• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

INSTALLATION OF INDOOR

Drain test

- Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end.

- Feed water to the flexible drain hose and check the piping for leakage.

- When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

1 Remove the Air Filter.

2 Check the drainage.

- Spray one or two glasses of water upon the evaporator.

- Ensure that water flows drain hose of indoor unit without any leakage.

Heat insulation

1 Use the heat insulation material for the

refrigerant piping which has an excellent heat-resistance (over 120 °C).

2 Precautions in high humidity circumstance:

This air conditioner has been tested according to the "KS Standard Conditions with Mist" and confirmed that there is not any default. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23 °C), water drops are liable to fall. In this case, add heat insulation material according to the following procedure:

- Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20 mm.

- Stick glass wool on all air conditioners that are located in ceiling atmosphere.

• Specification of extension cable: 2547 1007 22# 2 core 3 shield 5 or above.

REMOTE CONTROLLER INSTALLATION

ENGLISH

Wired remote controller installation

Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature. Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by:

- Drafts, or dead spots behind doors and in corners.

- Hot or cold air from ducts.

- Radiant heat from sun or appliances.

- Concealed pipes and chimneys.

- Uncontrolled areas such as an outside wall behind the remote controller.

- This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller LED's, the remote controller should be installed properly as shown in Fig.1. (The standard height is 1.2~1.5 m from floor level.)
