3P599603-1E – 2024.02
General
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.
Unit installation (see "12Unit installation"[415])
For additional installation site requirements, read also
"2.1Instructions for equipment using R32 refrigerant"[45].
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
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
Keep any required ventilation openings clear of
obstructions.
Refrigerant piping installation (see "13Piping
installation"[418])
CAUTION
Piping MUST be installed according to instructions given in
"13Piping installation" [4 18]. Only mechanical joints (e.g.
braze+flare connections) that are compliant with the latest
version of ISO14903 can be used.
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.
Electrical installation (see "14Electrical installation"[419])
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
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provides full
disconnection under overvoltage category III.
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.
CAUTION
▪ Each indoor unit has to be connected to a separate
user interface. Only a safety system compatible remote
controller can be used as the user interface. See
technical data sheet for remote controller compatibility
(e.g. BRC1H52/82*).
▪ The user interface has to be put in the same room as
the indoor unit. For details, please refer to the
installation and operation manual of the user interface.
CAUTION
In case shielded wire is used, connect the shielding to the
outdoor unit side only.
Commisioning (see "15Commissioning"[420])
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.
Configuration (see "16Configuration"[421])
WARNING
In case of R32 refrigerant, terminal connections T1/T2 are
for fire alarm input ONLY. Fire alarm has a higher priority
than R32 safety and shuts the entire system down.
