Daikin CXTQ36TASBLUA Installation Manual page 3

• This equipment can be installed with a Ground-Fault Cir-
cuit Breaker (GFCI). Although this is a recognized mea-
sure for additional protection, with the grounding sys-
tem in North America, a dedicated GFCI is not required.
• When installing or relocating the system, keep the refriger-
ant circuit free from substances (such as air) other than the
specified refrigerant (R-410A). Any presence of air or other
foreign substance in the refrigerant circuit can cause an ab-
normal 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
specified by Daikin are used, fire or explosion may occur.
• Do not touch the switch with wet fingers. Touching
switch with wet fingers can cause electric shock.
• To prevent injury, children should never play on or
around the unit.
• 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
flowing 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 tem-
perature 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 dam-
age.
• Insulate piping to prevent condensation.
• Be careful when transporting the product.
• Do not use a charging cylinder. Using a charging cylin-
der may cause the refrigerant to deteriorate.
• Refrigerant R-410A in the system must be kept clean,
dry and tight.
(a) Clean and Dry — Foreign materials (including min-
eral oils such as SUNISO oil or moisture) should
be prevented from getting into the system.
(b) Tight — R-410A does not contain any chlorine, does
not destroy the ozone layer, and does not reduce
the earth's protection again harmful ultraviolet ra-
diation. R-410A can contribute to the greenhouse
effect if it is released. Therefore take proper mea-
sures to check for the tightness of the refrigerant
piping installation. Read the Refrigerant Piping
(section 5) and follow the procedures.
• Since R-410A is a blend, the required additional refrig-
erant must be charged in its liquid state. If the refriger-
ant is charged in a state of gas, its composition can
change and the system will not work properly.
The indoor unit is for R-410A. 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 fluo-
rescent 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. This
unit is for indoor use.
• Do not install the air conditioner or heat pump 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 produced. 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 mal-
function.
(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.
• Take adequate measures to prevent the outside unit from
being used as a shelter by small animals. Small animals
making contact with electrical parts can cause malfunc-
tions, smoke, or fire. Instruct the customer to keep the
area around the unit clean.
• 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. Depend-
ing on the radio waves, a distance of 3.5 feet may not be
sufficient to eliminate the noise.
• When dismantling the unit, treatment of the refrigerant,
oil and additional parts must be done in accordance with
the relevant local, state and national regulations.
• Do not use the following tools that have been previously
used with conventional refrigerants: gauge manifold,
charge hose, gas leak detector, reverse flow check valve,
refrigerant charge base, vacuum gauge or refrigerant re-
covery equipment.
• If the conventional refrigerant and refrigerator oil are
mixed in R-410A, the refrigerant may deteriorate.
• This air conditioner or heat pump is an appliance that
should not be accessible to the general public.
• As design pressure is 450 psi, the wall thickness of field-
installed pipes should be selected in accordance with
the relevant local, state and national regulations.
