11-2 Procedure of Adding Refrigerant charging
and check operation
Warning Electric Shock Warning
• Make sure to close the EL. COMPO. BOX lid before turning on
the power when performing the refrigerant charging operation.
• Perform the setting on the PC-board (A1P) of the outdoor unit and
check the LED display after the power is on via the inspection
door which is in the EL. COMPO. BOX lid.
• Use an insulated rod to operate the push buttons via the EL.
COMPO. BOX’s inspection door.
There is a risk of electric shock if you touch any live parts, since
this operation must be performed with the power on.
Caution
• Make sure to use the protect tool (protective groves and gog-
gles) when charging the refrigerant.
• Due to a danger of liquid hammer, the refrigerant must not be
charged over the allowable maximum amount when charging the
refrigerant.
• Do not perform the refrigerant charging operation under working
for the indoor unit.
• When opening the front panel, make sure to take caution to the fan
rotation during the working.
After the outdoor unit stops operating, the fan may keep rotation
for a while.
Note
• If operation is performed within 12 minutes after the indoor and
outdoor units are turned on, H2P will be lit on and the compressor
will not operate.
• In order to ensure uniform refrigerant distribution, it may take up to
around 10 minutes for the compressor to start up after the unit
starting operating. This is not a malfunction.
Additional charge of refrigerant and the check operation must
be carried out at or below 43°CDB of outside temperature.
<About refrigerant charging>
• The refrigerant charge port is connected to the piping inside the
unit.
When the unit is shipped from the factory, the unit’s internal piping
is already charged with refrigerant, so be careful when connecting
the charge hose.
• After adding the refrigerant, make sure to close the lid of the
refrigerant charging port.
The tightening torque for the lid is 11.5 to 13.9 Nm.
• See [Shutoff valve operation procedure] in chapter 11-1 for details
on how to handle shutoff valves.
• When done or when pausing the refrigerant charging operation,
close the valve of the refrigerant tank immediately. If the tank is
left with the valve open, the amount of refrigerant which is prop-
erly charged may be off the point. More refrigerant may be
charged by any remaining pressure after the machine is stopped.
<About check operation>
• Make sure to perform the check operation after installation. Oth-
erwise, the malfunction code “U3” will be displayed and normal
operation cannot be performed.
And the failure of “Check of miswiring” may also cause abnormal
operation. Performance may drop due to the failure of “Judgment
of piping length”.
• Check operation must be performed for each refrigerant piping
system.
Checking is impossible if plural systems are being done at once.
• The individual problems of indoor units can not be checked.
About these problems check by test run after the check operation
is completed. (See chapter 13)
• The check operation cannot be performed in recovery or other
service modes.
1.
Make sure the following works are complete in accordance with
the installation manual.
Piping work
Wiring work
Air tight test
Vacuum drying
Installation work for indoor unit
2.
Calculate the “additional charging amount” using “How to calcu-
late the additional refrigerant to be charged” in “6-5 Example of
connection”.
3.
Open the valve C (See the figure 31. The valve A,B and the liquid
pipe, suction gas pipe shutoff valves must be left closed), and charge
the refrigerant of the “additional charging amount” from the liquid
side shutout valve service port.

4.
If the “additional charging amount” was charged fully, close the
valve C and go to step 6.
If the “additional charging amount” was not charged fully, close
the valve C and go to step 5.
5.
Perform the refrigerant charging following [Automatic refrigerant
charging operation procedure] as shown below. And charge the
remaining refrigerant of the “additional charging amount”.
Note
• For performing the automatic refrigerant charging operation, the
push button on the PC-bord (A1) of outdoor unit are used. (See
figure 33.)
And the refrigerant are charged from the refrigerant charge port
via the valve A. (See figure 32.) For operating the push button and
opening or closeing the valves, follow the procedure.
• During Automatic refrigerant charging operation, the system will
select charging mode (cooling mode or heating mode) by the tem-
perature condition as follows.
When charging in cooling mode, the system will stop operation
when the required amount of refrigerant is charged.
During charging in heating mode, a person must manually close
valve A and stop operation.
Beforehand, check the remaining refrigerant that is needed to
charge based on the “additional charging amount” in step 2 and
the charged amount in step 3.
• The refrigerant will be charged about 30kg in one hour at outdoor
temp. 30°C DB (about 12kg at outdoor temp. 0°C DB).
• During Automatic refrigerant charging operation, you can stop the
operation forcedly by pushing MODE button (BS1).

(2) • Close the EL. COMPO. BOX (1) lid and all front panel except on
the EL. COMPO. BOX (1) side. (*1) And turn the power to the
outdoor unit and all connected indoor units. (*2)
