Page 16: Operation Details
CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8 Operation Details 8.1. 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. - Page 17 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD Table (d): Indoor Air Temperature Shifting 1. Target room temperature shift value (dGetaDst) • To offset the absolute gap between detection temperature with actual room temperature. • The heat exchanger unit’s temperature is different based on operation mode, it become the action operation mode value.
- Page 18 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8.1.2. Compressor Operation Frequency 8.1.2.1. The frequency determination method (Cooling operation control) 8.1.2.1.1. Basic specification The domain directions data (intake-setting) transmitted from the interior of a room determines a changed part of frequency. Then, a directed changed part changes frequency to the present frequency.
- Page 19 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8.1.2.1.4. The frequency changed method 1. After shifting to relative control, (intake-setting) is every 60 seconds, A tap is adjusted according to the domain and frequency changes relatively to present condition. 2. Intake-setting to other domains by load sudden change (remote control setting, open air introduction, etc.). When it moves, it has the following renewal of data, an addition and subtraction tap is switched.
- Page 20 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8.1.2.2.2. Initial frequency determination After a starting control end, initial frequency (absolute value) is determined and is immediately shift. However, the domain of Fhmax is judged instantly. 8.1.2.2.3. Change frequency determination When directions of Fhmax determined from mentioned initial frequency, (intake-setting) relativity control. Fhmax continued until (If other directions came by protection control, priority is given there) room temperature is reached, it shifts to relative control after moving to change frequency.
- Page 21 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8.1.2.2.4. The frequency changed method 1. When intake-setting remains for 30 seconds in a domain after shifting to relative control, a tap is adjusted according to the domain and frequency changes relatively to the present condition.
- Page 22 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 8.1.2.3.3. The frequency change method 1. When (suction-setup) remains in a domain for 30 seconds, after shifting to relative control, a tap is adjusted according to the domain and frequency changes relatively to the present condition.

Page 62: Tools For Installing/Servicing Refrigerant Piping
CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 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 63 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 11.2.2. R410A Tools 1. Copper 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 64 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 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 65 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 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-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 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 69 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 11.4.2. 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 70 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 11.4.5. Recharging Refrigerant During Servicing When recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure. 1. Connect the charging hose to the service port of the outdoor unit.
- Page 71 CS-E9DKDW CU-E9DKD / CS-E12DKDW CU-E12DKD 11.4.6. 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 (N ) flow.
