
: OFF, ON or Blinking
(1) Open the liquid pipe, suction gas pipe and HP/LP gas pipe shutoff
valves. (The valve A~C must be closed. See figure 30.)
(2)

Close the electrical components box (1) lid and all front panel
except on the electrical components box (1) side. (*1) And turn
the power to the outdoor unit and all connected BS, indoor units.
(*2)
• After H2P stop blinking (about 12 minutes after turning on the
power), check H2P is OFF.
If H2P is ON, check the malfunction code in the remote controller
of indoor unit and correct the malfunction in accordance with
[Remote controller display malfunction code] in chapter 11-2-2.
(3) Check the LED. And push the MODE button (BS1) once if the LED
displays is not as below.
(4) Push the TEST button (BS4) once. (The LED displays will change
as below.)
(5) Hold the TEST button (BS4) down for 5 seconds or more.
(The LED displays will change as below and fan of outdoor unit will
start rotation.)
(6) When the compressor start working and the LED displays change
any state in below (*3), go to “In case of cooling mode” or “In case
of heating mode” in accordance with the LED displays.
In case of cooling mode
(7) Push the TEST button (BS4) once within 5 minutes after
procedure (5) (*4) and close the all front panels (*5).
After that, open the valve A immediately (See figure 30) (*6) and
watch the remote controller display of indoor unit.
(8) If the remote controller display shows “PE” code (*7), ready to
close the valve A.
And go to procedure (9).
If the remote controller display shows other code, close the valve A
immediately and refer to [Remote controller cooling mode
malfunction code]
Beware the fan running when open the front panel.
The fan may continue rotation after the system stop the
operation.
(9) When the compressor stop working (the fan may continue
rotation.), close the valve A immediately (*8).
And check the LED displays are as below and the remote
controller display shows “P9” code.
After checking, push the MODE button (BS1) once and the
charging is complete.
In case of heating mode
(7) Push the TEST button (BS4) once within 5 minutes after
procedure (5) (*4) and close the all front panels.
After that, open the valve A immediately (See figure 30) (*6) and
check the charged amount by measuring device.
During operation, if the remote controller display shows “P2” or
“P8” code, close the valve A immediately and refer to [Remote
controller heating mode malfunction code].
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 30) (*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)~(*8)
(*1) Lead the refrigerant charge hose etc from the pipe intake.
All front panels must be closed at the procedure (7).


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 connected]
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
cannot 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
operation 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 other operation (Check
operation, normal operation, etc.). If you leave the tank
connected, the refrigerant will charged and it cause over charge.

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.

Close the valve A immediately, and restart the operation
from procedure (3).
P2
Operation is interrupted. Close the
valve A immediately 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
opened.
• 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).
