Piping requirements
CAUTION
Piping MUST be installed according to instructions given in
"15 Piping installation" [4 26]. 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 "15.3 Checking the
refrigerant piping"[429].

For installation of the remote controller, please refer to the
installation and operation manual delivered with the remote
controller. Any compatible air curtain equipped with a R32 sensor
must be connected with a R32 safety system compatible remote
controller (e.g. BRC1H52/82* or later type). In case of air curtains,
the remote controllers have implemented safety measures that will
warn the user visually and audibly in case of a leak.
For installation of the remote controller of an air curtain, it is
mandatory to follow the requirements:
1 Only a safety system compatible remote controller can be used.
See technical data sheet for remote controller compatibility (e.g.
BRC1H52/82*).
2 The air curtain must be connected to a compatible remote
controller.
13.1.3 To determine the required safety
measures
Step 1 – Determine the total amount of refrigerant in the system.
Use the values on the unit nameplate to determine the total amount
of refrigerant in the system.

(a)
The factory charge value can be found on the nameplate.
(b)
The R value (additional refrigerant to be charged) is calculated in
"16.2To determine the additional refrigerant amount"[431].
NOTICE
The total refrigerant charge amount in the system MUST
always be lower than 79.8kg.
Step2 – Determine the area of the room (A) where an air curtain is
installed/serving.
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 4" [4 3] at the
beginning of this manual) to determine the required safety measures
for the air curtain.

(c) No safety measure (=No safety measure)
(d) Alarm OR Natural ventilation (=Alarm OR Natural
ventilation)
(e) NOT allowed (=NOT allowed)
(f) Alarm + Natural ventilation (=Alarm + Natural ventilation)
Use the total amount of refrigerant in the system and the area of the
room in which the air curtain is installed/serving, to check which
safety measure is required.
Note: When "No safety measure" is required, it is still allowed to
apply natural ventilation or alarm) if wanted. Follow the respective
instructions as described further below.
Note: When natural ventilation is required, it is still allowed to apply
alarm) if wanted. Follow the respective instructions as described
further below.
Use the first graph (Lowest underground floor
(a)
) in case the air
curtain is installed/serving in the lowest underground floor of a
building. For other floors, use the second graph (All other floors
(b)
).
OTHER FLOORS
LOWEST UNDERGROUND FLOOR
The graphs and table are based on an installation height of the air
curtain between 1.8 m and 2.2 m (bottom of the air curtain). See
"14.1.1Installation site requirements of the outdoor unit"[424].
If the installation height is more than 2.2m, different boundaries for
the applicable safety measures can apply. To know which safety
measure is required in case the installation height is more than
2.2m, refer to the online tool (VRV Xpress).
NOTICE
A compatible air curtain cannot be installed lower than
1.8m from the lowest point of the floor.
Example
The total amount of refrigerant in the ERA system is 10kg. The air
curtain is installed in spaces that do NOT belong to the lowest
underground floor of the building. The space in which the air curtain
is installed has a room area of 50m².
