• 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.

Indoor Unit Drain Piping

- Drain piping must have down-slope (1/50 to

1/100): be sure not to provide up-and-down slope to prevent reversal flow.

- During drain piping connection, be careful

not to exert extra force on the drain port on the indoor unit.

- The outside diameter of the drain connection

on the indoor unit is 32mm(1-1/4 inch).

- Be sure to execute heat insulation on the

drain piping.

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings

Heat insulation material: Polyethylene foam with thickness more than 8 mm.

Drain test The air conditioner uses a drain pump to drain

water. Use the following procedure to test the drain pump operation:

- 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.

- Be sure to check the drain pump for normal operating and noise when electrical wiring is complete.

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

CAUTION

The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water.

CAUTION

• Drain line must be angled down to ensure gravity drainage.

• Minimum thickness of the insulation for the connecting pipe shall be 19mm(3/4 inch).

The unit must be horizontal or declined to the drain hose connected when finished installation.

Flaring work

Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

1 Cut the pipes

- Use the accessory piping kit or the pipes purchased locally.

- Measure the distance between the indoor and the outdoor unit.

- Cut the pipes a little longer than measured distance.

- Cut the cable 1.5m(4.9ft) longer than the pipe length.

2 Burrs removal

- Completely remove all burrs from the cut cross section of pipe/tube.

- Put the end of the copper tube/pipe to downward direction as you remove burrs in order to avoid to let burrs drop in the tubing.

3 Putting nut on

- Remove flare nuts attached to indoor and outdoor units, than put them on pipe/tube having completed burr removal. (Not possible to put them on after flaring work)

4 Flaring work

- Carry out flaring work using flaring tool as shown below.

5 Check

- Compare the flared work with figure.

- If flare is noted to be defective, cut off the flared section and do flaring work again.

Firmly hold copper tube in a bar(or die) as indicated dimension in the table above.

- Until the connection is completed, the plumbing pipe entrance should be strictly controlled.

- Stop plumbing at rainy day.

- Pipe entrance should be taken side or bottom.

- When removal burr after cutting pipe, pipe entrance should be taken down.

- Pipe entrance should be fitted cap when pass through the walls.

- No dust in the pipe.

- Until the connection is completed, the plumbing pipe entrance should be strictly controlled.

- Pipe entrance should be taken side or bottom.

- Airtightness test should be.

- Brazing operations to comply with standards.

- Flare to comply with standards.

- Flange connections to comply with standards.

Plumbing materials and storage methods

Pipe must be able to obtain the specified thickness and should be used with low impurities. Also when handling storage, pipe must be careful to prevent a fracture, deformity and wound. Should not be mixed with contaminations such as dust, moisture.

Refrigerant piping on three principles

ENGLISH

Nitrogen substitution method

Welding, as when heating without nitrogen substitution a large amount of the oxide film is formed on the internal piping.

The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor.

It prevents normal operation of the compressor. In order to avoid this problem, Welding should be done after replacing air by nitrogen gas. When welding plumbing pipe, the work is required.

◆How to work

CAUTION

1. Always use the nitrogen.(not use oxygen, carbon dioxide, and a Chevron gas): Please use the following nitrogen pressure 0.02MPa Oxygen --------- Promotes oxidative degradation of refrigerant oil. Because it is flammable, it is strictly prohibited to use Carbon dioxide --- Degrade the drying characteristics of gas Chevron Gas ---- Toxic gas occurs when exposed to direct flame.

2. Always use a pressure reducing valve.

3. Please do not use commercially available antioxidant. The residual material seems to be the oxide scale is observed. In fact, due to the organic acids generated by oxidation of the alcohol contained in the anti-oxidants, ants nest corrosion occurs. (causes of organic acid ’ alcohol + copper + water + temperature)

Precautions when laying power wiring

- For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal block.

- Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head will strip the head and make proper tighterning impossible.

- Over-tightening the terminal screws may break them.

Use round pressure terminals for connections to the power terminal block.

When none are available, follow the instructions below.

- Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause abnormal heat.)

- When connecting wiring which is the same thickness, do as shown in the figure below.

Round pressure terminal

Power wire

CAUTION

The power connecting cable between the outdoor and indoor units must comply with the following specifications: NRTL Recognized (for example, UL or ETL recognized and CSA certified).

AWG 14/4 is the minimum recommended wire size, however, the selected conductors must comply with local codes and be suitable for installation in wet locations.

If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer of its service agent. When the connection line between the indoor unit and outdooor unit and outdoor unit is over 1.57inch, connect the telecommunication line and power line separately.

NOTE

Use connection cable NRTL(UL, ETL, CAS…) listed and stranded copper(4) THHN conductors, sunlight (UV) resistant ROHS compliant PVC jacket 600V direct burial listed, approved for wet conditions. Temperature rated for – 20°C(-4°F) to 90°C(194°F). And this cable should be enclosed in conduit.

• Be sure to comply with local and national codes while running the wire from the indoor unit to the outdoor unit(size of wire and wiring method, etc).

• Every wire must be connected firmly.

• No wire should be allowed to touch refrigerant tubing, the compressor or any moving parts.

• The communication wirings of air conditioner should be separate and isolated from external device’s electric wiring such as computers, elevator, radio & Television broadcasting facilities, as well as medical imaging offices.

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 LCD. display. For proper display of the remote controller LCD's, the remote controller should be installed properly as shown in Fig.1. (The standard height is 4~5 ft (1.2~1.5 m) from floor level.)
