Before Installation - Daikin FXMQ15TBVJU Installation Manual

2. BEFORE INSTALLATION

When unpacking the indoor unit or moving the unit after
unpacked, hold the hanger brackets (4 locations) and do
not apply force to other parts (particularly refrigerant pip-
ing, drain piping).
• Make sure to check in advance that the refrigerant to be
used for installation work is R410A.
(The air conditioner will not properly operate if a wrong
refrigerant is used.)
• For installation of the outdoor unit and additional refriger-
ant charge, refer to the installation manual attached to the
outdoor unit.
• Do not throw away the accessories until the installation
work is completed.
• Do not damage the equipment or property when carrying
the indoor unit into the room.
(1) Measure the unit with packaging to ensure the unit
can be carried safely while still packaged.
(2) Determine the route to carry the unit into the room.
(3) Do not unpack the unit until it is carried to the installa-
tion location.
Where unpacking is unavoidable, use a sling of soft
material or protective plates together with a rope when
lifting, to avoid damage or scratches to the indoor unit.
• After the indoor unit is carried into the room, to avoid the
indoor unit from getting damaged, take measures to protect
the indoor unit with packing materials.
• Have the customer actually operate the air conditioner
while looking at the operation manual.
Instruct the customer how to operate the air conditioner
(particularly cleaning of the air filters, operation pro cedures,
and temperature adjustment).
• Do not use the air conditioner in a salty atmosphere such
as coastal areas, vehicles, vessels or where voltage fluc-
tuation is frequent such as factories.
• Take off static electricity from the body when carrying out
wiring and the control box cover is removed.
The electric parts may be damaged.
