Before Installation - Daikin FCQ18AAVJU Installation Manual

1. BEFORE INSTALLATION

When unpacking the indoor unit or moving the unit after
unpacked, hold the hanger brackets (4 places) and do not
apply force to other parts (particularly refrigerant piping,
drain piping and resin parts).
• Make sure to check in advance that the refrigerant to be
used for installation work is R410A.
The air conditioner will not operate properly without the
correct refrigerant.
• 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.
(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 until the installation
begins.
• 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 filter, operation pro cedures,
and temperature adjustment).
• For selection of installation location, use the installation
pattern combined packing material paper as reference.
• Do not use the air conditioner where in the salty atmo-
sphere such as coastal areas, vehicles, vessels or the
voltage fluctuation 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.

• Joint insulating material (8) and (9) are for field piping that
is insulated to a thickness of 3/8 in. (10 mm) or less. If the
field piping is insulated to a thickness of more than 3/8 in.
(10 mm), instead of using joint insulating material (8) and

that are suitable for the field piping, and be sure to carry out
insulation according to the procedure in this manual.
If not insulated, water leakage may be caused by conden-
sation.
