The piping can be connected in the

five directions indicated by 1, 2, 3, 4

and 5 in Figure 4. When the piping is

connected in direction 3, 4 or 5 cut

along the piping groove in the side or

bottom of the front cover with a saw.

1. Installing the Wall Bracket

1. Install the wall bracket so that it

is level from side to side. If the

wall bracket is tilted, condensate

water will drip to the floor.

2. Install the wall bracket so that it

is strong enough to withstand a

weight of 50 kilograms or more.

3. Fasten the wall bracket to the

wall with 6 or more screws

through the holes near the outer

edge of the bracket.

4. Check to insure that there is no

rattle of the wall bracket against

the wall.

Caution

• Always cut the wall hole uniformly

and straight when the wall pipe is

not used. If the hold center is not

aligned, condensate leakage can

occur.

• If the wall pipe is not used, the

wiring cable connecting the indoor

and outdoor units may become

frayed and cause electric current

leakage to earth.

3. Forming the Indoor Drain

Hose and Refrigerant Pipes

1. For 3 Left piping. 4 Right piping,

5 Bottom piping: Perform.

“Indoor Unit Wiring” before

performing the following steps

3.2 through 3.6.

2. Wrap the pipes of the indoor unit

that are visible from the inside

with decorative tape (Figure 7).

3. Insert the indoor unit piping into

the wall hole and bind the drain

hose and pipe together with

vinyl tape (Figure 8).

2. Cutting the Hole in the Wall

for the Connecting Piping

1. Cut a 65 mm. diameter hole in

the wall at the desired position

shown in Figure 6.

2. Cut the hole so that the outside

end is lower (5-10 mm.) than the

inside end.

3. Cut the wall pipe length to match

the wall thickness, insert it into

an accessory wall cap, fasten the

cap with vinyl tape, and insert the

pipe through the wall hole. (Wall

pipe and wall cap are procured

at the site).

4. For 3 left piping and 4 right

piping, cut the hole sligthly lower

so that the condensate water will

flow freely.

A good flare should have the

following characteristics:

- Inside surface is glossy and

smooth.

- Edge is smooth.

-Tapered sides are of uniform

length.

Bending

5. When bending the tube, be careful

not to crush it. To prevent crushing

of the tube, bend it gently and do

not bend the tube at a radius

curvature of less than 100 mm.

3. Remove the flare nut from the

unit and be sure to mount it on

the copper tube.

4. Make a flare at the end of copper

tube with a flare tool (Figure 14,15).

Outdoor Unit Installation

1. Install the unit mounting pads

(4 places) into the bottom channels

by tapping gently with a plastic or

rubber tipped hammer.

2. Set the unit on a strong surface

such as one made of concrete to

minimize shock and vibration and

to locate the unit securely.

3. Do not set the unit directly on the

ground.

Connecting the Unit with

Flaring Procedure.

Flaring (If piping is procured or cut at

the site).

1. Cut the copper tube to the

required length with a tube cutter.

It is recommended to cut approx.

30-50 cm. longer than the tubing

length you estimate.

2. Hold each pipe downward when

cutting and remove burrs at the

end of the copper tube with a tube

reamer or file. This process is

important and should be done

carefully to make a good flare

(Figure 12 and Figure 13).

too often, it will become stiff. Do

not bend the pipe more than three

times at one place.

Cautions before Connecting

Tubes Tightly

7. Be sure to apply a sealing cap

or water-proof tape to prevent

dust or water from getting into

the tubes before they are used.

8. Be sure to apply refrigerant

lubricant to the matching

surfaces of the flare and union

before connecting them together.

This is effective for reducing gas

leaks (Figure 16).
