- Low refrigerant levels may cause failure of product.

• Do not install the product where the noise or hot air from the outdoor unit could damage the neighborhoods.

- It may cause a problem for your neighbors.

• Keep level even when installing the product.

- To avoid vibration or water leakage.

• Do not install the unit where combustible gas may leak.

- If the gas leaks and accumulates around the unit, an explosion may result.

• 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 re-

sult 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.

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 cable may 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.

• Safely dispose of the packing materials.

Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

Tear apart and throw away plastic packaging bags so that children may not play with them. If children play with a plastic bag which was not torn apart, they face the risk of suffocation.

• Turn on the power at least 6 hours before starting operation.

- Starting operation immediately after turning on the main power switch can re-

sult in severe damage to internal parts. Keep the power switch turned on during the operational season.

• Do not touch any of the refrigerant piping during and after operation.

- It can cause a burn or frostbite.

• Do not operate the air conditioner with the panels or guards removed.

- Rotating, hot, or high-voltage parts can cause injuries.

• Do not directly turn off the main power switch after stopping operation.

- Wait at least 5 minutes before turning off the main power switch. Otherwise it

may result in water leakage or other problems.

•

Auto-addressing should be done in condition of connecting the power of all indoor and outdoour units. Auto-addressing should also be done in case of changing the indoor unit PCB.

• Use a firm stool or ladder when cleaning or maintaining the air conditioner.

- Be careful and avoid personal injury.

• Do not insert hands or other objects through the air inlet or outlet while the air conditioner is plugged in.

- There are sharp and moving parts that could cause personal injury.

ALTERNATIVE REFRIGERANT R410A

The refrigerant R410A has the property of higher operating pressure in comparison with R22. Therefore, all materials have the characteristics of higher resisting pressure than R22 ones and this characteristic should be also considered during the installation. R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone depletion potential (ODP) of R410A is 0.

SELECT THE BEST LOCATION

Select space for installing outdoor unit, which will meet the following conditions:

• No direct thermal radiation from other heat sources

• No possibility of annoying neighbors by noise from unit

• No exposition to strong wind

• With strength which bears weight of unit

• Note that drain flows out of unit when heating

• With space for air passage and service work shown next

• Because of the possibility of fire, do not install unit to the space where generation, inflow, stagnation, and leakage of combustible gas is expected.

• Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.

• Do not use unit under any special environment where oil, steam and sulfuric gas exist.

• It is recommended to fence round the outdoor unit in order to prevent any person or animal from accessing the outdoor unit.

• If installation site is area of heavy snowfall, then the following directions should be observed.

- Make the foundation as high as possible.

- Fit a snow protection hood.

• Select installation location considering following conditions to avoid bad condition when additionally performing defrost operation.

- Install the outdoor unit at a place well ventilated and having a lot of

sunshine in case of installing the product at a place With a high humidity in winter (near beach, coast, lake, etc.) (Ex : Rooftop where there is always sunshine.)

CAUTION

• The wall thickness of the piping should comply with the relevant local and national regulations for the designed pressure 3.8MPa

• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.

• Do not place the refrigerant container under the direct rays of the sun to prevent it from exploding.

• For high-pressure refrigerant, any unapproved pipe must not be used.

• Do not heat pipes more than necessary to prevent them from softening.

• Be careful not to install wrongly to minimize economic loss because it is expensive in comparison with R22.

Insulation of shutoff valve

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.

Closing shutoff valve

1 Remove the cap and turn the valve clockwise with the hexagon

wrench.

2 Securely tighten the valve until the shaft contacts the main body seal.

3 Make sure to tighten the cap securely.

Nitrogen substitution method

Welding, as when heating without nitrogen substitution a large amount of the oxide film is formed on the internal piping.

The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor.

It prevents normal operation of the compressor. In order to avoid this problem, Welding should be done after replacing

air by nitrogen gas. When welding plumbing pipe, the work is required.

1 Always use the nitrogen.(not use oxygen, carbon dioxide, and

a Chevron gas): Please use the following nitrogen pressure

0.02MPa Oxygen – Promotes oxidative degradation of refrigerant oil. Because it is flammable, it is strictly prohibited to use Carbon dioxide – Degrade the drying characteristics of gas Chevron Gas – Toxic gas occurs when exposed to direct

flame. 2 Always use a pressure reducing valve. 3 Please do not use commercially available antioxidant.

The residual material seems to be the oxide scale is ob-

served. In fact, due to the organic acids generated by oxida-

tion of the alcohol contained in the anti-oxidants, ants nest

corrosion occurs. (causes of organic acid

→

alcohol + copper

+ water + temperature)

CAUTION

Precautions on Pipe connection / Valve operation

Pipe connection is done by connecting from the end of the pipe to the branching pipes, and the refrigerant pipe coming out of the outdoor unit is divided at the end to connect to each indoor unit. Flare connection for the indoor unit, and welding connection for the outdoor pipe and the branching parts.

- Use hexagonal wrench to open/close the valve.

CAUTION

Please block the pipe knock outs of the front and side panels after installing the pipes. (Animals or foreign objects may be brought in to damage wires.)

WARNING

• Always careful not to leak the refrigerant during welding.

• The refrigerant generates poisonous gas harmful to human body

if combusted.

• Do not perform welding in a closed space.

• Be sure to close the cap of the service port to prevent gas leak-

age after the work.
