Electrical Precautions

| Take the following precautions to reduce the risk of electric shock, fire, or explosion resulting in serious injury or death:
---|---

• Only use electrical protection equipment and tools suited for this installation.

• Insulate the infrared (IR) receiver kit against moisture and temperature extremes.

• Communication cabling shall be a minimum of AWG18 (0.82mm 2), 2-Conductor, Stranded Copper. The shielded cable must be considered for applications and routing in areas of high EMI and other sources of potentially excessive electrical noise to reduce the potential for communication errors. When shielded cabling is applied, proper bonding and termination of the cable shield are required as per Johnson Controls-Hitachi Air Conditioning guidelines. Plenum and riser ratings for communication cables must be considered per application and local code requirements.

• The polarity of the input terminals is important, so be sure to match the polarity when using contacts that have polarity.

• Highly dangerous electrical voltages may be 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.

• Before installing the infrared (IR) receiver kit, ensure that the indoor and outdoor unit operation has indoor or outdoor units. Otherwise, water leakage or electrical breakdown may result.

• Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the main power supply. Before connecting or servicing the controller or cables to indoor or outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected. Check with a meter and equipment.

• Use an exclusive power supply at the controller’s rated voltage.

• Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit

• Clamp electrical wires securely with a cord 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.

• Make sure that the terminals do not come into contact with the surface of the electrical box.
  If the terminals are too close to the surface, it may lead to failures at the terminal connection.

• Do not clean with, or pour water into, the infrared (IR) receiver kit as it could cause electric shock and/ or damage the unit. Do not use strong detergent such as a solvent. Clean with a soft cloth.

• Check that the ground wire is securely connected. Do not connect ground wiring to gas piping, water piping, lighting conductor, or telephone ground wiring.

NOTICE

• C4IRK01 is only available to be used in combination with the wireless controller CIRO1 and the indoor unit 4-way cassette type models.

Identifying Indoor Units Installed for a Side-by-Side Operation

WARNING
Turn OFF the power supply completely before setting the DIP switch for the IR receiver kit.
Not doing so may cause an electric shock.
When two indoor units are installed side by side, the commands from the wireless controller may be received by both indoor units. The function, “Identifying of Indoor Units Installed Side by Side” enables the operation of the individual unit correctly without interfering with the right, the indoor units of A and B are set side by side. In this instance, unit B is set as “Identifying Indoor Units Installed Side by Side”.
The setting of Identifying of Indoor Units Installed Side by Side

1. IR Receiver Kit Setting
2. Wireless Controller
   Set the wireless controller according to the Installation and Maintenance Manual for the Wireless Controller.

Cancellation of Identifying of Indoor Units Installed Side by Side

1. IR Receiver Kit Setting
   Set the Number 2 pin of the IR receiver kit DIP switch (DSW1) “OFF” side for cancellation.

2. Wireless Controller
   Cancel the wireless controller setting according to the Installation and Maintenance Manual for the Wireless Controller.

Simultaneous Operation

Up to 16 indoor units can be simultaneously controlled using one wireless controller.
When multiple indoor units are installed in a large room, all the indoor units can be controlled to start/ stop with only one wireless controller.
NOTE:
Do not apply a simultaneous operation for indoor units installed separately in different rooms.
Some units may be left without turning OFF the power supply.
Installation of IR Receiver Kit
In an instance of simultaneous operation of multiple (up to 16 ) indoor units by the wireless controller, install the IR receiver kit only to the unit to be operated. Other units should be standard units without the IR receiver kit. If multiple IR receiver kits are required to be installed, two IR receiver kits are the maximum.

Electrical Wiring Connecting and Setting

1. The connection between Indoor Units
   Perform the connection work as shown below.
   Power Supply Cable 208/230V

• For twin, triple or quad combinations, a communication cable for the wireless controller is not required.
  Use the field-supplied communication cable (AWG18) for the wired controller cable. The total length should be 1640ft (500m). If the total length is less than 98ft (30m), AWG22 cables can be used.

  2. Do not run the connected wireless controller cable and the power supply cable (208/230V) in parallel in the indoor units.
     Stabilize the cable with cable bands. Along with the wiring outside the indoor units, the control cables should not run with the power supply cable (208/230V). Keep a separation of more than 12 inches, or run the cable through a grounded metal conduit.

  3. Unit Number Setting
     The indoor unit numbers are set by the auto-address function. Therefore, an indoor unit number setting is not required. If the indoor unit number is fixed, set the unit number of all indoor units respectively and serially. It is recommended that the unit number settings begin with “1”. The setting is set not to overlap the unit number.
     Unit Number Setting

Test Run for Wireless Controller (CIR01)

After all, installations are completed, a test run should be performed.

1. Perform the test run according to the installation manual for the wireless controller.
2. The test run for the wireless controller will take two hours to complete. If the TIMER indicator (green) is flashing (0.5 seconds ON/0.5 second OFF) after two hours, an alarm may occur. Operate the indoor unit and check for abnormalities.

Alarm Indication

NOTICE

• If a malfunction occurs, such as a safety device actuation, during the test run or the normal operation, “RUN” (red light) flashes (0.5 seconds ON/0.5 second OFF).

• The alarm codes are indicated by the flashing of “DEF” (green light) and “FILTER” (yellow light).
  The first LED light is green. The number of times this LED flashes (0.5 seconds ON and OFF) will tell you the “DEF” Alarm Code.
  The second LED light is yellow. The number of times this LED flashes (0.5 seconds ON and OFF) will tell you the “FILTER” Alarm Code. < Example >
  These signals are repeated until the alarm is reset.

• “RUN” (red light) flashing (1 second ON/1 second OFF) indicates an abnormal transmission (connector loss, connector disconnection, broken wire or incorrect wiring, or something similar) between the indoor unit and the IR receiver kit.

• When the IR receiver kit is connected to multiple indoor units, the alarm code is indicated for each indoor unit in order.

Alarm Code Table
Further details for alarm codes can be found in the “Installation and Maintenance Manual” for the indoor unit.
