• Do not place any obstacles which may cause a short circuit
of the discharged air.
• If piping length is over 10m, additional refrigerant should be
added as shown in the table.
Example:
If the unit is installed at a 12m distance, the quantity of
additional refrigerant should be 40g ...... (12 - 10) m x 20g/m =
40g

• Thoroughly study the following installation locations
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo fan, the fin of
the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain
pump malfunction, etc.
In these cases, take the following actions:
pump malfunction, 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 the cooking room to install the air conditioner in such place where it may not suck in oily
steam.
2. Avoid installing the air conditioner in such circumstances where cutting oil mist or iron powder exist especially in factories,
etc.
3. Avoid places where inflammable gas is generated, flows-in, contaminated, or leaked.
4. Avoid places where sulphurous acid gas or corrosive gas can be generated.
5. Avoid places near high frequency generators.
