1.4. Before installation (relocation) -

electrical work

Caution:

Ground the unit.

- Do not connect the ground wire to gas or water pipes, lightning rods, or
telephone ground lines. Improper grounding may result in electric shock.

Never connect in reverse phases.
Never connect the Power Line L1, L2, and L3 to Terminal N.

- If the unit is miss wired, when power is supplied, some electrical parts will
be damaged.

Install the power cable so that tension is not applied to the cable.

- Tension may cause the cable to break and generate heat and cause a fi re.

Install a leak circuit breaker, as required.

- If a leak circuit breaker is not installed, electric shock may result.

Use power line cables of suffi cient current carrying capacity and rating.

- Cables that are too small may leak, generate heat, and cause a fi re.

Use only a circuit breaker and fuse of the specifi ed capacity.

- A fuse or circuit breaker of a larger capacity, or the use of a substitute
simple steel or copper wire may result in a general unit failure or fi re.

Do not wash the air conditioner units.

- Washing them may cause an electric shock.

Be careful that the installation base is not damaged by long use.

- If the damage is left uncorrected, the unit may fall and cause personal
injury or property damage.

Install the drain piping according to this Installation Manual to ensure
proper drainage. Wrap thermal insulation around the pipes to prevent
condensation.

- Improper drain piping may cause water leakage and damage to furniture
and other possessions.

Be very careful about transporting the product.

- One person should not carry the product. Its weight is in excess of 20kg.

- Some products use PP bands for packaging. Do not use any PP bands as
a means of transportation. It is dangerous.

- Do not touch the heat exchanger fi ns. Doing so may cut your fi ngers.

- When transporting the outdoor unit, support it at the specifi ed positions on
the unit base. Also support the outdoor unit at four points so that it cannot
slip sideways.

Safely dispose of the packing materials.

- Packing materials, such as nails and other metal or wooden parts, may
cause stabs or other injuries.

- Tear apart and throw away plastic packaging bags so that children will not
play with them. If children play with a plastic bag which has not been torn
apart, they face the risk of suffocation.

1.5. Before starting the test run

Caution:

Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch
can result in irreversible damage to internal parts. Keep the power switch
turned on during the operational season. Make sure of the phase order of
power supply and voltage between each phase.

Do not touch the switches with wet fi ngers.

- Touching a switch with wet fi ngers can result in an electric shock.

Do not touch the refrigerant pipes during and immediately after
operation.

- During and immediately after operation, the refrigerant pipes may be hot
or cold, depending on the condition of the refrigerant fl owing through the
refrigerant piping, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrigerant pipes.

Do not operate the air conditioner with the panels and guards removed.

- Rotating, hot, or high-voltage parts can cause injuries.

Do not turn off the power immediately after stopping operation.

- Always wait at least 5 minutes before turning off the power. Otherwise,
drainage water leakage or mechanical failure of sensitive parts may occur.

1.2. Precautions for devices that use
R410A refrigerant

Caution:

Do not use existing refrigerant piping.

- The old refrigerant and refrigerant oil in the existing piping contains a large
amount of chlorine which may cause the refrigerant oil of the new unit to
deteriorate.

- R410A is a high-pressure refrigerant and can cause the existing piping to
burst.

Use refrigerant piping made of phosphorus deoxidized copper and
copper alloy seamless pipes and tubes. In addition, be sure that the
inner and outer surfaces of the pipes are clean and free of hazardous
sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other
contaminant.

- Contaminants on the inside of the refrigerant piping may cause the
refrigerant oil to deteriorate.

Store the piping to be used during installation indoors and keep both
ends of the piping sealed until just before brazing. (Store elbows and
other joints in a plastic bag.)

- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and
compressor failure may result.

Apply a small amount of ester oil, ether oil, or alkyl benzene to fl ares.
(for indoor unit)

- Infi ltration of a large amount of mineral oil may cause the refrigerant oil to
deteriorate.

Use liquid refrigerant to fi ll the system.

- If gas refrigerant is used to fi ll the system, the composition of the
refrigerant in the cylinder will change and performance may drop.

Do not use a refrigerant other than R410A.

- If another refrigerant (R22, etc.) is mixed with R410A, the chlorine in the
refrigerant may cause the refrigerant oil to deteriorate.

Use a vacuum pump with a reverse fl ow check valve.

- The vacuum pump oil may fl ow back into the refrigerant cycle and cause
the refrigerant oil to deteriorate.

Do not use the following tools that are used with conventional
refrigerants.
(Gauge manifold, charge hose, gas leak detector, reverse fl ow check
valve, refrigerant charge base, refrigerant recovery equipment)

- If the conventional refrigerant and refrigerant oil are mixed in the R410A,
the refrigerant may deteriorate.

