CS-E15CKP CU-E15CKP5 The frequency judgment will perform every 30 seconds. Nevertheless, the frequency is instructed to outdoor compressor after every 90 seconds except when either one of the below conditions is met: (a) The frequency judged changes from frequency number decreasing zones (Zone No. 0 or 1 or 2 or 3) to frequency number increasing zones (Zone No.
CS-E15CKP CU-E15CKP5 8.1.3. Indoor Fan Motor Operation There are 31 fan speed numbers assigned for different fan speed operation at designed conditions, as shown in below table. The fan speed can be set manually using remote control (5 speeds for cooling mode: Lo, Me-, Me, Me+, Hi; 5 speeds for heating: Lo, Me-, Me, Me+, Shi) or let it automatically changes depending on the operation and its environment.
CS-E15CKP CU-E15CKP5 8.1.4. Cooling Mode Automatic Indoor Fan Speed The automatic fan speed for cooling operation is as shown in below patterns (a → b → c → → h) with each pattern 10 seconds. The fan speed for each level (X or Y or Z) is as below table.

CS-E15CKP CU-E15CKP5 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).
CS-E15CKP CU-E15CKP5 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 (°)
CS-E15CKP CU-E15CKP5 The operation mode chart for this example is as shown in below figure and the operation mode to be performed will depend on indoor intake air temperature and outdoor air temperature at the time when the judgment is made.
CS-E15CKP CU-E15CKP5 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 3 minutes after power recover and the unit will operate as previous operation condition.
CS-E15CKP CU-E15CKP5 8.2.7. IPM (Power transistor) Prevention Control This control is applicable to all kinds of operation mode. A. DC Peak Current Control 1.

CS-E15CKP CU-E15CKP5 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 taken around the world to prevent this destruction.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 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.
CS-E15CKP CU-E15CKP5 1. The equipment must be earthed. It may cause electrical shock if grounding is not perfect. 2. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire.

CS-E15CKP CU-E15CKP5 CUTTING AND FLARING THE PIPING 1. Please cut using pipe cutter and then remove the burrs. 2. Remove the burrs by using reamer. If burrs is not removed, gas leakage may be caused. Turn the piping end down to avoid the metal powder entering the pipe.
CS-E15CKP CU-E15CKP5 CHECK THE DRAINAGE 11.3.5. CONNECT THE CABLE TO THE OUTDOOR UNIT • Open front panel and remove air filters. (Drainage checking can be carried out without removing the 1. Remove the control board cover from the unit by loosening front grille.)
CS-E15CKP CU-E15CKP5 12 Servicing 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).
