EKVDX32~100A2VEB
VRV system air conditioner
4P555815-1A – 2021.08
WARNING
R410A is a non-combustible
refrigerant, and R32 is a mildly
flammable refrigerant; they normally do
NOT leak. If the refrigerant leaks in the
room and comes into contact with fire
from a burner, a heater, or a cooker,
this may result in a fire (in case of
R32), or the formation of a harmful gas.
Turn off any combustible heating
devices, ventilate the room, and
contact the dealer from where you
purchased the unit.
Do NOT use the unit until a service
person confirms that the part from
which the refrigerant leaked has been
repaired.
WARNING
It is necessary to replace the R32
refrigerant leakage sensor after every
detection or at the end of the lifetime.
ONLY authorised persons may replace
the sensor.
WARNING
The heat reclaim ventilation unit filters
MUST be cleaned after a drop in
airflow rate has been detected. ONLY
authorised personnel can execute this.
Troubleshooting (see
14])
WARNING
Stop operation and shut OFF the
power if anything unusual occurs
(burning smells etc.).
Leaving the unit running under such
circumstances may cause breakage,
electrical shock or fire. Contact your
dealer.
DANGER: RISK OF
ELECTROCUTION
To clean the air conditioner, be sure to
stop operation and turn all power
supplies OFF. Otherwise, an electrical
shock and injury may result.

About the system
WARNING
▪ Do NOT modify, disassemble, remove, reinstall or
repair the unit yourself as incorrect dismantling or
installation may cause an electrical shock or fire.
Contact your dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe and non-toxic. R410A is a non-combustible
refrigerant, and R32 is a mildly flammable refrigerant,
but they will generate a toxic gas when they
accidentally leak into a room where combustible air
from fan heaters, gas cookers, etc. is present. Always
have qualified service personnel confirm that the point
of leakage has been repaired or corrected before
resuming operation.
NOTICE
Do NOT use the system for other purposes. In order to
avoid any quality deterioration, do NOT use the unit for
cooling precision instruments, food, plants, animals, or
works of art.
NOTICE
For future modifications or expansions of your system:
A full overview of allowable combinations (for future
system extensions) is available in technical engineering
data and should be consulted. Contact your installer to
receive more information and professional advice.
CAUTION
This unit is equipped with electrically powered safety
measures, such as a refrigerant leak detector. In order to
be effective, the unit must be electrically powered at all
times after installation, except for short service periods.
4.1
System layout
The EKVDX is an airconditioning unit for pretreatment of incoming
supply air from a VAM heat reclaim ventilation unit. For comfort
temperature control, it is still required to install a normal indoor unit.
Do not place the EKVDX before the heat reclaim ventilation unit.
