Before Installation - Daikin VAM-GVJU Manual

EDUS711116
CAUTION
• Do not touch the switch with wet fingers. Touching a
switch with wet fingers can cause electric shock.
• Do not allow children to play on or around the unit to
prevent injury.
• Be careful when transporting the product.
• Do not install the unit in the following locations:
(a) Where a mineral oil mist or oil spray or vapor is pro-
duced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in
water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is
produced.
Corroding copper pipes or soldered parts may result
in damage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of
the control system and cause the unit to malfunction.
(d) Where flammable gas may leak, where there is car-
bon fiber or ignitable dust suspension in the air, or
where volatile flammables such as thinner or gaso-
line are handled. Operating the unit in such condi-
tions can cause a fire.
• Do not allow exhaust air to enter the outdoor air intake
vent.
This may cause the air of the room to become contami-
nated, harming the health.
NOTE
• Install the power supply and control wires for the unit at
least 3.3 feet away from televisions or radios to prevent
image interference or noise. Depending on the radio
waves, a distance of 3.3 feet may not be sufficient to
eliminate the noise.
• Dismantling the unit and additional parts must be done
in accordance with the relevant local, state and national
regulations.
• This unit is an appliance that should not be accessible
to the general public.
• Insulate the two outdoor ducts and the supply air duct
to prevent condensation.
If this is not done completely, water may enter the build-
ing, may damage furniture, etc.
• In areas where insects are easily attracted to a light,
such as where there is a window or light near a ventila-
tion opening, extremely small insects can sometimes
infiltrate the room by passing through the ventilation
opening.
Since totally preventing against infiltration by extremely
small insects is difficult, it is important to consider a
serious solution like a filter box (field supply) during the
design process to protect against insect infiltration.

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.
Hold the unit by the hanger brackets (4) when opening the
crate and moving it, and do not lift it holding on to any
other part (especially the duct connecting flange).
2-1 PRECAUTIONS
• Be sure to instruct customers how to properly operate the
unit (especially maintenance of air filter, and operation pro-
cedure) by having them carry out operations themselves
while looking at the manual.
• Where the air contains high levels of salt such as that near
the ocean and where voltage fluctuates greatly such as that
in factories. Also in vehicles or vessels.
