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.

CS-ME7CB1P / CS-ME 10CB1P / CS-ME12CB1 P / CS-ME14CB1 P / CS-ME10CD3P / CS-ME14CD3P

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

· W hen the float switch turns on for 10 seconds continuously, the thermostat of the indoor unit turns off and the drain pump

operates continuously.

· W hen 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.

9.5. Auto Restart Control

· if there is a power failure, operation will automatically be restarted when the power is resumed. It will start with the previous

operation mode and airflow direction. (Time Delay Safety Control is valid)

1. Control start conditions

<1> The 24-hour timer must not be set.

<2> The sleep timer must not be set.

Auto restart control is not available when timer or sleep mode is set.

2. Description of control

<1> In the case of manual operation, the operation mode, temperature setting, fan speed and airflow direction before the power is turned off are restored.

<2> In the case of automatic operation, after the power is restored operation starts with the determination of the mode.

<3> While the air conditioner odour clear timer has been set, the setting is cancelled, and operation is transferred to the mode before the power is turned off.

<4> While the air conditioner odour clear operation (with timer / without timer setting) are being performed, both of these operations are completed, and operation is transferred to the operation mode prior to these operations.

Example: When the power is turned off during an outdoor unit cooling operation