- If water is mixed in the R410A, the refrigerant oil may deteriorate.

- Since R410A does not contain any chlorine, gas leak detectors for
conventional refrigerants will not react to it.

Do not use a charging cylinder.

- Using a charging cylinder may cause the refrigerant to deteriorate.

Be especially careful when managing the tools.

- If dust, dirt, or water gets into the refrigerant cycle, the refrigerant may
deteriorate.

1.3. Before installation

Caution:

Do not install the unit where combustible gas may leak.

- If the gas leaks and accumulates around the unit, an explosion may result.

Do not use the air conditioner where food, pets, plants, precision
instruments, or artwork are kept.

- The quality of the food, etc. may deteriorate.

Do not use the air conditioner in special environments.

- Oil, steam, sulfuric smoke, etc. can signifi cantly reduce the performance of
the air conditioner or damage its parts.

When installing the unit in a hospital, communication station, or similar
place, provide suffi cient protection against noise.

- Inverter equipment, private power generator, high-frequency medical
equipment, or radio communication equipment may cause the air
conditioner to operate erroneously, or fail to operate. On the other hand,
the air conditioner may affect such equipment by creating noise that
disturbs medical treatment or image broadcasting.

Do not install the unit on or over things that are subject to water
damage.

- When the room humidity exceeds 80% or when the drain pipe is clogged,
condensation may drip from the indoor unit. Perform collective drainage
work together with the outdoor unit, as required.

2. About the product

This unit uses R410A-type refrigerant.
Piping for systems using R410A may be different from that for systems using

conventional refrigerant because the design pressure in systems using
R410A is higher. Refer to the Data Book for more information.

Some of the tools and equipment used for installation with systems that use
other types of refrigerant cannot be used with the systems using R410A.
Refer to the Data Book for more information.

•

•

•

Do not use the existing piping, as it contains chlorine, which is found in
conventional refrigerating machine oil and refrigerant. This chlorine will
deteriorate the refrigerant machine oil in the new equipment. The existing
piping must not be used as the design pressure in systems using R410A
is higher than that in the systems using other types of refrigerant and the
existing pipes may burst.

Caution:

Do not vent R410A into the atmosphere.
R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol
with a Global Warming Potential (GWP) = 1975.

8. Installation of unit

9. Refrigerant piping installation

The pipe is connected via a terminal-branch type connection in which refrigerant
piping from the outdoor unit is branched at the terminal and is connected to each
of the indoor units.
The method of pipe connection is as follows: fl are connection for the indoor
units, low-pressure pipes and high-pressure pipes for outdoor units, brazed
connection. Note that the branched sections are brazed.

Warning:

Always use extreme care to prevent the refrigerant gas from leaking while
using fi re or fl ame. If the refrigerant gas comes in to contact with a fl ame
from any source, such as a gas stove, it breaks down and generates
a poisonous gas which can cause gas poisoning. Never weld in an
unventilated room. Always conduct an inspection for gas leakage after
installation of the refrigerant piping has been completed.

Caution:

Do not vent R410A into the atmosphere.
R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol
with a Global Warming Potential (GWP) = 1975.

9.1. Caution

This unit uses refrigerant R410A. Follow the local regulations on materials and
pipe thickness when selecting pipes. (Refer to the table below.)

1 Use the following materials for refrigeration piping.

Material: Use copper alloy seamless pipes made of phosphorus
deoxidized copper. Ensure the inner and outer surfaces of the pipes
are clean and free from hazardous sulfur, oxide, dusts, shaving
particles, oils, and moisture (contamination).
Size: Refer to item 9.2. for detailed information on refrigerant piping
system.

2 Commercially available piping often contains dust and other materials.

Always blow it clean with a dry inert gas.

3 Use care to prevent dust, water or other contaminants from entering the

piping during installation.

6 Use a fi tting if a specifi ed refrigerant pipe has a different diameter from that

of a branching pipe.

7 Always observe the restrictions on the refrigerant piping (such as rated

length, height difference, and piping diameter) to prevent equipment failure
or a decline in heating/cooling performance.

8 Either a lack or an excess of refrigerant causes the unit to make an

emergency stop. Charge the system with an appropriate amount of
refrigerant. When servicing, always check the notes concerning pipe
length and amount of additional refrigerant at both locations, the refrigerant
volume calculation table on the back of the service panel and the additional
refrigerant section on the labels for the combined number of indoor units
(Refer to item 9.2. for detailed information on refrigerant piping system).

