Fig.15

Fig.15 shows the installation steps of the wired remote controller, but there are some issues that need your attention.

(1). Prior to the installation, please firstly cut off the power supply of the wire buried in the installation hole, that is, no operation is allowed with electricity during the whole installation.

(2). Pull out the four-core twisted pair line from the installation holes and then let it go through the rectangular hole behind the soleplate of the wired remote controller.

(3). Stick the soleplate of the wired remote controller to the wall over the installation hole and then fix it with screws M4X25.

(4). Insert the four-core twisted pair line into the slot of the wired remote controller and then buckle the front panel and the soleplate of the wired remote controller together.

(5). Finally, fix the front panel and the soleplate of the wired remote controller tightly by screws

ST2.9X6.

CAUTION!

Please pay special attention to the followings during the connection to avoid the malfunction of the air conditioning unit due to electromagnetic interference.

① .

Separate the signal and communication lines of the wired remote controller from the power

14

Wired Remote Controller XK19 cord and connection lines between the indoor and outdoor unit, with a minimum interval of 20cm, otherwise the communication of the unit will probably work abnormally.

② .

If the air conditioning unit is installed where is vulnerable to electromagnetic interference, then the signal and communication lines of the wired remote controller must be the shielding twisted pair lines.
