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"[412])
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.
Refrigerant piping installation (see "13Piping
installation"[416])
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"[417])
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.
WARNING
▪ If the power supply has a missing or wrong N-phase,
equipment might break down.
▪ Establish proper earthing. Do NOT earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earthing may cause electrical shocks.
▪ Install the required fuses or circuit breakers.
▪ Secure the electrical wiring with cable ties so that the
cables do NOT come in contact with sharp edges or
piping, particularly on the high-pressure side.
▪ Do NOT use taped wires, extension cords, or
connections from a star system. They can cause
overheating, electrical shocks or fire.
▪ Do NOT install a phase advancing capacitor, because
this unit is equipped with an inverter. A phase
advancing capacitor will reduce performance and may
cause accidents.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, MUST be installed in the fixed wiring.
WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
Commissioning (see "15Commissioning"[418])
WARNING
If the panels on the indoor units are not installed yet, make
sure to power OFF the system after finishing the test run.
To do so, turn OFF operation via the user interface. Do
NOT stop operation by turning OFF the circuit breakers.
