3 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 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 "16.1 Preparing the installation site" [
4
46] )
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.
Duct installation (see "16.2.2 Guidelines when installing the ducting" [
4
51] )
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
"20.1 Field setting" [ 4 69]).
Refrigerant piping installation (see
"17 Piping installation" [ 4 57]
)
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.
