  • Page 5: Introduction

    Introduction Read following sections carefully before installing this product. Read over the "Installation and Maintenance Manual" for the outdoor unit as well. Forward this information, and the warranty to all installers and users. Ask end users to maintain copies for future reference. (Refrigerant Piping Work) (Electrical Wiring Work) (Ref.
  • Page 6 ● Do not touch or adjust any safety devices inside the indoor or outdoor units. All safety features, disengagement, and interlocks must be in place and functioning correctly before the equipment is put into operation. If these devices are improperly adjusted or tampered with in any way, a serious accident can occur.
  • Page 7 ▫ A room: Properly insulate any refrigerant tubing run inside a room to prevent “sweating” that can cause dripping and water damage to wall and floors. ▫ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit to prevent water damage and abnormal vibration.
  • Page 8 Refrigerant Precautions To reduce the risk of serious injury or death, the following refrigerant precautions must be followed. ● As originally manufactured, this unit contains refrigerant installed by Johnson Controls. Johnson Controls uses only refrigerants that have been approved for use in the unit’s intended home country or market.
  • Page 9 ● Clamp electrical wires securely with a cable band after all wiring is connected to the terminal block. In addition, run wires securely through the wiring access channel. ● When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular intervals, but not too tightly.
  • Page 10 ● Proper handling of this unit requires two-people. Safe handling and installing the indoor unit requires the strength of two people. Mounting the unit alone may cause injury due to fall of the unit. Although the unit may be girded with steel banding, do not use it for transportation. Avoid contact with finned surfaces of the heat exchanger as sharp edges can cause severe injury to hands and fingers.
