1. SAFETY CAUTIONS
Read the following cautions carefully and
use your equipment properly.
There are two kinds of safety cautions and tips listed
here as follows:
WARNING ....... Improper handling can lead to
such serious consequences as
death or severe injury.
CAUTION ........ Improper handling can lead to
injury or damage. It could also
have serious consequences
under certain conditions.
NOTE
Keep this operation manual handy so that you
can refer to them if needed.
Also, if this equipment is transferred to a new user,
make sure to hand over this operation manual to the
new user.
WARNING
It is not good for your health to expose your
body to the air flow for a long time.
In order to avoid electric shock, fire or injury,
or if you detect any abnormality such as smell
of fire, turn off power and call your dealer for
instructions.

Operation manual
Ask your dealer to install in a machine room
that has no water drops by raining.
This unit is for indoor use.
Incomplete installation performed by yourself may
result in a water leakage, electric shock, and fire.
Ask your dealer for improvement, repair, and
maintenance.
Incomplete improvement, repair, and maintenance
may result in a water leakage, electric shock, and
fire.
Do not put a finger, a rod or other objects into
the air inlet or outlet. As the fan is rotating at
high speed, it will cause injury.
Never touch the air outlet or the horizontal
blades while the swing flap is in operation.
Fingers may become caught or the unit may break
down.
The refrigerant in the air conditioner is safe
and normally does not leak. If the refrigerant
leaks inside the room, the contact with a fire of
a burner, a heater or a cooker may result in a
harmful gas.
Turn off any combustible heating devices, ventilate
the room, and contact the dealer where you purchased the unit.
Do not use the air conditioner until when a service
person confirms to finish repairing the portion
where the refrigerant leaks.
For refrigerant leakage, consult your dealer.
When the air conditioner is to be installed in a
small room, it is necessary to take proper measures so that the amount of any leaked refrigerant
does not exceed the limiting concentration even
when it leaks. If the refrigerant leaks exceeding the
level of limiting concentration, an oxygen deficiency accident may happen.
Improper installation or attachment of equipment or accessories could result in electric
shock, short-circuit, leaks, fire or other damage to the equipment. Be sure only to use
accessories made by Daikin which are specifically designed for use with the equipment and
have them installed by a professional.
Ask your dealer to move and reinstall the air
conditioner.
Incomplete installation may result in a water leakage, electric shock, and fire.
In order to avoid electric shock, fire, injury or
damaging the unit, do not use improper
ampere fuses or do not use copper nor steel
wires instead.

6. OPTIMUM OPERATION
7. MAINTENANCE
Observe the following precautions to ensure the
system operates properly.
7-1 HANDLING OF HEAT SOURCE WATER
• Adjust the air outlet properly and avoid direct air
flow to room inhabitants.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or
cooling.
• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
• Ventilate often.
Extended use requires special attention to ventilation.
• Do not keep doors and windows opened. If the
doors and windows remain open, air will flow out
of your room causing a decrease in the cooling or
heating effect.
• Never place objects near the air inlet or the air
outlet of the unit. It may cause deterioration in the
effect or stop the operation.
• Turn off the main power supply switch to the unit
when the unit is not used for longer periods of
time. If the switch is on, it uses electricity. Before
restarting the unit, turn on the main power supply
switch 6 hours before operation to protect the unit.
(Refer to the chapter “Maintenance” in the indoor
unit manual.)
• When the display shows “
” (time to clean the
air filter), ask a qualified service person to clean
the filters. (Refer to the chapter “Maintenance” in
the indoor unit manual.)
• Keep the indoor unit and remote control at least
1 m away from televisions, radios, stereos, and
other similar equipment.
Failing to do so may cause static or distorted pictures.
• Do not use other heating devices directly beneath
the indoor unit.
If you do, they might get deformed by the heat.
• It takes time for the room temperature to reach the
set temperature.
We recommend starting the operation in advance
using timer operation.
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the air flow direction parallel during cooling or
dry operation, and set it downwards during heating operation. Do not let the air blow directly to a
person.
• Make sure that the inlet and outlet of the indoor
unit are not clogged.
English
Requests from manufacturer;
• Do not fail to mount a strainer (sold separately as
an accessory) in the inlet pipe for heat source
water intake.
• Do not use any water contaminated by relatively
high level of foreign materials for heat source.
• Carry out the control of water quality without fail.
Otherwise, corrosion of condenser or piping
occurs or germs may be generated.
• For the timing of cleaning and its method, consult
with the dealer you purchased the unit.
Cleaning of the heat-exchanger on the water
side
• Water scales, mosses, etc will accumulate on the
heat-exchanger on the water side within an airconditioner during use for a long period. Carry out
cleaning at a regular interval. If water scales,
mosses, etc. have accumulated, the cooling and
heating capacity may decline. The safety device
will be repeatedly actuated causing normal operation to become impossible.
