INSTALLING 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.

NOTE: 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, rise 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.

CONNECTION PIPE REQUIREMENT

CAUTION

Install heat insulation around both the gas and liquid pipes.

Failure to do so may cause water leaks.

Use heat insulation with heat resistance above 248 °F. (Re-

verse cycle model only)

In addition, if the humidity level at the installation location

of the refrigerant piping is expected to exceed 70%, install

heat insulation around the refrigerant piping. If the ex-

pected humidity level is 70-80%, use heat insulation that

is 15 mm (19/32") or thicker and if the expected humidity

exceeds 80%, use heat insulation that is 20 mm (3/4") or

thicker.

If heat insulation is used that is not as thick as specified,

condensation may form on the surface of the insulation.

In addition, use heat insulation with heat conductivity of

0.045 W/(m·K) or less (at 68 °F).

document.

SPECIAL PRECAUTIONS

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR

DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD

ATTEMPT TO WIRE THIS SYSTEM.

•

Do not supply power to the unit until all wiring and tubing are completed

or reconnected and checked.

•

Highly dangerous electrical voltages are used in this system. Carefully

refer to the wiring diagram and these instructions when wiring. Improper

connections and inadequate grounding can cause accidental injury or

death.

•

Ground the unit following local electrical codes.

•

Connect all wiring tightly. Loose wiring may cause overheating at con-

nection points and a possible fire hazard.

WARNING:

CAUTION:

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get

a partner to help, and bend your knees when lifting to reduce strain on

your back. Sharp edges or thin aluminum fins on the air conditioner can

cut your fingers.

When Installing...

...In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit’s weight. It

may be necessary to construct a strong wood or metal frame to provide

added support.

...In a Room

Properly insulate any tubing run inside a room to prevent “sweating” that

can cause dripping and water damage to walls and floors.

...In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level

foundation for the outdoor unit. This prevents water damage and abnor-

mal vibration.

...In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable air baffle.

...In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting

snow. Provide snow vents.

When Connecting Refrigerant Tubing

•

Keep all tubing runs as short as possible.

•

Use the flare method for connecting tubing.

•

Apply refrigerant lubricant to the matching surfaces of the flare and

union tubes before connecting them, then tighten the nut with a torque

wrench for a leak-free connection.

•

Check carefully for leaks before starting the test run.

NOTE:

Depending on the system type, liquid and gas lines may be either narrow

or wide. Therefore, to avoid confusion the refrigerant tubing for your

particular model is specified as either “small” or “large” rather than as

“liquid” or “gas”.

When Servicing

•

Turn the power OFF at the main circuit breaker panel before opening

the unit to check or repair electrical parts and wiring.

•

Keep your fingers and clothing away from any moving parts.

•

Clean up the site after you finish, remembering to check that no metal

scraps or bits of wiring have been left inside the unit being serviced.

•

After installation, explain correct operation to the customer, using the

operating manual.

This air conditioner uses new refrigerant HFC (R410A).

The basic installation work procedures are the same as conventional refrigerant models.

However, pay careful attention to the following points:

1 Since the working pressure is 1.6 times higher than that of conventional refrigerant models, some of the piping and instal-

lation and service tools are special. (See the table below.)

Especially, when replacing a conventional refrigerant model with a new refrigerant R410A model, always replace the con-

ventional piping and flare nuts with the R410A piping and flare nuts.

2 Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with con-

ventional refrigerant and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is 1/2 UNF

20 threads per inch.]

3 Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with refrigerant models. Also, when

storing the piping, securely seal the openings by pinching, taping, etc.

4 When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and

always charge from the liquid phase side whose composition is stable.

Special tools for R410A

Contents of change

Pressure is high and cannot be measured with a conventional gauge. To prevent erroneous mixing of other

refrigerants, the diameter of each port has been changed.

It is recommended the gauge with seals –0.1 to 5.3 MPa (–76 cmHg to 53 kgf/cm

) for high pressure.

–0.1 to 3.8 MPa (–76 cmHg to 38 kgf/cm

) for low pressure.

To increase pressure resistance, the hose material and base size were changed.

A conventional vacuum pump can be used by installing a vacuum pump adapter.

Copper pipes

It is necessary to use seamless copper pipes and it is desirable that the amount of

residual oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed,

deformed or discolored portion (especially on the interior surface). Otherwise, the

expansion valve or capillary tube may become blocked with contaminants.

As an air conditioner using R410A incurs pressure higher than when using

conventional refrigerant, it is necessary to choose adequate materials.

Thicknesses of copper pipes used with R410A are as shown in the table. Never

use copper pipes thinner than that in the table even when it is available on

the market.

GENERAL

This INSTALLATION INSTRUCTION SHEET briefly outlines where and

how to install the air conditioning system. Please read over the entire set

of instructions for the indoor and outdoor units and make sure all acces-

sory parts listed are with the system before beginning.

* Appearance of slender setting

1. FLARING

(1) Cut the connection pipe to the necessary length with a pipe cutter.

(2) Hold the pipe downward so that cuttings will not enter the pipe and

remove the burrs.

(3) Insert the flare nut (always use the flare nut attached to the indoor

and outdoor units respectively) onto the pipe and perform the flare

processing with a flare tool.

Use the special R410A flare tool, or the conventional flare tool.

Check if [L] is flared uniformly

and is not cracked or scratched.

CAUTION

1 To prevent breaking of the pipe, avoid sharp bends.

Bend the pipe with a radius of curvature of 150 mm (6")

or over.

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

break.

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

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

When pipes are repeatedly bend or stretched, the material will harden,

making it difficult to bend or stretch them any more. Do not bend or

stretch the pipes more than three times.

2. BENDING PIPES

To prevent gas leakage, coat the flare

surface with alkylbenzene oil (HAB).

Do not use mineral oil.

(3) When the flare nut is tightened properly by your hand, use a torque

wrench to finally tighten it.
