Position and Method of Installing Wire Controller

Position and Method of Installing Wire Controller


1. One end of the control wire of the manual controller is connected with main board of electric box of indoor unit inside, it should be tightened by wire clamp, the other end should be connected with the manual controller (installation sketch map as shown in below). The control wire be used for the indoor unit and manual controller, which is the special communication wire, the length is 8 meters, the material be adopted for the control wire should be metallic substance. The manual controller could not be disassembled and the communication wire be used for the manual controller should not be changed by users optionally, the installation and maintenance should be carried out by the professional personnel.

2. First select an installation position. According to the size of the communication line of the wire controller, leave a recess or a embedded wire hole to bury the communication line.

3.

If the communication line between the wire controller (85 x 85 x 16) and the indoor unit is surface-mounted, use 1# metallic pipe and make matching recess in the wall (refer to Figure 41); If concealed installation is adopted, 1# metallic pipe can be used (Refer to Figure 42).

4.

No matter if surface mounting or concealed mounting is selected, it is required to drill 2 holes (in the same level) which distance shall be the same as the distance (60mm) of installation holes in the bottom plate of the wire controller. Then insert a wood plug into each hole. Fix the bottom plate of the wire controller to the wall by using the two holes. Plug the communication line onto the control panel.

Lastly install the panel of the wire controller.

Caution:

During the installation of the bottom plate of the wire controller, pay attention to the direction of the bottom plate. The plate

’s side with two notches must be at the lower position, and otherwise the panel of the wire controller cannot be correctly installed.

Caution:

1.

The communication distance between the main board and the wire controller is 8 meters.

2. The wire controller shall not be installed in a place where there is water drop or large amount of water vapor.



Caution:

Before installing the electrical equipment, please pay attention to the following matters which have been specially pointed out by our designers:

(1) Check to see if the power supply used conforms to the rated power supply specified on the nameplate.

(2) The capacity of the power supply must be large enough.

(3) The lines must be installed by professional personnel.

An electricity leakage protection switch and an air switch with gap between electrode heads larger than

3mm shall be installed in the fixed line.

1.

Connection of single wire

(1)

Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.

(2) Remove the screw at the terminal board of the air-conditioning unit.

(3) User pliers to bend the end of the single wire so that a loop matching the screw size is formed.

(4) Put the screw through the loop of the single wire and fix the loop at the terminal board.

2. Connection of multiple twisted wires

(1) Use wire stripper to strip the insulation layer (10mm long) from the end of the multiple twisted wires.

(2) Remove the screw at the terminal board of the air-conditioning unit.

(3)

Use crimping pliers to connect a terminal (matching the size of the screw) at the end of the multiple twisted wires.