9 Be sure to charge the system using liquid refrigerant.
0 Never use refrigerant to perform an air purge. Always evacuate using a

vacuum pump.

a Always insulate the piping properly. Insuffi cient insulation will result in a

decline in heating/cooling performance, water drops from condensation and
other such problems (Refer to item 10.4 for thermal insulation of refrigerant
piping).

b When connecting the refrigerant piping, make sure the valve of the outdoor

unit is completely closed (the factory setting) and do not operate it until
the refrigerant piping for the outdoor, indoor units and BC controller has
been connected, a refrigerant leakage test has been performed and the
evacuation process has been completed.

c Braze only with non-oxide brazing material for piping. Failure to do so

may damage the compressor. Be sure to perform the non-oxidation
brazing with a nitrogen purge.

Do not use any commercially available anti-oxidizing agent since it may

cause pipe corrosion and degrading of the refrigerant oil.
Please contact Mitsubishi Electric for more details.
(Refer to item 10.2. for details of the piping connection and valve operation)

d Never perform outdoor unit piping connection work when it is raining.

Warning:

When installing and moving the unit, do not charge the system with any
other refrigerant other than the refrigerant specifi ed on the unit.

- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to

malfunction and may result in severe damage.

Caution:

Use a vacuum pump with a reverse fl ow check valve.

- If the vacuum pump does not have a reverse fl ow check valve, the vacuum
pump oil may fl ow back into the refrigerant cycle and cause deterioration of
the refrigerant oil.

Do not use the tools shown below used with conventional refrigerant.
(Gauge manifold, charge hose, gas leak detector, check valve,
refrigerant charge base, vacuum gauge, refrigerant recovery
equipment)

- Mixing of conventional refrigerant and refrigerant oil may cause the
refrigerant oil to deteriorate.

- Mixing of water will cause the refrigerant oil to deteriorate.

- R410A refrigerant does not contain any chlorine. Therefore, gas leak
detectors for conventional refrigerants will not react to it.

Manage the tools used for R410A more carefully than normal.

- If dust, dirt, or water gets in the refrigerant cycle, the refrigerant oil will
deteriorate.

Never use existing refrigerant piping.

- The large amount of chlorine in conventional refrigerant and refrigerant oil
in the existing piping will cause the new refrigerant to deteriorate.

Store the piping to be used during installation indoors and keep both
ends of the piping sealed until just before brazing.

- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate
and the compressor may fail.

Do not use a charging cylinder.

- Using a charging cylinder may cause the refrigerant to deteriorate.

Do not use special detergents for washing piping.

10. Additional refrigerant charge

At the time of shipping, the outdoor unit is charged with refrigerant.
This charge does not include the amount needed for extended piping and
additional charging of each refrigerant line will be required on site. In order that
future servicing may be properly provided, always keep a record of the size and
length of each refrigerant line and the amount of additional charge by writing it in
the space provided on the outdoor unit.

10.1. Calculation of additional refrigerant
charge

Calculate the amount of additional charge based on the length of the piping
extension and the size of the refrigerant line.

Use the table below as a guide for calculating the amount of additional
charging and then charge the system accordingly.

If the calculation results in a fraction of less than 0.1 kg, round up to the next

0.1 kg. For example, if the result of the calculation was 30.73 kg, round the
result up to 30.8 kg.

10.2. Precautions concerning piping
connection and valve operation

Conduct piping connection and valve operation accurately and carefully.

Removing the pinched connecting pipe

When shipped, a pinched connecting pipe is attached to the on site high­pressure and low-pressure valves to prevent gas leakage.
Take the following steps 1 through 4 to remove the pinched connecting
pipe before connecting refrigerant pipes to the outdoor unit.

1 Check that the refrigerant service valve is fully closed (turned clockwise

all the way).

2 Connect a charging hose to the service port on the low-pressure/

high-pressure refrigerant service valve, and extract the gas in the
pipe section between the refrigerant service valve and the pinched
connecting pipe.

3 After vacuuming gas from the pinched connecting pipe, sever the

pinched connecting pipe at the location shown in [Fig.10.2.1] and drain
the refrigerant.

4 After completing 2 and 3 heat the brazed section to remove the

pinched connecting pipe.

Warning:

The sections between the refrigerant service valves and the pinched
connecting pipes are fi lled with gas and refrigerant oil. Extract the gas
and refrigerant oil in the above-mentioned pipe section before heating
the brazed section to remove the refrigerant service valve pinched
connecting pipe.

