Safety Precautions

Use power cables of sufficient current
carrying capacity and rating.

• Cables that are too small may leak, generate
heat, and cause a fire.

Do not use the product for special purposes,
such as preserving foods, works of art, etc. It
is a consumer air conditioner, not a precision
refrigeration system.

• There is risk of damage or loss of property.

Keep the unit away from children. The heat
exchanger is very sharp.

• It can cause the injury, such as cutting the finger.
Also the damaged fin may result in degradation
of capacity.

When installting the unit in a hospital, com­munication station, or similar place, provide
sufficient protection against noise.

•

The inverter equipment, private power generator,
high-frequency medical equipment, or radio com­munication equipment may cause the air condition­er to operate erroneously, or fail to operate. On the
other hand, the air conditioner may affect such
equipment by creating noise that disturbs medical
treatment or image broadcasting.

Do not install the product where it is exposed to sea wind (salt spray) directly.

• It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins,
could cause product malfunction or inefficient operation.

Safety Precautions

■ Operation

Do not use the air conditioner in special
environments.

• Oil, steam, sulfuric smoke, etc. can significantly
reduce the performance of the air conditioner or
damage its parts.

Do not block the inlet or outlet.

• It may cause failure of appliance or accident.

Make the connections securely so that the
outside force of the cablemay not be applied
to the terminals.

• Inadequate connection and fastening may gen­erate heat and cause a fire.

Be sure the installation area does not deteri­orate with age.

• If the base collapses, the air conditioner could
fall with it, causing property damage, product
failure, or personal injury.

Install and insulate the drain hose to ensure that water is drained away properly based on the
installation manual.

• A bad connection may cause water leakage.

Be very careful about product transportation.

• Only one person should not carry the product if it weighs more
than 20 kg.

• Some products use PP bands for packaging. Do not use any PP
bands for a means of transportation. It is dangerous.

• Do not touch the heat exchanger fins. Doing so may cut your
fingers.

• When transporting the Outdoor Unit, suspending it at the specified
positions on the unit base. Also support the Outdoor Unit at four
points so that it cannot slip sideways.

example, power failure). It may result in burning out of the compressor if not preheating the crank case
with the electrical heater for more than 6 hours. (In case of the outdoor temperature below 10°C)

Lifting Method

Installation Manual 21

Lifting Method

• When carrying the unit suspended, pass the ropes under the unit and use the two suspension points each at
the front and rear.

• Always lift the unit with ropes attached at four points so that impact is not applied to the unit.

• Attach the ropes to the unit at an angle of 40° or less.

Lifting method

CAUTION

Be very careful while carrying the product.

• Do not have only one person carry product if it is more than 20 kg.

• PP bands are used to pack some products. Do not use them as a mean for transportation because they

are dangerous.

• Do not touch heat exchanger fins with your bare hands. Otherwise you may get a cut in your hands.

• Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging

bag may suffocate children to death.

• When carrying in Outdoor Unit, be sure to support it at four points. Carrying in and lifting with 3-point
support may make Outdoor Unit unstable, resulting in a fall of it.

Installation

Foundation for Installation

• Fix the unit tightly with bolts as shown below so that unit will not fall down due to earthquake or gust.

• Use the H-beam support as a base support

• Noise and vibration may occur from the floor or wall since vibration is transferred through the installation

part depending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad
shall be more than 200mm).

Ensure that the corner part can be securely mounted. Otherwise, the support for
installation may be bent.

Obtain and use the M10 anchor bolt.

The corner was not properly mounted.

WAR NING

• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal injury.

• Have installation work in order to protect against a strong wind and earthquake. Any installation
deficiency may cause unit to fall down, resulting in a personal injury.

• Especially take care for support strength of the floor surface, water drain processing (processing of
water flown out from the Outdoor Unit during operation) and paths of the pipe and wiring when
making a base support.

• Don't use a tube or pipe for water drain in the base pan and perform water drain processing by
using the drain path. Water drain may not be done due to freezing of a tube or pipe.

Preparation of Piping

1) Cut the pipes and the cable.

■ Use the accessory piping kit or the pipes purchased
locally.

■ Measure the distance between the indoor and the
Outdoor Unit.

■ Cut the pipes a little longer than measured distance.

■ Cut the cable 1.5m longer than the pipe length.

2) Burrs removal

■ Completely remove all burrs from the cut cross section
of pipe/tube.

■ Put the end of the copper tube/pipe to downward direc­tion as you remove burrs in order to avoid to let burrs
drop in the tubing.

3) Flaring work

■ Carry out flaring work using flaring tool as shown below.

Exception)
Wide Art Cool(4.0kW(13,600 Btu/h): Gas pipe(5/8"),
Liquid pipe(3/8")

Firmly hold copper tube in a bar(or die) as indicated
dimension in the table above.

4) Check

■ Compare the flared work with figure below.

■ If flare is noted to be defective, cut off the flared section

and do flaring work again.

Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

Appendix

1. Form the piping according to its routing. Avoid bending and bending back the same piping point more than
three times. (This will result in hardening the pipe.)

2. After deforming the piping, align centers of the union fitting of the Indoor Unit and the piping, and tighten
them firmly with wrenches.

3. Connect pipe to the service valve or ball valve which is located below the Outdoor Unit.

4. After completing the piping connection, be sure to check if there is gas leakage in indoor and outdoor con­nection.

CAUTION

Use two wrenches and tighten with regular torque.

1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over

120°C).

2. Precautions in high humidity circumstance:

This air conditioner has been tested according to the
"ISO Conditions with Mist" and confirmed that there is
not any default. However, if it is operated for a long
time in high humid atmosphere (dew point tempera­ture: more than 23°C), water drops are liable to fall. In
this case, add heat insulation material according to
the following procedure:

• Heat insulation material to be prepared... EPDM

(Ethylene Propylene Diene Methylene)-over 120°C
the heat-resistance temperature.

• Add the insulation over 10mm thickness at high humidity environment.
