2. Safety considerations
The precautions here, all cover very important topics, so be sure to
follow them carefully.
All activities described in this manual shall be carried out by an
installer.
Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses, …) when performing installation,
maintenance or service to the unit.
If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.
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, optional
equipment and spare parts made by Daikin which are specially
designed for use with the products as of subject in this manual and
have them installed by an installer.
Warning
Ask your dealer or qualified personnel to carry out installation
work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.
Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.
The equipment is not intended for use in a potentially explosive
atmosphere.
Consult your local dealer regarding what to do in case of
refrigerant leakage. When the unit 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
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.
Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.
Install the unit on a foundation that can withstand its weight.
Insufficient strength may result in the fall of equipment and
causing injury.
Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.
Make sure that all electrical work is carried out by qualified
personnel according to the applicable legislation and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheating of the terminals,
electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
When planning to relocate former installed units, you must first
recover the refrigerant after the pump down operation. Refer to
chapter "13. Pump down operation" on page 12.
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
Be sure to install an earth leakage circuit breaker in accordance
with applicable legislation. Failure to do so may cause electrical
shock and fire.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.

3. Before installation
3.1. Scope of this manual
This manual describes the procedures for handling, installing and
connecting AZQS100~140B units.
3.2. Precautions
Check the following if the ground-fault circuit interrupter is triggered:
Make sure that the interrupter is compatible with high
frequencies.
This unit has an inverter, so an interrupter capable of handling
high frequencies is needed to prevent malfunction of the
interrupter itself.
3.3. Precautions for R410A
The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.
-Tight
Read "9. Precautions on refrigerant piping" on page 8 carefully
and follow these procedures correctly.
Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).
The connected indoor units must be indoor units designed
exclusively for R410A.
CAUTION
Since maximum working pressure is 4.0 MPa or 40 bar,
pipes of larger wall thickness may be required. Refer to
paragraph "8.1. Selection of piping material" on page 7.
NOTICE: Insulation resistance of the compressor
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance can drop, but if it is
at least 1 M, then the machine will not break down.
Turn the power on and leave it on for six hours. Then,
check if the insulation resistance of the compressor
has risen or not.
The compressor will heat up and evaporate any
refrigerant in the compressor.

the side of the casing, otherwise the casing could be deformed.
5. Selecting installation site
5.1. General
Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.
- Places where there is no possibility of flammable gas or
product leak.
- The equipment is not intended for use in a potentially
explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.
- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).
- Places where the rain can be avoided as much as possible.
- Do not install the unit in places often used as work place.
In case of construction works (e.g. grinding works) where a
lot of dust is created, the unit must be covered.
- Do not place any objects or equipment on top of the unit (top
plate).
- Do not climb, sit or stand on top of the unit,
- Be sure that sufficient precautions are taken, in accordance
with applicable legislation, in case of refrigerant leakage.
When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
- Deterioration of the operational capacity.
- Frequent frost acceleration in heating operation.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.

Install a baffle plate on the air suction side of the outdoor unit
and set the outlet side at a right angle to the direction of the
wind:
Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).
If you install the unit on a frame, please install a waterproof plate
(field supply) within 150 mm of the underside of the unit in order
to prevent the invasion of water from the lower direction.
When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
If you install the unit on a building frame,
please install a waterproof plate (field
supply)(within 150 mm of the underside of
the unit) or use a drain kit in order to avoid
the drainwater dripping (field supply). (See
figure).
Make sure that the unit is installed level.
5.2. Selecting a location in cold climates
To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
Never install the outdoor unit at a site where the suction side
may be exposed directly to wind.
To prevent exposure to wind, install a baffle plate on the air
discharge side of the outdoor unit.
In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit and set the
outlet side at a right angle to the direction of the wind:
6. Precautions on installation
6.1. Foundation work
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)
It is best to screw in the foundation bolts
until their length are 20 mm from the
foundation surface.
Fix the outdoor unit to the foundation bolts using nuts
with resin washers (1) as shown in the figure.
If the coating on the fastening area is stripped off, the nuts rust
easily.

