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.

Seasonal wind and cautions in winter

• Sufficient measures are required at a snow area or severe cold area in winter so that product can be operated well.

• Get ready for seasonal wind or snow in winter even in other area.

• Install a suction and discharge duct not to let in snow or rain when the product operates at outdoor temperature of less than 10°C.

• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction

hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.

• Install the outdoor unit at the higher installation console by 50cm than the average snowfall (annual average snowfall) if it is installed at the area with much snowfall.

• Where snow accumulated on the upper part of the Outdoor Unit by more than 10cm, always remove snow for operation.

1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of the

product. (If width of the frame is wider than that of the product, snow may accumulate)

2. Don't install the suction hole and discharge hole of the Outdoor Unit facing to the seasonal wind.

CAUTION

• Always apply main power of the outdoor unit during use of product

(cooling season/heating season).

Lifting Method

• Always apply power before 6 hours to heat the crank case heater where performing test run after installation of product or where operating the product after cutting the main power of the outdoor unit (for 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)

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.

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).

E F

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. Outdoor unit (Insert the cushion pad between outdoor unit and base support to ensure that

anti-vibration may be done in a wide area) Pipe and wiring space (in case of piping and wiring on the floor surface) H-Beam support Concrete base support

WARNING

• 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.

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 "KS Standard 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... Adiabatic

glass wool with thickness 10 to 20mm.

• Stick glass wool on all air conditioners that are located in ceiling atmosphere.

• In addition to the normal heat insulation (thickness: more than 8mm) for refrigerant piping (gas piping: thick

piping) and drain piping, add further 10mm to 30mm thickness material.

WARNING

After completing work, securely tighten both service ports and caps so that gas does not leak.

Refrigerant piping installation

The method of connection consists of flare connections at the Indoor Units, flange connections for the piping of the Outdoor Unit and flare connections for the liquid piping. Note that the branched sections are brazed.

WARNING

Always use extreme care to prevent the refrigerant gas (R22) from the leakage while using fire or flame. If the refrigerant gas comes in contact with the flame from any source, such as a gas stove, it breaks down and generates a poisonous gas which can cause gas poisoning. Never weld in an unventilated room. Always conduct an inspection for gas leakage after installation of the refrigerant piping has been completed.

Pipe joint (auxiliary parts): Securely perform welding by passing nitrogen through the service valve port.

Flare nut: Loose or tighten flare nut by using the wrench with both ends. Coat the flare connection part with oil for a refrigerator.

Cap: Remove caps and operate valve, etc. After operation, always reattach caps (tightening torque of valve cap: 25Nm (250kg-cm) or more).

Service port: Make the refrigerant pipe empty and use the service port for filling additional refrigerant. Always reattach caps after completing work (tightening torque of service cap: 14Nm (140kg-cm) or more).

Liquid pipe Gas pipe Elbow joint: Elbow welding (Non-acid welding in welding)

Cautions in pipe connection/valve operation

Open status when both the pipe and the valve are in a straight line.

Cut both the pipe and the valve with a cutter to suit the length (Don't cut the length of less than 70mm)

Connection of High/Low Pressure Common pipe

1. For the High/Low Pressure Common pipe, connect both Main Outdoor Unit and Sub (1, 2) Outdoor Unit to the pipe by using elbows supplied field.

2. For cutting the pipe, connect the High/Low Pressure Common pipe after removing burrs, dusts and foreign materials within the pipe. Otherwise, the product may not operate due to sludge within the pipe.

3. For leakage inspection of the work part, pressurize nitrogen gas by 2.94MPa (30kgf/cm

4. Continue vacuum work after the vacuum degree reaches to 5Torr

5. Open side bar with the hex wrench.

Connect the pipe by using Gas pipe Pressure connection elbow. For installing the pipe in the front after cutting part in a saw, install the only pipe knock out hole part. For installing the pipe in side, install the whole of pipe knock out.
