1. SAFETY PRECAUTIONS

WARNING!

This mark indicates procedures which, if improperly performed,

might lead to the death or serious injury of the user.

CAUTION!

This mark indicates procedures which, if improperly performed,

might possibly result in personal harm to the user, or damage

to property.

WARNING

For the air conditioner to operate satisfactorily, install it as outlined in this

installation instruction sheet.

Connect the indoor unit and outdoor unit with the room air conditioner piping

and cords available from our standard parts. This installation instruction sheet

describes the correct connections using the installation set available from our

standard parts.

Installation work must be performed in accordance with national wiring

standards by authorized personnel only.

If refrigerant leaks while work is being carried out, ventilate the area. If the

refrigerant comes in contact with a ame, it produces a toxic gas.

Do not turn on the power until all installation work is complete.

During installation, make sure that the refrigerant pipe is attached rmly before

you run the compressor.

Do not operate the compressor under the condition of refrigerant piping not attached

properly with 2-way or 3-way valve open. This may cause abnormal pressure in the

refrigeration cycle that leads to breakage and even injury.

During the pump-down operation, make sure that the compressor is turned off

before you remove the refrigerant piping.

Do not remove the connection pipe while the compressor is in operation with 2-way or

3-way valve open. This may cause abnormal pressure in the refrigeration cycle that

leads to breakage and even injury.

When installing and relocating the air conditioner, do not mix gases other than

the specied refrigerant (R22) to enter the refrigerant cycle.

If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to

an abnormally high value and cause breakage, injury, etc.

•Be careful not to scratch the air conditioner when handling it.

•After installation, explain correct operation to the customer, using the operating manual.

•Let the customer keep this installation instruction sheet because it is used when the air

conditioner is serviced or moved.

•The maximum length of the piping is shown in Table 1. If the units are further apart than

this, correct operation cannot be guaranteed.

4. 3. Installing the drain pipe

CAUTION

Install the drain pipe in accordance with the instructions in this installation instruction

sheet and keep the area warm enough to prevent condensation. Problems with the

piping may lead to water leaks.

Notes: Install the drain pipe.

•Install the drain pipe with downward gradient (1/50 to 1/100) and so there are no rises or

traps in the pipe.

•Use general hard polyvinyl chloride pipe (VP25) [outside diameter 32 mm (1-1/4")] and

connect it with adhesive (polyvinyl chloride) so that there is no leakage.

•When the pipe is long, install supporters.

•Do not perform air bleeding.

•Always heat insulate the indoor side of the drain pipe.

•When desiring a high drain pipe height, raise it up to 800 mm (31") or less from the

ceiling within a range of 150 mm (6") from the body. A rise dimension over this range will

cause leakage.

1. OUTDOOR UNIT PROCESSING

(1) When the outdoor unit will be exposed to strong wind, fasten it with bolts or wire at the

four places indicated by the arrows (Fig. 21).

(2) Sincethedrainwaterowsoutoftheoutdoorunitduringheatingoperation,install

the drain pipe and connect it to an commercial 16 mm hose. (When heating when the

outdoor temperature is 0 C or less, construct so that the drain water drained from the

outdoor unit will not freeze in the drain pipe.)

(3) When installing the drain pipe, plug all the holes other than the drain pipe mounting

hole in the bottom of the outdoor unit with putty so there is no water leakage (Fig. 21).

5. 1. Flare processing

(1) Cut the connection pipe with pipe cutters so that the pipe is not deformed.

(2) Holding the pipe downward so that cuttings cannot enter the pipe and remove the

burrs.

(3) Removethearenutfromtheindoorunitpipeandoutdoorunitandassembleas

5. 2. Bending pipes

The pipes are shaped by your hands. Be careful not to collapse them.

Fig. 27

Good

Extend the pipe

by unwinding it.

Bad

Do not bend the pipes in an angle more than 90°.

Whenpipesarerepeatedlybentorstretched,thematerialwillharden,makingitdifcultto

bend or stretch them any more. Do not bend or stretch the pipes more than three times.

When bending the pipe, do not bend it as is.

The pipe will be collapsed. In this case, cut

the heat insulating pipe with a sharp cutter

as shown in Fig. 28, and bend it after expos-

ing the pipe. After bending the pipe as you

want, be sure to put the heat insulating pipe

back on the pipe, and secure it with tape.

CAUTION

To prevent breaking of the pipe, avoid sharp bends.

Bend the pipe with a radius of curvature of 150 mm or over.

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

5. 5. Installing the coupler heat insulation

After checking for gas leaks, insulate by wrapping insulation around the two parts (large

and small) of the indoor unit coupling, using the coupler heat insulation.

After installing the coupler heat insulation, wrap both ends with vinyl tape so that there is

no gap.

6. ELECTRICAL WIRING

CAUTION

Before starting work, check that power is not being supplied to the outdoor unit.

Match the terminal board numbers and connection cord colors with those of the indoor

unit side.

Erroneous wiring may cause burning of the electric parts.

Connecttheconnectioncordsandthepowersupplycordrmlytotheterminalboard.

Imperfectinstallationmaycauseare.

Always fasten the outside covering of the connection cord and the power supply cord

with cord clamps. (If the insulator is chafed, electric leakage may occur.)

Always connect the ground wire.

HOW TO CONNECT WIRING TO THE TERMINALS

For strand wiring

(1) Useringterminalswithinsulatingsleevesasshowninthegurebelowtoconnectto

the terminal block.

(2) Securely clamp the ring terminals to the wires using an appropriate tool so that the

wires do not come loose.

(3) Usethespeciedwires,connectthemsecurely,andfastenthemsothatthereisno

stress placed on the terminals.

(4) Use an appropriate screwdriver to tighten the terminal screws.

Do not use a screwdriver that is too small, otherwise, the screw heads may be

damaged and prevent the screws from being properly tightened.

(5) Do not tighten the terminal screws too much, otherwise, the screws may break.

(6) See the Table 6 for the terminal screw tightening torques.
