TIPS FOR SAVING ENERGY

CAUTION

Here are some tips that will help you to minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions given below:

• Do not excessively cool indoors. This may be harmful for your health and may consume more electricity.

• Block sunlight with blinds or curtains while operating the air conditioner.

•

Keep doors or windows closed tightly while operating the air conditioner.

• Adjust the direction of the air guide vane vertically or horizontally to circulate indoor air efficiently.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

CAUTION

Installation

• Always check for gas (refrigerant) leakage after installation or repair of product.

- 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

ENVIRONMENT-FRIENDLY 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. These days the developed countries have approved it as the environment-friendly refrigerant and encouraged to use it widely to prevent environment pollution.

CAUTION

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

• 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.

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.)

• Sufficient measures are required in 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 areas.

• Install a suction and discharge duct not to let in snow or rain.

• 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 50 cm 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 10 cm, always remove snow for operation.

- 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)

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

LIFTING METHOD

• When carrying the suspended, unit 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.

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.

Ⓔ H-beam support Ⓕ Concrete support

WARNING

• Install where it can sufficiently support the weight of the outdoor unit. If the support strength is not enough, the outdoor unit may drop and hurt people.

• Install where the outdoor unit may not fall in strong wind or earthquake. If there is a fault in the supporting conditions, the outdoor unit may fall and hurt people.

• Please take extra cautions on the supporting strength of the ground, water outlet treatment(treatment of the water flowing out of the outdoor unit in operation), and the passages of the pipe and wiring, when making the ground support.

• Do not use tube or pipe for water outlet in the Base pan. Use drainage instead for water outlet. The tube or pipe may freeze and the water may not be drained.

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 200 mm).

CAUTION

• Be sure to remove the Pallet(Wood Support) of the bottom side of the outdoor unit Base Pan before fixing the bolt. It may cause the unstable state of the outdoor settlement, and may cause freezing of the heat exchanger resulting in abnormal operations.

• Be sure to remove the Pallet(Wood Support) of the bottom side of the outdoor unit before welding. Not removing Pallet(Wood Support) causes hazard of fire during welding.

Preparation of Piping

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

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.

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 10 mm thickness at high humidity environ-

ment.

CAUTION

• Always use a charge hose for service port connection.

•

After tightening the cap, check that no refrigerant leaks are present

• When loosening a flare nut, always use two wrenches in combination, When connecting the piping, always use a spanner and torque wrench in combination to tighten the flare nut.

• When connecting a flare nut, coat the flare(inner and outer faces) with oil for R410A(PVE) and hand tighten the nut 3 to 4 turns as the initial tightening.

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.

REFRIGERANT PIPING INSTALLATION

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.

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 leakage after the work.

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.)
