Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation Diagram. Please wrap the insulated piping end to prevent water from going inside the piping. If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by using POLY-E FOAM with thickness 6 mm or above. 11. 3. 6. OUTDOOR UNIT DRAIN WATER · Water will drip from the basepan hole area during defrost function. To avoid water dripping, do not stand or place objects at this area. 11. 3. 7. CHECK THE DRAINAGE · Open front panel and remove air filters. (Drainage checking can be carried out without removing the front grille. ) · Pour a glass of water into the drain tray-styrofoam. · Ensure that water flows out from drain hose of the indoor unit. 11. 3. 8. EVALUATION OF THE PERFORMANCE · Operate the unit at cooling operation mode for fifteen minutes or more. · Measure the temperature of the intake and discharge air. · Ensure the difference between the intake temperature and the discharge is more than 8°C. 29 CS-E9EKEB CU-E9EKEB / CS-E12EKEB CU-E12EKEB 12 Operation And Control 12. 1. Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature. 12. 1. 1. Internal Setting Temperature Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit. 12. 1. 2. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes). Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control). 12. 1. 2. 1.
