A separate power circuit shall be supplied and connected by a qualified electrician according to the wiring rules specified in the corresponding national standard. A current leakage breaker must be installed. The connection method of power cord is " Y " type. If the power flexible cord is damaged, it shall be replaced by the manufacturer or its service department or similar qualified technician so as to avoid risks. Power cord plug: L should be connected to the live wire, N should be connected to the neutral wire and to the ground wire. Connection wire size: 3 G (1.0-1.5) mm2, type of H05RN-F. Signal transmission wire size:H05RN-F 2 x (0.75-1.5) mm2 (shielded wire). Power cord, connection wire and signal wire shall be provided by the user. Indoor unit 1. Select suitable places the outlet air can be sent to the entire room, and convenient to lay out the connection pipe, connection wire and the drainage pipe to outdoor. 2. The ceiling structure must be strong enough to support the unit weight. 3. The connecting pipe, drain pipe and connection wire shall be able to go though the building wall to connect between the indoor and outdoor units. 4. The connecting pipe between the indoor and outdoor Fig 1 units as well as the drain pipe shall be as short as possible. (See Figure 1) 5. If its necessary to adjust the filling amount of the refrigerant, please refer to the installation manual attached with the outdoor unit. 6. The connecting flange should be provided by the user himself. 7. The indoor unit have 2 drainage outlet, one outlet be jamedwith rubber cap, during installation only use another outlet (In/Out liquid pipe side). When necessary, use the two outlet at the same time. 8. Not place the TV., equipment, facility, piano etc, expensive goods below the AC, prevent the water dropping down from the AC and lead to damage to the goods. 22 Installation Procedure After selecting the unit installation location, proceed the following steps: 1. Drill a hole in the wall and insert the connecting pipe and wire through a PVC wall-through tubepurchased locally. The wall hole shall be with a outward down slope of at least 1/100. (SeeFigure 2) 2. Before drilling check that there is no pipe or reinforcing bar just behind the drilling position. Drilling shall avoid at positions with electric wire or pipe. 3. Mount the unit on a strong and horizontal building roof. If the base is not firm, it will causenoise, vibration or leakage (see Figure 6). 4. Support the unit firmly. 5. Change the form of the connection pipe, connection wire and drain pipe so that they can go through the wall hole easily.

Use glue to seal the interface closely. Recommend the distance between the air return duct and the wall is more than 150mm. The distance between air duct outlet and air conditioner outlet is according to the length of actually installedair duct and in service behavior of the static pressure terminal: Installation sketch map for long and short airduct is showed below, when connect to short air duct, using low static terminal (terminal color is write), thedistance between air duct outlet and air conditioner outlet is no more than 0.5m; when connect to long air duct, using middle static terminal (terminal color is red), the distance between air duct outlet and air conditioner outletcould be within 5m at this point. air return shutter air return duct sling dog drain piping transition air duct air outlet duct air diffuser joint of air diffuser Figure 5 Drain piping of condensed water should keep a downhill grade of 1% or more. Use insulating pipe to coverthe drain piping of condensed water to keep warmth. As figure shown, suspend and install the unit.
