SAFETY PRECAUTIONS

  • Before starting the installation, read the “Safety Precautions” described below.
  • The following precautions must be observed as they describe serious safety matters.
  • The safety precautions are described with the degree of danger.
    Warning icon WARNING When you handle it wrong, it can lead to death or serious injury.
    CAUTION When you handle it wrong, it can lead to injury or damage to buildings and furniture.
  • After installation, make test operation and confirm that it works properly, and explain the safety precautions, operation method, and maintenance to your customers.
    Tell your customers to keep this installation ion manual together with the operation manual with them, and when they give or sell this machine to other person put this installation manual and operation manual with it.

WARNING
The installation must be done by dealer or qualified person.

  • If the customers do the installation by themselves and it is not perfectly installed it can cause a water leak, electric shock, or fire.
    The installation must be done in accordance with this manual.
  • If the installation is not perfectly done, it can cause a water leak, electric shocks, or fire.
    Never try any modification.
  • For repair, ask your dealer. If the machine is not modified or repaired completely, it can cause water leaks, electric shock, or fire. Never move or reinstall the machine by the customers.
  • If the installation is not perfectly done, it can cause water leaks, electric shocks, or fire. Ask your dealer or qualified person.
    The wiring must be securely done by using the proper cable. The wires should be connected to the terminals not to have the external force of the cable.
  • Faulty connections can cause heat or fire. The terminal cover (panel) of the unit must be installed securely.
  • Faulty installation can cause fire or electric shock by dust or water. The electric installation must be done by a qualified person in accordance with this installation manual. Use the separate circuit only for this machine and use rated voltage and circuit breaker.
  • If the electric circuit power is not sufficient or the wiring is not properly done, it can cause electric shock or fire.

Before electric wiring
CAUTION
Install a circuit breaker depending upon the location.

  • Without a circuit breaker, it can cause electric shock. Use standard wires which meet current capacity.
  • Otherwise, it can cause short-circuit, heat, or fire. Wires must not have tension.
  • It can cause snipping, heat, or fire.
    Put ground wire.
  • Never ground to gas pipe, water pipe, lightning conductor, or telephone ground wire. The faulty ground can cause short-circuit.
    Use proper fuses
  • If you use larger size fuses or needle wire, it can cause failure or fire.

Before test operation
CAUTION

Turn the power on 12 hours or more before operation.

  • If you start an operation as soon as the power is on, it can cause failure. Never turn the power off during the season. Never operate the machine without the panel or guard off.
  • It can cause serious injury being caught by a rotating part or burn or electric shock by high voltage part. Never operate the machine without air filter off.
  • It can cause failure by dust.
    Never operate the switches with your hand wet.
  • It can cause electric shock. Never touch refrigerant pipes while the machine running.
  • The refrigerant pipes become high and low temperature while the machine running. If you touch the pipes by hand, it can cause chilblain or burn. Never turn the power off as soon as the machine stops.
  • Wait for 5 minutes or more. It can cause water leaks or failure.

CAUTION
Attention to M-NET connection
Pay attention to the next points for the wiring of shielded wires.
The shielded wires of M-NET transmission should be connected with the ground wire at any only one place of the unit to be connected.

  • It can cause transmission errors due to noise. Centralized control remote controller reads “0403” “6607” error

  1. Refer to the appendix List of Models to check the applicable models.
  2. In case the outdoor unit is grounded, connect the ground wire supplied as an accessory to the S terminal (secondary) of the M-NET terminal block and the M-NET Ground terminal inside of the electric box with using the screws supplied.
  3. If the shield and earth are grounded ithe n two or more locations, the electrical circuit is generated through them, and a potential difference is created because of the impedance difference between or among the ground locations. This may cause noise in the shield. The ground at only one point, then no circuit is created and no noise gets in.

Wiring method for M-NET

Caution for wiring

  1. Never supply voltage 208V-230VAC to the terminals for M-NET transmission. If the voltage is supplied, it can break the electronic parts on the M-NET board.
  2. Use the shielded cable (CVVS, CPEVS, MVVS) of 1.25mm² (AWG 16) with 2 wires (polarity is not a concern) for the transmission cable. Never use transmit wires of different systems with a cable that contains multi wires. The communication of transmitting signals will not work properly and it can cause the wrong operation. w1
  3. The power consumption coefficient of the M-NET board is “1”.
    *1 “Power consumption coefficient” is a coefficient to calculate the relative power consumption of the devices that receive power through the M-NET transmission cable.

Switch setting

Before installation
Set the M-NET address on the M-NET board in advance before installing on the electrical box.

  1. M-NET head address setting
    The setting should be done by rotary switches SW11 and SW12 on the M-NET board. (Factory settings are all Zero) Make sure to set the M-NET address within the range of 01 to 50. When installing two or more outdoor units, do not use the same number more than once for the M-NET address.
  2. Indoor unit connection switch setting
    Set each indoor unit to ON or OFF with SW1.
    M-NET address setting Starting with the M-NET head address set with SW11 and SW12 (Ex 01), the M-NET address is automatically allocated in numerical order to each indoor unit that is connected (Ex 02, 03, 04, 05, 06).

An example of an M-NET address setting

Note
M-NET address should be set within the range of 01 to 50.
For instance, when the head address set with SW11 and SW12 is [47] and you are to connect 5 indoor units A, B, C, D, E, the addresses for each indoor unit are A[47], B[48], C[49], D[50] and E[51]. Since the number for E exceeds 50, this setting is not available.
