EKVDX32~100A2VEB
VRV system air conditioner
4P664010-1 – 2021.08
This product contains fluorinated greenhouse gases. Do NOT vent gases into the
atmosphere.
The EKVDX contains either R32 or R410A refrigerant.
The EKVDX has an automatic refrigerant detection function. You do not need to
identify the refrigerant via a field setting.
Refrigerant type
R32
R410A
Global warming potential (GWP)
675

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
Please contact your installer for more information.
9.4.1 About R32 refrigerant leakage safety
NOTICE
Functionality of the safety measures are periodically automatically checked. In case
of malfunction, an error code will be displayed on the user interface.
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 EKVDX because this may cause misdetection of the R32
refrigerant leakage sensor.
INFORMATION
The sensor has a lifetime of 10 years. The user interface displays error "
CH-05
"
6 months before the end of the sensor lifetime and error "
CH-02
" after the end of
the sensor lifetime. For more information, refer to the reference guide of the user
interface and contact your dealer.
INFORMATION
To stop alarm of the user interface see the reference guide of the user interface.
INFORMATION
The minimum airflow during normal operation or during the refrigerant leakage
detection is always >240 m
3
/h.
In case detection occurs when the unit is on standby:
-
User interface displays error "
A0-11
", emits alarm sound and status indicator is
blinking.
-
The fan of the heat reclaim ventilation unit begins rotating at ultra high speed.
-
Contact your dealer immediately. For more information, see the installation
manual of the outdoor unit.
