6 Maintenance and service
6.1 Precautions for maintenance and
service
CAUTION
See "3 User safety instructions" [4 6] to acknowledge all
related safety instructions.
NOTICE
NEVER inspect or service the unit by yourself. Ask a
qualified service person to perform this work.
NOTICE
Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
Following symbols may occur on the indoor unit:
Symbol Explanation
Measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
6.2 Periodic check of the ventilated
enclosure
In case a ventilated enclosure is used as a safety measure for the
BS unit, the installer or service agent can check the airflow rate
periodically to confirm that it still meets the requirements.
Note: The periodic airflow rate check can be disabled by changing
the setting [2-58] "Maintenance cycle for BS unit AFR check" on the
outdoor unit.
6.3 About the refrigerant
CAUTION
See "3 User safety instructions" [4 6] to acknowledge all
related safety instructions.
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
Periodical inspections for refrigerant leaks may be required
depending on the applicable legislation. Contact your installer for
more information.
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg]/1000
Contact your installer for more information.
WARNING
Safety shut-off valves shall not be reset until the room has
been ventilated. Resetting may result in additional
flammable refrigerant to be released into the room.
6.3.1 About the refrigerant leakage sensor
WARNING
The R32 refrigerant leakage sensor must be replaced after
every detection or at the end of its lifetime. ONLY
authorised persons may replace the sensor.
NOTICE
The R32 refrigerant leakage sensor is a semiconductor
detector which may incorrectly detect substances other
than R32 refrigerant. Avoid using chemical substances
(e.g. organic solvents, hair spray, paint) in high
concentrations, in the close proximity of the BS unit
because this may cause misdetection by the R32
refrigerant leakage sensor.
NOTICE
Functionality of the safety measures are periodically
automatically checked. In case of malfunction, an error
code will be displayed on the user interface.
INFORMATION
The sensor has a lifetime of 10 years. The user interface
displays error "CH-22" 6 months before the end of the
sensor lifetime and error "CH-23" after the end of the
sensor lifetime. For more information, see the reference
guide of the user interface and contact your dealer.
In case of detection
1 The user interface of the indoor units connected to the BS unit
displays error "A0-20".
2 If applicable, the safety measures of the BS unit are activated.
These can be the following:
▪ the external alarm emits a signal, or
▪ the extraction fan and damper of the BS unit start operating in
case of a ventilated enclosure.
3 Contact your dealer immediately. For more information, see the
installation manual of the outdoor unit.
INFORMATION
To stop the alarm of the user interface, see the reference
guide of the user interface.
7 Troubleshooting
If one of the following malfunctions occurs, take the measures
shown below and contact your dealer.
WARNING
In case of a refrigerant leak, the system needs power to
contain the problem.
1. Do NOT turn OFF the power supply.
2. Contact your dealer.
Possible consequence: Leaking refrigerant can lead to
suffocation, asphyxiation and fire.
In case anything else unusual occurs (burning smells etc.):
1. Stop operation.
2. Shut OFF the power
3. Contact your dealer.
Possible consequence: Leaving the unit running under
such circumstances may cause breakage, electrical shock
or fire.
The system MUST be repaired by a qualified service person.
