Warning:

Be sure to use specifi ed wires for connections and ensure no external force is imparted to terminal connections. If connections are not fi xed fi rmly,

heating or fi re may result.

Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.

Caution:

Some installation sites may require attachment of an earth leakage breaker for the inverter. If no earth leakage breaker is installed, there is a danger of

electric shock.

This equipment complies with IEC 61000-3-12 provided that the short-circuit power S

12.1. The following phenomena do not represent faults.

Phenomenon Display of remote controller Cause

Indoor unit does not perform cooling

(heating) operation.

“Cooling (heating)” fl ashes When another indoor unit is performing the heating (cooling) operation, the

cooling (heating) operation is not performed.

The auto vane rotates and begins to blow air

horizontally.

Normal display If air has been blowing downward for 1 hour during cooling, the unit may

automatically change to horizontal blowing with the control operation of the

auto vane. During defrosting or immediately after heating start-up/shut-down,

the auto vane automatically rotates to blow air horizontally for a short period

of time.

Fan setting changes during heating. Normal display Ultra-low speed operation is commenced at thermostat OFF.

temperature becomes 35°C, low speed operation for 2 minutes thereafter, and

then set notch is commenced (Hot adjust control).

Indoor unit remote controller shows “H0”

or “PLEASE WAIT” indicator for about fi ve

minutes when turning ON universal power

supply.

“H0” or “PLEASE WAIT” fl ashes The system is being started up.

Operate remote controller again after “H0” or “PLEASE WAIT” disappears.

Drain pump does not stop when unit is

stopped.

Light out After cooling operation stops, the unit continues to operate drain pump for

three minutes and then stops it.

Drain pump continues to operate while unit

has been stopped.

Unit continues to operate drain pump if drainage is generated, even after the

unit has been stopped.

1. Use dedicated power supplies for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.

2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.

3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter.

Make sure the power-supply voltage does not drop more than 10%.

4. Specifi c wiring requirements should adhere to the wiring regulations of the region.

5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed fl exible cord (design 245 IEC57).

6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air Conditioner installer.