6.3. Drain pipe disposal
Make sure the drain works properly.
In regions where buildups of snow can be expected, the
accumulation and freezing of snow in the space between the
heat exchanger and external plate may lower operating
efficiency. In this case, drill a knock-out hole in the lower part of
the bottom frame so the snow can escape. When creating a
knock-out hole, use a Ø6 mm drill bit to open round holes
connected to the circumference of the knock-out hole (4 places).
After punching the knock-out hole, the application of repair-type
paint on the surface around the edge sections is recommended
to prevent rust.
7. Installation service space
The installation service spaces shown in the illustrations are
based on an air intake temperature of 35°C (DB) for COOL
operation. In regions where the air intake temperature regularly
exceeds 35°C (DB), or if the heat load of outdoor units is
expected to regularly exceed the maximum operating capacity,
reserve a larger space than that indicated at the air intake side
of units.
Regarding the required air outlet space, position the units with
consideration to the space required for the onsite refrigerant
piping work as well. Consult your dealer if the work conditions do
not match those in the drawings.
7.1. Precaution on installation
(A) In case of non-stacked installation (See figure 1) (Unit : mm)
(A-1) Single unit installation
(A-2) Multiple units installation (2 units or more)
- Secure appropriate space when using a side piping outlet.
(B) In case of stacked installation
1. In case obstacles exist in front of the outlet side.
2. In case obstacles exist in front of the air inlet.
Do not exceed two levels for stacked installation.
Install a roof cover as shown in the figures above (field supply),
as outdoor units with downward drainage are subject to dripping
and freezing of that drain water.
Install the upper outdoor unit so that its bottom plate is at
sufficient height above the roof cover. This is to prevent the
buildup of ice on the bottom plate outer surface. A space of at
least 500 mm is recommended.
It is not necessary to install a roof cover if there is no danger of
drainage dripping and freezing. In this case, the space between
the upper and lower outdoor units should be at least 100 mm.
Close the gap between the upper and lower units so there is no
re-intake of discharged air.

8.1. Selection of piping material
Construction material: phosphoric acid deoxidised seamless
copper for refrigerant.
Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.
The pipe thickness of the refrigerant piping should comply with
relevant local and national regulations. The minimal pipe
thickness for R410A piping must be in accordance with the table
below.
Only use annealed material for flare connections.
8.2. Refrigerant pipe size
The pipes should have the same size as the outdoor connections.
8.3. Allowable pipe length and height difference
See the table below concerning lengths and heights.
L A
LHL1/2H 250

H<L Installation impossible
DANGER
Piping and other pressure containing parts shall
comply with the applicable legislation and shall be
suitable for refrigerant. Use phosphoric acid
deoxidised seamless copper for refrigerant.
Installation shall be done by an installer, the choice of
materials and installation shall comply with applicable
legislation. In Europe the EN378 is the application
standard that shall be used.
NOTICE
To persons in charge of piping work:
Be sure to open the stop valve after piping installing and
vacuuming is complete. (Running the system with the
valve closed may break the compressor.)
INFORMATION
It is forbidden to discharge refrigerant into the atmosphere.
Collect the refrigerant in accordance with the freon
collection and destruction law.
NOTICE
Do not use flux when brazing the refrigerant piping.
For brazing, use phosphor copper brazing filler metal
(BCuP) which does not require a flux.
(If a chlorine flux is used, the piping will corrode, and if the
flux contains fluoride, it will cause the coolant oil to
deteriorate, adversely affecting the coolant piping system.

