    13. INSTALLATION WR2-Series-575V 13-3. Piping direction 1. Insulation installation With City Multi WY/ WR2 Series piping, as long as the temperature range of the inlet water is kept to average temperatures year-round (30°C[86°F] in the summer, 20°C[68°F] in the winter), there is no need to insulate or otherwise protect indoor piping from exposure.

Arrange to have an expert install the system correctly. 1-1. General precautions 1-1-1. Usage The air-conditioning system described in this DATA BOOK is designed for human comfort. This product is not designed to assist in the preservation of food, provide conditions to maintain plants or animals, or stabilize environments for the preservation of precision equipment or art objects.
  • Page 135 Ensure that there is enough space around each unit. 1-1-7. Optional accessories Only use accessories recommended by Mitsubishi Electric. Consult your local distributor or a qualified technician when installing them. Improper installation by an unqualified person may result in water leakage, power leakage, system breakdown, or fire.
  • Page 136 1. Installation information Installation information 1-2. Precautions for Indoor unit and BC controller 1-2-1. Operating environment The refrigerant (R410A) used in the air conditioner is non-toxic and nonflammable. However, if the refrigerant leaks, the oxygen level may drop to harmful levels. If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration from exceeding the safety limit even if the refrigerant leaks.
  • Page 137 1. Installation information Installation information 1-3. Precautions for outdoor unit/heat source unit 1-3-1. Installation environment The outdoor unit with the salt-resistant specification is recommended for use in an area in which it will be exposed to salt air. Even when the unit with the salt-resistant specification is used, it is not completely protected against corrosion. Be sure to follow the directions or precautions described in the Instruction Book and Installation Manual for installation and maintenance.
