Clean Design
High Comfort
High Efciency
The outdoor unit takes no screw clean design in the top cover, this design makes people comfort when they are watching the outdoor unit;
New outdoor unit and indoor unit design to get a ultra high SEER/SCOP A+++/A++ which is reaching the world class energy efciency (3U55)
The new outdoor unit takes 550mm diameter large fan design, multi split II outdoor unit can provide same air ow but with lower fan rotation speed, then the sound level reduce 3-4 dB(A) comapred with rst generation multi split outdoor unit;
550mm

Installation Friendly
External General Stop Valve
Easy Start Up & Maintenance
The outdoor unit takes external general stop valve in all outdoor unit design, installer can vaccum/charge just one time with no extra dismantlement, save lots of time;
In start up & maintenance, PC monitor can connect with outdoor unit by TD-02, read all indoor unit & outdoor unit running parameter, also with the function to show parameter & curve. When malfunction happens, show failure code.

Selection Of Installation Place
<Don't discard any accessories until comp>
(1) Installation place shall meet the following and agreed by customers
(2) Ceiling height Indoor unit can be installed on ceiling of 2.5-3m in height. (Refer to foeld setting and installation manual of ornament panel.) (3) Install suspending bolt. Check if the installation place is strong enough to hold weight. Take necessary measures in case it is not safe. (Distance between holes are marked on paper pattern. Refer to paper pattern for place need be reinforced)
• Determine the way tocarry unit toinstallation place.
• Don't remove packing until unit reaches installation place.
• If unpacking is unkavoidable, protect unit properly.
• Place where proper air ow can be ensured.
• Noblock toair ow.
• Water drainage is smpoth.
• Place strong enough to support unit weight.
• Place where inclination is not evident on ceiling.
• Enough space for mainenance.
• Indoor and outdoor unit piping length is within limit. (Refer to Installation Manual for outdoor unit.)
• Indoor and outdoor unit, power cable, inter unit cable are at least 1m away fromT.V. radop. This is helpful to avoid picture disturbance and noise. (Even if 1m iskept, noise can still appear if radio wave is strong)

(2) Cut an opening in ceiling for installation if necessary. (When ceiling already exists.)
(3) Install a suspending bolt. (Use a M10 bolt)
• Refer to paper pattern for dimension of ceiling hole.
• Connect all pipings (Refrigerant, water drainage), wirings (Inter unit cable) to indoor unit, before installation.
• Cut a hole in ceiling, may be a frame should be used to ensure a smooth surface and to prevent vibration.
• Contact your real estate dealer
• To support the unit weight, anchor bolt shall be used in the case of already exists ceiling. For new ceiling, use builtin type bolt or parts prepared in the eld.
• Before going on installing adjust space between ceiling. Note: All the above mentioned parts shall be prepared in eld.

Installation of Indoorunit
(1) Install unit temporally Put suspending bracket on the suspending bolt. Be sure to use nut and washer at both ends of the bracket.
(2) As for the dimensions of ceiling hole, see paper pattern. Ask your real estate dealer for details. Center of the hole is marked on the paper pattern. Center of the unit is marked on the card in the unit and on the paper pattern. Mount paper pattern ⑤ onto unit using 3 screws
⑥
Fix the corner of the drain pan at piping outlet.
In The Case of New Ceiling
<Aer Inslallalion on the Ceiling>
(3) Adjust unit to its right position. (Refer to preparation for the installation-(1))
(4) Check units horizontal level. Watert pump and ating switch is installed inside indoor unit, check four corners of the unit for its level using horizontal compartor or PVC tube with water. (If unit is tilting against the direction of water drainage, problem may occur on oating switch, causing water leakage.)

Put suspending bracket on the suspending bolt. Be sure touse nut and washer at both ends of the bracket. Fix the bracket rmly.
• Outdoor is precharged with refrigerant.
• Be sure tosee the Fig.1, when connecting and removing piping from unit.
• For the size of the are nut, please refer to Table 1.
• Apply refrigerant oil at both inside and outsid of lare nut. Tighten it band tight 3-4 turns then tighten it.
• Use torque specied in Table 1. (Too much force may damage are nut, causing gas leakage).
• Check piping joints for gas leakage. Insulate piping as shown in Fig. below.
• Cover joint of gas piping and insulator 7 with seal.
(2) Adjust the height and position of the unit. (Refer to preparation for the installation (1) ).
(3) Proceed with ③ and ④ of "In the case of new ceiling".

Installation of Waterdrainage Pipe
(1) Install water drainage pipe
• Pipe dia, shall be equal or larger than that of unit piping. (Pipe of polyethylent; size 25mm; O.D 32mm)
• Drain pipe should be short, with a downward slope at least 1/100 toprevent air bag from happening.
• If downward slope can t be made, take other measures to lift it up.
• Keep a distance of 1-1.5m between suspending brackets, tomake water hose straight.
• Use the self-provided stiff pipe and clamp ① with unit. Insert water pipe into water plug until it reaches the white tape. Tighten the clip until head of the screw is less than 4mm from hose.
• Wind the drain hose to the clip using seal pad ⑨ .
• Insulate drain hose in the room.

The slope of water drain hose (1) shall be within 75mm, don't apply too much force on it. If several water hoses join together, do as per following proceedures. Specieations of the water hoses shall meet the requirements for the unit running.
Note:
(2) Check if water drainage is smooth after installation.
• Check whether indoor unit is horizontal with leveler or polythene pipe lled with water, and check that the dimension of the ceiling opening is correct. Take off the lever gauge before install the ornament panel.
• Fasten the screws to make the height difference between the two sides of indoor unit less than 5mm.
• First x it with screws temporally.
• Fasten the two temporally xing screws and other two, and tighten the four screws.
• Connect the wires of synchro-motor.
• Connect the wire of signal.
• If no response of remote controller, check whether the wiring is correct, restart remote controller 10 seconds after shut off power supply.
• Install the panel board in the direction shown in the gure. The incorrect direction will result in water leakage, meanwhile swing and signal receiving are displayed that cannot be connected.
• Charge, through air outlet or inspecting hole, 1200ccd water to see water drainage.
• Check water drainage in cooling operation.
