Before Installation - Daikin FXDQ-M Engineering Data

EDUS39-600-F2_a
Improper positioning of the electrical parts box lid may
result in electric shocks, fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• Be sure to establish an ground.
Do not ground the unit to a utility pipe, arrester, or tele-
phone.
Incomplete ground may cause electrical shock, or fire.
• Do not remove the front panel because some parts
inside are dangerous to touch. In addition, some parts
may be damaged.
For checking and adjusting internal parts, contact your
dealer.
• Do not put a finger or other objects into the air inlet or
air outlet.
The fan is rotating at high speed and will cause injury.
• Do not let the indoor unit get wet as it may cause an
electric shock or fire.
• Placing a flower vase or other containers with water or
other liquids on the unit could result in a shock hazard
or fire if a spill occurs.
• A high surge current from lightning or other sources
may cause damage to the air conditioner.
• Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric
shock.
• Be sure to install ground for a leakage breaker.
Failure to install ground for a leakage breaker may result in
electric shocks, or fire.
• Do not install the air conditioner in the following loca-
tions:
(a) Where a mineral oil mist or an oil spray or vapor is pro-
duced, for example in a kitchen as plastic parts may deteri-
orate and fall off or result in water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is pro-
duced as corroding copper pipes or soldered parts may
result in refrigerant leakage.
(c) Near machinery emitting electromagnetic waves as
electromagnetic waves may disturb the operation of the
control system and result in a malfunction of the equipment.
• Heat exchanger fins are sharp enough to cut.
To avoid injury wear gloves or cover the fins when working
around them.
Use of unspecified parts could lead to the unit falling,
leaks and, in worse cases, electric shock or fire.
• Entrust installation to the place of purchase or a qual-
ified serviceman.
Improper installation could lead to leaks and, in worse
cases, electric shock or fire.
• Refrigerant pipes may be very hot or very cold during,
or immediately after, operation.
Touching them can result in burns or frostbite. To avoid
injury give the pipes time to return to normal temperature
or, if you must touch them, be sure to wear proper gloves.
CAUTION
• While following the instructions in this installation
manual, install drain piping in order to ensure proper
drainage and insulate piping in order to prevent con-
densation.
FXDQ-M
Improper drain piping may result in water leakage and
property damage.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use
any PP bands for a means of transportation. It is danger-
ous.
• Do not turn off the power immediately after stopping
operation.
Always wait at least five minutes before turning off the
power as water leakage or other problems may occur.
• Make sure to provide adequate measures to prevent
the outdoor unit from being used as a shelter by small
animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke, or fire. Please instruct the cus-
tomer to keep the area around the unit clean.
NOTE
• Install the indoor and outdoor units, power supply wir-
ing, and connecting wires at least 3.5 feet away from
televisions or radios in order to prevent image interfer-
ence or noise.
(Depending on the radio waves, a distance of 3.5 feet may
not be sufficient to eliminate the noise.
• Remote controller (wireless kit) transmitting distance
is shorter than expected in rooms with electronic fluo-
rescent lamps. Install the indoor unit as far away from
fluorescent lamps as possible.
• Dismantling of the unit, and treatment of the refriger-
ant, oil, and other parts, should be done in accordance
with local and national regulations.

BEFORE INSTALLATION

WARNING
• Entrust installation to the place of purchase or a qualified
serviceman. Improper installation or using unspecified
parts can result in the unit falling, leaks, electric shock, or
fire.
• Use of unspecified parts could lead to the unit falling, leaks
and, in worse cases, electric shock or fire.
NOTE
• Be sure to read this manual before installing the indoor unit.
• Be sure to mount an air filter (part to be procured in the field)
in the suction air passage in order to prevent water leaking,
or other problems.
The accessories needed for installation must be retained
in your custody until the installation work is completed.
Do not discard them!
1. Decide upon a line of transport.
2. Leave the unit inside its packaging until reaching the
installation site. If unpacking is unavoidable, use a sling of
soft material or protective plates, and a rope if lifting, to
avoid damage or scratches to the unit.
When moving the unit while removing it from the packing
case, be sure to lift it by the four hanger brackets. Avoid
putting any pressure on other parts, especially the refrig-
erant piping.
