VRV IV System Air Conditioner

4P345099-1 – 2013.04

WARNING

Do not install the air conditioner at any place where
flammable gas may leak out. If the gas leaks out and
stays around the air conditioner, a fire may break out.

In order to avoid electric shock or fire, make sure that
an earth leak detector is installed.

Be sure the air conditioner is electrically earthed. In
order to avoid electric shock, make sure that the unit
is grounded and that the earth wire is not connected
to gas or water pipe, lightning conductor or telephone
earth wire.

Do not place a flower vase or anything containing
water on the unit. Water may enter the unit, causing
an electric shock or fire.

Avoid placing the controller in a spot which can be
splashed with water. Water entering the machine may
cause an electric leak or may damage the internal
electronic parts.

CAUTION

It is not good for your health to expose your body to
the air flow for a long time. 

In order to avoid injury, do not remove the fan guard of
the outdoor unit.

To avoid oxygen deficiency, ventilate the room
sufficiently if equipment with burner is used together
with the air conditioner.

Do not allow anyone to climb on the outdoor unit or
avoid placing any object on it. Falling or tumbling may
result in injury.

Never expose little children, plants or animals directly
to the air flow.

Do not let children play on and around the outdoor
unit. If they touch the unit carelessly, it may result in
injury.

Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are
dangerous to touch and appliance problems may
happen. For checking and adjusting the internal parts,
contact your dealer.

Do not touch the heat exchanger fins. These fins are
sharp and could result in cutting injuries.

NOTICE

Never put any objects into the air inlet or outlet.
Objects touching the fan at high operating speed can
be dangerous.

Never press the button of the user interface with a
hard, pointed object. The user interface may be
damaged.

Never pull or twist the electric wire of the user
interface. It may cause the unit to malfunction.

Never inspect or service the unit by yourself. Ask a
qualified service person to perform this work.

Do not use the air conditioner for other purposes. In
order to avoid any quality deterioration, do not use the
unit for cooling precision instruments, food, plants,
animals or works of art.

After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in
injury.

Do not place items which might be damaged by
moisture under the indoor unit. Condensation may
form if the humidity is above 80%, if the drain outlet is
blocked or the filter is polluted.

Arrange the drain hose to ensure smooth drainage.
Incomplete drainage may cause wetting of the
building, furniture etc.

Do not place the controller exposed to direct sunlight.
The LCD display may get discoloured, failing to
display the data.

Do not wipe the controller operation panel with
benzine, thinner, chemical dust cloth, etc. The panel
may get discoloured or the coating peeled off. If it is
heavily dirty, soak a cloth in water-diluted neutral
detergent, squeeze it well and wipe the panel clean.
Wipe it with another dry cloth.

Do not operate the air conditioner when using a room
fumigation-type insecticide. This could cause the
chemicals to become deposited in the unit, which
could endanger the health of those who are
hypersensitive to chemicals.