• For use in an area where the water quality is poor,
increase the frequency of cleaning.
Cleaning of strainer
• Clean the strainer in the inlet pipe of heat source
water intake.
7-2 AT THE BEGINNING OF THE SEASON
Check
• Are the inlet and outlet of the indoor unit blocked?
Remove anything blocking them.
• Run the pump and make sure that the water is circulating.
If you operate without water circulating, the unit
may be damaged.
Clean the air filter and exterior.
• After cleaning the air filter, be sure to put it back in
the same position.
See the operation manual included with the
indoor unit for details on how to clean it.
Turn the power on.
• When the power comes on, the characters in the
remote controller display appear.
(To protect the unit, turn the power on at least
6 hours before operating. This makes starting
operation smooth.)
8
01_EN_3P153897-1.fm Page 9 Wednesday, March 2, 2005 3:32 PM
7-3 AT THE END OF THE SEASON
On a clear day, use fan operation for around half a
day to thoroughly dry out the interior of the unit.
• Refer to page 5 for details on fan only operation.
conditioner, and this prevents communication
between the units, causing them to stop.
Operation automatically restarts when the noise
goes away.
Turn off the power.
• When the power is shut off, the characters in the
remote controller display disappear.
• When the power is on, the unit consumes up to
several dozen Watts of power.
Turn off the power to conserve energy.
8-3 COOL/HEAT CANNOT BE CHANGED
OVER
Clean the air filter and exterior.
• After cleaning the air filter, be sure to put it back in
the same position.
See the operation manual included with the
indoor unit for details on how to clean it.
• If the water piping may freeze, keep operating the
heat source water pump operating even during
the unit stops.
• Remove all the water from the unit and the water
piping if the pump is not used for a long time in
winter.
• When the cool/heat selector switch is
”
installed and the display shows “
(changeover under control).
This is because cool/heat changeover is controlled by the cool/heat selector. Ask your Daikin
dealer where the remote control switch is installed.
8. FOLLOWING SYMPTOMS ARE NOT
AIR CONDITIONER TROUBLES
8-1 THE SYSTEM DOES NOT OPERATE
• The air conditioner does not start immediately
when restarting the operation after stoping
the operation or when putting the temperature
back after changing the temperature setting
with the temperature adjust button.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the unit, the air conditioner starts 5 minutes after it is turned ON again
in case it was turned OFF just before.
• If “Centralized Control” is displayed on the
remote controller and pressing the operation
button causes the display to blink for a few
seconds.
This indicates that the central device is controlling
the unit.
The blinking display indicates that the remote
control cannot be used.
• The system does not start immediately after
the power supply is turned on.
Wait one minute until the micro computer is prepared for operation.
8-2 IT STOPS SOMETIMES
• The remote controller display reads “U4” or
“U5” and stops but then restarts after a few
minutes.
This is because the remote control is intercepting
noise from electrical appliances other than the air
9
• When the display shows “
”
(changeover under control).
It shows that this is a slave remote controller.
Refer to “Setting the master remote controller”.
8-4 FAN OPERATION IS POSSIBLE, BUT
COOLING AND HEATING DO NOT
WORK
• Immediately after the power is turned on.
The micro computer is getting ready to operate.
Wait 10 minutes.
• Only fan operation is possible.
This is because the interlock contact point is not
turned on. (Check that the water pump is operating.)
This is because the inlet temperature (*1) of the
heat source water is beyond the operating conditions (refer to page 4). (Check that it is in the
range of the operating conditions.)
8-5 THE FAN SPEED DOES NOT CORRESPOND TO THE SETTING
• The fan speed does no change even if the fan
strength adjustment button in pressed.
• When the room temperature reaches the set temperature during heating operation (extremely low
fan speed operation).
• When operation is changed to fan operation while
another indoor unit is in heating operation
(extremely low fan speed operation).
• When the remote controller displays “
”
(stoppage).
• When the remote controller displays “
” (automatic operation).
8-6 THE AIR FLOW DIRECTION DOES NOT
CORRESPOND TO THE SETTING
• The air flow direction does not correspond to
the remote control display.
The air flow direction does not swing.
This is because the unit is being controlled by the
microcomputer. Refer to “Adjusting the air flow
direction”.
English
01_EN_3P153897-1.fm Page 10 Wednesday, March 2, 2005 3:32 PM
8-7 WHITE MIST COMES OUT OF A UNIT
8-9
Indoor unit
• When the unit is used after stopping for a long
time.
This is because dust attached inside the indoor
unit spouts out.
• When humidity is high during cooling operation.
If the interior of an indoor unit is extremely contaminated, the temperature distribution inside a
room becomes uneven. (*2) It is necessary to
clean the interior of the indoor unit. Ask your
Daikin dealer for details on cleaning the unit. This
operation requires a qualified service person.
