(1) Check that power supply wiring to the air conditioner
is completed along with duct installation. If a closing
damper is installed in the air-conditioning system,
make sure that the closing damper is opened. Fur-
thermore, check that the air filter as a field supply is
attached to the air passage on the suction side.
(2) If there are a number of air outlets and inlets, adjust the
throttles so that the airflow rate of each air outlet and
inlet will coincide with the designed airflow rate. At that
time, operate the air conditioner in FAN operation mode.
To change the airflow rate, press and set the airflow
adjustment button of the remote controller to HH, H, or L.
(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 adjustment. Do not
adjust the throttles of the air outlets or inlets during
automatic adjustment of the air conditioner. After the
air conditioner runs approximately one to eight min-
utes, the air conditioner will finish airflow adjustment
automatically, the operation lamp will be turned OFF,
and the air conditioner will come to a stop.
Table 3
(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 con-
ditioner 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 9 will be displayed. This display is
not problematic, because this function is set for the
indoor unit. Continue setting the function. After set-
ting this function, be sure to turn ON the outdoor unit
before the test operation of the outdoor unit. If any
other error is displayed, refer to Table 9 and the oper-
ation manual provided with the outdoor unit and
check the defective point.
CAUTION
• If there is any change after airflow adjustment in the ventila-
tion paths (e.g., the duct and air outlet), be sure to make air-
flow 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 external static pres-
sure of the duct to be connected.
(1) The SECOND CODE NO. is set to 07 (an external
static pressure of 0.40 inWG (100 Pa)) at factory set.
(FXMQ15 · 18 · 24 · 30 · 36 · 48 · 54PBVJU)
The SECOND CODE NO. is set to 02 (an external
static pressure of 0.20 inWG (50 Pa)) at factory set.
(FXMQ07 · 09 · 12PBVJU)
*1 The FXMQ15 · 18 · 24 · 30 · 36 · 48PBVJU cannot
be set to 0.12 inWG (30 Pa).
*2 The FXMQ07 · 09 · 12PBVJU cannot be set to
0.44-0.80 inWG (110-200 Pa).
*3 The FXMQ54PBVJU cannot be set to 0.12 inWG
(30 Pa) and 0.60-0.80 inWG (150-200 Pa).
Table 4
CAUTION
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 Table 5.
The SECOND CODE NO. is set to 01 (standard) at fac-
tory set.
