Final adjustment of the amount of refrigerant
■
When the unit displays an out of temperature range, the
automatic charging of refrigerant can not be completed.
■
Out of outdoor temperature range
Complete the charging of refrigerant on another time when
the outdoor temperature is warmer than 0°C DB and colder
than 43°C DB.
■
Out of indoor temperature range
Complete the charging of refrigerant on another time when
the indoor temperature is warmer than 20°C DB and colder
than 32°C DB.
In this case, perform a test operation (as explained in the
chapter
"12.4. Test operation" on page 27
) and the unit will work
properly. (The malfunction code
U3
will be displayed on the
indoor unit.)
However, the refrigerant leak detection function can not be used
before completing the refrigerant charging operation and the
judgement of the initial amount of refrigerant by performing the
test operation again.
■
When the temperature has come in range (outdoor = 0~43°C,
indoor
=
20~32°C), perform the overcharging judgement
procedure for completion of the refrigerant charging operation.
Overcharging judgement procedure
1
Close all the front panels except the electric box front panel and
the lid on the side of the electric box.
2
Turn on the power to the outdoor unit and all the connected
indoor units.
3
Press the
button once and set the setting model
H1P = OFF.
4
Press and hold the
button down for 5 seconds.
The system will start operating.
5
Close all the front panels.
After operating for 40
minutes, the operation will stop
automatically.
6
After the system has stopped operating, check the display on
the remote controller.
7
If
E3
,
F6
or
UF
is displayed on the remote controller as a result of
the overcharge judging operation, recover 20% of the charged
amount of refrigerant and perform the overcharge judgement
procedure again.
■
When there is no more overcharging of refrigerant detected,
restart the automatic refrigerant charging from
"1. Start of
automatic charging refrigerant"
as explained on
page 21
again.
11.6. Checks after adding refrigerant
■
Are the stop valves for both liquid and gas open?
■
Is the amount of refrigerant, that has been added, recorded?
