2 Specific installer safety
instructions
Always observe the following safety instructions and regulations.
General installation requirements
WARNING
Make sure installation, servicing, maintenance, repair and
applied materials follow the instructions from Daikin
(including all documents listed in “Documentation set”)
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.
NOTICE
Make sure to install all necessary countermeasures in case
of refrigerant leakage according to standard EN378.
Installation site (see "12.1Preparing the installation
site"[411])
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.
CAUTION
Excessive concentrations of refrigerant R744 (CO
2
) in a
closed room can lead to unconsciousness and oxygen
deficiency. Take appropriate measures.
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.
WARNING
Install the unit ONLY in locations where the doors of the
occupied space are NOT tight fitting.
Installing the ducting (see "12.2.2Guidelines when installing
the ducting"[413])
CAUTION
▪ Make sure the installation of the duct does NOT exceed
the setting range of the external static pressure for the
unit. Refer to the technical datasheet of your model for
the setting range.
▪ Make sure to install the canvas duct so vibrations are
NOT transmitted to the duct or ceiling. Use a sound-
absorbing material (insulation material) for the lining of
the duct and apply vibration insulation rubber to the
hanging bolts.
▪ When welding, make sure NOT to spatter onto the
drain pan or the air filter.
▪ If the metal duct passes through a metal lath, wire lath
or metal plate of the wooden structure, separate the
duct and wall electrically.
▪ Install the outlet grille in a position where the airflow will
not come into direct contact with people.
▪ Do NOT use booster fans in the duct. Use the function
to adjust the fan rate setting automatically (see
"16Configuration"[418]).
Refrigerant piping installation (see "13Piping
installation"[415])
CAUTION
Install the refrigerant piping or components in a position
where they are unlikely to be exposed to any substance
which may corrode components containing refrigerant,
unless the components are constructed of materials that
are inherently resistant to corrosion or are suitably
protected against corrosion.
WARNING
▪ Use K65 piping for high-pressure applications with a
working gauge pressure of 120 bar or 90 bar,
depending on its location in the system.
▪ Use K65 unions and fittings approved for a working
gauge pressure of 120bar or 90bar, depending on its
location in the system.
▪ ONLY brazing is allowed for connection of pipes. No
other types of connections are allowed.
▪ Expanding of pipes is NOT allowed.
CAUTION
NEVER bend high pressure piping! Bending can reduce
the pipe thickness and thus weaken the piping. ALWAYS
use K65 fittings.
Electrical installation (see "14Electrical installation"[416])
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the national wiring
regulation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST comply with the applicable
legislation.
