•
Heat exchanger fins are sharp enough to cut.
To avoid injury wear glove or cover the fins when working
around them.
•
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 turning off the power.
Otherwise, water leakage may occur.
•
Do not use a charging cylinder. Using a charging cylinder may
cause the refrigerant to deteriorate.
•
Refrigerant R410A in the system must be kept clean, dry, and
tight.
(a) Clean and Dry -- Foreign materials (including mineral oils
such as SUNISO oil or moisture) should be prevented from
getting into the system.
(b) Tight -- R410A does not contain any chlorine, does 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. There-
fore take proper measures to check for the tightness of the
refrigerant piping installation. Read the chapter Refrigerant
Piping and follow the procedures.
•
Since R410A is a blend, the required additional refrigerant 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 (wireless kit) transmitting distance can be
shorter than expected in rooms with electronic fluorescent
lamps (inverter or rapid start types). Install the indoor unit far
away from fluorescent lamps as much as possible.
•
Indoor units are for indoor installation only. Outdoor units can
be installed either outdoors or indoors.
•
Do not install the air conditioner in the following locations:
(a) Where a mineral oil mist or oil spray or vapor is produced,
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 pro-
duced.
Corroding copper pipes or soldered parts may result in
refrigerant leakage.
(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 carbon fiber,
or ignitable dust suspension in the air, or where volatile
flammables such as thinner or gasoline are handled. Oper-
ating the unit in such conditions can cause a fire.
•
Take adequate measures to prevent the outdoor unit from being
used as a shelter by small animals. Small animals making con-
tact with electrical parts can cause malfunctions, smoke, or
fire. Instruct the customer to keep the area around the unit
clean.
NOTE
•
Install the power supply and control wires for the indoor and
outdoor units at least 3.5 feet away from televisions or radios to
prevent image interference or noise.
Depending on the radio waves, a distance of 3.5 feet may not be
sufficient to eliminate the noise.
•
Dismantling the unit, treatment of the refrigerant, oil and addi-
tional parts must be done in accordance with the relevant local,
state, and national regulations.
•
Do not use the following tools that are used with conventional
refrigerants: gauge manifold, charge hose, gas leak detector,
reverse flow check valve, refrigerant charge base, vacuum
gauge, or refrigerant recovery equipment.
•
If the conventional refrigerant and refrigerator oil are mixed in
R410A, the refrigerant may deteriorate.
•
This air conditioner is an appliance that should not be accessi-
ble to the general public.
•
The wall thickness of field-installed pipes should be selected in
accordance with the relevant local, state, and national regula-
tions.
