Inside the outdoor unit
To insulate the refrigerant piping, proceed as follows:

d
a Sealant
b Insulation
c Vinyl tape around curves
d Vinyl tape against sharp edges
1 Insulate the gas, liquid, and equalising piping.
2 Wind heat insulation around the curves, and then cover it with
vinyl tape (c, see above).
3 Make sure the field piping does not touch any compressor
components.
4 Seal the insulation ends (sealant etc.) (b, see above).
5 Wrap the field piping with vinyl tape (d, see above) to protect it
against sharp edges.
6 If the outdoor unit is installed above the indoor unit, cover the
stop valves with sealing material to prevent condensed water
on the stop valves from moving to the indoor unit.
NOTICE
Any exposed piping can cause condensation.
7 Reattach the service cover and the piping intake plate.
8 Seal all gaps to prevent snow and small animals from entering
the system.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
15.3.7 To check for leaks after charging
refrigerant
After charging refrigerant in the system an additional leak test must
be performed. Refer to "16.9 To check refrigerant piping joints for
leaks after charging refrigerant"[439].
16 Charging refrigerant
16.1 Precautions when charging
refrigerant
WARNING
▪ Only use R32 as refrigerant. Other substances may
cause explosions and accidents.
▪ R32 contains fluorinated greenhouse gases. Its global
warming potential (GWP) value is 675. Do NOT vent
these gases into the atmosphere.
▪ When charging refrigerant, ALWAYS use protective
gloves and safety glasses.
NOTICE
If the power of some units is turned off, the charging
procedure cannot be finished properly.
NOTICE
In case of a multiple outdoor system, turn on the power of
all outdoor units.
NOTICE
Turn ON the power 6 hours before operation in order to
have power running to the crankcase heater and to protect
the compressor.
NOTICE
If operation is performed within 12 minutes after the indoor
and outdoor unit(s) are powered on, the compressor will
not operate before the communication is established in a
correct way between outdoor unit(s) and indoor unit(s).
NOTICE
Make sure all connected indoor units are recognised (see
[1‑10] in "18.1.7Mode 1: monitoring settings"[445]).
NOTICE
Before starting charging procedures, check if the
7‑segment display indication of the outdoor unit A1P PCB
is as normal (see "18.1.4To access mode 1 or 2"[444]).
If a malfunction code is present, see "22.1 Solving
problems based on error codes"[452].
NOTICE
Close the front panel before any refrigerant charge
operation is executed. Without the front panel attached the
unit cannot judge correctly whether it is operating properly
or not.
NOTICE
In case of maintenance and the system (outdoor unit +
SVunit + fieldpiping + indoorunits) does not contain any
refrigerant any more (e.g., after refrigerant reclaim
operation), the unit has to be charged with its original
amount of refrigerant (refer to the nameplate on the unit)
and the determined additional refrigerant amount.