- If the brazed section is heated without fi rst extracting the gas and
refrigerant oil, the pipe may burst or the pinched connecting pipe may blow
off and ignite the refrigerant oil, causing serious injury.

Caution:

Place a wet towel on the refrigerant service valve before heating the brazed
section to keep the temperature of the valve from exceeding 120 ˚C.
Direct the fl ame away from the wiring and metal sheets inside the unit
to prevent heat damage.

Caution:

Do not vent R410A into the atmosphere.
R410A is a Fluorinated Greenhouse gas, covered by the Kyoto
Protocol, with a Global Warming Potential (GWP) = 1975.

open. If operating with the valve closed, abnormal pressure will be imparted
to the high- or low-pressure side of the refrigerant circuit, giving damage to
the compressor, four-way valve, etc.

Determine the amount of additional refrigerant charge by using the formula,
and charge refrigerant additionally through the service port after completing
piping connection work.

After completing work, tighten the service port and cap securely so as not to
generate any gas leakage. (Refer to the table on the below for appropriate
tightening torque.)

Caution:

Keep the valve closed until refrigerant charging to the pipes to be
added on site has been completed. Opening the valve before charging
the refrigerant may cause damage to the unit.
Do not use a leak detection additive.

Make sure to seal-off the space around areas where the wires and refrigerant
pipes enter the unit to ensure that small animals, rainwater, or snow cannot
enter the unit through such openings and cause damage to the unit.

Caution:

Make sure to seal-off the openings for the pipe and wire retrieval.

Small animals, rainwater, or snow entering through the openings may
cause damage to the device.

10.3. Airtight test, evacuation, and
refrigerant charging

1 Airtight test
Perform with the valve of the outdoor unit closed, and pressurize the

connection piping and the indoor unit from the service port provided on the
valve of the outdoor unit. (Always pressurize from both the high-pressure
pipe and the low-pressure pipe service ports.)

Observe the following restrictions when conducting an air tightness test
to prevent negative effects on the refrigerating machine oil. Also, with
nonazeotropic refrigerant (R410A), gas leakage causes the composition to
change and affects performance. Therefore, perform the airtightness test
cautiously.

•

Caution:

Only use refrigerant R410A.

- The use of other refrigerants such as R22 or R407C, which contains chlorine,
will deteriorate the refrigerating machine oil or cause the compressor to
malfunction.

2 Evacuation
Evacuate with the valve of the outdoor unit closed and evacuate both the

connection piping and the indoor unit from the service port provided on the
valve of the outdoor unit using a vacuum pump. (Always evacuate from the
service port of both the high-pressure pipe and the low-pressure pipe.) After
the vacuum reaches 650 Pa [abs], continue evacuation for at least one hour
or more. Then, stop the vacuum pump and leave it for 1 hour. Ensure the
degree of vacuum has not increased. (If the degree of vacuum increase

is larger than 130 Pa, water might have entered. Apply pressure to dry
nitrogen gas up to 0.05 MPa and vacuum again.) Finally, seal in with the

liquid refrigerant through the high-pressure pipe, and adjust the low-pressure
piping to obtain an appropriate amount of the refrigerant during operation.

* Never perform air purging using refrigerant.

Note:

Always add an appropriate amount of refrigerant. Also always charge
the system with liquid refrigerant.
Use a gauge manifold, charging hose, and other parts for the
refrigerant indicated on the unit.
Use a graviometer. (One that can measure down to 0.1 kg.)
Use a vacuum pump with a reverse fl ow check valve.
(Recommended vacuum gauge: ROBINAIR 14830A Thermistor Vacuum
Gauge)
Also use a vacuum gauge that reaches 65 Pa [abs] or below after
operating for fi ve minutes.

3 Refrigerant Charging
Since the refrigerant used with the unit is nonazerotropic, it must be charged

in the liquid state. Consequently, when charging the unit with refrigerant from
a cylinder, if the cylinder does not have a syphon pipe, charge the liquid
refrigerant by turning the cylinder upside-down as shown in Fig.10.3.3. If
the cylinder has a syphon pipe like that shown in the picture on the right,
the liquid refrigerant can be charged with the cylinder standing upright.
Therefore, give careful attention to the cylinder specifi cations. If the unit
should be charged with gas refrigerant, replace all the refrigerant with new
refrigerant. Do not use the refrigerant remaining in the cylinder.

Airtight test procedure Restriction

(1) After pressurizing to the design pressure (4.15 MPa) using nitrogen gas, allow it to

stand for about one day. If the pressure does not drop, airtightness is good.
However, if the pressure drops, since the leaking point is unknown, the following
bubble test may also be performed.

