3.1 Instructions for equipment using R32 refrigerant
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
▪
Do NOT pierce or burn refrigerant cycle parts.
▪
Do NOT use cleaning materials or means to accelerate the defrosting process
other than those recommended by the manufacturer.
▪
Be aware that the refrigerant inside the system is odourless.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-
ventilated room without continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric heater) and have a room
size as specified below.
WARNING
Make sure installation, servicing, maintenance and repair comply with instructions
from Daikin and with applicable legislation and are executed ONLY by authorised
persons.
WARNING
If one or more rooms are connected to the unit using a duct system, make sure:
▪
there are no operating ignition sources (example: open flames, an operating gas
appliance or an operating electric heater) in case the floor area is less than the
minimum floor area A (m²).
▪
no auxiliary devices, which may be a potential ignition source, are installed in the
duct work (example: hot surfaces with a temperature exceeding 700°C and
electric switching device);
▪
only auxiliary devices approved by the manufacturer are used in the duct work;
▪
air inlet AND outlet are connected directly to the same room by ducting. Do NOT
use spaces such as a false ceiling as a duct for the air inlet or outlet.
NOTICE
▪
Precautions shall be taken to avoid excessive vibration or pulsation to
refrigeration piping.
▪
Protection devices, piping and fittings shall be protected as far as possible against
adverse environmental effects.
▪
Provision shall be made for expansion and contraction of long runs of piping.
▪
Piping in refrigerating systems shall be designed and installed such as to minimise
the likelihood of hydraulic shock damaging the system.
▪
The indoor equipment and pipes shall be securely mounted and guarded such
that accidental rupture of equipment or pipes cannot occur from events such as
moving furniture or reconstruction activities.
CAUTION
Do NOT use potential sources of ignition in searching for or detection of refrigerant
leaks.
