(3) Make settings for airflow automatic adjustment. After
setting the air conditioner to “fan operation mode”,
stop the air conditioner, go to “FIELD SET MODE”,
select “MODE NO. 21” (11 in the case of group set-
tings), set the setting “FIRST CODE NO.” to 7, and
set the setting “SECOND CODE NO.” to 03.
Return to normal mode after these settings, and
press the ON/OFF OPERATION button. Then the
operation lamp will be lit and the air conditioner will
go into fan operation for airflow automatic adjust-
ment. Do not adjust the throttles of the air outlets or
inlets during automatic adjustment of the air condi-
tioner. After the air conditioner runs approximately
one to eight minutes, the air conditioner will finish air-
flow adjustment automatically, the operation lamp will
be turned OFF, and the air conditioner will come to a
stop.

(4) After the air conditioner stops operating, check with
“MODE NO. 21” on an indoor unit basis that 02 is set
for the “SECOND CODE NO.” in Table 3. If the air
conditioner does not stop operating automatically or
the “SECOND CODE NO.” is not 02, repeat steps
from (3). If the outdoor unit is not turned ON, U4 or
UH as explained in Table 7 will be displayed. This dis-
play is not problematic, because this function is set
for the indoor unit. Continue setting the function.
After setting this function, be sure to turn ON the out-
door unit before the test operation of the outdoor unit.
If any other error is displayed, refer to Table 7 and
the operation manual provided with the outdoor unit
and check the defective point.
• If there is any change after airflow adjustment in the
ventilation paths (e.g., the duct and air outlet), be sure to
make airflow auto adjustment again.
• Consult your Daikin representative if there is any change in
the ventilation paths (e.g., the duct and air outlet) after the
test operation of the outdoor unit is finished or the air
conditioner is moved to another place.
(b) Select External Static Pressure with Remote Controller
Check that 01 (OFF) is set for the “SECOND CODE
NO.” in “MODE NO. 21” for airflow adjustment on an
indoor unit basis in Table 3. The “SECOND CODE NO.”
is set to 01 (OFF) at factory set. Change the “SECOND
CODE NO.” as shown in Table 4 according to the exter-
nal static pressure of the duct to be connected.
(1) The “SECOND CODE NO.” is set to 07 (an external
static pressure of 0.4 inWG) at factory set. (FXMQ18
· 24 · 30 · 36 · 48PVJU)
The “SECOND CODE NO.” is set to 02 (an external
static pressure of 0.2 inWG) at factory set. (FXMQ07
· 09 · 12PVJU)
*1 The FXMQ18 · 24 · 30 · 36 · 48PVJU cannot be set to
0.12 inWG.
*2 The FXMQ07 · 09 · 12PVJU cannot be set to 0.44-0.80
inWG.

• Keep in mind that a shortage of airflow quantity or water
leakage will result because the air conditioner will be
operated outside the rated range of airflow quantity if the
external static pressure is wrongly set.
3. Filter Sign Settings
• The remote controller is provided with an LCD that tells
the time of air filter cleaning.
• If the air conditioner is used in places with excessive
dust, change the “SECOND CODE NO.” as shown in
Tab l e 5 .
The “SECOND CODE NO.” is set to 01 (standard) at
factory set.
