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.
WARNING
▪ Take precautions to avoid excessive vibration or
pulsation to refrigeration piping.
▪ Protect the protection devices, piping and fittings as
much as possible against adverse environmental
effects.
▪ Provide space for expansion and contraction of long
runs of piping.
▪ Design and install piping in refrigerating systems such
as to minimise the likelihood of hydraulic shock
damaging the system.
▪ Mount the indoor equipment and pipes securely and
protect them to avoid accidental rupture of equipment
or pipes in case of 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.
