2 Specific installer safety
instructions
Always observe the following safety instructions and regulations.
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 "12 Unit installation" [
4
13])
WARNING
The appliance using R32 refrigerant shall be stored so as
to prevent mechanical damage and in a well-ventilated
room without continuously operating ignition sources (e.g.
open flames, an operating gas appliance, or an operating
electric heater). The room size shall be as specified in the
General safety precaution.
CAUTION
Appliance NOT accessible to the general public. Install it in
a secured area, protected from easy access.
This unit is suitable for installation in a commercial, light
industrial, household and residential environment.
WARNING
For units using the R32 refrigerant it is necessary to keep
any required ventilation openings clear of obstructions.
CAUTION
Do NOT remove the (milky white) tape from the exterior of
the indoor unit. Removing the tape may cause an electric
shock or a fire.
Refrigerant piping installation (see "13 Piping
installation" [
4
17])
CAUTION
Piping MUST be installed according to instructions given in
"13 Piping installation" [
4
17]. 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 "14 Electrical installation" [
4
19])
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
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 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, 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
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.
