control the indoor units and the indoor unit will
not stop running even if it reaches the set
temperature.
7)
When the system achieves any of below conditions,
the system will exit “r005” mode:
a.
Auto refrigerant charging is finished.
b.
The system displays error or protection code.
c.
Reaches 240 minutes.
d.
Long press “OK” button more than 5 seconds.
If the system exits “r005” mode for condition “b”,
please solve the problem and enter “r005” mode
again. If the system exit “r005” mode for condition
“c”, please enter “r005” mode again to recharge
the refrigerant.
Cautions:
1)
The refrigerant auto gauge point is connected to
the piping inside the outdoor unit. The outdoor
unit's internal piping is already factory charged
with refrigerant, so be careful when connecting the
charge hose.
2)
After adding the refrigerant, do not forget to close
the lid of the refrigerant auto gauge point.
Note:
1)
The digital display will displays “rAF1” if the
outdoor ambient temperature is out of range. The
digital display will displays “rAF2” if the indoor
ambient temperature is out of range. And the
digital display will display “rAF3” if some high
temperature (HT) hydro modules are connected to
the system.
2)
In “r005” mode, please keep the refrigerant tank
connects to the master unit and avoid the
refrigerant tank is empty.
3)
Record the additional refrigerant amount on the
confirmation table of the electronic control box
cover.
4)
For a multi-outdoor unit system, it is
recommended to calculate the required additional
refrigerant manually according to the additional
refrigerant charge rules (refer to the outdoor unit
installation manual).