(2) After the pressurization described above, spray the fl are connection parts, brazed

parts, and other parts that may leak with a bubbling agent (Gupofl ex, etc.) and visually
check for bubbles.

(3) After the airtight test, wipe off the bubbling agent.

If a fl ammable gas or air (oxygen) is used as the pressurization
gas, it may catch fi re or explode.

GB

11.1. Caution

1 Follow ordinance of your governmental organization for technical standard

related to electrical equipment, wiring regulations and guidance of each
electric power company.

2 Wiring for control (hereinafter referred to as transmission line) shall be (5

cm or more) apart from power source wiring so that it is not infl uenced by
electric noise from power source wiring (Do not insert transmission line and
power source wire in the same conduit).

3 Be sure to provide designated grounding work to the outdoor unit.
4 Give some allowance to wiring for the electrical control box on the indoor

and outdoor units, because these boxes are sometimes removed at the time
of service work.

5 Never connect the main power source to the terminal block of the

transmission line. If connected, electrical parts will burn out.

6 Use 2-core shield cable for the transmission line. If transmission lines of

different systems are wired with the same multiplecore cable, the resultant
poor transmitting and receiving will cause erroneous operations.

7 Only the transmission line specifi ed should be connected to the terminal

block for outdoor unit transmission.

Erroneous connection does not allow the system to operate.
8 In the case of connecting with an upper class controller or to conduct group

operation in different refrigerant systems, the control line for transmission is
required between the outdoor units in different refrigerant systems.

Connect this control line between the terminal blocks for centralized control

(2-wire line with no polarity).

9 Grouping is set by operating the remote controller.

11.2. Control box and connecting position

of wiring

1 Outdoor unit

1. Remove the front panel of the control box by removing the 4 screws and

pushing it up a little before pulling it out.

2. Connect the indoor - outdoor transmission line to the terminal block (TB3) for

the indoor - outdoor transmission line.

If multiple outdoor units are connected in the same refrigerant system, daisy-

chain TB3 (M1, M2,

Terminal) on the outdoor units. Connect the indoor -

outdoor transmission line for the outdoor units to TB3 (M1, M2,

Terminal)

of only one of the outdoor units.

3. Connect the transmission lines for centralized control (between the
centralized control system and the outdoor unit of different refrigerant
systems) to the terminal block for centralized control (TB7). If the multiple
outdoor units are connected to the same refrigerant system, daisy-chain TB7
(M1, M2, S Terminal) on the outdoor units in the same refrigerant system.
(*1)
*1: If TB7 on the outdoor unit in the same refrigerant system is not daisy-

chained, connect the transmission line for centralized control to TB7 on
the OC (*2). If the OC is out of order, or if the centralized control is being
conducted during the power supply shut-off, daisy-chain TB7 on the OC
and OS (In the case that the outdoor unit whose power supply connector
CN41 on the control board has been replaced with CN40 is out of order
or the power is shut-off, centralized control will not be conducted even
when TB7 is daisy-chained).

*2: OC and OS of the outdoor units in the same refrigerant system are

automatically identifi ed. They are identifi ed as OC and OS in descending
order of capacity (If the capacity is the same, they will be in ascending
order of their address number).

4. In the case of indoor-outdoor transmission line, connect the shield ground to
the grounding terminal (

). In the case of transmission lines for centralized
control, connect it to the shield terminal (S) on the terminal block for
centralized control (TB7). Furthermore, in the case of the outdoor units
whose power supply connector CN41 is replaced with CN40, short circuit the
shield terminal (S) and the grounding terminal (

) in addition to the above.

5. Fix the connected wires securely in place with the cable strap at the bottom
of the terminal block. External force applied to the terminal block may
damage it resulting in a short circuit, ground fault, or a fi re.

2 Conduit tube installation

Open by hammering the knockout holes for the conduit tube located on the
base and the bottom part of the front panel.

When installing the conduit tube directly through the knockout holes, remove
the burr and protect the tube with masking tape.

Use the conduit tube to narrow down the opening if there is a possibility of
small animals entering the unit.

When taking the conduit tube out from the bottom part of the unit, caulk
around the tube opening to prevent water penetration.

Pipe size 28.58 mm to 38.1 mm 15 mm or more

* Installation of pipes in a high-temperature high-humidity environment, such

as the top fl oor of a building, may require the use of insulation materials
thicker than the ones specifi ed in the chart above.

* When certain specifi cations presented by the client must be met, ensure that

they also meet the specifi cations on the chart above.

