Selecting the MountingLocationsDetermine the mounting location withthe customer as follows:

Indoor Unit• Install the indoor unit level on a

strong wall which is not subjectto vibration.

• The inlet and outlet ports shouldnot be obstructed. The air shouldbe able to blow throughout theroom.

• Install the indoor unit whereconnection to the outdoor unitcan be made easily.

• Install the unit where the drain pipecan be easily installed.

• Take servicing into considerationand leave the spacing shown inFigure 2. Also, install the unit wherethe filter can be easily removed.

• Do not install the unit near a sourceof heat, steam, or flammable gas.

• Do not install the unit where it willbe exposed to direct sunlight.

Outdoor Unit• Leave the spacing shown in

Figure 3 for required air flow.• If possible, do not install the unit

where it will be exposed to directsunlight.

• Do not install the unit near a sourceof heat, steam, or flammable gas.

• Do not install the unit where astrong wind consistently blows orwhere it is extremely dusty.

• Do not install the unit where peoplepass in front of the fan dischargegrille.

General Instructions• All phases of the installation of this

air conditioning system mustconform to all national, provincial,state and local codes.

• Read these instructions carefullyand completely before attemptingto install the air conditioningsystem.

• For the air conditioning system tooperate properly and reliably, itmust be installed in accordancewith these instructions.

• The maximum length of the pipingis to10 meters. If the units arefurther apart than this, correctoperation can not be guaranteed.

Indoor Unit InstallationThe piping can be connected in thefive directions indicated by 1, 2, 3, 4and 5 in Figure 4. When the piping isconnected in direction 3, 4 or 5 cutalong the piping groove in the side orbottom of the front cover with a saw.

1. Installing the Wall Bracket1. Install the wall bracket so that it

is level from side to side. If thewall bracket is tilted, condensatewater will drip to the floor.

2. Install the wall bracket so that itis strong enough to withstand aweight of 50 kilograms or more.

3. Fasten the wall bracket to thewall with 6 or more screwsthrough the holes near the outeredge of the bracket.

4. Check to insure that there is norattle of the wall bracket againstthe wall.

Caution• Always cut the wall hole uniformly

and straight when the wall pipe isnot used. If the hold center is notaligned, condensate leakage canoccur.

• If the wall pipe is not used, thewiring cable connecting the indoorand outdoor units may becomefrayed and cause electric currentleakage to earth.

3. Forming the Indoor DrainHose and Refrigerant Pipes1. For 3 Left piping. 4 Right piping,

5 Bottom piping: Perform.“Indoor Unit Wiring” beforeperforming the following steps3.2 through 3.6.

2. Wrap the pipes of the indoor unitthat are visible from the insidewith decorative tape (Figure 7).

3. Insert the indoor unit piping intothe wall hole and bind the drainhose and pipe together withvinyl tape (Figure 8).

2. Cutting the Hole in the Wallfor the Connecting Piping1. Cut a 65 mm. diameter hole in

the wall at the desired positionshown in Figure 6.

2. Cut the hole so that the outsideend is lower (5-10 mm.) than theinside end.

3. Cut the wall pipe length to matchthe wall thickness, insert it intoan accessory wall cap, fasten thecap with vinyl tape, and insert thepipe through the wall hole. (Wallpipe and wall cap are procuredat the site).

4. For 3 left piping and 4 rightpiping, cut the hole sligthly lowerso that the condensate water willflow freely.

4. Install the piping so that the drainhose is at the bottom (Figure 7).

Caution• To prevent breaking of the pipe,

avoid sharp bends. Bend thepipe with a radius of curveture of100 mm. or more.

• If the pipe is bent repeatedly at thesame place, it will break.

• Do not remove the flare nutsfrom the indoor unit pipe untilimmediately before connectingthe outdoor connection piping.

5. After passing the indoor pipingand drain hose through the wallhole, hang the indoor unit on thehooks at the top and bottom ofthe wall bracket.

6. Check to insure that: (Ref.Figure 10).

• The top and bottom hooks arehooked firmly and the indoor unitdoes not move to the front andrear or left and right.

• The indoor unit is accuratelypositioned horizontally andvertically.

• The drain hose is at the bottomof the wall hole pipe.

