Page 3: Service Information
1 SERVICE INFORMATION 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 soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C). Pb free solder will tend to splash when heated too high (about 1100°... -

27 CONTROL Description of basic Functions 27.1. Cooling mode operation time chart (*1) Outdoor unit fan start control during cooling At the start of cooling mode and drying mode operation, the outdoor unit heat exchanger outlet temperature is detected in order to set the fan speed. - Page 61 27.2. Freezing prevention control 1. Operation During cooling mode operation, after 9 minutes have passed since the compressor turned on, the outdoor unit will stop its operation when the temperature detected by the indoor unit pipe temperature sensor is 2°C or lower. The indoor unit continues operating at the fan speed set by the remote control.
- Page 62 (*2) Outdoor unit fan control during heating mode operation When the compressor is on during heating mode operation (except during defrosting and when the liquid bypass valve is on), the outdoor unit fan is controlled by means of input (CN2) indicating whether the contact of the heating pressure switch on the outdoor unit circuit board is open or closed.

Operation “PREHEAT” appears on the remote control display. (Other displays remain unchanged) The indoor unit fan stops. In addition, during hot starting, the louvre stays at the horizontal position (angle 0°C). c.

- Page 65 27.7. Defrost mode operation time chart 1. Start and completion of defrosting a. Start During heating mode operation (including automatic heating), after the 45 minutes of defrosting cycle time has passed, defrosting starts if the temperature detected by the outdoor unit heat exchanger outlet sensor is 2°C or lower continuously for 5 minutes.
- Page 66 If jumper wire J3 on the indoor unit circuit board is disconnected, the thermostat characteristics during heating become 2K or higher. NOTE: If the remote control display setting temperature (To) is 29°C or higher, the heating thermostat turns on when the room temperature is 31°C. 2.
