(3) Make settings to adjust the air volume automatically.
After setting the operating mode to “Fan”, set the air con-
ditioner to
setting mode with the operation of the air
conditioner stopped. Select Mode No. [21] (11 in the case
of batch settings), select FIRST CODE No. “7”, and set the
SECOND CODE No. to “03”.
Return to the “Basic screen” (“Normal mode” if a wireless
remote controller is used), and press the ON/OFF button.
The operation lamp is lit, and the indoor unit will go into fan
operation for air volume automatic adjustments (at which
time, do not adjust the opening of the air outlet or inlet).
The air volume adjustments will automatically terminate
approximately 1 to 15 minutes after the indoor unit comes
into operation, and the operation lamp will be OFF and the
indoor unit will come to a stop.

(4) After the air conditioner comes to a stop, be sure to check
with Mode No. [21] per indoor unit that the above SECOND
CODE No. is “02”. If the operation of the air conditioner
does not stop automatically or the SECOND CODE No. is
not set to “02”, repeat the setting procedure from (3).
CAUTION
•
If airfl ow pathway changes, such as duct and air outlet
changes, are made after air volume adjustments, be sure to
make “Air volume automatic adjustment” again.
• If airfl ow pathway changes, such as duct and air outlet
changes, are made after
11. TEST OPERATION or air
conditioner relocation, contact your dealer.
(b) Select external static pressure with the remote controller.
Check with Mode No. [21] per indoor unit that the SECOND CODE
No. for the above “Air volume adjustment” is set to “01” (OFF).
(The SECOND CODE No. is factory set to “01” (OFF).)
Change the SECOND CODE No. by referring to the table below
according to the external static pressure of the duct to be
connected.

10. FIELD SETTING
CAUTION
Before carrying out field setting, check the items mentioned in
(1) Items to be checked after the installation work is
completed on page 3.
• Check if all the installation and piping works for the air
conditioner are completed.
•
Check that the outside panel and piping cover of the indoor
and outdoor units are closed.
< FIELD SETTING >
After turning on the power supply, carry out field setting
from the remote controller according to the installation
state.
• Carry out setting at 3 places, “Mode No.”, “FIRST CODE No.”
and “SECOND CODE No.”.
The settings shown by
in the following tables indicate
those when shipped from the factory.
•
The method of setting procedure and operation is shown in
the installation manual attached to the remote controller.
(Note) Though setting of “Mode No.” is carried out as a group,
if you intend to carry out individual setting by each
indoor unit or
confi rmation after setting, carry out
setting with the Mode No. shown in the paren thesis ( ).
• Ask your customer to keep the manual attached to the remote
controller together with the operation manual.
• Do not carry out settings other than those shown in the table.
•
Settings are performed by selecting “Mode No.”, “FIRST
CODE No.”, and “SECOND CODE No.”.
10-1 Settings for external static pressure
• Make settings in either method (a) or method (b).
(a) Make settings with Air volume automatic adjustment
function.
“Air volume automatic adjustment” function: The air volume
is adjusted to the rated air volume automatically.
CAUTION
• Be sure to check that the external static pressure is within
the
specification range before making settings. The external
static pressure will not be automatically adjusted and air
volume
insufficiency or water leakage may result if the
external static pressure is outside the range. (Refer to the
technical document for the setting range of external static
pressure.)
(1) Check that the electrical wiring and duct work have been
completed.
(If the closing damper is set midway, be sure to check that
the damper is opened. Furthermore, check that the air
passage on the suction side is provided with an air
filter
(field supply)).
(2) If air conditioner has more than one air outlet and air inlet,
be sure to make adjustments so that the air volume ratio of
each air outlet and the corresponding air inlet will conform
to the designed air volume ratio.
In that case, set the operating mode to “Fan”. (In the case
of changing the air volume, press the fan speed button on
the remote controller and change the current selection to
“High”, “Medium”, or “Low”.)
