Completely recharging refrigerant
Before completely recharging refrigerant, make sure the following is
done:
1 All refrigerant is recovered from the system.
2 The outdoor unit's external refrigerant piping is checked (leak
test, vacuum drying).
3 Vacuum drying on the outdoor unit's internal refrigerant piping is
performed.
NOTICE
Before completely recharging, perform vacuum drying on
the outdoor unit's internal refrigerant piping as well.
NOTICE
To perform vacuum drying or a complete recharge of the
outdoor unit's internal refrigerant piping it is necessary to
activate the vacuum mode (see
deactivate the vacuum mode field setting" on page
which will open required valves in the refrigerant circuit so
the vacuuming process or recharge of refrigerant can be
done properly.
▪ Before vacuum drying or recharging, activate field
setting "vacuum mode".
▪ After finishing vacuum drying or recharging, deactivate
field setting "vacuum mode".
WARNING
Some sections of the refrigerant circuit may be isolated
from other sections caused by components with specific
functions (e.g. valves). The refrigerant circuit therefore
features additional service ports for vacuuming, pressure
relief or pressurizing the circuit.
In case it is required to perform brazing on the unit, ensure
that there is no pressure remaining inside the unit. Internal
pressures need to be released with ALL the service ports
indicated on the figures below opened. The location is
depending on model type.
Location of service ports:
a Internal service port
b Stop valve with service port (liquid)
c Stop valve with service port (gas)

About the refrigerant

WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
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 refrigerant inside the unit is mildly flammable, but
normally does not leak. If the refrigerant leaks in the room
and comes in contact with fire from a burner, a heater, or a
cooker, this may result in fire, or the formation of a harmful
gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer from which you purchased
the unit.
Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.
