Before Installation - Daikin RZVF50 Installation Manual

• Earth the air conditioner.
Do not connect the earth wiring to gas or water piping,
lightning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.
• Be sure to install an earth leakage breaker.
Failure to do so may cause electric shocks and a fire.
• Disconnect the power supply before touching the electric
components.
If you touch the live part, you may get electric shocks.
• Make sure that all wiring is secure, using the specified
wirings and ensuring that external forces do not act on the
terminal connections or wirings.
Incomplete connection or fixing may cause an overheat or a
fire.
• When wiring between the indoor and outdoor units, and
wiring the power supply, form the wirings orderly so that the
control box lid can be securely fastened.
If the control box lid is not in place, overheating of the
terminals, electric shocks or a fire may be caused.
• If refrigerant gas leaks during installation work, ventilate the
area immediately.
Toxic gas may be produced if refrigerant gas comes into
contact with a fire.
• After completing the installation work, check to make sure
that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the
room and comes into contact with a source of a fire, such as
a fan heater, stove or cooker.
• Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
• When installing or relocating the air conditioner, be sure to
bleed the refrigerant circuit to ensure it is free of air, and
use only the specified refrigerant (R32).
The presence of air or other foreign matter in the refrigerant
circuit causes abnormal pressure rise, which may result in
equipment damage and even injury.
• Do not allow children to climb on the outdoor unit and avoid
placing objects on the unit.
Injury may result if the unit becomes loose and falls.
• When flared joints are reused indoors, the flare part shall be
re-fabricated.
-�CAUTION------------
• Install drain piping according to this installation manual to
ensure good drainage, and insulate the piping to prevent
condensation.
Improper drain piping may cause water leakage, make the
furniture get wet.
• Install the air conditioner, power supply wiring, remote
controller wiring and transmission wiring at least 1 meter
away from televisions or radios to prevent image interference
or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient to eliminate the noise.)
• Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic lighting
type (inverter or rapid start type) fluorescent lamp is installed.
• Do not install the air conditioner in places such as the
following:
1. Where there is mist of oil, oil spray or vapour for example
a kitchen.
Resin parts may deteriorate, and fall out or water may leak.
2. Where corrosive gas, such as sulfurous acid gas, is
produced.
Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.
3. Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
4. Where flammable gases may leak, where carbon fibre
or ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
If the gas should leak and remain around the air
conditioner, it may cause ignition.
• The air conditioner is not intended for use in a potentially
explosive atmosphere.
• Pay careful attention when transporting the product.
Carry the product by the handle sections indicated on the
packaging material.
Do not hold the PP band since the PP band can become
loose and may result in danger.
• Do not touch the heat exchanger fins.
Inadvertently touching the fins can cause injury.
• Make sure to provide for adequate measures in order to
prevent that the outdoor unit be used as a shelter by small
animals.
Small animals making contact with electrical parts can cause
malfunctions, smoke or fire. Please instruct the customer to
keep the area around the unit clean.
• Install in a machine room that is free of moisture.
The unit is designed for indoor use.
• The refrigerant R32 requires that strict precautions be
observed for keeping the system clean, dry and tightly
sealed.
- Clean and dry
Strict measures must be taken to keep impurities
(including SUNISO oil and other mineral oils as well as
moisture) out of the system.
- Tightly sealed
R32 contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth's protection against
harmful ultraviolet radiation.
R32 will contribute only slightly to the greenhouse effect
if released into the atmosphere.
• Only qualified personnel can handle, fill, purge and dispose
of the refrigerant.
• Disposal requirements
- Dismantling of the unit, treatment of the refrigerant, of oil
and of other parts must be done in accordance with relevant
local and national legislation.

2. BEFORE INSTALLATION

When unpacking the indoor unit or moving the unit after
unpacked, hold the hangers (4 places) and do not apply
force to other parts (particularly refrigerant piping, drain
piping).
• Make sure to check in advance that the refrigerant to be
used for installation work is R32.
(The air conditioner will not properly operate if a wrong
refrigerant is used.)
• For installation of the outdoor unit, refer to the installation
manual attached to the outdoor unit.
• Do not throw away the accessories until the installation work
is completed.
• 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.
