EKEXFCBAV3 EKEXDCBAV3 CONTENTS Installation and operation manual Option kit for combination of Daikin condensing units with field supplied evaporators Page Introduction ............................................................... 1 We distinguish 2 different control boxes, each with its own application and installation requirements. ■ ■ Operation with 0–10 V input to control the capacity An external controller is needed to control the capacity.
NAME AND FUNCTION OF PARTS (See figure 1 and NOTE figure 2) Parts and components 1 Outdoor unit 2 Control box (EKEXFCB / EKEXDCB) 3 Air handling unit (field supply) 4 Controller (field supply) 5 Field piping (field supply) 6 Expansion valve kit ■ If conflicting result, volume selection has priority over capacity. ■ The expansion valve is an electronic type, it is controlled by the thermistors that are added in the circuit.
■ Keep the space in front of the boxes free for future maintenance. 4 Remove the pipe fixing clamp (C) by unscrewing 2x M5. ■ Keep evaporator (air handling unit), power supply wiring and transmission wiring at least 1 m away from televisions and radios. This is to prevent image interference and noise in those electrical appliances. (Noise may be generated depending on the conditions under which the electric wave is generated, even if 1 m is kept.) 5 Remove the upper and lower pipe insulations.
INSTALLATION OF THE ELECTRICAL CONTROL BOX (See figure 4 and figure 6) Electrical work 1 Open the electrical box cover (A). 2 Push out ONLY the second lower wire intake hole (B) from inside to outside. Do not damage the membrane. 3 Pass valve cable (with wires Y1 ... Y6) from the control box through that membrane wire intake hole and connect the cable wires into the terminal connector (C) following instructions as described in step 4.
Precautions Connecting the wiring: EKEXFCBAV3 ■ Thermistor cable and remote controller wire should be located at least 50 mm away from power supply wires and from wires to the controller. Not following this guideline may result in malfunction due to electrical noise. ■ Connect the wires to the terminal board according to the wiring diagram in figure 3. See figure 4 for wiring intake in the control box. The wiring intake hole indication H1 refers to the H1 cable of the corresponding wiring diagram.
Connecting the wiring: EKEXDCBAV3 ■ Connect the wires to the terminal board according to the wiring diagram in figure 5. See figure 6 for wiring intake in the control box. The wiring intake hole indication H1 refers to the H1 cable of the corresponding wiring diagram. ■ Connect cables according to specifications of the next table.
INSTALLATION Fixation of the thermistor OF THERMISTORS Refrigerant thermistors ■ Put the thermistor wire slightly down to avoid water accumulation on top of the thermistor. ■ Make good contact between thermistor and evaporator. Put the top of the thermistors on the evaporator, this is the most sensitive point of the thermistor. Location of the thermistor A correct installation of the thermistors is required to ensure a good operation: 1.
Installation of longer thermistor cable (R1T/R2T/R3T) ■ In case of poor distribution in the evaporator, 1 or more passes of the evaporator may freeze-up (collect ice) ➞ put the thermistor (R2T) on this position. ■ Make sure that the evaporator fan keeps operating, even when the outdoor unit compressor stopped operating (only at the moment of "anti-freeze-up" control). ■ Depending on operation conditions (e.g.
Program the field supplied controller to generate a 0–10 V signal within conditions as listed. Also refer to the graphic and further data in this paragraph for more details.
If the system does not operate at all ■ Check if there is a power failure. Wait until power is restored. If power failure occurs during operation, the system automatically restarts immediately after the power supply recovers. ■ Check if the fuse has blown or breaker has been tripped. Change the fuse or set the breaker. NOTES If the system stops operating after operation is complete ■ Check if the air inlet or outlet of outdoor or evaporator (air handling unit) is blocked by obstacles.
