• The electrical power line and signal lines must be fastened tightly.
• Every indoor unit must have a ground connection.
• The power line should be enlarged if it exceeds the permissible length.
• Shielded lays of all the indoor and outdoor units should be connected together, with the shielded lay at the side of signal lines of outdoor units grounded at one point.
• It is not permissible if the whole length of the signal line exceeds 1000m.

Two wired controllers control one high wall unit One wired controller controls one high wall unit

|
---|---

Recommended: One wired controller controls more than one indoor unit (limited in high walls)

Not recommended: One wired controller controls more than one indoor unit (ordinary indoors)

High wall wired controller wiring instruction:

1. One wired controller controls one high wall unit (one to one), and connects the wires of the wired controller to the CN22 terminal on PCB directly.
2. Two wired controllers control one high wall unit (two to one), and connect the wires of wired controllers 1 and 2 respectively to CN22 and CN22-1 on PCB.
3. One wired controller controls more than one unit (one to more), limited in high wall units is recommended and mixed different type of indoor units is not recommended. It’s easy to do wrong wiring when there’re many different types indoors.
   If you choose one to more (mixed different types of indoor units), please follow the principles below: A
   a. The communication wires of wired controller inlet or outlet high wall units are 3 cores. It means to connect all the wires “ABC”.
   b. When one wire controller connects to more indoors, all the wires between terminals are 3 cores.
   When other indoor units are slave ones of the wired controller, please move off the “A” wire between indoor and PCB CN22 terminals. It means that when others indoors are slave ones of the wired controller, no need to connect “A” wire.
   c. When the “A” wire is not connected to other ordinary indoors which are the slave ones of the wired controller, please do some insulation on it and avoid touching another electric circuit.

Dipswitch Setting

• The dipswitch is dialed to “On” position with the overline at the state of strapping if the code or overline status is “1” The dipswitch is dialed to “Off”position with the  overline at the state of disconnection if the code or overline status is “0”
• In the table below, the choice in the box “(” refers to the setting of the socket/overline before delivery.

Indoor Units PCB
In the following table, 1 represents On and 0 represents Off.

Test Run

Before Test Run

• Before switching it on, test the supply terminal tier (L, N terminals) and grounding points with 500V megaohm meter and check if the resistance is above 1MQ. It can’t be  operated if it is below 1MQ.
• Connect it to the power supply of outdoor units to energize the heating belt of the compressor.
  To protect the compressor at startup, power it on 12 hours prior to the operation.

Check if the arrangements of the drainpipe and connection line are correct.
The drainpipe shall be placed at the lower part while the connection line placed at the upper part. Heat preservation measures should be taken such as winding the drainpipe  esp. in the indoor units with heating insulating materials.
The drain pipe should be made a slope type to avoid protruding at the upper part and concaving at the lower part on the way.

Checkup of Installation

• check if the mains voltage is matching
• check if there is air leakage at the piping joints
• check if the connections of mains power and indoor & outdoor units are correct
• check if the serial numbers of terminals are matching
• check if the installation place meets the requirement
• check if there is too much noise
• check if the connecting line is fastened
• check if the connectors for tubing are heat insulated
• check if the water is drained to the outside
• check if the indoor units are positioned

Ways of Test Run

Do ask the installation personnel to make a test run. Take the testing procedures according to the manual and check if the temperature regulator works properly.
When the machine fails to start due to the room temperature, the following procedures can be taken to do the compulsive running. The function is not provided for the type with remote control.

• Set the wired controller to refrigerating/heating mode, and press the “ON/OFF” button for 5 seconds to enter into the compulsive refrigerating/heating mode. Repress the “ON/OFF” button to quit the compulsive running and stop the operation of the air conditioner.