Indoor Unit WiringBoth of the cable wires should beconnect from the terminal blockof indoor unit (Figure 11).

• The appliance shall be installed inaccordance with national wiringregulation.

• Means for disconnection from thesupply having a contact separationof at least 3 mm. in all poles mustbe incorporated in the field wiring.

A good flare should have thefollowing characteristics:- Inside surface is glossy and

smooth.- Edge is smooth.- Tapered sides are of uniform

length.

Bending5. When bending the tube, be careful

not to crush it. To prevent crushingof the tube, bend it gently and donot bend the tube at a radiuscurvature of less than 100 mm.

3. Remove the flare nut from theunit and be sure to mount it onthe copper tube.

4. Make a flare at the end of coppertube with a flare tool (Figure 14,15).

Outdoor Unit Installation1. Install the unit mounting pads

(4 places) into the bottom channelsby tapping gently with a plastic orrubber tipped hammer.

2. Set the unit on a strong surfacesuch as one made of concrete tominimize shock and vibration andto locate the unit securely.

3. Do not set the unit directly on the

ground.

Connecting the Unit withFlaring Procedure.Flaring (If piping is procured or cut atthe site).

1. Cut the copper tube to therequired length with a tube cutter.It is recommended to cut approx.30-50 cm. longer than the tubinglength you estimate.

2. Hold each pipe downward whencutting and remove burrs at theend of the copper tube with a tubereamer or file. This process isimportant and should be donecarefully to make a good flare(Figure 12 and Figure 13).

6. If the copper tube is bent or pulledtoo often, it will become stiff. Donot bend the pipe more than threetimes at one place.

Cautions before ConnectingTubes Tightly7. Be sure to apply a sealing cap

or water-proof tape to preventdust or water from getting intothe tubes before they are used.

8. Be sure to apply refrigerantlubricant to the matchingsurfaces of the flare and unionbefore connecting them together.This is effective for reducing gasleaks (Figure 16).

Union Flare nut

Connection9. For proper connection, align the

union tube and flare tube straightwith each other, then screw in theflare nut lightly at first to obtain asmooth match (Figure 17).

When reaming, hold the tube enddownward and be sure that nocopper scraps fall into the tube.

10. Tighten the flare nut to thespecified tightening torque withtorque wrench and adjustablewrench (Figure 18).

11. Repeat the process above for theremaining line.

Remote Control InstallationLocate and attach the wirelessremote control as follows:1. Do not place the control and the

remote control near heat sourcesor expose to the direct rays of thesun.

2. Do not expose the control to theindoor unit’s supply air stream.

3. Do not place in a confined space.4. Attach the remote control holder

as shown in Figure 19.

Evacuation and RefrigerantCharge1. Air Evacuation and Charging

1. Remove the cap and connect thegauge manifold and the vacuumpump to the charging port usingthe service hoses (Figure 20).

2. Pump the indoor unit and theconnecting pipes until thepressure in them lowers to below1.5 mmHg of vacuum.

3. Stop the vacuum pump and closethe gauge manifold valve.

4. Remove the blanking caps andfully open the service valves witha hexagon wrench (Torque: 70to 90 kgf - cm).

Caution• FREON GAS “R22” ONLY• Always evacuate air from the piping

before adding refrigerant.• Add refrigerant through the

charging valve after the completionof removing the blanking caps andfully open the service valves.

Gas Leakage InspectionAfter charging with refrigerant, checkthe joints for gas leakage with gas leakdetector or a soap bubble solution.

Outdoor Unit Wiring1. Remove the outdoor unit terminal

cover (Figure 21).2. Route the connection cable through

the cable entry brushing and up tothe terminal block.

3. Insert the end of the cable wiresinto the terminal block connectorsas shown on the unit wiringdiagram (Figure 11).

4. Tighten the terminal blockconnector screws.(Torque: 7-12 kgf-cm).

• The appliance shall be installed inaccordance with national wiringregulation.

Caution• The connector cable wires must be

connected such that terminalnumbers on the indoor unit matchthose on the terminal block of theoutdoor unit (Figure 11).

• Insert the connection cable wiresinto the terminal block firmly.Incorrect insertion may cause asafety problem.

5. Replace the outdoor unit terminalcover.
