• 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 inserting the seal material into the air discharge outlet at 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 10 mm 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 10 mm.
