NOTE

• Avoid using the short duct on which the air discharge grille can be completely closed, to prevent evaporator freezing.

• In order to prevent condensation forming, be sure that there is sufficient thermal insulation and no leakage of cool air

when installing the short duct.

• Keep the introduction of fresh air intake within 20% of total air flow. Also provide a chamber and use a booster fan.

Sealing Material

• It is possible to seal one of the four air discharge outlet. (sealing two or more air discharge outlet could cause a malfunction)

• Remove the front panel and insert the sealing material into the air discharge outlet on the indoor unit to seal the air outlet.

• The sealing material is the same length as the longer air discharge outlet. If it is desired to seal the shorter air discharge

outlet, cut the sealing material to shorten it.

• Push the sealing material in about 10mm beyond the bottom surface of the indoor unit so that it does not touch the air

louver. Be sure not to push the sealing material in any farther than about 10mm.
