IMPORTANT: Points to keep in mind when using your SHARP AF-R55CX air conditioner.

• Install the air conditioner by following the installation instructions.

• Make sure the unit is the correct capacity for the area you want to cool.

• Do not modify any part of this product.

• Do not insert objects into any part of the unit.

• Push the AC power plug securely into the receptacle and make sure it is not loose.

• Use a power circuit with a proper voltage rating. Use a three-pronged grounded electrical outlet rated 125V, 60Hz, 15 amp or more, AC only. Use of an improper voltage rating power circuit can result in damage to the unit and possibly fire.

• Always use a fuse with the proper amp rating. Do not, under any circumstances, use wire, pins or other objects in place of the proper fuse.

• Use of extension cords of any kind is not recommended. If you still elect to use an extension cord, it is absolutely necessary that it be a UL Listed 3-wire grounding type appliance extension cord rated 125 Volts, 15 amp or more.

• Ventilate the room periodically during use, especially if using gas appliances.

WARNING: Improper use of the grounding plug can result in the risk of electric shock. This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

WARNING: Do not under any circumstances cut or remove the round grounding prong from this plug. If it is necessary to use an extension cord, use only a UL Listed 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord should be AC 125 Volt, 15 Amp or more.

Consult a qualified electrician or serviceman if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded. If a grounding adapter is used, make sure the receptacle box is fully grounded.

• Allow 3 minutes for the compressor to restart cooling. If you turn the air conditioner off and immediately restart it, allow three minutes for the compressor to restart cooling. There is an electronic device in the unit that keeps the compressor off for three minutes for protection.

• If a power failure occurs during use, allow 3 minutes before restarting the unit. After power is reinstated, restart the air conditioner. If the power was off for less than three minutes, be sure to wait at least three minutes before restarting the unit. If you restart the air conditioner within three minutes, a protective device in the unit may cause the compressor to shut off. This protective device will prevent cooling for about 5 minutes. Memories of previous settings will be canceled and the unit will return to each initial setting.

• Dehumidifying function. The air conditioner removes moisture from the air in your room.

• Cooling operation under low temperatures: Is your unit freezing up? The unit operates on inside and outside temperatures. Freezing can occur when the temperature is set close to 64°F and when there are low outside temperatures, especially during the night hours. At these conditions, a further temperature drop may cause the unit to freeze. Setting the unit to a higher temperature will prevent it from freezing.

• Setting the proper temperature. For optimum energy efficiency, keep the difference between the inside and outside temperature within 10°F (5°C). Do not keep the temperature setting any lower than is necessary for you to feel comfortable. Generally, 78°F to 80°F (26°C to 27°C) is a comfortable summer indoor temperature. When you turn the unit on, do not set the temperature higher than the room temperature at start up as this will not allow the compressor to cycle and maintain a comfortable room temperature.

• Avoid direct sunlight. Close blinds, drapes or shades to keep out direct sunlight during cooling operation.

• Keep the filter clean. Keeping the filter clean greatly aids efficient operation. A dirty filter blocks the flow of air, making your air conditioner work harder and less efficiently.

• Turn off unnecessary light. Your air conditioner must remove the heat produced by your lights or other heat-producing appliances. Turn off lights or appliances that are not in use.

• Install your air conditioner in a shady location. Direct sunlight on a window air conditioner increases its workload and will increase its operating cost.

• Don’t let cool air escape. Close windows and outside doors. Do not keep doors open and let hot air rush in. Improperly installed air conditioners and improperly weatherstripped doors and windows will let hot air in and the cool air out.

• Turn off air conditioner when no one is home. Use only when necessary. The fewer hours a room air conditioner is used, the lower the operating cost.

2. Use the TEMPERATURE setting buttons to set the new temperature. The new set temperature will show on the display for 5 seconds and return to the time display.

If the filter is clogged with dust, air flow will be reduced, resulting in poor cooling performance. The filter should be cleaned every 10 days. Clean the filter before starting the unit at the beginning of each cooling season or after a long period of inactivity.

1. REMOVE THE FILTER

Gently pull the filter handle to the right and slide the filter out from the unit.

2. CLEAN THE FILTER

To remove dust from the filter, use a vacuum cleaner or wash it in clean water. If the filter is very dirty, wash it with detergent and rinse carefully with clean water. Dry the filter with a soft cloth. Do not expose the filter to heat or dry it in direct sunlight.

3. RE-INSTALL THE FILTER

Align the filter behind the front panel. Grasp the filter handle and gently push the filter back into place. Never operate the unit without installing the filter, as it may result in serious damage.

To clean the front panel and cabinet, wipe with a soft, dry cloth or with a cloth moistened with a mild soap. Rinse carefully by wiping with a damp cloth and dry completely.

Avoid splashing the unit with water, as excess water can damage electrical insulation and result in danger.

Never use harsh chemicals or abrasive cleaners on any part of the unit. To avoid damage, do not use hot water (120°F / 50°C or more) when cleaning.

No, oiling of the compressor and fan motor is unnecessary. The compressor is permanently lubricated and is hermetically sealed. The fan motor is lifetime sealed and does not require oiling.

If your SHARP AF-R55CX does not operate, please check the following:

• Is the unit plugged in or is the plug loose?

• Is the fuse blown or the circuit breaker tripped?

• Did you restart the unit within 3 minutes after a power failure? If the power was off for less than 3 minutes, and you restarted the air conditioner within 3 minutes, a protective device may cause the compressor to shut off, preventing cooling for about 5 minutes.

If your SHARP AF-R55CX is not cooling properly, check these points:

• Is the SELECTOR set to fan only (HIGH FAN, MED FAN, LOW FAN) mode? Cooling will not take place in the fan only mode. Change the SELECTOR setting.

• Is the filter clogged with dust? A dirty filter can cause the cooling coils to freeze. If this happens, clean the filter and replace. Run the air conditioner on the MED FAN setting until all ice dissipates.

• Is the temperature set properly? If your room is too warm, adjust the temperature setting lower. If your room is too cool, adjust the temperature setting higher.

• Is the window exposed to direct sunlight? Close curtains or blinds to minimize solar energy heating the room.

• Are the windows or doors open? Close all windows and doors for maximum cooling.

If a power failure occurs while the ON or OFF TIMER is set, the TIMER setting will be cancelled and will not resume even after the power is reinstated. This is the normal operation for this unit.

Yes, this is normal. Water will collect in the bottom tray of the unit. Water condenses on the evaporator coil at the front of the unit and is channeled to the rear where it is picked up by the condenser fan. The water is blown onto the condenser coil fins and this creates a “splashing” noise which is normal. If excess water builds up in this tray it will drain outside through a grooved channel in the tray.

• The operating sound may seem rather loud for 2 to 3 minutes when the unit is first turned on. This is the sound of the compressor’s start-up and is normal.

• A soft, swishing noise can be heard immediately after the unit is turned on or off, and also during operation. This is the sound of the refrigerant flowing inside the unit.

If the unit is not responding to the remote control, please check the following:

• Check the remote control batteries. Replace if necessary.

• Try to send the signal again with the remote control pointed directly at the unit’s receiver window.

• Check whether the remote control batteries are installed with the polarities properly aligned.
