Page 24: Airflow Direction
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 8.1.7. Airflow Direction 1. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes). 2. 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 controller).
Page 25: Automatic Mode Operation
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 2. Manual horizontal airflow direction can be set using remote controller; the angles of the vane are as stated below and the positions of the vane are as Figure 2 above. Pattern Airflow Direction Patterns at Remote Controller Vane Angle (°)

Page 28: Indoor Power Relay Control
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 8.2.3. Indoor Power Relay Control Power relay will turn on during operation or in progress of stopping operation. Although operation stops, the power relay continues on for three minutes. However, during instantaneous power failure (< 0.5s), power relay will turn off. Then, it will turn on two minutes after power recover and the unit will operate as previous operation condition.
Page 29 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 8.2.7. IPM (Power transistor) Prevention Control This control is applicable to all kinds of operation mode. A. DC Peak Current Control 1. When electric current to IPM exceeds set value of 22.5 A, the compressor will stop operate. Then, operation will restart after three minutes.
Page 30: Auto Restart Control
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 8.2.10. Minimum Operation Frequency Protection Control This control is applicable to all kinds of operation mode. When the compressor operate at frequency lower than 26 Hz (E9BKP) or 28 Hz (E12BKP) for 240 minutes, the operation frequency will be increased to 26 Hz (E9BKP) or 28 Hz (E12BKP) for two minutes.
Page 31 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 2. For Heating Mode operation, the compressor operating frequency is regulated in accordance to outdoor air temperature as shown in the below figures.

CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 10 Installation And Servicing Air Conditioner Using R410A 10.1. OUTLINE 10.1.1. About R410A Refrigerant 1. Converting air conditioners to R410A Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a destructive danger to the ozone layer in the earth´s upper stratosphere (20 to 40 km above the earth), measures have been...
Page 42 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 d. R410A refrigerating machine oil Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle.
Page 43: R410A Tools
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 10.2.2. R410A Tools 1. Cooper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type)) • This gauge makes it easy to set the clearance for the copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool.
Page 44 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 5. Charging hose • The pressure resistance of the charging hose has been raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports.
Page 45 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 8. Electronic scale for refrigerant charging • Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading.

CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 10.3. REFRIGERANT PIPING WORK 10.3.1. Piping Materials It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not used pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries.

Page 48: Refrigerant Piping
CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 b. Copper pipes Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use.
Page 49 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 10.4.2. Transferring (Using New Refrigerant Piping) 1. Removing the unit a. Collecting the refrigerant into the outdoor unit by pumping down The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low.
Page 50 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 5. Set the refrigerant cylinder onto the electronic scale, then correct the hose the cylinder and to the connection port for the electronic scale. (1)(2) Precaution: Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid without having to turn the cylinder around 6.
Page 51 CS-E9BKP CU-E9BKP5 / CS-E12BKP CU-E12BKP5 10.4.6. Brazing As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N2) flow.