9. Precautions on refrigerant piping
Do not allow anything other than the designated refrigerant to
get mixed into the freezing cycle, such as air, etc. If any
refrigerant gas leaks while working on the unit, ventilate the
room thoroughly right away.
Use R410A only when adding refrigerant
Installation tools:
Make sure to use installation tools (gauge manifold, charge
hose, etc.) that are exclusively used for R410A installations to
withstand the pressure and to prevent foreign materials (e.g.
mineral oils and moisture) from mixing into the system.
Vacuum pump:
Use a 2-stage vacuum pump with a non-return valve
Make sure the pump oil does not flow oppositely into the system
while the pump is not working.
Use a vacuum pump which can evacuate to –100.7 kPa (5 Torr,
–755 mm Hg).
During tests never pressurize the appliances with a pressure
higher than the maximum allowable pressure (see unit name
plate: PS).
In order to prevent dirt, liquid or dust from entering the piping,
cure the piping with a pinch or taping.
Great caution is needed when passing copper tubes through
walls.
Piping should be mounted so that the flare is not subjected to
mechanical stress.
9.1. Flaring guidelines
Flares should not be re-used. New ones should be made in
order to prevent leaks.
Use a pipe cutter and flare tool suitable for the refrigerant used.
Only use the flare nuts included with the unit. Using different
flare nuts may cause the refrigerant to leak.
Please refer to the table for flaring dimensions and tightening
torques (too much tightening will result in splitting the flare).
When connecting the flare nut, coat the flare inner surface with
ether oil or with ester oil and initially tighten 3 or 4 turns by hand
before tightening firmly.
When loosening a flare nut, always use two wrenches together.
When connecting the piping, always use a spanner and torque
wrench together to tighten the flare nut to prevent flare nut
cracking and leaks.
1Torque wrench
2Spanner
3Piping union
4Flare nut
Not recommended, but in case of emergency
Should you be forced to connect the piping without a torque
wrench, follow the following installation method:
Tighten the flare nut using a spanner until the tightening
torque suddenly increases.
From that position further tighten the flare nut to the angle
listed below:
9.2. Brazing guidelines
Make sure to blow through with nitrogen when brazing.
Blowing through with nitrogen prevents the creation of large
quantities of oxidized film on the inside of the piping. An oxidized
film adversely affects valves and compressors in the
refrigerating system and prevents proper operation.
The nitrogen pressure should be set to 0.02 MPa (i.e., just
enough so it can be felt on the skin) with a pressure-reducing
valve. Refer to figure 2.
1Refrigerant piping
2Part to be brazed
3Taping
4Manual valve
5Pressure-reducing valve
6Nitrogen
Do not use anti-oxidants when brazing the pipe joints.
Residue can clog pipes and break equipment.
Do not use flux when brazing copper-to-copper refrigerant
piping. Use phosphor copper brazing filler alloy (BCuP) which
does not require flux.
Flux has an extremely harmful influence on refrigerant piping
systems. For instance, if chlorine based flux is used, it will cause
pipe corrosion or, in particular, if the flux contains fluorine, it will
deteriorate the refrigerant oil.
9.3. Stop valve operation
Cautions on handling the stop valve
Make sure to keep both stop valves open during operation.
The figure below shows the name of each part required in
handling the stop valve.
The stop valve is factory closed.

Do not apply excessive force to the valve stem. Doing so may
break the valve body.
Since the stop valve attachment plate may be deformed if only a
torque wrench is used to loosen or tighten the flare nut, always
make sure to secure the stop valve with a spanner, then loosen
or tighten the flare nut with a torque wrench.
Do not place the spanner on the stem cap, as this could cause a
refrigerant leak.
When it is expected that the operating pressure will be low (for
example, when cooling will be performed while the outside air
temperature is low), sufficiently seal the flare nut in the stop
valve on the gas line with silicon sealant to prevent freezing.
Opening/closing the stop valve
Opening the stop valve
1. Remove the valve cover.
2. Insert a hexagon wrench (liquid side: 4 mm/gas side: 6 mm) into
the valve stem and turn the valve stem counterclockwise.
3. When the valve stem cannot be turned any further, stop turning.
The valve is now open.
Closing the stop valve
1. Remove the valve cover.
2. Insert a hexagon wrench (liquid side: 4 mm/gas side: 6 mm) into
the valve stem and turn the valve stem clockwise.
3. When the valve stem cannot be turned any further, stop turning.
The valve is now closed.
Cautions on handling the stem cap
The stem cap is sealed where
indicated by the arrow. Take care not
to damage it.
After handling the stop valve, make
sure to tighten the stem cap securely.
For the tightening torque, refer to the
table below.
Check for refrigerant leaks after tightening the stem cap.
Cautions on handling the service port
Always use a charge hose equipped with a valve depressor pin,
since the service port is a Schrader type valve.
After handling the service port, make sure to tighten the service
port cap securely. For the tightening torque, refer to the table
below.
Check for refrigerant leaks after tightening the service port cap.

(Use a metal saw to cut out the slits.)
To install the connecting pipe to the unit in a downward
direction, make a knock-out hole by penetrating the centre area
around the knock-out hole using a Ø6 mm drill (4x). (See
figure "Field pipes in 4 directions".)
After knocking out the knock-out hole, it is recommended to
apply repair paint to the edge and the surrounding end surfaces
to prevent rusting.
When passing electrical wiring through the knock-out holes,
remove any burrs from the knock-out holes and wrap the wiring
with protective tape to prevent damage.

