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. Provide this information and the warranty must be provided 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 Installation Precautions To reduce the risk of serious injury or death, the following installation precautions must be followed. ● When installing the unit into… ◦ A wall: Make sure the wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.
- 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 Electrical Precautions Take the following precautions to reduce the risk of electric shock, fire or explosion resulting in serious injury or death. ● Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death.
- 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.

Page 17: Installation Of Auxiliary Heater (Field-Supplied)
Installation of Auxiliary Heater (Field-Supplied) ● When the auxiliary heater shall be installed and connected, make selection by following local codes, regulations and approved by UL1996, and refer to this manual. Improper installation may result in fire from overheating. ● When the auxiliary heater shall be installed and connected, do not install in places where heater can come into contact with combustible materials. Otherwise, fire may result. ● Provide adequate clearance spacing between the auxiliary heater and indoor unit. Refer to the auxiliary heater manual for details. Otherwise, fire may result from over heating the indoor unit. ● Do not attach the auxiliary heater directly to the indoor unit. Otherwise, fire may result from combustible materials inside the indoor unit. ● Route the auxiliary heater wiring so that it can not come into contact with any part of the heater. Otherwise, fire may result. ● When the auxiliary heater shall be installed and connected, duct material should be a sheet metal or non-flammable material. Otherwise, fire may result. ● Fire may result from debris and dust inside the duct. Indoor unit must be cleaned on a regular basis by following the Service Manual. Also auxiliary heater and duct must be cleaned on a regular basis by following their manuals. ● Auxiliary heater must be properly selected so that double overheating safety protection devices (Thermal Protector and Thermal Fuse) are built-in. Otherwise, fire may result from over heating of heater when the components such as relays fails. P01432Q-rev.1... -

Page 20: Refrigerant Piping Work
6. Refrigerant Piping Work Use the specified non-flammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle. Do not charge the unit with materials other than R410A, such as hydrocarbon refrigerants (propane and isobutan), oxygen, flammable gases (acetylene, ammonia, etc.) or poisonous gases when installing, maintaining and moving the unit. These flammables are extremely dangerous and may cause explosion, a fire, or injury. For details on refrigerant piping work, vacuum pump, and refrigerant charge, refer to the "Installation and Maintenance Manual" for the outdoor unit. Piping Materials (1) The tolerance of refrigerant piping length differs depending on the combination with the outdoor unit. Refer to “Installation and Maintenance Manual”... -
