Specific installer safety
instructions
Always observe the following safety instructions and regulations.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it will
cause injury.
General installation requirements
WARNING
▪ Make sure to install all necessary countermeasures in
case of refrigerant leakage according to standard
EN378 (see
"12.1.3 Additional installation site
▪ Make sure to install a CO
2
leak detector (field supply)
and enable the function for refrigerant leak detection
(see the installation manual of the indoor unit (air
conditioning)).
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
"12.1 Preparing the installation
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.
NOTICE
Serious injury and/or damage can result from blow off of
the liquid receiver safety valve (see
▪ NEVER service the unit when the pressure at the liquid
receiver is higher than the set pressure of the liquid
receiver safety valve (86 bar g±3%). If this safety valve
releases refrigerant, it can cause serious injury and/or
damage.
▪ If the pressure >86 bar, ALWAYS discharge from
pressure relief devices before servicing.
▪ It is recommended to install and secure blow off piping
to the safety valve.
▪ Remove the refrigerant before altering the safety valve
position.
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).
