NOTES!

 

  Keep in mind that a shortage of airflow quantity or water leakage will result because the air 

conditioner will be operated outside the rated range of airflow quantity if the external static 
pressure is wrongly set. 

  The Sound Pressure Level will change if the external static pressure is wrongly set. 

5 Wiring Work 

WARNING!

 

Before obtaining access to terminals, all supply circuits must be disconnected. 

NOTES!

 

  Units must be earthed securely, or it may cause electric shock.   

  Please carefully read the wiring diagram before carry out the wiring work, incorrect wiring could 

cause malfunction or even damage the unit. 

  The unit should be powered by independent circuit and specific socket. 

  The wiring should be in accordance with related regulations in order to ensure the units reliable 

running. 

  Install circuit breaker for branch circuit according to related regulations and electrical standards. 

  Keep cable away from refrigerant pipings, compressor and fan motor. 

  The communication wires should be separated from power cord and connection wire between 

indoor unit and outdoor unit.   

  Adjust the static pressure via wired controller according to site circumstance. 

5.1 Connection of Wire and Patch Board Terminal 

(1)  The connection of wire (as shown in Fig.5.1.1) 

1)  Strip about 25mm insulation of the wire end by stripping and cutting tool. 
2)  Remove the wiring screws on the terminal board. 
3)  Shape the tail of wire into ring by needle nose plier, and keep the gauge of ring in 

accordance with screw. 

4)  Use the screwdriver for tightening the terminal.
