4.2.15 Liquid / Moisture indicator
Liquid/Moisture Indicator permits checking of the refrigerant flow rate and moisture content in the
refrigerant.
(1) Moisture indicator
(2) Judgement for refrigerant flow rate (normal, shortage or overcharge) (for unit with 5.2 kg
refrigerant)
Color
Green
Judgement
Dry
Yellow
Wet
(Contains excessive moisture)
Replace refrigerant
ATTENTION 1 !!
Judgement
Frozen
operation
Operation
RS<approx. 0˚C
Full
Refrigerant charge is normal if the
indicator is full of liquid when RS is
under approx. 0 deg. C.
RS<approx 0˚C
Flashing
Normal
Refrigerant charge is short if the
indicator shows flashing of refrigerant
when RS is under approx 0 deg.C.
Shortage
RS>approx 0˚C
Flashing
Normal
in most
cases
Refrigerant charge is normal with
flashing in the indicator in most cases,
when RS is above approx 0 deg. C.
Chilled
operation
Flashing
Normal
in most
cases
Refrigerant charge is normal with
flashing in the indicator in most cases,
during chilled operation with capacity
control.
As flashing here
does not mean gas
shortage, do not
charge with
additional refrigerant.
ATTENTION 2 !!
Possibly caused by
overcharging
CAUTION
If the amount of refrigerant is excessive or insufficient, completely recover all refrigerant
and charge with a correct amount of refrigerant.
Additionally charging refrigerant exceeding the specified amount may cause a failure of
the compressor.
(Specified amount of refrigerant: R134a 5.2Kg/LXE10E100 or later)
