General installation requirements
WARNING
▪
Make sure to install all necessary countermeasures in case of refrigerant leakage
according to standard EN378 (see
"15.1.3 Additional installation site
requirements for CO₂ refrigerant"
53]).
▪
Make sure to install a CO
2
leak detector (field supply) in every room with
refrigerant piping, air conditioning units, showcases or blower coils, and enable
the function for refrigerant leak detection (see the installation manual of the
indoor units).
WARNING
Make sure installation, servicing, maintenance, repair and applied materials follow
the instructions from Daikin and, in addition, comply with applicable legislation and
are performed by qualified persons only. In Europe and areas where IEC standards
apply, EN/IEC 60335-2-40 is the applicable standard.
Installation site (see
"15.1 Preparing the installation site"
)
CAUTION
Appliance not accessible to the general public, install it in a secured area, protected
from easy access.
This unit, both indoor and outdoor, is suitable for installation in a commercial and
light industrial environment.
WARNING
All installed safety valves MUST ventilate to the outdoor space and NOT into a closed
area.
CAUTION
If the safety valve operates, CO
2
gas may concentrate inside the casing of the
outdoor unit. Therefore, you should ALWAYS take a distance for your own safety. You
can close the outdoor unit if your portable CO
2
detector confirmed that the
concentration of CO
2
is at an acceptable level. For example, if 7 kg CO
2
is released
inside the casing, it takes around 5 minutes until the concentration of CO
2
is low
enough.
WARNING
Do NOT place objects below the indoor and/or outdoor unit that may get wet.
Otherwise condensation on the main unit or refrigerant pipes, air filter dirt or drain
blockage may cause dripping, and objects under the unit may get dirty or damaged.
WARNING
Install the unit only in locations where the doors of the occupied space are not tight
fitting.
