After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's manual. Moreover, ask the customer to keep this sheet together with the owner's manual.

WARNING

CAUTION

WARNING

This system should be applied to places of office, restaurant, residence and the like. Appliaction to inferior environment such as engineering shop could cause equipment malfunction. Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires. Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires. When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you purchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur,there is the danger of a resultant oxygen deficiency accident. For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit. Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit. For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires. Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.

Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can

also result in heat generation or fire.

SAFETY PRECAUTIONS

WARNING

When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (please see nameplate) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing. Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refigerant leakage. The position of indoor unit must be above the floor 2.5m.

CAUTION

Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightening rod or a telephone ground wire. Improper placement of ground wires can result in electric shock. The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock. Do not install the unit where there is a concern about leakage of combustible gas.

The rare event of leaked gas collecting around the unit could result in an outbreak of fire.

For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

When it is not lower than 200Pa after 2 hours or more vacuumizing, vacuumize for another 1 hour. If after more than 3 hours vacuumizing it is still not lower than 200Pa, the leak part shall be found. When it is lower than 200Pa after more than 2 hours vacuumizing, close both the valve VL and VH of the diverter, then close the vacuum pump. Place it there to observe if the vacuity changes. If it changes, it indicates leakage exists, so the leak part shall be found. After finishing the above vacuumizing work, replace the vacuum pump with refrigerant tank and turn to the refrigerant charging procedure.

V Charging of refrigerant

1.Calculation of additional charging amount of refrigerant

After finishing vacuumizing work, replace the vacuum pump with refrigerant tank and turn to the refrigerant additional charging procedure.

Calculation of additional charging amount of refrigerant

Quantity of filled refrigerant before the machine leaving factory does not consider supplement for extension tubes while spot installation. After practical installation is finished, it is necessary to fill supplement refrigerant into extension tubes provided that the length of spot liquid tube>0m. Filling method is as the following.

Calculation method:

Quantity of supplement refrigerant is determined by specification and actual length of the spot liquid tube.

Calculation formula:

Quantity of spot supplement refrigerant = actual length necessary supplement refrigerant quantity per meter of the tube. E.g.: Uuantity of spot supplement refrigerant(R407C)=(L1-5) 0.035kg/m) L1: Actual total length of 6.35 liquid tube in one system Uuantity of spot supplement refrigerant(R407C)=[(L2-5)+(L3-5)] 0.035kg/m) L2, L3: Actual length of 6.35 liquid tube in the B1, B2 way.

2.Charging of refrigerant

Close all valves of outdoor unit, and charge refrigerant from air discharge valve of gas side. When can not charge the specified amount, firstly, open all the valves, both liquid side and gas side, of outdoor unit,then switch the valve of gas side to close state a little.Under this condition, do cooling operation and charge refrigerant from the discharge valve of gas side. At this time, adjust the valve of the refrigerant tank to make the refrigerant in Gas State when it is absorbed by system. When refrigerant leakage making refrigerant lack in system occurs, all of the system shall be recovered and recharge it according to specified amount.

3.Opening of the refrigerant pipe

Open all the valves of outdoor unit

Installation procedure Refrigerant

! Warning

The electric wiring work shall be conducted by qualified electricians according to the installation instructions. A separate power circuit shall be used. Insufficient power cord amperage or improper wiring will cause danger of electric shock or fire. During wiring connection, the power cord shall be of the specified cable and reliably fastened so that external forces applied to the cable wouldnt transfer to the terminals. Improper connection or fastening will cause danger of heating, fire etc.The power cord must be fitted with a grounding wire. Grounding shall be made as specified. Unreliable grounding will cause electric shock. The grounding wire shall not be connected to the gas pipeline, water pipeline, thunder arrestor and telephone wire

! Caution

A current leakage breaker shall be installed, otherwise it electric shock would happen easily. If the power cord is damaged, it must be replaced by the manufacturer or its service center or similar personnel to avoid risks. The power supply to the indoor unit shall be laid in complying with the operational instruction manual. The electric wiring shall avoid contacting with the high temperature part of the piping so as to prevent the cable insulation melts and cause dangers. After connected on the terminal block, the wires shall be bent to U form and then fastened with wire clip. The control wiring and refrigerant piping may be laid and fastened together. Before completion of vacuum pumping of the refrigerant pipe system, do not electrify the indoor unit. The power cord of the indoor unit and connection wiring between indoor and outdoor units shall be laid out according to the operational instruction manual of the indoor unit. The connection of the power cord shall comply with the local regulations.

The power supply wiring connection should meet the local regulation.

!

Wiring connection method : (the wiring diagram is attached inside the machine)

1) Ring terminal connection method

If there is a ring at the end of the connection wire, the wire connection method is as shown in the right figure. Remove the terminal screw and insert it through the ring at the connection wire end, then connect to the terminal board and fasten the screw.

2) Straight terminal connection method

If there isnt a ring at the end of the connection wire, the connection method shall be: loosen the terminal screw, insert the connection wire end completely into the terminal board and fasten the screw. Pull the connection wire outwards slightly to confirm it is clamped tightly.

3) Clamping method of the connection wire

After wire connection is finished, the connection wire must be pressed tightly with wire clips, which shall apply to the outer sheath of the connection wire.

Connection method for ring terminal

Wire connection for built-in indoor unit

Insert from outside the connection wire and signal transmission wire through the wall hole with pipeline already arranged. Pull out the front ends of connection wire and signal wire and make a circle on the signal wire. Connect the connection wire according to the connection method and indoor and outdoor wiring diagram. Pull the connecting conductor outwards slightly to confirm it is clamped tightly. Connect the plug for connecting the signal wire with the plug of the signal wire connected from the indoor unit. After wire connection is finished, install wire clips using the same method for connection wire clamping.

Note: When connecting the indoor unit and the outdoor unit, please do connect the wir es with the same color terminals.

Notes:

Before connecting the conductors between indoor unit and outdoor unit, check for the number on the indoor and outdoor units connecting terminals. Connect the terminals with the same color and number with a wire. Wrong connection would damage the controller of the air conditioner or the machine couldnt operate. Do not connect the connection wire and signal wire with the same cable. They shall be connected respectively to ensure system normal operation.

Explanation:

For the wall mounted indoor unit AS072/092/122/142/182XCBAA, you can select the horse power and the indoor fan

motor speed by adjusting the jumper. When out of factory, the jumper state will be as follow:

For AS072/092XCBAA PCB, jumper J27 is unconnected;

For AS122/142XCBAA PCB, jumper J26 is unconnected;

For AS182XCBAA PCB, jumper J25 is unconnected;

And jumper 24 is used to select the temperature compensation, if it is connected, the temp. compensation is available,

while if it is unconnected, the temp. compensation function is cancelled.
