1-3-2 Installation site
• Provide sufficient space around the unit for servicing and air
circulation as outlined in the unit installation manual.
• Make sure the installation site withstands the weight and
vibration of the unit.
• Make sure the area is well ventilated. Do NOT block any
ventilation openings.
• Make sure the unit is level.
Do NOT install the unit in the following places:
• In potentially explosive atmospheres.
• 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 fiber,
or ignitable dust.
• In places where corrosive gas (example: sulfurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
Instructions for equipment using R32 refrigerant
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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
odor.
WARNING
The appliance should 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 the room size should
be as specified.
(Refer to “Minimum required floor area for each
refrigerant amount charged” on page 1.)
WARNING
Ventilated area
Ensure that the area is in the open or that it is
adequately ventilated before breaking into the system
or conducting any hot work. A degree of ventilation
should continue during the period that the work is
carried out. The ventilation should safely disperse any
released refrigerant and preferably expel it externally
into the atmosphere.
WARNING
Make sure installation, servicing, maintenance and
repair comply with instructions from Daikin and with
applicable legislation (for example national gas
regulations) and are executed only by authorized
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 A
min
(ft
2
) defined in the table
(Refer to “Minimum required floor area for each
refrigerant amount charged” on page 1.)
• no auxiliary devices, which may be a potential ignition
source, are installed in the duct work (example: hot
surfaces with a temperature exceeding 158°F and
electric switching devices)
• only auxiliary devices approved by the manufacturer
are used in the duct work
• an air inlet or outlet is connected directly with a room
by ducting. Do NOT use spaces such as a false ceiling
as a duct for the air inlet or outlet.
CAUTION
Do NOT use potential sources of ignition in searching
for or detection of refrigerant leaks.
NOTICE
• Do NOT re-use joints which have been used already.
• Joints made during installation between parts of the
refrigerant system should be accessible for
maintenance purposes.
NOTICE
• Precautions should be taken to avoid excessive
vibration or pulsation of refrigeration piping.
• Protection devices, piping and fittings should be
protected as much as possible against adverse
environmental effects.
• Provisions should be made for expansion and
contraction of long sections of piping.
• Piping in refrigerating systems should be designed
and installed so that the likelihood of hydraulic shock
damaging the system is minimized.
• The indoor equipment and pipes should be securely
mounted and guarded so that accidental rupture of
equipment or pipes cannot occur from events such as
moving furniture or reconstruction activities.
