LREN8~12A + LRNUN5A
CO₂ ZEAS outdoor unit and capacity up unit

12 Unit installation
WARNING
▪ Install all necessary countermeasures in case of
refrigerant leakage according to standard EN378 (see
"12.1.3Additional installation site requirements for CO₂
refrigerant"[417]).
▪ Install a CO
2
leak detector (field supply) in every room
with refrigerant piping, showcases or blower coils, and -
if present - enable the function for refrigerant leak
detection (see the installation manual of the indoor
units).
WARNING
Fix the unit correctly. For instructions, see "12 Unit
installation"[417].
NOTICE
Adverse effects shall be considered. For example, danger
of water collecting and freezing in discharge pipes for
pressure relief devices, accumulation of dirt and debris, or
blockage of the discharge pipes by solid CO
2
(R744).
INFORMATION
The installer is responsible for supplying the field supply
components.
NOTICE
When indoor installation of the outdoor unit is required, for
example in a technical room, the following requirements
MUST be met:
▪ Air ducts MUST be installed to guide the unit's exhaust
air outside.
▪ Every exhaust air fan in the unit MUST have an
individual airflow path. Make sure no mixture/
recirculation of airflow occurs.
▪ The pressure loss on the air ducts may NOT exceed
the maximum static pressure value ensured by the
High External Static Pressure (ESP) setting (78.40Pa):
- If the ESP, over duct work, is lower than or equal to
30.00Pa, no High ESP setting activation is required.
- If the ESP, over duct work, is higher than 30.00Pa,
the High ESP setting MUST be activated (see the
service manual).
▪ Ensure an adequate ventilation of the technical area
where the units are going to be installed, with façade
air openings to allow fresh air compensation.
▪ For more information about the indoor installation of the
outdoor unit, contact your local dealer.
12.1 Preparing the installation site
12.1.1 Installation site requirements of the
outdoor unit
CAUTION
Appliance NOT accessible to the general public, install it in
a secured area, protected from easy access.
The equipment meets the requirements for commercial
and light-industrial locations when professionally installed
and maintained.
CAUTION
This equipment is NOT intended for use in residential
locations and will NOT guarantee to provide adequate
protection to radio reception in such locations.
NOTICE
If the equipment is installed closer than 30 m to a
residential location, the professional installer MUST
evaluate the EMC situation before installation.
NOTICE
This is a class A product. In a domestic environment this
product may cause radio interference in which case the
user may be required to take adequate measures.
INFORMATION
The sound pressure level is less than 70dBA.
Mind the spacing guidelines. See figure 1 on the inside of the front
cover of this manual.

(a)
Wall height front side: ≤1500mm.
(b)
Wall height air inlet side: ≤500mm.
(c)
Wall height other sides: no limit.
(d)
Calculate p17-h1 and p17-h2 as shown in the figure. Add h1/2 for
maintenance space to the front side. Add h2/2 for maintenance
space to the back side (if wall height exceeds above values).
(e)
B1: pattern for regions without heavy snowfall.
B2: pattern for regions with heavy snowfall.
B3: no limit to wall height.
(f)
C1: pattern for regions without heavy snowfall.
C2: pattern for regions with heavy snowfall.
C3: no limit to wall height.
12.1.2 Additional installation site requirements
of the outdoor unit in cold climates
In heavy snowfall areas it is very important to select an installation
site where the snow will NOT affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is NOT affected by
the snow. If necessary, install a snow cover or shed and a pedestal.
INFORMATION
For instructions on how to install the snow cover, contact
your dealer.
12.1.3 Additional installation site requirements
for CO₂ refrigerant
NOTICE
Although it is recommended to install LREN* and
LRNUN5* outdoors, in some cases it might be needed to
install them inside. In such cases, ALWAYS follow the
indoor installation site requirements for CO
2
refrigerant.