•

10.4. Thermal insulation of refrigerant
piping

Be sure to add insulation work to refrigerant piping by covering high-pressure
pipe and low-pressure pipe separately with enough thickness heat-resistant
polyethylene, so that no gap is observed in the joint between indoor unit and
insulating material, and insulating materials themselves. When insulation work is
insuffi cient, there is a possibility of condensation drip, etc. Pay special attention
to insulation work in the ceiling plenum.

Verwenden Sie keine bereits vorhandenen Kältemittelleitungen.

- In den vorhandenen Leitungen verbliebenes altes Kältemittelöl kann einen
hohen Chloranteil aufweisen und einen Güteverlust des Kältemittelöls des
neuen Geräts verursachen.

- R410A ist ein Hochdruckkältemittel, das im Bersten der vorhandenen
Leitungen resultieren kann.

Verwenden Sie Kältemittelleitungen aus deoxidiertem Phosphorkupfer
sowie nahtlose Kupferlegierungsleitungen und -rohre. Vergewissern Sie
sich des Weiteren, dass die Innen- und Außenfl ächen der Leitungen frei
von gefährlichen Rückständen wie Schwefel, Oxiden, Staub/Schmutz,
Spänen, Ölen, Feuchtigkeit und jeglichen anderen Kontaminierungen sind

- Kontaminierungsstoffe im Inneren der Kältemittelleitungen können einen
Güteverlust des Kältemittelöls bewirken.

Lagern Sie die bei der Installation zu verwendenden Rohrleitungen
in einem Innenraum und halten Sie beide Rohrenden bis kurz vor
dem Hartlöten verschlossen. (Bewahren Sie Rohrbögen und andere
Verbindungselemente in einem Kunststoffbeutel auf.)

-

Das Eindringen von Staub, Schmutz oder Wasser in den Kältemittelkreislauf
kann im Güteverlust des Öls und im Ausfall des Kompressors resultieren.

Tragen Sie etwas Esteröl, Ätheröl oder Alkylbenzol auf die Rohrmuffen
auf. (Innengerät)

- Das Eindringen einer größeren Menge von Mineralöl kann einen
Güteverlust des Kältemittelöls verursachen.

Verwenden Sie fl üssiges Kältemittel zum Füllen des Systems.

-

Wenn das System mit Kältegas gefüllt wird, ändert sich die Zusammensetzung
des Kältemittels im Zylinder und es kann zu einem Leistungsverlust kommen.

Verwenden Sie kein anderes Kältemittel als R410A.

-

Falls ein anderes Kältemittel (R22 usw.) mit R410A gemischt wird, kann das im
Kältemittel enthaltene Chlor einen Güteverlust des Kältemittelöls verursachen.

Verwenden Sie eine Vakuumpumpe mit Rückschlagventil.

- Aus der Vakuumpumpe könnte Öl in den Kältemittelkreislauf zurückfl ießen
und einen Güteverlust des Kältemittelöls verursachen.

Verwenden Sie keine der folgenden Hilfsmittel, die in Verbindung mit
herkömmlichen Kältemitteln verwendet werden.
(Messverteiler, Füllschlauch, Gasleckagedetektor, Rückschlagventil,
Kältemittelfüllständer, Kältemittelrückgewinnungsausrüstung)

- Das Mischen von herkömmlichem Kältemittel mit Kältemittelöl kann einen
Güteverlust des R410A-Kältemittels verursachen.

- Das Mischen von Wasser und R410A kann einen Güteverlust des
Kältemittelöls verursachen.

- Da R410A vollkommen chlorfrei ist, sprechen für herkömmliche Kältemittel
verwendete Gasleckagesensoren unter Umständen nicht an.

Verwenden Sie keinen Füllzylinder.

- Die Verwendung eines Füllzylinders kann einen Güteverlust des
Kältemittels verursachen.

Gehen Sie bei der Handhabung der Hilfsmittel besonders sorgfältig vor.

- Falls Staub, Schmutz oder Wasser in den Kältemittelkreislauf eindringt,
kann dies einen Güteverlust des Kältemittels verursachen.

1.3. Vor der Installation

Vorsicht:

Installieren Sie das Gerät nicht an Orten, wo brennbares Gas austreten kann.

-

Wenn Gas austritt und sich um das Gerät ansammelt, besteht Explosionsgefahr.

Verwenden Sie das Klimagerät nicht in der Nähe von
Lebensmitteln, Haustieren, Pfl anzen, Präzisionsinstrumenten oder
Kunstgegenständen.

-

Andernfalls könnte die Qualität der Lebensmittel usw. beeinträchtigt werden.

Verwenden Sie das Klimagerät nicht in Sonderumgebungen.

