Johnson Controls distributors similarly are only authorized to provide refrigerants that have been approved for use in the countries or markets they serve. The refrigerant used in this unit is identified on the unit’s faceplate and/or in the associated manuals.
  • Page 9 ● Clamp electrical wires securely with a cable clamp 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.

    2) Limits on Outdoor Air Intake • Do NOT ingest air from the outdoors directly into the indoor unit. If an outdoor fresh air intake is necessary for air-conditioning, Johnson Controls Inc. recommends the installation of the ERV (Energy Recovery Ventilation) (Field-supplied) system.

  • Page 16: Setting The External Pressure

    ● If a lower sound level is required, install field-supplied silencer. ● The facility design should be “Unit External Static Pressure = Duct Pressure Loss + Suction / Discharge Pressure Loss”. If duct pressure loss fall below the external static pressure, airspeed will increase and noise levels along with it. Also, water may splash out from unit and the motor protection circuit activated. Problems such as the inability to adjust airspeed can occur if the external unit static pressure fall below the duct pressure loss. Adjust the airflow control damper or shift the static pressure control switch to an equal level between the external static pressure and duct pressure loss. (refer to “Setting the External Pressure” section for the details.) ● Basically, this unit is configured to install the ducts on the inlet side and the outlet side. Ask for more information on using return ducts in the ceiling.

  • Page 17: Refrigerant Piping Work

    Refrigerant Piping Work Use the specified non-flammable refrigerant (HFC R410A) for the outdoor unit refrigerant cycle. Do not charge the unit with anything other than HFC R410A, such as hydrocarbon refrigerants (propane and Isobutene), oxygen, and other flammable gases (acetylene, ammonia, and so forth), or any poisonous gases when installing, maintaining and moving the unit. These substances are volatile and dangerous and can result in fire, explosion, and serious or fatal injuries. 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) Tolerances for refrigerant piping lengths depend on the combination with the outdoor unit. Refer to the “Installation and Maintenance Manual”...

  • Page 19 (6) Wherever buried piping exists on site, make sure there is a service doorway to provide adequate access to inspect piping sockets and elbows, and for interconnecting parts. (7) Piping must be reinforced to withstand earthquakes so as not to be damaged by an external force. (8) Do not tightly secure refrigerant piping to accommodate expansion and contraction.

  • Page 20: Drain Piping

    Drain Piping Perform drain piping work and attach the insulation before attempting any refrigerant piping work. (1) Figure 7.1 shows all drain piping connections. (2) Prepare a polyvinyl chloride piping with 1-1/4 inches (32mm) outer diameter. (3) Fasten the tube to the drain hose with the adhesive agent and the field-supplied clamp. The drain piping must be performed with a DOWN-SLOPE pitch of 1/25 to 1/100.

  • Page 22: Electrical Wiring

    Electrical Wiring ● All electrical work must be done as outlined in this manual and in accordance with this manual. Substandard work can result in fire and damage to the unit. ● Use specified cables between units and choose the cables correctly. If not, an electrical shock or fire may occur. ● Do not open the service cover or access panel for the indoor or outdoor units without turning OFF the main power supply. It can result in an electrical shock. ● Turn OFF the main power switch of the indoor unit and the outdoor unit before attempting any electrical wiring work or a periodical check is performed. If not, it will result in an electric shock or a fire. ● Check to ensure that the indoor fan and the outdoor fan have stopped before attempting any electrical wiring work or for any scheduled electrical work that is being performed. ● Tighten screws according to the following torque. M3.5: 0.9 ft·lbs (1.2 N·m) M4: 0.7 to 1.0 ft·lbs (1.0 to 1.3 N·m) ● Secure all cables together with zip-ties and seal the connecting hole against the onslaught of moisture and insects. ● Run the electrical wiring through the connecting hole in the side cover when using conduit. ● Secure the wired controller cable using the cable clamp inside the electrical box. General Check (1) Make sure that the field-selected electrical components: (main power switches, circuit breakers, wires, conduit connectors, and wire terminals) have been properly labeled in accordance with electrical data as specified in the Engineering Manual.
