Make sure that all wiring is secured, that specifi ed wires
•
are used, and that no external forces act on the terminal
connections or wires. Improper connections or installa-
tion may result in fi re.
When wiring, position the wires so that the control box
•
cover can be securely fastened. Improper positioning of
the control box cover may result in electric shocks, fi re, or
the terminals overheating.
Before touching electrical parts, turn off the unit.
•
It is recommended to install a ground fault circuit inter-
•
rupter if one is not already available. This helps prevent
electrical shocks or fi re.
Securely fasten the outdoor unit terminal cover (panel).
•
If the terminal cover/panel is not installed properly, dust
or water may enter the outdoor unit causing fi re or
electric shock.
When installing or relocating the system, keep the
•
refrigerant circuit free from substances other than the
specifi ed refrigerant (R410A) such as air. Any presence
of air or other foreign substance in the refrigerant cir-
cuit can cause an abnormal pressure rise or rupture,
resulting in injury.
Do not change the setting of the protection devices. If
•
the pressure switch, thermal switch, or other protection
device is shorted and operated forcibly, or parts other
than those specifi ed by Daikin are used, fi re or explo-
sion may occur.
Heat exchanger fi ns are sharp enough to cut.
•
To avoid injury wear glove or cover the fi ns when work-
ing around them.
CAUTION
Do not touch the switch with wet fi ngers. Touching a
•
switch with wet fi ngers can cause electric shock.
Do not allow children to play on or around the unit to
•
prevent injury.
Do not touch the refrigerant pipes during and immedi-
•
ately after operation as the refrigerant pipes may be hot
or cold, depending on the condition of the refrigerant
fl owing through the refrigerant piping, compressor, and
other refrigerant cycle parts. Your hands may suffer
burns or frostbite if you touch the refrigerant pipes. To
avoid injury, give the pipes time to return to normal
temperature or, if you must touch them, be sure to wear
proper gloves.
Install drain piping to proper drainage. Improper drain
•
piping may result in water leakage and property damage.
Insulate piping to prevent condensation.
•
Be careful when transporting the product.
•
Do not turn off the power immediately after stopping
•
operation. Always wait for at least 5 minutes before turn-
ing off the power. Otherwise, water leakage may occur.
Do not touch the refrigerant pipes during and immedi-
•
ately after operation as the refrigerant pipes may be hot
or cold, depending on the condition of the refrigerant
fl owing through the refrigerant piping, compressor, and
other refrigerant cycle parts. Your hands may suffer
burns or frostbite if you touch the refrigerant pipes. To
avoid injury, give the pipes time to return to normal
temperature or, if you must touch them, be sure to wear
proper gloves.
Do not use a charging cylinder. Using a charging cylin-
•
der may cause the refrigerant to deteriorate.
Refrigerant R410A in the system must be kept clean,
•
dry, and tight.
Clean and Dry -- Foreign materials (including min-
(a)
eral oils such as SUNISO oil or moisture) should be
prevented from getting into the system.
Tight -- R410A does not contain any chlorine, does
(b)
not destroy the ozone layer, and does not reduce the
earth’s protection again harmful ultraviolet radiation.
R410A can contribute to the greenhouse effect if it is
released. Therefore take proper measures to check
for the tightness of the refrigerant piping installa-
tion. Read the chapter Refrigerant Piping work and
follow the procedures.
Since R410A is a blend, the required additional refriger-
•
ant must be charged in its liquid state. If the refrigerant
is charged in a state of gas, its composition can change
and the system will not work properly.
The indoor unit is for R410A. See the catalog for indoor
•
models that can be connected. Normal operation is not
possible when connected to other units.
Remote controller transmitting distance can be shorter
•
than expected in rooms with electronic fl uorescent
lamps (inverter or rapid start types). Install the indoor
unit far away from fl uorescent lamps as much as pos-
sible.
Install in a machine room that is free of moisture.
•
The unit is designed for indoor use.
Indoor units are for indoor installation only. Outdoor
•
units can be installed either outdoors or indoors. This
unit is for indoor use.
Do not install the air conditioner or heat pump in the
•
following locations:
Where a mineral oil mist or oil spray or vapor is
(a)
produced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in
water leakage.
Where corrosive gas, such as sulfurous acid gas, is
(b)
produced.
Corroding copper pipes or soldered parts may result
in refrigerant leakage.
Near machinery emitting electromagnetic waves.
(c)
Electromagnetic waves may disturb the operation of
the control system and cause the unit to malfunc-
tion.
Where fl ammable gas may leak, where there is
(d)
carbon fi ber, or ignitable dust suspension in the air,
or where volatile fl ammables such as thinner or
gasoline are handled. Operating the unit in such
conditions can cause a fi re.
