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 (for example national gas regulation) and
are executed ONLY by authorised persons.
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
▪
Incomplete flaring may cause refrigerant gas leakage.
▪
Do NOT re-use flares. Use new flares to prevent refrigerant gas leakage.
▪
Use flare nuts that are included with the unit. Using different flare nuts may
cause refrigerant gas leakage.
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 the installation between parts of the refrigerant system shall be
accessible for maintenance purposes.
