below:

TIPS FOR SAVING ENERGY

• Use caution when unpacking and installing.

- Sharp edges may cause injury.

• Thickness of copper pipes used are as shown “Flaring work” Table.

- Never use copper pipes thinner than that in the table even when it is available on the market

• Do not use copper pipes having a collapsed.

- Otherwise, the expansion valve or capillary tube may become blocked with contaminants.

• For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant.

- Using of (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant

cycle (piping), and possibly result in explosion and injury.

• It is desirable that the amount of residual oil less than 40 mg/10m.

• If air enters the refrigerant system, an excessively high pressure results, causing equipment dam-

age or injury.

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

els may cause failure of product.

• Ensure that you grab the chassis when you lift the unit.

- If you lift the unit with the panel held, it may result in serious injury or product failure.

• Do not turn on the breaker or power under condition that front panel, cabinet, top cover, control box

cover are removed or opened. Otherwise, it may cause fire, electric shock, explosion or death.

• Make the connections securely so that the outside force of the cable may not be applied to the ter-

minals.

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

• After pump down, power must be turned off before removing the pipe.

- When operating this product without connecting the pipe, there will be high pressure inside the

compressor due to the entry of air, possibly causing explosion or injury.

Operation

• Do not share the outlet with other appliances.

- It will cause an electric shock or a fire due to heat generation.

• Do not use the damaged power cord.

- Otherwise, it may cause a fire or electrical shock.

• Do not modify or extend the power cable.

- Scratches or peeling insulation on the power cables may result in fire or electric shock, and should

be replaced.
