Charging in cooling mode
6. Start up
Wait while the unit is preparing for charging in cooling mode.
7. Ready
Press the button once within 5 minutes.
If the button is not pushed within 5 minutes,
P2
will be
displayed on the remote controller. Refer to "4 Remote controller
malfunction code display" on page 24 .
8. Operation
When the following LED display is shown, open valve A and
close the frontpanel. If the frontpanel is left open, the system
can not operate properly during the refrigerant charging.
*
= The state of this LED is not important.
9. Complete
If the display on the remote controller shows a flashing
PE
code,
charging is almost finished.
When the unit stops operating, close valve A immediately and
check the LEDs and check if the
P9
code is displayed on the
remote controller. When the charging amount is little, the
PE
code may not be displayed, but instead the
P9
code will be
displayed immediately.
If it is not as shown above, correct the malfunction (as indicated
in the display of the remote controller) and restart the complete
charging procedure.

2. Open valve C (valves A and B and the stop valves must be left
closed) and charge the required amount of refrigerant through
the liquid side stop valve service port.
■
When the required amount of refrigerant is fully charged,
close valve C. Record the amount of refrigerant that was
added on the additional refrigerant charge label provided
with the unit and attach it on the back side of the front panel.
Perform the test procedure as described in
"In case
refrigerant was added without using the leak detection
function (pre-charging, charging in heating mode)" on
page 28
.
■
When the additional charging is not complete, perform the
procedure explained in the chapter
"Charge with operating
outdoor unit" on page 22 .