• Immediately after the cooling operation stops
and if the room temperature and humidity are
low.
This is because warm refrigerant gas flows back
into the indoor unit and generates steam.
8-8 NOISE OF AIR CONDITIONERS
Indoor unit
• A “zeen” sound is heard immediately after the
power supply is turned on.
The electronic expansion valve inside an indoor
unit starts working and makes the noise. (*3) Its
volume will reduce in about one minute.
• A continuous low “shah” sound is heard when
the system is in cooling operation or at a stop.
When the drain pump (optional accessories) is in
operation, this noise is heard.
• A “pishi-pishi” squeaking sound is heard when
the system is in heating operation and at a
stop.
Expansion and contraction of plastic parts caused
by temperature change make this noise.
• A low “sah”, “choro-choro” sound is heard
while the indoor unit is stopped.
When the other indoor unit is in operation, this
noise is heard. In order to prevent oil and refrigerant from remaining in the system, a small amount
of refrigerant is kept flowing.
Outside unit
DUST COMES OUT OF THE UNIT
8-10 THE UNITS CAN GIVE OFF ODOURS
• During operation.
The unit can absorb the smell of rooms, furniture,
cigarettes, etc., and then emit it again. (*2)
It is necessary to clean the interior of the indoor
unit. Ask your Daikin dealer for details on cleaning
the unit. This operation requires a qualified service person.
8-11 THE DISPLAY SHOWS “
”
• This is the case immediately after the main
power supply switch is turned on.
This means that the remote controller is in normal
condition. This continues for one minute at maximum.
8-12 THE UNIT DOES NOT STOP
• JUST AFTER THE OPERATION STOPS
This is to prevent oil and refrigerant from remaining in the outside unit.
The unit will stop after 5 to 10 minutes.
8-13 THE COMPRESSOR IN THE OUTSIDE
UNIT DOESN’T STOP
• JUST AFTER THE OPERATION STOPS
This is to prevent oil and refrigerant from remaining in the outside unit.
The unit will stop after 5 to 10 minutes.
8-14 THE UNIT IS WARM
• WHEN THE UNIT STOPS
This is because the crankcase heater is warming
the compressor so that the compressor can start
smoothly.
• When the tone of operating noise changes.
This noise is caused by the change of frequency.
8-15 HOT AIR IS EMITTED EVEN THOUGH
THE UNIT IS STOPPED
Indoor unit, outside unit
• Hot air can be felt when the unit is stopped.
Several different indoor units are being run on the
same system, so if another unit is running, some
refrigerant will still flow through the stopping unit.
• A continuous low hissing sound is heard
when the system is in cooling or heating operation.
This is the sound of refrigerant gas flowing
through both indoor unit and outside unit.
• A hissing sound which is heard at the start or
immediately after stopping operation.
This is the noise of refrigerant gas caused by flow
stop or flow change.
English
8-16 DOES NOT COOL VERY WELL
• Program dry operation.
Program dry operation is designed to lower the
room temperature as little as possible.
Refer to page 5.
*1 The Ve-up II W Series performs air conditioning by using a heat transfer with the cold water
sent from the boiler or solar panel system.
This is the cold water being spoken about.

[NOTES]
(1) The circle marks in the columns for corrosion or
scale to develop.
English
(2) Corrosion has a tendency to occur when water
temperature is high (40°C or higher), and if metals with no protective coating whatever are
directly exposed to water, it would be a good
idea to take effective measures against corrosion such as adding a corrosion inhibitor or
deaeration treatment.
(3) In a condenser water circuit that uses a closed
cooling tower, the closed circuit circulating water
and make-up water must satisfy its water quality
standards for the hot water system, and passing
water and make-up water must satisfy those for
the circulation type cooling water system.
(4) Supply or make-up water should be tap water
(clean water), industrial water and underground
water except for purified water, neutral water and
softened water or the like.
(5) The fifteen items in the table above represent
typical causes of corrosion and scale.
(6) Passing water may cause corrosion.
Do not use passing water.
After-sales service:
WARNING
• Do not disassemble, modify or repair the unit.
This may cause water leakage, electric shock or
fire.
Contact your dealer.
• If the refrigerant leaks, keep out of fire.
Although the refrigerant does not usually leak, if
the refrigerant leaks out into a room and comes in
contact with the combustible air in the equipment
such as fan heater, stove, oil (gas) cooker, etc., it
will cause toxic gas to be generated.
When a refrigerant leakage failure has been
repaired, confirm a service person that
the leakage point has been corrected
surely before restarting operation.
• Do not remove or reinstall the unit by yourself.
Incorrect installation may cause water leakage,
electrical shock or fire.
Contact your dealer.
• When asking your dealer to repair, inform
related staff of the details as follows:
• Model name and product No. of air conditioner:
Refer to the warranty card.
• Shipping date and installation date:
