2 Specific installer safety instructions

2 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
Installation shall be done by an installer, the choice of
materials and installation shall comply with the applicable
legislation. In Europe, EN378 is the applicable standard.
WARNING
▪ Make sure to install all necessary countermeasures in
case of refrigerant leakage according to standard
EN378 (see "11.1.2 Additional
requirements for CO₂
▪ Make sure to install a CO
and enable the function for refrigerant leak detection
setting" [ 4 21]).
(see "15.1 Field
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 "11.1 Preparing the installation
site" [ 4 12])
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
environment.
CAUTION
Excessive concentrations of refrigerant R744 (CO
closed room can lead to unconsciousness and oxygen
deficiency. Take appropriate measures.
See "To determine the minimum number of appropriate
measures" [ 4 13].
WARNING
In case of mechanical ventilation, take care the ventilated
air is exhausted to the outdoor space and NOT into
another closed area.
WARNING
Install the unit ONLY in locations where the doors of the
occupied space are NOT tight fitting.
WARNING
When using safety shut-off valves, make sure to install
measures such as a bypassing piping with a pressure relief
valve (from liquid pipe to gas pipe). When the safety shut-
off valves close and no measures are installed, increased
pressure may damage the liquid piping.

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
setting" [ 4 21]).
"15.1 Field
Refrigerant piping installation (see
installation" [ 4 17])
CAUTION
Do NOT reuse piping from previous installations.
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 pressure of 120 bar or 90 bar, depending on its
location in the system.
▪ Use K65 unions and fittings approved for a working
pressure of 120 bar or 90 bar, 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.
Electrical installation (see "13 Electrical
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
legislation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST
