1. Determine hole positions according to left and righ t

side of the installation pla te. Th e hole cen ter is obtained

by measuring the distance as shown in the diagram above.

2. Dirll the piping plate hole with 65mm hole-core drill.

3. Drill the piping hole a t either the right or the left and the

hole should be slightly sla nted to the outdoor side.

4. Always take steps to prote ct the pipe when drilling metal

grid,metal plate or the like .

Please read these safety precauti onscarefully before installation

Be sure to fo llow a ll the preca utions below, they are all important for en surin g safety.

Th is s ymbol ind ica tes the po ssibility of death or serious in jury.

Th is s ymbol ind ica tes the po ssibility of i njury o r damage to property.

1) This equipment must be grounded and installed with ground leakage current breaker. It may cause

electrical shock if grounding is not perfect.

2) Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and

accumulates at surrounding of the unit, it may cause fire.

3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water

may enter the room and damage the furniture.

1) Install according to this installation instructionsstrictly. If installation is defective, it will cause water

leakage, electrical shock,or fire.

2) Use the included accessories parts and s pecified parts for installation. otherwise, it will cause the set

to fall, water leakage, electrical shock fire.

3) Install at a s trong and firm locationw hich is able to withstand the set s weight. If the strength is not

enough or installation is not properly done, the set will drop and cause injury.

4) For electrical work, follow the local national wiring standard, regulati on and this installation instructions.

An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or

defect found in electrical work, it will cause electrical shock fire.

5) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted

on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

6) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board

cover is not fixed perfectly,it will overheat at connection point of terminal, fire or electrical shock.

7) When carrying out piping connection, take care not to let air substances other than the specified

refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure

in the refrigeration cycle, explosion and injury.

8) Do not m odify the length of the power supply cord or use of extension cord, and do not share the

single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.

Electric safety regulatio ns for the initial Insta llatio n

1. If ther e is serious safety problem about the power supply, the technicians should ref use to insta ll

the ai r conditioner and explain to the client until the problem is solved.

2. Power voltage should be in the r ange of 90 %~110%of rated voltage.

3. The surge prote ctor and main power switch with a 1.5 times ca pacity of Max. Current of the

unit s hould be installe d in power circuit.

4. Ensure the air c onditioner is grounde d well.

5. Accor ding to the attac hed E lectrical C onnection Diag ram located on the panel of the outdoor unit

to connect the wire.

6. All wiring m ust comply with local and natio nal electrical codes and be inst alled byqualified and

skilled elec tricians.

8. An individu al branch circuit and single receptacle used on ly for this a ir conditio ner must b e

available. See the following table for suggested wire sizes and fuse specifications:

An all-pole disconnection device which has at least 3mm separation distance in all pole a nd a residual

current device(R CD) with t he rating o f not exce eding 30mA shall be incorporated in the fix ed wiring

according to the natio nal rule.

Electrical wor k

Install t he outdoor u nit on a rigid bas e to prevent increasing noise level a nd v ibration.

Determine the a ir o utlet directio n where the discharged air is not blocked.

In the c ase that the installat ion p lace is exposed to strong wind s uch as a seaside, make

sure the fan ope rati ng p rope rly by puttin g th e unit le ngthwise alo ng t he wall or us ing a dust

or s hiel d plates .

Specially in windy a rea, install the u nit to prevent the admission of wind. If need s uspending

installa tion, the inst allat ion bracket should accord w ith technique requiremen t in the

installa tion bracket diagram. The installation wa ll sh ould be solid bric k, c oncrete or th e sa me

inte nsit y construction, o r actions to reinf orce , damping supporting sh ould be taken.

The connection between br acke t and wall, bracket and t he air co nditioner should be firm,

When relocating the unit to another place, using vacuum pump to perform evacuation.

The ind oor unit and tubing between the indoor and outdoor unit must be leak teste d and evacuated

to remove any noncondensables and moisture from the system.
