NOTE:

• Throughly study the following installation locations:

1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc. In these cases, take the following actions:

• Make sure that the ventilation fan for smoke-collecting

hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner.

• Make enough distance from a cooking room to install

the air conditioner in such a place where it may not suck in oil steam.

2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.

3. Avoid places where inflammable gas is generated, flows in, is stored or vented.

4. Avoid places where sulfurous acid gas or corrosive gas is generated.

5. Avoid places near high frequency generators.

1. Preparation of pipings

1) Cut the pipes and the cable.

• 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 the measured distance.

• Cut the cable 1.5m longer than the length of the pipe.

2) Remove burrs.

• Remove burrs from cut edges of pipes.

• Turn the pipe end toward down to avoid the

metal powder entering the pipe.

3) Flaring the pipes.

• Insert the flare nuts, mounted on the connection ports of both indoor and outdoor unit, onto the copper pipes. Some refrgerant gas may leak, when the flare nuts are removed from the indoor unit, as some gas is charged to prevent the inside of the pipe from rusting.

• Fit the copper pipe end into the Bar of flare tool about 0~0.5mm higher. (See illustration)

• Flare the pipe ends.

4) Tape the flaring portion to protect it from the dust or damages.

2.2 Refrigerant charge

The calculation of the additional charge should be taken in account for the length of pipe.

Caution

Regulation for refrigerant leakage(in Europe) : the amount of refrigerant leakage should satisfy the following equation for human safety.

❐ If the above equation can not be satisfied, then follow the following steps.

- Selection of air conditioning system: select one of the next

1. Effective opening part Installation

2. Reconfirmation of outdoor unit capacity and piping length

3. Reduction of the amount of refrigerant

4. 2 or more security device installation of alarm for gas leakage

- Change indoor unit type : installation position should be over 2m from the floor (Wall mounted type → Cassette type)

- Adoption of ventilation system : choose ordinary ventilation system or building ventilation system

- Limitation in piping work : design for earthquake-proof and prevention against thermal stress

3) Settlement of outdoor unit

■ Anchor the outdoor unit with a bolt and nut(ø10mm)

tightly and horizontally on a concrete or rigid mount.

■ When installing on the wall, roof or rooftop, anchor the

mounting base securely with a nail or wire assuming the influence of wind and earthquake.

■ In the case when the vibration of the unit is conveyed to

the hose, secure the unit with an anti-vibration rubber.

4) Evaluation of the performance

Operate unit for 15~20 minutes, then check the system refrigerant charge:

1. Measure the pressure of the gas side service valve.
