(2)
If necessary, set the field setting by using the dip switch on the
outdoor unit PC-board (A1P).
(For how to set, see “12-1 Onsite Settings With the Power Off)
(3)
Close the EL. COMPO. BOX lid and all front panel except on
the side of the EL. COMPO. BOX (*1) and turn the power to the
outdoor unit and all connected indoor units. (*2)
After H2P stop blinking (about 12 minutes after turning on the
power), check LED displays as shown in the table [Display of
normal system] and the system is normal state.
If H2P is blinking, check the malfunction code in the remote
controller, and correct the malfunction in accordance with
[Remote controller display malfunction code] in step 6.
(*1)
Lead the refrigerant charge hose etc from the pipe intake. All
front panels must be closed at the procedure (9).
(*2)
If you perform the refrigerant charging operation within the
refrigerant system that have the power off unit, the operation
cannot finish properly.
For confirming the number of the outdoor and indoor units with
the power on, see [How to check how many units are con-
nected] in chapter 11-1. In case of a multi system, turn on the
power to all outdoor units in the refrigerant system.
To energize the crankcase heater, make sure to turn on for 6
hours before starting operation.
(4)
Start the additional refrigerant charge operation.
(About the system settings for additional refrigerant charge oper-
ation, refer to the [Service Precaution] label attached on the EL.
COMPO. BOX lid in the outdoor unit.)
Open valve A immediately after starting the compressor.
(5)
Close the valve A if the “additional charging amount” of refrigerant
was charged, and push the RETURN button (BS3) once.
(6)
Record the charging amount on the accessory “REQUEST FOR
THE INDICATION” label and attach it to the back side of the front
panel.
6.
After completing the additional refrigerant charging perform the
check operation following below.
Note
For check operation, the following work will be performed.
Check of shutoff valve opening
Check of miswiring
Judgment of piping length
Check of refrigerant overcharge
It takes about 40 minutes to complete the check operation.
[Check Operation Procedure]
(1)
Make the onsite setting as needed using the dip switches on the
outdoor unit PC-board (A1P) with the power off (See “12-1 Onsite
Settings With the Power Off”)
(2)
Close the EL. COMPO. BOX lid and all front panels except as the
side of the EL. COMPO. BOX and turn on the power to the out-
door unit and all connected 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.)
(3)
Check the LED display on the outdoor unit PC-board (A1P) is as
shown in the table below and transmission is normal.

(4)
Make the onsite settings as needed using the push button (BS1-
BS5) on the outdoor unit PC-board (A1P) with the power on. (See
“12-2 Onsite Settings With the Power On”)
(5)
Perform the check operation following the Check Operation
Method of the [Service Precautions] label on the EL. COMPO.
BOX lid. The system operation for about 40 minutes and automat-
ically stops the check operation.
If the malfunction code is not displayed in the remote controller
after the system stop, check operation is completed. Normal oper-
ation will be possible after 5 minutes. If the malfunction code is
displayed in the remote controller, correct the malfunction follow-
ing [Remote controller displays malfunction code] and perform the
check operation again.
[Remote controller displays malfunction code]
If any malfunction codes other than the above are displayed, check
the service manual for how to respond.

The shutoff valve of the out-
door unit is left closed.
Open the shutoff valve.

The phases of the power to the
outdoor unit is reversed.
Exchange two of the three phases (L1,
L2, L3) to make a proper connection.
U1
U4
LC
No power is supplied to an out-
door or indoor unit (including
phase interruption).
Make sure the power source wire is prop-
erly connected to the outdoor unit and
revise if necessary.

There is conflict on the con-
nection of transmission wiring
in the system.
Check if the refrigerant piping line and the
transmission wiring are consistent with
each other.

Refrigerant overcharge.
Recalculate the additional amount refrig-
erant from the piping length and correct
the refrigerant charge level by recovering
any excessive refrigerant with a refriger-
ant recovery machine.

Insufficient refrigerant.
Check if the additional refrigerant
charge has been finished correctly.
Recalculate the additional amount
refrigerant from the piping length and
add the adequate amount.
