2 About Lead Free Solder (PbF)
2.1. DISTINCTION OF PbF P.C. BOARD
P.C. Boards (manufactured) using lead free solder will have a PbF stamp on the P.C. Board.
2.2. CAUTION
· Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70 °F (30 - 40 °C) higher.
Please use a high temperature solder iron and set it to 700 ± 20 °F (370 ± 10 °C).
· Pb free solder will tend to splash when heated too high (about 1100 °F/ 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb
solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.

9 Operation Details (Functions & Protection)
9.1. Simultaneous Operation Control
1. Operation modes which can be selected using the remote
control unit: Automatic, Cooling, Dry, Heating, Fan operation mode.
2. Types of operations modes which can be performed
simultaneously
· Cooling operation and cooling, Dry or fan operation
· Heating operation and heating operation
3. Types of operation modes which cannot be performed
simultaneously
· While a cooling operation is in progress, a heating operation
cannot be performed by an indoor unit in another room.
In the room where the operation button for cooling was pressed
first, the operation is continued. In the room where the operation
button for heating was pressed afterward, the operation lamp of
the indoor unit blinks, where the attempt is made to establish the
heating operation. Its fan is stopped, and the air does not
discharged.
· While a heating operation is in progress, a cooling operation
cannot be performed by an indoor unit in another room.
In the room where the operation button for heating was pressed
first, operation is continued. In the room where the operation
button for cooling was pressed afterward, the operation lamp of
the indoor unit blinks, where the attempt is made to establish the
cooling operation. Its fan is stopped, and the air does not
discharged.
4. Operation mode priority control
· The operation mode designated first by the indoor unit has
priority.
· If the priority indoor unit stops operation or initiates the fan
operation, the priority is transferred to other indoor units.
“Waiting” denotes the standby status in which the operation
lamp LED blinks (ON for 2.5 sec. and OFF for 0.5 sec.), and
the fan is stopped.
* In the fan mode, priority is transferred to a non-priority unit.

9.2. Airflow Direction Control (Cassette Type only)
The following shows how louver operation changes depending on the direction set with the AIR SWING button and other operating
conditions.
Cooling and Dry
Heating
· The louver stops at the CLOSE position when the power switch or breaker is ON.
· The louver stops at their current position when the power switch or breaker is OFF.
· Move the horizontal airflow direction control louver manually.

9.3. Indoor Fan Control
· The following shows how fan speed changes depending on the setting made with the FAN SPEED button and other operating
conditions.
· Actual fan speed may differ from that you set with remote control.

9.4. Drain Pump Control
Basic operation
· The drain pump starts 50 seconds after the indoor unit starts or the thermostat comes on (i.e., 10 seconds after the fan
motor starts).
The drain pump stops 30 seconds after the indoor unit stops or the thermostat turns off.
· The drain pump repeats a cycle of on for 30 seconds then off for between 50 and 90 seconds as long as the unit is
operating. Operation while the unit is off is determined by the difference between the temperature setting and the room
temperature.
Float switch operation
· When the float switch turns on for 10 seconds continuously, the thermostat of the indoor unit turns off and the drain pump
operates continuously.
· When the float switch stays on for 150 seconds continuously, the drain pump and indoor unit stop and the timer lamp
flashes indicating an H21 error.
