1. INDOOR UNIT

(1) The inlet and outlet ports should not be obstructed , the air should be able to blow all over the room.(2) Do not install the unit where it will be exposed to direct sunlight.(3) Install the unit where connection to the outdoor unit is easy.(4) Install the unit where the drain pipe can be easily installed.(5) Take servicing, etc. into consideration and leave the spaces shown below. Also install the unit where the fi lter can be

removed.

Decide the mounting position together with the customer as follows:

2. OUTDOOR UNIT

(1) If possible, do not install the unit where it will be exposed to direct sunlight. (If necessary, install a blind that does not interfere with the air fl ow.

(2) Install de outdoor unit in a place where it will be free from being dirty or getting by rain as much as possible.(3) During heating operation, drain water fl ows from the outdoor unit. Therefore, install the outdoor unit in a place where

the drain water fl ow will not be obstructed. (Heat pump model only).(4) Do not place animals and plants in the path of the warm air.(5) Take the air conditioner weight into account and select a place where noise and vibration are less.(6) Select a place so that the warm air and noise from the air conditioner do not disturb neighbours.(7) Provide the space so that the air fl ow is not blocked. Also for effi cient operation, leave open three or the four directions

front, rear and both sides.

INSTALLATION PROCEDUREInstall the air conditioner as follow:

INDOOR UNIT INSTALLATION

The piping can be connected in the fi ve directions indi-cated by 1,2,3,4, and 5 shown below. When the piping is connected in direction 2 and 5, cut along the piping groove in the side of the front cabinet with a hacksaw. When connecting the piping in direction 3, cut a notch in the thin wall at the bottom of the front cabinet.

2. CUTTING THE HOLE IN THE WALL FOR THE CONNECTING PIPING

(1) Cut a 80 mm. diameter hole in the wall at the position shown below.

(2) When cutting the wall hole at the inside of the installa tion frame, cut the hole at least 10 mm. below or more.

(3) Cut the hole so that the outside end is lower than (5 to 10 mm.) the inside end.

(4) Always align the center of the wall hole. If misaligned, water leakage will occur.

(5) Cut the wall pipe to match the wall thickness and stick the pipe through the hole.

(6) For 5 left piping and 2 right piping, cut the hole a little lower so that drain water will fl ow freely.

If the wall pipe is not used, the cord intercon-necting the indoor and outdoor units may touch metal and cause electric leakage.

Install the wall hook bracket horizontally and perpendicularly.

3. FORMING THE DRAIN HOSE AND PIPE

(1) Do not remove the fl are nut from the indoor unit pipe until immediately before connecting the connection pipe.

(2) To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of 70 mm. Or over.

(3) If the pipe is bent repeatedly at the same place, it will break.

1. INSTALLING THE WALL HOOK BRACKET

(1) Install the wall hook bracket so that it is correctly positioned horizontally and vertically. If the wall hook bracket is tilts, water will drip to the fl oor.

(2) Install the wall hook bracket so that it is strong enough to withstand the weight of the indoor unit.

(3) Fasten the wall hook bracket to the wall with 6 or more screws through the holes near the outer edge of the bracket.

- Check that there is no rattle at the wall hook brac-ket.

- Install the indoor Unit piping in the direction of the wall hole and bind the drain hose and pipe together with vinyl tape.

- Install the piping so that the drain hose is at the bottom.

- Perform “INDOOR UNIT WIRING” (in separated sheet) before performing this piping.

- Wrap the pipes of the indoor unit that are visible from the outdoor with decorative tape.

- After passing the indoor piping and drain hose through the wall hole, hang the indoor unit on the hooks of the wall hook bracket.

4. INSTALLING THE DRAIN HOSE

- Insert the drain hose into the drain port.- For left piping and left rear piping, align the marks n the

wall hook bracket and shape the connection pipe.

- Bend the connection piping at a bend radius of 70 mm. or more and install no more than 35 mm. from the wall.

