Step 6: To Manually Charge Refrigerant; Checks After Charging Refrigerant; To Fix The Fluorinated Greenhouse Gases Label; Electrical Installation - Daikin RXYLQ10T7Y1B Series Installation And Operation Manual

INFORMATION
If the total additional refrigerant amount was reached in
step 4 (by pre-charging only), 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
"17 Commissioning" [ 4 33].

INFORMATION
For a multi outdoor unit system, it is not required to
connect all charge ports to a refrigerant tank.
The refrigerant will be charged with ±22 kg in 1 hour time
at an outdoor temperature of 30°C DB or with ±6 kg at an
outdoor temperature of 0°C DB.
If you need to speed up in case of a multiple outdoor
system, connect the refrigerant tanks to each outdoor unit.
NOTICE
▪ The refrigerant charging port is connected to the piping
inside the unit. The unit's internal piping is already
factory charged with refrigerant, so be careful when
connecting the charge hose.
▪ After adding the refrigerant, do not forget to close the
lid of the refrigerant charging port. The tightening
torque for the lid is 11.5 to 13.9 N•m.
▪ In order to ensure uniform refrigerant distribution, it
may take the compressor ±10 minutes to start up after
the unit has started operation. This is not a malfunction.
5 Proceed with the manual charge.
INFORMATION
After charging refrigerant:
▪ Record the additional refrigerant amount on the
refrigerant label provided with the unit and attach it to
the backside of the front panel.
▪ Perform the test
"17 Commissioning" [ 4 33].

Step 6: To manually charge refrigerant

INFORMATION
The manual refrigerant charge operation will automatically
stop within 30 minutes. If charging is not completed after
30 minutes, perform the additional refrigerant charging
operation again.
14.4.7

Checks after charging refrigerant

▪ Are all stop valves open?
▪ Is the amount of refrigerant, that has been added, recorded on the
refrigerant charge label?

NOTICE
Make sure to open all stop valves after (pre-) charging the
refrigerant.
Operating with the stop valves closed will damage the
compressor.

+
1 2
GWP × kg
1000
a If a multilingual fluorinated greenhouse gases label is
delivered with the unit (see accessories), peel off the
applicable language and stick it on top of a.
b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Quantity of fluorinated greenhouse gases of the total
refrigerant charge expressed as tonnes CO
f GWP = Global warming potential
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
Formula to calculate the quantity in CO
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge
label.
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
