6.7.5 Error codes when charging refrigerant
INFORMATION
When a malfunction occurs, X3M outputs a caution (C/C1)
or warning (C/W1) signal, and the H2P LED on the main
PCB lights up.
If a malfunction occurs, close valve B and C immediately. Confirm
the malfunction code and take corresponding action,
"11.3 Solving
problems based on error codes" on page 34 .

f GWP = Global warming potential
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
2
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
6.8 Connecting the electrical wiring
6.8.1 About connecting the electrical wiring
Typical workflow
Connecting the electrical wiring typically consists of the following
stages:
1 Making sure the power supply system complies with the
electrical specifications of the units.
2 Connecting the electrical wiring to the outdoor unit (power
supply, remote operation switch, low-noise switch, output
signals, and options).
3 Connecting the main power supply.
