8.8 Cleaning and Replacement of Air Intake Filter Element

Clean or replace the air intake filter element, as
soon as possible, if the error code of an element
clogging appears on the digital monitor. Failure to
do so will result in the reduction of the A
capacity and, in the worst case, the damage of the
air intake filter element.

CAUTION
Press the STOP button and disconnect
the power before proceeding to replace
the air intake filter.
If atmospheric air contains car fumes
and soots from incinerators and boilers,
the air intake filter element will be
clogged earlier than otherwise. If this is
the case, check the atmosphere around
the A installed, and take effec-
tive measures that will enable the
A to suck the fume-less and
soot-less air. For example, provide a
suction duct or re-select a cleaner in-
stallation location.

e Wait for the pressure until it reaches to the
level of its ambient air.
r Open the front cover. Unfasten three snap-on
fittings on the air intake filter cover, and pull
the suction filter element out.
t Lightly pat the filter element to remove larger
dust, and then clean it with air-blow from in-
side.
y If the filter is heavily contaminated, immerse
it in the water solution of neutral house hold
detergent for about 30 minutes, then rinse it
well by clean water (with water pressure of
0.27 MPa or less), shake water off and dry it.
IMPORTANT
Do not reuse the filter by the above cleaning more than
5 times. If its contamination is heavy, replace it with a
new one.
After cleaning of filter element, put a lamp inside the
element and check if no damage happens to it before
reuse.
u Wipe dust or stains off of the air intake filter
housing and inside the suction filter cover.
i Push the filter element in its housing firmly as
it was before.
o Place the side with a mark "TOP" of the air in-
take filter cover to face its top, and assemble it
back to the housing correctly so that three
snap-on fittings are firmly hooked and fix the
cover to the housing.
