1. Precautions

1.Warning: Prior to repair, disconnect the power cord from the circuit breaker.

2.Use proper parts: Use only exact replacement parts. (Also, we recommend replacing parts rather than repairing them.)

3.Use the proper tools: Use the proper tools and test equipment, and know how to use equipment may cause problems laterintermittent contact, for example.

4.Power Cord: Prior to repair, check the power cord and replace it if necessary.

5.Avoid using an extension cord, and avoid tapping into a power cord. This practice may result in malfunction or fire.

6.After completing repairs and reassembly, check the insulation resistance.

Procedure: Prior to applying power, measure the resistance between the power cord and the ground terminal. The resistance must be greater than 30 megaohms.

7.Make sure that the grounds are adequate.

8.Make sure that the installation conditions are satisfactory.

Relocate the unit if necessary.

9.Keep children away from the unit while it is being repaired.

10.Be sure to clean the unit and its surrounding area.

2.Make sure that you install the unit in an area that allow good air handling. The installation area must be able to endure vibration from the unit.

3.Make sure that you install the unit away from heat or vapor.

4.Make sure that you install the unit in an area which is cool and has adequate space.

5.Make sure that you install the unit in an area away from TVs, audio units, cordless phones, fluorescent lighting fixtures and other electrical appliances (obtain a clearance of at least one meter).

6.Make sure that you install the unit in an area which provides easy drainage for condensed water.

7.Make sure that you install the unit in an area not exposed to rain or direct sunlight.

(Install a separate sunblind if exposed to direct sunlight.)

8.Make sure that you install the unit in an area allowing good air movement. Do not install it in a space that would cause noise amplification of noise.

9.Fix the unit firmly if mounted in a high place.

3-2Function Description

3-2-1Cooling operation mode

The compressor is turned on and off according to the ambient temperature and set temperature.

1)Compressor on and off control

Compressor on and off control according to the ambient temperature

*The compressor is turned off when "ambient temperature = set temperature

*The compressor is turned on when "ambient temperature = set temperature +1˚C"

2)Default value after power reset set temperature = 75˚F

Fan speed = High

3) Set temperature indicating (setting) range : 1˚F interval from 64˚F to 86˚F.

3-2-2Fan operation mode

1)If "Fan operation mode" signal is received from remocon or panel.

the compressor is immediately turned off and only fan motor is operated at set blowing speed.

it changes such as "High Med Low High"( if Fan speed is selected).

2)The initial Fan motor speed is set to "High".

3)The set temperature can not be indicated and set.

3-2-3Energy saver operation mode

*If the compressor turn off at the cooling operation, the fan motor turn off after operation during the fixation time only, and operation that energy saver by turn off the fixation time only, and operation that energy saver by turn off the motor continuously before the condition of the compressor on.

*The fan motor is not operated at flow wind operation.

*Energy saver operation specification at the cooling operation.

1)Fan motor control in compressor on : operate with setting wind speed

2)Fan motor control in compressor off : After compressor off, the fan motor is operated breeze for 2 minutes and then it turn off.

3)After the fan motor off, the compressor and fan motor is operated normally when the compressor on.

Installation and Operating Instructions

3-2-4Sleep operation mode

1)Enable to sleep operation only when cooling operation.

2)First, 7-SEGLED DISPLAY "SLEEP" while 15 second, Second,7-SEGLED DISPLAY "8Hr" And, automatically SET OFF after operated while 8 Hour

3)If sleep operation, setting Temperature rise 1˚C after 1 Hour

4)ON TIMER operation, not operation, ENERGY SAVER operation, not sleep operation.

3-2-5Dry operation mode

If the atmosphere in the room is very humid or damp,use this operation mode. It can remove excess humidity without lowering the room temperature too much.

1) The quantity of air is adjusted automatically.
