Duct connection kit (EKBSDCK)
This kit is required when you install ducting on the air inlet side. See
the examples in "13.2Possible configurations"[424] and "13.5.1To
install the ducting"[427].
This kit can also be used when measuring the airflow. See
"17.2.3About measuring the airflow rate"[441].
Joint kit (EKBSJK)
This kit is required when you make a connection with e.g.
FXMA200A and FXMA250A. When using the joint kit, change the
DIP switch settings. See "15.4To set the DIP switches"[435].
Drain up kit (K-KDU303KVE)
▪ Only this optional drain up kit can be used on the BS unit. Do NOT
use another drain pump kit.
▪ Do NOT route the interconnection wiring of the BS unit together
with the power supply wire of the drain up kit.
▪ Route the power supply wire and relay harness of the drain up kit
inside the BS unit as shown in the figure below.
▪ Position the ferrite core on the relay harness of the drain up kit
inside the switch box of the BS unit.

12 Special requirements for R32
units
12.1 Installation space requirements
NOTICE
▪ The pipework shall be securely mounted and guarded
protected from physical damage.
▪ Keep the pipework installation to a minimum.
12.2 System layout requirements
The VRV 5 heat recovery uses R32 refrigerant, which is rated as
A2L and is mildly flammable.
To comply with the requirements of enhanced tightness refrigerating
systems of the IEC60335-2-40, this system is equipped with shut-off
valves in the BS unit and an alarm in the remote controller.
The safety measures that are needed for the BS unit are explained
in more detail below. If they are followed, no additional safety
measures for the BS unit are required. Carefully follow the
installation requirements for the BS unit as explained in this manual.
Follow the installation requirements described in the outdoor unit
and indoor unit installation and operation manuals to ensure that the
complete system is compliant with legislation.
Outdoor unit installation
For installation of the outdoor unit, see the installation and operation
manual delivered with the outdoor unit.
Indoor unit installation
Room area limitations apply for the indoor units. Details are
explained in the installation and operation manual delivered with the
outdoor unit. For installation of the indoor unit, see the installation
and operation manual delivered with the indoor unit. For
compatibility of indoor units, see the latest version of the technical
data book of the outdoor unit.
Remote controller requirements
To install the remote controller, see the installation and operation
manual delivered with the remote controller. For requirements on
where and how to use a remote controller and which type to use,
see the installation and operation manual delivered with the outdoor
unit.
BS unit installation
Depending on the room size in which the BS unit is installed and the
total amount of refrigerant in the system, other safety measures are
necessary. See "12.3 To determine the required safety
measures" [4 13]. For the total amount of refrigerant in the system,
see the installation and operation manual delivered with the outdoor
unit.
A terminal for external output is available in the BS unit. This SVS
output can be used when additional countermeasures are needed,
or when the BS unit is installed in a room size where an external
alarm is a sufficient safety measure. The SVS output is a potential-
free contact on terminal X6M that closes in case a refrigerant leak is
detected or if the R32 sensor of the BS unit fails or is disconnected.
For more information about the SVS output, see "15.5 To connect
the external outputs"[435].
Piping requirements
CAUTION
Piping MUST be installed according to instructions given in
"14 Piping installation" [4 30]. Only mechanical joints (e.g.
braze+flare connections) that are compliant with the latest
version of ISO14903 can be used.
Low temperature solder alloys shall not be used for pipe
connections.
For piping installed in the occupied space, make sure that the piping
is protected against accidental damage. Piping should be checked
according to the procedure as mentioned in the installation and
operation manual delivered with the outdoor unit.
12.3 To determine the required safety
measures
Step 1 – Determine the total amount of refrigerant in the system.
See the installation and operation manual delivered with the outdoor
unit.
Step 2 – Determine the area of the room in which the BS unit is
installed.
The room area can be determined by projecting the walls, doors and
partitions to the floor and calculating the enclosed area. Spaces
connected by only false ceilings, ductwork, or similar connections
are not considered a single space.
Step 3 – Use the graphs or tables (see "Figure 1" [4 2] at the
beginning of this manual) to determine the required safety measures
for the BS unit.
