▪
In places where there is machinery that emits electromagnetic waves.
Electromagnetic waves may disturb the control system, and cause malfunction of
the equipment.
▪
In places where there is a risk of fire due to the leakage of flammable gases
(example: thinner or gasoline), carbon fibre, ignitable dust.
▪
In places where corrosive gas (example: sulphurous acid gas) is produced.
Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.
Instructions for equipment using R32 refrigerant
WARNING
▪
Do NOT pierce or burn.
▪
Do NOT use means to accelerate the defrosting process or to clean the
equipment, other than those recommended by the manufacturer.
▪
Be aware that R32 refrigerant does NOT contain an odour.
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 (for example national gas regulation) and
are executed only by authorised persons.
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.
NOTICE
▪
Do NOT re-use joints and copper gaskets which have been used already.
▪
Joints made in installation between parts of refrigerant system shall be accessible
for maintenance purposes.