10.1. Preventing foreign objects from entering
Plug the pipe through-holes with putty or insulating material
(procured locally) to stop up all gaps, as shown in the figure.
1Putty or insulating material
(produced locally)
If there is any possibility that small animals
enter the system through the knock-out holes,
plug the holes with packing materials (field
supplied).
Insects or small animals entering the outdoor unit may cause a short
circuit in the electrical box.
Seal knock-out holes to avoid snow and humidity entering.
10.2. Precautions when connecting field piping and
regarding insulation
Be careful not to let the indoor and outdoor piping come into
contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.
When the outdoor unit is installed above the indoor unit the
following can occur:
The condensed water on the stop valve can move to the indoor
unit. To avoid this, please cover the stop valve with sealing
material.
If the temperature is higher than 30°C and the humidity is higher
than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
Be sure to insulate the liquid and gas-side field piping.
(The highest temperature that the gas-side piping can reach is
around 120°C, so be sure to use insulating material which is
very resistant.)
(See figure 3).

3Sealant, etc.
4Insulation material
AWind heat insulation material around the piping section so
it is not exposed and then cover the insulation material with
vinyl tape.
10.3. Cautions for necessity of a trap
To avoid the risk of oil held inside the riser piping flowing back into
the compressor when stopped and causing liquid compression
phenomenon, or cases of deterioration of oil return, it will be
necessary to provide a trap at each difference in height of 10 m in the
riser gas piping.

HInstall trap at each difference in height of 10 m.
A trap is not necessary when the outdoor unit is installed at
higher position than the indoor unit.
11. Leak test and vacuum drying
When all piping work is complete and the outdoor unit is connected to
the indoor unit, it is necessary to:
check for any leakages in the refrigerant piping
to perform vacuum drying to remove all moisture in the
refrigerant piping.
If there is a possibility of moisture being present in the refrigerant
piping (for example, rainwater may have entered the piping), first
carry out the vacuum drying procedure below until all moisture has
been removed.
11.1. General guidelines
All piping inside the unit has been factory tested for leaks.
Use a 2-stage vacuum pump with a non-return valve which can
evacuate to a gauge pressure of –100.7 kPa (5 Torr absolute,
–755 mm Hg).
Connect the vacuum pump to both the service port of the gas
stop valve and the liquid stop valve to increase efficiency.

11.3. Leak test
The leak test must satisfy specification EN378-2.
1Vacuum leak test
1.1 Evacuate the system from the liquid and gas piping to
–100.7 kPa (5 Torr).
1.2 Once reached, turn off the vacuum pump and check that
the pressure does not rise for at least 1 minute.
1.3 Should the pressure rise, the system may either contain
moisture (refer to the paragraph "Vacuum drying") or have
leaks.
2Pressure leak test
2.1 Break the vacuum by pressurizing with nitrogen gas to a
minimum gauge pressure of 0.2 MPa (2 bar).
Never set the gauge pressure higher than the maximum
operation pressure of the unit, i.e. 4.0 MPa (40 bar).
2.2 Test for leaks by applying a bubble test solution to all piping
connections.
2.3 Discharge all nitrogen gas.
NOTICE
Any exposed piping may cause condensation.
DANGER
Do not touch piping and internal parts.
1
NOTICE
Do not purge the air with refrigerants. Use a vacuum
pump to evacuate the installation. No additional
refrigerant is provided for air purging.
Make sure that the gas stop valve and liquid stop
valve are firmly closed before performing the leak test
or vacuum drying.
NOTICE
Make sure to use a recommended bubble test solution
from your wholesaler.
Do not use soap water, which may cause cracking of
flare nuts (soap water may contain salt, which absorbs
moisture that will freeze when the piping gets cold),
and/or lead to corrosion of flared joints (soap water
may contain ammonia which causes a corrosive effect
between the brass flare nut and the copper flare).

