IMPORTANT SAFETY INSTRUCTIONS

WARNING
To reduce the risk of explosion, fire, death, electric shock, injury or scalding to persons when using this product, follow basic precautions, including the following:

Children in the Household
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

Installation

• Do not install the air conditioner on an unstable surface or in a place where there is danger of it falling.
• Contact an authorized service center when installing or relocating the air conditioner.
• Install the panel and the cover of the control box safely.
• Do not install the air conditioner in a place where flammable liquids or gases such as gasoline, propane, paint thinner, etc., are stored.
• Make sure that the pipe and the power cable connecting the indoor and outdoor units are not pulled too tight when installing the air conditioner.
• Use standard circuit breaker and fuse that conform to the rating of the air conditioner.
• Do not input air or gas into the system except with the specific refrigerant.
• Use non-flammable gas (nitrogen) to check for leak and to purge air; using compressed air or flammable gas may cause fire or explosion.
• The indoor/outdoor wiring connections must be secured tightly, and the cable should be routed properly so that there is no force pulling the cable from the connection terminals. Improper or loose connections can cause heat generation or fire.
• Install dedicated electric outlet and circuit breaker before using the air conditioner.
• Do not connect the ground wire to a gas pipe, a lightning rod, or a telephone ground wire.
• Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
• Do not install the unit in potentially explosive atmospheres.

Operation

• Be sure to use only those parts listed in the service parts list. Never attempt to modify the equipment.
• Make sure that children do not climb on or hit the outdoor unit.
• Dispose of the batteries in a place where there is no danger of fire.
• Use only the refrigerant specified on the air conditioner label.
• Cut off the power supply if there is any noise, smell, or smoke coming from the air conditioner.
• Do not leave flammable substances such as gasoline, benzene, or thinner near the air conditioner.
• Contact an authorized service center when the air conditioner is submerged by flood waters.
• Do not use the air conditioner for an extended period of time in a small place without proper ventilation.
• In the event of a gas leak (such as Freon, propane gas, LP gas, etc.) ventilate sufficiently before using the air conditioner again.
• Be sure to ventilate sufficiently when the air conditioner and a heating appliance such as a heater are used simultaneously.
• Do not block the inlet or outlet of air flow.
• Do not insert hands or other objects through the air inlet or outlet while the air conditioner is operating.
• Make sure that the power cable is neither dirty, loose, nor broken.
• Never touch, operate, or repair the air conditioner with wet hands.
• Do not place any objects on the power cable.
• Do not place a heater or other heating appliances near the power cable.
• 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.
• Cut off the power supply immediately in the event of a blackout or a thunderstorm.

Guidelines for Electrical Energy Saving

This manual shall include instructions for Electrical Energy saving related to operating air conditioner by the customer as follows:

• Select the temperature which is adjusted for cooling or heating mode to be energy saving so that room temperature is at a comfortable level.

In summer
Don’t wait until the room is too hot. Turn the room air conditioner for cooling before that.
Avoid exaggeration in adjusting the temperature so that the room is very cold in the case of cooling mode because it leads to increased consumption of electrical energy as it is harmful to health.

In winter
Don’t wait until the room is too cold, Turn the air conditioner for heating before that.
Avoid exaggeration in adjusting the temperature so that the room is very hot in the case of heating mode because it leads to increased consumption of electrical energy as it is harmful to health.

• Doors, windows and any other openings shall be closed inside the conditioned room to prevent leakage of the conditioned air outside and to prevent the non-conditioned air from entering the conditioned room to maintain the air conditioner efficiency.
• Make sure that the conditioned room is not exposed to direct sunlight. In case of exposure to sunlight, set down the curtains on windows to prevent exposure to sunlight and to maintain the efficiency of the air conditioner.
• Make sure that there is no obstructing to the movement of the air conditioned out of the air conditioner or the movement of return air to the device in order to maintain the efficiency of the device and the amount of air necessary for it, so take into account the absence of curtains, furniture or any obstructions in front of your air conditioner.
• Use the healthy economic function during the sleeping time to save electrical consumption and get comfortably healthy sleep while running the air conditioner for cooling or heating.
• Ensure the regularity of the air distribution in the place to be conditioned by the correct choice for the prompt movement of the air conditioned router by the operating system cooling or heating by:
  − Using automatic Swing function for horizontal movement router to the air conditioned.
  − Using Control the movement of horizontal movement router to the air conditioned.
  − Manual adjustment of the vertical routers to the air conditioned to the left or right as needed.
  − Instruction manual for installation and maintenance of the air-conditioner.