- When extending the drain hose at the indoor unit, ins-tall the drain insulation.

- Place the indoor unit drain hose behind the drain pipe.

5. INSTALLING THE INDOOR UNIT

- Hang the indoor unit from the hooks at the top of the wall hook bracket.

- Insert the spacer, etc. between the indoor unit and the wall hook bracket and separate the bottom of the indoor unit from the wall.

6. CHECK THAT:

- The top and bottom hooks are hooked fi rmly and the indoor unit does not move to the front and rear or left

and right. (Fig. 12)- The indoor unit is accurately positioned horizontally an

vertically.- When connected from the left rear, the drain hose is at

the bottom left of the wall pipe.

2- OUTDOOR UNIT INSTALLATION

- Set the unit on a strong stand, install protective rubber pieces under it.

- Do not install the unit directly on the ground, because it will cause trouble.

- Install the unit where it will not be tilted by more than 5º.

3. CHECKING THE PIPE CONNECTIONS FOR GAS LEAKING

- For both the indoor and outdoor unit sides, check the joints for gas leaking by the use of a gas leakage detec-tor without fail when the pipes are connected.

4. HEAT INSULATION ON THE PIPE JOINTS

- Put coupler heat insulator on the joints.

AIR PURGE

- Close the high pressure side valve fully.- Check if the piping connections are secure.- Check that the stems of both 3- way valves are closed

fully.- Connect the gauge manifold service hose to the char-

ging port of the 3- way valve (side with the projection of pushing in the valve core).

- Open the low pressure side valve of the gauge mani-fold fully.

- Operate the vacuum pump and start pump down.- Pump down the system for at least 15 minutes, then

check if the compound pressure gauge reads - 100kPa (- 76 cm Hg, -1bar)

- At the end of pump down, close the low pressure side gauge of the gauge manifold fully and stop the vacuum pump.

- Slowly loosen the valve stem of the 3- way valve. When the compound pressure gauge reading reaches 1- 2 kg/ cm2, retighten the valve stem and disconnect the service hose from the 3- way valve charging port.

(If the stem of the 3- way valve is opened fully before the service hose is disconnected, it may be difficult to disconnect the service hose.)

- Fully open the valve stems of both 3- way valves using a hexagon wrench. (After the valve stem begins to turn, turn it with a torque of less than 2.9 N- m (30 kgf- cm) until its stop turning.)

- Firmly tighten both 3- way valves blank cap and the charging port cap.

ADDITIONAL CHARGE

- Refrigerant suitable for a piping length of 10 m. Is char-ged in the indoor unit at the factory.

- When the piping is longer than 10 m., additional char-ging is necessary. For the additional amount, see table below:

4- OUTDOOR UNIT INSTALLATION

WARNING!(1) When moving and installing the air conditioner,

do not mix gas other than the specifi ed refrige-rant (R-22) inside the refrigerant cycle.

(2) When adding refrigerant, add the refrigerant from the charging port at the completion of work.

5- GAS LEAKAGE INSPECTION

WARNING!- After connecting the piping, check the joints for gas leakage with gas leak detector.

6- POWER

(1) The rate voltage of this product is monophase (230V/1Ph/50 Hz).(2) Use a circuit breaker an receptacle matched to the

capacity of the room air conditioner.(3) The circuit breaker is installed in the permanent wiring.

Always use circuit that can trip all the poles of the wiring and has an isolation distance of at least 3 mm. between the contacts of each pole.

(4) Perform wiring work in accordance with standards so that the room air conditioner can be operated safely and positively.

7- ELECTRICAL WIRING

(1) Connect the connection cords fi rmly to the ter-minal block. Imperfect installation may cause a fi re.

(2) If the indoor unit connection cord (to the outdoor unit) and power supply are wired incorrectly, the air conditioner may be damaged.

(3) Always connect the ground wire.
