General
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
site" [
4
11])
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.
CAUTION
The total refrigerant charge in the system cannot exceed
the requirements for minimum floor area of the smallest
room that is served. For minimum floor area requirements
for indoor units, see the installation and operation manual
of the outdoor unit.
Duct installation (see "12.2.2 Guidelines when installing the
ducting" [
4
13])
WARNING
Do NOT install operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater) in the duct work.
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
"16.1 Field setting" [
4
18]).
Refrigerant piping installation (see "13 Piping
installation" [
4
16])
CAUTION
▪ Do NOT use mineral oil on flared part.
▪ Do NOT reuse piping from previous installations.
▪ NEVER install a drier to this R32 unit to guarantee its
lifetime. The drying material may dissolve and damage
the system.
CAUTION
▪ Incomplete flaring may cause refrigerant gas leakage.
▪ Do NOT re-use flares. Use new flares to prevent
refrigerant gas leakage.
▪ Use flare nuts that are included with the unit. Using
different flare nuts may cause refrigerant gas leakage.
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: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
Electrical installation (see "14 Electrical installation" [
4
16])
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 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 shock.
▪ 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, stranded conductor wires,
extension cords, or connections from a star system.
They can cause overheating, electrical shock 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
ALWAYS use multicore cable for power supply cables.
WARNING
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provide full
disconnection under overvoltage category III.
