SAFETY PRECAUTIONS

1. Safety precautions

Read the follow SAFETY PRECAUTIONS carefully before installation. Electrical work must be installed by a l ic en se d el ectrician. Be sure to use the correct rating of the power plug and main circu it f or t he m od el t o be i ns ta lled. Incorrect installation due to igno ri ng o f th e in st ru ction will cause harm or damage.

The seriousness is classified by the following indications.

WARNING

CAUTION

This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage to property.

The items to be followed are classified by the symbols:

Symbol with background white denotes item that is PROHIBITED from doing.

WARNING

1) Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock fire.

2) Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock fire.

3) Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall, water leakage, electrical shock fire.

4) Install at a strong and firm location which is able to withstand the set s weight. If the strength is not enough or installation is not properly done, the set will drop and cause injury.

5) For electrical work, follow the local national wiring standard, regulation and this installation instructions. An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock fire.

6) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.

8) When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.

9) Do not modify the length of the power supply cord or use of extension cord, and do not share the single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.

,

CAUTION

1) This equipment must be earthed and installed with earth leakage current breaker. It may cause electrical shock if grounding is not perfect.

2) Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire.

3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.

INDOOR AND OUTDOOR UNIT INSTALLATION

Connective pipe and drainage installation

1. Run the drain hose sloping downward. Do not install the drain hose as illustrated in Fig.7.

2. When connecting extension drain hose, insulate the connecting part of extension drain hose with a shield pipe, do not let the drain hose slack.

Connective pipe installation

1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.

2. For the rear-right-hand and rear-left-hand piping, install the piping as shown in Fig.10.

3. Fix the end of the connective pipe. (Refer to Tightening Connection in REFRIGERANT PIPING CONNECTION)

Piping and w rapping

Bundle the tubing, connecting cable, and drain hose with tape securely, evenly as shown in Fig.11. Because the condensed water from rear of the indoor unit is gathered in ponding box and is piped out of room. Do not put anything else in the box.

Do not block water flow by a rise.

Air purging

Air and moisture in the refrig er an t sy st em h av e undesirable effects as indicated below:

● Pressure in the system rises.

● Operating current rises.

● Cooling or heating efficiency drops.

● Moisture in the refrigerant circ ui t ma y fr ee ze a nd b lock capillary tubing.

● Water may lead to corrosion of parts in the refrigeration system.

Therefore, the indoor unit and tub in g be tw ee n th e in door and outdoor unit must be leak tested and evacuated to remove an y no nc on de nsables and moisture from the system.

Air purging w ith vacuum pump

Preparation Check that each tube(both liqu id a nd g as s id e tu be s) between the indoor and outdoor units have been properly con ne ct ed a nd a ll w iring for the test run has been completed. Remove the service valve caps fro m bo th t he g as a nd t he l iq uid side on the outdoor unit. Note that both the liquid and the gas side ser vi ce v al ve s on the outdoor unit are kept closed at this stage.

5. Electrical installation

Safety standards

- The supply voltage must be within a range of 90% to 110% of nominal value.

- The thermal circuit breaker and breaker should be 1.5 times the nominal consumption.

- All installation and wiring must comply with local and national average and the installation should be performed by qualified personnel.

- The minimum section of wiring should be as follows according to consumption.

Connect the cable to the outdoor unit

1. Remove the electrical control board cover from the outdoor unit by loosening the screw as shown in figure.

2. Connect the connective cables to the terminals as identified with their respective matched numbers on the terminal block of indoor and outdoor units.

3. Secure the cable onto the control board with the cord clamp.

4. To prevent the ingress of water, from a loop of the connective cable as illustrated in the installation diagram of indoor and outdoor units.

5. Insulate unused cords (conductors) with PVC-tape.Process them so they do not touch any electrical or metal parts.
