7.2 Protection Function

 

7.2.1 Three minutes delay at restart for compressor.

7.2.2 Anti-freezing protection at cooling or dry mode.

Anti-freezing control according to T2 (Indoor evaporator temperature).

If the evaporator pipe temperature had been lower than 1℃ for 14 minutes, the evaporator

anti-freezing protection will be activated. The compressor will keep off in the following 5 minutes

5 minutes later, if the evaporator pipe temperature is still lower than 4℃, the compressor will stay off.

Otherwise the compressor will be started and the function is cancelled.

Anti-freezing control according to TIME.

If the lasting time of compressor which is continuously running has got to 105 minutes with fan

motor operating under Med or Low speed and the indoor ambient temperature lower than 26℃, the

anti-freezing function will be activated. The compressor will keep off for 3 minutes.

Note:

If the compressor stops operation, the time will be cleared.

7.2.3 Anti-frosting protection and defect at cooling or dry mode.

3 minutes later when compressor is running, if T2 has been less than -14℃ for subsequent 3

minutes, the anti-frosting protection is activated and compressor will stop in the following 6 minutes.

After that, if the condition for de-frosting function is met again in the following 10 minutes while the compressor is operating, the unit will display ‘ Ed ’ to indicate that the unit is in the de-frost defect.

INSTALLATION

8 Installation details

8.1 Select the best location.

1. To avoid vibration and noise, make sure the unit is installed securely and firmly.

2. Install the unit where the sunlight does not shine directly on the unit. If the unit receives. direct sunlight, build an awning to shade the cabinet.

3. There should be no obstacle, such as a fence or wall, within 500mm from the back of the

ambient because it will prevent heat radiation of the condenser.

4. Restriction of outside air will greatly reduce the cooling and heating efficiency of the air

Conditioner.

5. Install the unit on a slight angle so that an condensate formed will not enter the room

(about 10mm or 1/4”bubble with level).

6. Install the unit with its bottom portion 75~1500mm above the floor level.

7. The power cord must be connected to an independent circuit. The yellow/green wire must be grounded.

Window WDF 15 Version - 0

INSTALLATIOIN

8.2 Check off installation.

¾ The setting conditions must be checked prior to initial starting. The under mentioned items are

especially important checking points when the installation is finished.

¾ Grounding wire (yellow/Green) is provided in the power cord. The wire must be grounded.

¾ Ensure that the unit is connected to a suitably rated and dedicated circuit.

¾ To avoid vibration or noise, make sure the air conditioner is installed securely.

¾ Avoid placing furniture of draperies in front of the air inlet and outlet.

8.3 How to drain.

To get the maximum cooling efficiency, the air conditioner is designed to splash the condensation water on the condenser coil.

If the splashing sound annoys you, you can provide an outside drain by using the following procedure, which may however cause a small loss of performance.

1. Slide out the chassis from the cabinet.

2. Remove the rubber plug from the body base plate.

3. Install the drain pan to the corner of the cabinet with 2 screws.

4. Connect the drain hose to the outlet on the drain pan bottom.

5. Slide the chassis into its original place in the cabinet.

INSTALLATION

8.4 How to install.

z Use iron support

The installation hole should be strong enough to support the air conditioner. If it cannot, iron support has to be used outdoors.

Iron support should be fixed on the building. z

Use sunshade board

Air conditioner should avoid anything to be dropped into it and avoid direct sunshine. If there is no cover on it, you should contact the seller for installing the sunshade board. When installing the sunshade board, don’t let it block the air

1) Remove the sticker from the front panel.

2) Put the unit into the installation hole.

— When installing the unit, it should be slanted down to the back to avoid the enlargement of noise or vibration.(Slant between 6-10mm.)

— The installation place should be strong enough to avoid the enlargement of noise or vibration.

3) Fill up sews in the cabinet with sponge or foam.
