How to clean the drain strainer
The drain strainer clears dirt out of the drain water and prevents the
piping from clogging. However, if the strainer mesh gets clogged,
water may overflow. Remove and wash the mesh with water before
and after seasons when the unit is in use and once during those
seasons.
1 Remove the drain strainer in the drip pan under the drain pan
and wash off any dirt that may have accumulated.
2 Return the drain strainer to its previous position so that the
strainer does not leak.
(A) Using a vacuum cleaner (B) Washing with water
NOTE
Do not use gasoline, benzene, thinner, polishing
powder, liquid insecticide. It may cause discolouring or
warping.
Do not let the indoor unit get wet. It may cause an
electric shock or a fire.
NOTE
Be sure to install the discharge grill in the same way as
before removal. Otherwise the air flow direction will be
avers with a short circuit of air or a wrong spreading of
air as possible result. Refer to the figures mentioned in
the note on page 2.
