1 General safety precautions
Instructions for equipment using R32 refrigerant
If applicable.
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.
NOTICE
▪ Do NOT reuse joints which have been used already.
▪ Joints made in installation between parts of refrigerant
system shall be accessible for maintenance purposes.
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.
Installation space requirements
NOTICE
▪ Pipework shall be protected from physical damage.
▪ Installation of pipework shall be kept to a minimum.
WARNING
If appliances contain R32 refrigerant, then the floor area of
the room in which the appliances are installed, operated
and stored must be larger than the minimum floor area
defined in table below A (m
▪ Indoor units without refrigerant leakage sensor; in
case of indoor units with refrigerant leakage sensor,
consult the installation manual
▪ Outdoor units installed or stored indoors (example:
winter garden, garage, machinery room)
▪ Pipework in unventilated spaces
To determine the minimum floor area
1 Determine the total refrigerant charge in the system (= factory
refrigerant charge +
charged).

2 Determine which graph or table to use.
▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or
floor-standing?
▪ For outdoor units installed or stored indoors, and field piping
in unventilated spaces, this depends on the installation
