaked refrigerant does not exceed the concentration limit in the event of a leakage. Otherwise, this may lead to an accident due to oxygen depletion. Contact professional personnel about attachment of accessories and be sure to use only accessories specified by the manufacturer.
  • Page 4 ! CAUTION Do not use the chiller for purposes other than those for which it is intended. Do not use the chiller for cooling precision instruments, food, plants, animals or works of art as this may adversely affect the performance, quality and/or longevity of the object concerned. Do not remove the chiller's fan guard.
  • Page 5 Do not remove the front panel. Touching certain internal parts will cause electric shocks and damage to the unit. Please consult your dealer about checking and adjustment of internal parts. Do not leave the control panel wherever there is a risk of wetting. If water gets into the remote controller there is a risk of electrical leakage and damage to electronic components.
  • Page 6 are opened or closed when they shouldn't be, water may leak and in worse cases, the equipment may catch fire or explode.
  • Page 7 Refrigerant 1. The refrigerant R410A used by the RHAG/RCAG***HA series units from Midea is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. The operating pressure is about 1.6 times higher than the common R22. The new refrigerant R410A consists of two quasi azeotropic mixtures, R32 and R125, each of which accounts for 50%.

  • Page 24: Installation Space Requirements

    4.4 Installation Space Requirements The unit requires enough fresh air for heat exchange through the air side heat exchanger; therefore, be sure to reserve sufficient space around and between units. To enable maintenance and repairs, do not store materials around the unit. Note the following points when installing the unit in areas affected by snow.
  • Page 25 Incorrect installation In monsoon regions where the air heat exchanger faces the monsoon, air flow is like the broken line in the following figure because the air speed is higher than the air inlet speed of the fan. In this case, air that has undergone heat exchange will undergo it again in another heat exchanger, reducing cooling capacity and possibly causing a fault.