- Öl, Dampf, schwefelhaltiger Rauch usw. können eine signifi kante
Leistungsminderung des Klimageräts oder eine Beschädigung seiner Teile
verursachen.

Bei der Installation des Geräts in einem Krankenhaus, einer
Kommunikationszentrale oder ähnlichen Orten ist für eine
ausreichende Schalldämmung zu sorgen.

- Wechselrichter, private Stromgeneratoren, medizinische
Hochfrequenzgeräte oder Funkanlagen können den Betrieb des
Klimageräts beeinträchtigen oder seinen Ausfall verursachen.
Demgegenüber kann sich das Klimagerät selbst durch Störgeräusche auf
solche Geräte oder Anlagen auswirken und zum Beispiel die medizinische
Behandlung oder Bildübertragung stören.

Installieren Sie das Gerät nicht an oder über Gegenständen, die anfällig
gegen Wasserschäden sind.

-

Bei einer Raumfeuchtigkeit von mehr als 80% oder einer blockierten
Drainageleitung kann Kondensat aus dem Innengerät auslaufen. Treffen Sie

2. Produktinformationen

Dieses Gerät verwendet Kältemittel des Typs R410A.
Rohrleitungen für Systeme, die R410A verwenden, können aufgrund des

konstruktionsbedingten höheren Drucks bei Verwendung von R410A von
denen für Systeme, die herkömmliche Kältemittel verwenden, abweichen.
Weitere Informationen sind im Datenbuch enthalten.

Einige zur Installation von Systemen, die andere Kältemitteltypen einsetzen,
verwendete Hilfsmittel und Geräte können nicht für Systeme verwendet
werden, die R410A einsetzen. Weitere Informationen sind im Datenbuch
enthalten.

•

•

•

Verwenden Sie keine vorhandenen Rohrleitungen, da diese Chlor enthalten,
das in herkömmlichen Kühlmaschinenölen und Kältemitteln Verwendung
fi ndet. Das Chlor beeinträchtigt das im neuen System verwendete
Kältemittelöl. Die vorhandenen Rohrleitungen dürfen auch deshalb nicht
verwendet werden, weil der konstruktionsbedingte Druck in Systemen,
die R410A verwenden, höher ist als in Systemen, die andere Kältemittel
verwenden, so dass die vorhandenen Rohrleitungen bersten könnten.

Vorsicht:

Lassen Sie R410A nicht in die Atmosphäre ab.
R410A ist ein vom Kyoto-Protokoll erfasstes fl uorhaltiges Treibhausgas
mit einem GWP (Global Warming Potential) von 1975.

9. Installieren der Kältemittelleitungen

Die Leitung wird an einen Verteiler angeschlossen, an dem die vom Außengerät
kommende Leitung zu jedem der Innengeräte verzweigt wird.
Die Rohranschlüsse werden wie folgt hergestellt: Bördelverbindung für die
Innengeräte, Niederdruck- und Hochdruckrohrleitungen, hartgelötete Verbindung
für die Außengeräte. Beachten Sie, dass die abgezweigten Abschnitte
hartgelötet sind.

Achtung:

Gehen Sie bei der Verwendung von Feuer und Flammen stets extrem
sorgfältig vor, um das Austreten des Kältegases zu verhindern. Wenn das
Kältegas mit einer Flamme in Kontakt kommt, wie zum Beispiel einem
Gasherd, zersetzt es sich und setzt Giftgas frei, das zu einer Gasvergiftung
führen kann. Führen Sie Schweißarbeiten nie in unbelüfteten Räumen
durch. Führen Sie nach dem Installieren der Kältemittelrohrleitungen stets
eine Gasleckageinspektion durch.

Vorsicht:

Lassen Sie R410A nicht in die Atmosphäre ab.
R410A ist ein vom Kyoto-Protokoll erfasstes fl uorhaltiges Treibhausgas
mit einem GWP (Global Warming Potential) von 1975.

9.1. Vorsichtshinweise

Dieses Gerät verwendet Kältemittel des Typs R410A. Befolgen Sie bei der
Auswahl der Rohrleitungen die örtlich geltenden Vorschriften für Material und
Rohrstärke. (Siehe Tabelle, unten.)

1 Verwenden Sie für die Kältemittelrohrleitungen die folgenden Materialien:

Material: Verwenden Sie aus deoxidiertem Phosphorkupfer
gefertigte nahtlose Kupferlegierungsrohre. Stellen Sie sicher,
dass die Innen- und Außenfl ächen der Rohre sauber und frei von
gefährlichen Rückständen wie Schwefel, Oxid, Staub, Spänen, Öl
und Feuchtigkeit sind (Kontaminierung).
Größe: Abschnitt 9.2. enthält detaillierte Angaben zum
Kältemittelrohrleitungssystem.

