15 English
Beware the fan running when open the front panel.
The fan may continue rotation after the system stop the operation.
(8) When the required amount of refrigerant is charged, close the
valve A (See figure 31) (*8) and push the RETURN button (BS3)
once. And then go to procedure (9).
(9) Push the MODE button (BS1) once, and the charging is complete.
Notes (*1)~(*9)
(*1) Lead the refrigerant charge hose etc from the pipe intake.
All front panels must be closed at the procedure (7).
(*2) • If you perform the refrigerant charging operation within the
refrigerant system that have the power off unit, the operation
cannot finish properly.
Check the number of outdoor and indoor units that is powered.
For checking, see [How to check how many units are con-
nected] in chapter 11-1.
• To energize the crankcase heater, make sure to turn on for
6 hours before starting operation.
(*3) It takes about 2~10 minutes for getting stability of refrigerant state.
If the additional refrigerant is little and operation is started before
getting stability, the system can not judge the charging amount
precisely and it cause over charge.
(*4) If the TEST button (BS4) is not pushed within 5 minutes, “P2” code
will displayed in the remote controller. In this case, refer [Remote
controller cooling (or heating) mode malfunction code].
(*5) If the front panel is opened during the operation, the system can-
not operate properly.
(*6) If you leave the system without connecting the refrigerant tank or
opening the valve A for 30 minutes or more, the system stop oper-
ation and “P2” code are displayed in remote controller.
In this case, refer [Remote controller cooling (or heating) mode
malfunction code].
(*7) Depending on the situation of operation such as the charging
amount is little, the “PE” code may not be displayed and the “P9”
code may be displayed.
(*8) Always close the valve A and take the tank off.
The refrigerant charge port of this unit have electric expansion
valve and the valve are closed when charging is finished. However,
the valve will opened when ather operation (Check operation,
nomal operation, etc.). If you leave the tank connected, the refrig-
erant will charged and it cause over charge.

6.
After completing the additional refrigerant charging, record the
charging amount on the accessory “REQUEST FOR THE INDI-
CATON” label (Installation records) and adhere it to the back side
of the front panel. Also, record the factory charged refrigerant
amount, additional refrigerant amount in the field and total refrig-
erant amount of the system to “ADDITIONAL REF. CHARGE”
label and adhere in the proximity of the refrigerant charge port.
About “ADDITIONAL REF. CHARGE” label, refer to [Important
information regarding the refrigerant used] in “1-2 Special notice
of product”.
11-2-2 Procedure of check operation
• Check operation perform the following work. Do the check opera-
tion following below.
Otherwise, malfunction code “U3” will be displayed in the remote
controller and nomal operation can not be carried out.
Check of shutoff valve opening
Check of miswiring
Judgment of piping length
Check of refrigerant overcharge
Note
• Check operation can not carried out at outdoor temp. less than –5°C.
Perform the check operation at day or time that outdoor temp. is –5°C
or more.
[Check Operation Procedure]
(1) Close the EL. COMPO. BOX (1) lid and all front panels except as
the side of the EL. COMPO. BOX (1) and turn on the power to the
outdoor unit and all connected BS, indoor units. (Be sure to turn
the power on at least 6 hours before operation in order to have
power running to the crank case heater.)
(2) Make the onsite settings as needed using the push button (BS1-
BS5) on the outdoor unit PC-board (A1P) with the power on. (See
“12. ONSITE SETTINGS”)
(3) Perform the check operation following the Check Operation Method of
the [Service Precautions] label (lower) on the EL. COMPO. BOX (1)
lid (see figure 32). The system operation for about 40~60 minutes and
automatically stops the check operation.
If the malfunction code is not displayed in the remote controller after
the system stop, check operation is completed. Normal operation will
be possible after 5 minutes. If the malfunction code is displayed in the
remote controller, correct the malfunction following [Remote controller
displays malfunction code] and perform the check operation again.

The refrigerant tank is empty. Close the valve A and
replace empty tank to the new tank. After changing the
tank, open the valve A again.
Beware the fan running. The outdoor unit does not
stop operation.
P8
Close the valve A immediately, and restart the operation
from procedure (3).
P2
Operation is interrupted. Close the
valve A immedeately and check the
below items.
• Check if HP/LP gas pipe, suc-
tion gas pipe or liquid pipe
shutoff valve is opened.
• Check the refrigerant tank is
connected and the valve A
was opend.
• Check if the air inlet and outlet
of the indoor unit are not
closed by an obstruction.
After correcting the
abnormality, restart
the operation from
procedure (3).
∗
Operation is stoped abnormally.
Close the valve A immediately. Con-
firm the malfunction code and cor-
rect the abnormality following the
[Remote controller displays mal-
function code] in chapter 11-2-2.
P9
Charging is finished. Close the valve A and take the refrig-
erant tank off.

P8
Close the valve A immediately and push the TEST button
(BS4) once. And restart from procedure (7) of “In case of
heating mode”.
P2
Operation is interrupted. Close the valve A immedeately
and check the below items.
• Check if HP/LP gas pipe, suction gas pipe or liquid
pipe shutoff valve is opened.
• Check the refrigerant tank is connected and the valve
A was opend.
• Check if the air inlet and outlet of the indoor unit are
not closed by an obstruction.