11.4. Vacuum drying
To remove all moisture from the system, proceed as follows:
1Evacuate the system for at least 2 hours to a target vacuum of
–100.7 kPa (= –1.007 bar).
2Check that, with the vacuum pump turned off, the target vacuum
is maintained for at least 1 hour.
3Should you fail to reach the target vacuum within 2 hours or
maintain the vacuum for 1 hour, the system may contain too
much moisture.
4In that case, break the vacuum by pressurizing with nitrogen gas
to a gauge pressure of 0.05 MPa (0.5 bar) and repeat steps 1to
3until all moisture has been removed.
5The stop valves can now be opened, and/or additional
refrigerant can be charged (see "12. Charging refrigerant" on
page 11).
12. Charging refrigerant
12.1. Important information regarding the refrigerant
used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type: R410A
GWP(1) value: 1975
(1) GWP = global warming potential
Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
+the total refrigerant charge
on the fluorinated greenhouse gases label supplied with the product.
The filled out label must be adhered on the inside of the product and
in the proximity of the product charging port (e.g. on the inside of the
service cover).
To avoid compressor breakdown, do not charge the refrigerant
more than the specified amount.
12.2. Precautions and general guidelines
When servicing the unit requires the refrigerant system to be
opened, treatment and evacuation of refrigerant must be done in
accordance with applicable legislation.
Refrigerant can not be charged until field wiring has been
completed.
Refrigerant may only be charged after performing the leak test
and vacuum drying (see "11. Leak test and vacuum drying" on
page 10).
This unit requires additional charging of refrigerant according to
the length of refrigerant piping connected at the site.
Make sure to charge the refrigerant in liquid state to the liquid
pipe. Since R410A is a mixed refrigerant, its composition
changes if charged in its gaseous state and normal system
operation would then no longer be assured.
Before charging, check whether the refrigerant cylinder has a
syphon attached or not and position the cylinder accordingly.
On this model it is not necessary to charge additionally if the piping
length 30 m.
INFORMATION
After opening the stop valve, it is possible that the pressure
in the refrigerant piping does not rise. This might be
caused by e.g. the closed state of the expansion valve in
the outdoor unit circuit, but does not present any problem
for correct operation of the unit.

13. Pump down operation
This unit is equipped with an automatic pump down operation which
will collect all refrigerant from the field piping and indoor unit in the
outdoor unit. To protect the environment, make sure to perform the
following pump down operation when relocating or disposing of the
unit.
When in need of operation, turn off the main power supply and
turn it on again. Make sure that stop valves both on liquid and
gas side are open and be sure to operate the unit in cooling
operation during test run.
NOTICE
Piping length is the one way length of liquid piping.
Connected piping length is between
Model 30~40 m 40~50 m
AZQS100~140 0.5 1.0
INFORMATION
For details about the combination of your outdoor and
indoor unit, see the engineering databook.
NOTICE
Before recharging, make sure to execute vacuum drying of
the internal piping of the unit as well. To do so, use the
internal service port of the unit. Do NOT use the service
ports located on the stop valve (see "9.3. Stop valve
operation" on page 8), since vacuum drying can not be
performed properly from these ports.
Outdoor units have 1 port on the piping. It is between the
heat exchanger and the 4-way valve.
WARNING
Some sections of the refrigerant circuit may be isolated
from other sections caused by components with specific
functions (e.g. valves). The refrigerant circuit therefore
features additional service ports for vacuuming, pressure
relief or pressurizing the circuit.
In case it is required to perform brazing on the unit, ensure
that there is no pressure remaining inside the unit. Internal
pressures need to be released with ALL the service ports
indicated on the figures below opened. The location is
depending on mode type.

14. Electrical wiring work
14.1. Precautions on electrical wiring work
Use only copper wires.
A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the fixed
wiring in accordance with applicable legislation.
Do not turn on the main switch until all the wiring is completed.
For Y1
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller of the indoor
unit indicates "U1" and the equipment cannot operate. Change
any two of the three power supply cables (L1, L2, L3) to correct
phase.
If the contact in the magnetic switch should be forcibly turned on
while the equipment is inoperative, the compressor will burn out.
Never try to forcibly turn on the contact.
Never squeeze bundled cables into a unit.
Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).
Secure the electrical wiring with cable ties as shown in the figure
in chapter "14.2. Connecting power supply and inter-unit wiring"
on page 13 so that it does not come in contact with the piping,
particularly on the high-pressure side.
Make sure no external pressure is applied to the terminal
connectors.
When installing the earth leakage circuit breaker make sure that
it is compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the earth
leakage circuit breaker.
As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.
14.2. Connecting power supply and inter-unit wiring
Secure the earth wire to the stop valve attachment plate so that
it does not slide.
Secure the earth wire to the stop valve attachment plate one
more time along with the electric wiring and the inter-unit wiring.
Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knock-out hole from
cutting the wires.
Follow the electric wiring diagram for electrical wiring works.
Form the wires and fix the cover firmly so that the cover may be
fit in properly.
14.3. Precautions on wiring of power supply and inter-
unit wiring
Use a round crimp-style terminal for connection to the power
supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following
instruction.
- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the below figure.
Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
Over-tightening the terminal screws can damage the screws.
See the table below for tightening torques for the terminal
screws.
WARNING
All wiring must be performed by an authorized
electrician.
All components procured on the site and all electric
construction shall comply with the applicable
legislation.
DANGER: HIGH VOLTAGE
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure the
voltage at the terminals of main circuit capacitors or
electrical parts and, before touching, make sure that those
voltages are 50 V DC or less.
NOTICE
To persons in charge of electrical wiring work:
Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
DANGER
Before obtaining access to terminal devices, all supply
circuits must be interrupted.
Be sure to install an earth leakage circuit breaker in
accordance with applicable legislation. Failure to do
so may cause electrical shock.
CAUTION
Be sure to install the required fuses or circuit breakers.

