Before Installation - Daikin VRV SYSTEM FXNQ20A2VEB Installation Manual

• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray
or vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water
leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is
produced.
Corroding of copper pipes or soldered parts may result
in refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where flammable gas may leak, where there is carbon
fibre or ignitable dust suspensions in the air, or where vol-
atile flammables such as paint thinner or gasoline are han-
dled.
Operating the unit in such conditions may result in fire.
• Do not touch the heat exchanger fins.
Improper handling may result in injury.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any
PP bands for a means of transportation. It is dangerous.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden
parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that
children will not play with them. If children play with a plastic
bag which was not torn apart, they face the risk of suffocation.
• Do not turn off the power immediately after stopping operation.
Always wait at least 5 minutes before turning off the power.
Otherwise, water leakage and trouble may occur.
• In a domestic environment this product may cause radio
interference in which case the user may be required to take
adequate measures.
Follow national standards for installation work.

BEFORE INSTALLATION

The accessories needed for installation must be retained in
your custody until the installation work is completed. Do
not discard them!
1. Decide upon a line of transport.
2. Leave the unit inside its packaging while moving, until
reaching the installation site. Where unpacking is unavoid-
able, use a sling of soft material or protective plates
together with a rope when lifting, to avoid damage or
scratches to the unit.
When moving the unit at or after opening, hold the unit by
the hanger brackets. Do not apply force to the refrigerant
piping, drain piping or flange parts.
Be sure to check the type of R410A refrigerant to be used
before installing the unit.
(Using an incorrect refrigerant will prevent normal opera-
tion of the unit.)
For the installation of an outdoor unit, refer to the installation
manual attached to the outdoor unit.
2-1 PRECAUTIONS
• Be sure to instruct customers how to properly operate the
unit (operating different functions, and adjusting the temper-
ature ) by having them carry out operations themselves while
looking at the operation manual.
• Do not install in locations where the air contains high levels of
salt such as that near the ocean and where voltage fluctuates
greatly such as that in factories, or in vehicles or vessels.
