19.3. Refrigerant charging • • • • For twin and triple-type systems The pipe length is the total of the branch pipe (L) and the junction pipes (la → lb → lc in order from the thickest diameter). At the point where the pipe length exceeds 30 m, determine the amount of refrigerant for the remaining liquid-side pipe diameters and pipe lengths from the following table in order to charge the system.
20 WIRING MISTAKE PREVENTION Improved quality of installation work through adoption of an “Connection error prevention” circuit which prevents wiring mistakes Connection errors with the control wires and the power supply wires will not only contribute to burning-out of the control circuit board, but can also cause large-scale working losses and affect reliability.

26 CONTROL Description of basic Functions 26.1. 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.
26.2. 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.
(*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.
<When hot start operation is cancelled by time> 2. When defrosting is completed a. Start Hot start control commences when defrosting is completed. b. 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.
<When hot start operation is cancelled by time> 26.5. Indoor unit fan control when thermostat is off during heating mode operation When the thermostat of the indoor unit turns off during heating mode operation, the indoor unit fan operates for 2 minutes at LOW and then stops.
26.7. 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.
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. Thermostat characteristics during dry mode. During dry mode operation, cooling mode operation is carried out in accordance with the indoor temperature as shown in the table below.
c. Thermostat characteristics during cooling mode and heating operation The thermostat on/off characteristics in both operation modes are given in the table below.
26.9. Indoor unit fan control 1. Fixing at LO, MED or HI When LO, MED or HI is set, the relay switches and operation is carried out at that setting. 2.