15.2. Test run
1Be sure to turn power on at least 6 hours before starting
operation in order to protect the compressor.
2Make sure the liquid and gas stop valves are open.
3Be sure to close the frontside panel before operation, as not
doing so can cause electric shock.
4Be sure to set the unit to cooling operation mode.
5Turn the unit on by means of the remote controller.
The test run will start automatically from the first moment the unit
receives the “ON” signal from the remote controller.
6During the test run the H2P TEST LED will be ON.
7When the H2P TEST LED is OFF, it marks the finishing of the
test run.
15.3. Precautions regarding test-runs
1In order to detect stop valves failing to open, operation of the
unit is compulsorily performed in cooling for 2-3 minutes during
the first test run, even if the remote controller was set to heating
operation. In this case, the remote controller will have kept
displaying the heating symbol all the time and the unit will switch
to heating operation automatically after elapse of that time.
2In case you cannot operate the unit in test run mode for any
unusual reason, refer to "15.4. Failure diagnosis at the moment
of first installation" on page 15.
3In case of a wireless remote controller, execute the test run only
after having installed the indoor unit decoration panel with infra-
red receiver first.
4In case the panels of indoor units are not yet installed to the
indoor units, make sure to shut off the power supply after
finishing the complete test run.
5A complete test run surely includes shutting off power after
having performed a normal operation stop on the remote
controller. Do not stop operation by turning circuit breakers off.
15.4. Failure diagnosis at the moment of first
installation
If the malfunction code "UA" is displayed on the remote
controller, there is a possibility that connection is with
incompatible indoor unit.
In case nothing is displayed on the remote controller (the
currently set temperature does not display), check for any of the
following abnormalities before you can diagnose possible
malfunction codes.
Disconnection or wiring error (between power supply and
outdoor unit, between outdoor unit and indoor units, between
indoor unit and remote controller).
The fuse on the outdoor unit PCB may have run out.
If the malfunction code "E3", "E4", "L8" or "U0" is displayed on the
remote controller, there is a possibility that the stop valves are
closed.
If the malfunction code "E3", "E4", "L4" or "L8" is displayed on the
remote controller, there is a possibility that air inlet or air outlet
are blocked.
If the malfunction code "U2" is displayed on the remote
controller, check for voltage imbalance.
If the malfunction code "U4" or "UF" is displayed on the remote
controller, check the inter-unit branch wiring connection.
The reversed phase protection detector of this product only
works during the initialisation stage after a power reset.
The reversed phase protection detector is designed to stop the
product in case of an abnormality when the product is started
up.
When the reversed phase protection circuit forced the unit to
stop, check if all phases are existing. If this is the case, shut
off the power supply to the unit and replace two of three
phases. Turn on power again and start the unit.
Reversed phase detection is not performed while the product
is operating.
In case of possible reversal of phases after a momentary
black out of power and the power goes on and off while the
product is operating, install a reversed phase protection
circuit on site. Such situation is not unimaginable when using
generators. Running the product in reversed phase can
break the compressor and other parts.
For a missing phase in case of Y1 units, "E7" or "U2" will be
displayed on the remote controller of the indoor unit.
Operation will be impossible with either one of these
phenomena. If this happens, turn off the power, re-check the
wiring and switch the position of two of the three electrical wires.
(If operation is not possible, do not under any circumstances
force the electromagnetic contactor on.)
CAUTION
Do NOT interrupt the test run!