2 Handelsübliche Rohre enthalten häufi g Staub oder anderes Material. Blasen

Sie sie stets mit einem trockenen Schutzgas sauber.

3 Achten Sie während der Installation sorgfältig darauf, dass kein Staub,

Wasser oder sonstige Verunreinigungen in die Rohre eindringen.

4 Begrenzen Sie die Anzahl der Biegungen soweit wie möglich und legen Sie

die Biegeradien möglichst groß aus.

5 Verwenden Sie für Abzweigungen und Sammler im Innen- und Außenbereich

stets die folgenden Zwillingsrohr- und Sammelrohrsätze (getrennt erhältlich).

* Für die Rohrgröße ø19,05 (3/4 Zoll) können an R410A-Klimageräten beide

Rohrtypen verwendet werden.

6 Verwenden Sie ein Fitting, falls eine angegebene Kältemittelleitung einen

anderen Durchmesser als eine Zweigleitung hat.

7 Beachten Sie stets die Grenzwerte für die Kältemittelleitung (wie zum

Beispiel die Nennlänge, den Höhenunterschied und den Rohrdurchmesser),
um einen Geräteausfall oder einen Heiz-/Kühlleistungsverlust zu verhindern.

•

•

•

•

8 Die Notausschaltung des Geräts spricht sowohl bei zuwenig als auch

zuviel Kältemittel an. Füllen Sie das System mit der angemessenen
Menge Kältemittel. Lesen Sie bei Wartungsarbeiten stets die Notizen
zur Rohrlänge und zur Kältemittelnachfüllmenge an beiden Stellen - der
Berechnungstabelle für die Kältemittelmenge an der Rückseite der
Wartungsabdeckung und den Abschnitt bezüglich der Kältemittelnachfüllung
auf den Etiketten für alle Innengeräte. (Abschnitt 9.2. enthält detaillierte
Angaben zum Kältemittelrohrleitungssystem.)

9 Füllen Sie das System nur mit fl üssigem Kältemittel.
0 Verwenden Sie Kältemittel nie zum Entlüften des Systems. Verwenden

Sie zum Entlüften stets eine Vakuumpumpe.

a Isolieren Sie die Rohrleitungen stets ordnungsgemäß. Eine unzureichende

Isolierung resultiert in einem Verlust der Heiz-/Kühlleistung, Wasserbildung
durch Kondensation und ähnlichen Problemen. (Die Thermoisolierung der
Kältemittelleitungen ist im Abschnitt 10.4 beschrieben.)

b

Vergewissern Sie sich beim Anschließen der Kältemittelleitungen, dass das
Ventil am Außengerät vollständig geschlossen ist (die werksseitige Einstellung)
und betätigen Sie es nicht, bis die Kältemittelleitungen für die Außengeräte,
Innengeräte und BC-Steuerung angeschlossen sind, ein Kältemittelleckagetest
durchgeführt wurde und die Systementlüftung abgeschlossen ist.

c Verwenden Sie zum Hartlöten nur oxidfreies Material für Rohrleitungen.

Andernfalls kann der Kompressor beschädigt werden. Führen Sie zum
Hartlöten unbedingt eine Stickstoffspülung durch.

Verwenden Sie keine im Handel erhältlichen antioxygenen Mittel,

da diese in der Korrosion der Rohre und einem Güteverlust des
Kältemittelöls resultieren können.
Bitte wenden Sie sich bezüglich weiterer Einzelheiten an Mitsubishi Electric.

(Abschnitt 10.2. enthält Details zum Rohrleitungsanschluss und zur

Verwendung des Ventils.)

d Führen Sie den Rohrleitungsanschluss für das Außengerät nie bei

Regen aus.

Achtung:

Füllen Sie das Gerät bei der Installation und beim Transport mit keinem
anderen als dem am Gerät angegebenen Kältemittel.

-

Das Beimischen von einem anderen Kältemittel, Luft usw. kann eine
Funktionsstörung des Kältemittelkreislaufs und schwere Schäden verursachen.

Vorsicht:

Verwenden Sie eine Vakuumpumpe mit Rückschlagventil.

- Wenn die Vakuumpumpe nicht mit einem Rückschlagventil ausgestattet ist,
könnte in der Pumpe befi ndliches Öl in den Kältemittelkreislauf gelangen
und einen Güteverlust des Kältemittelöls verursachen.

Verwenden Sie keine der folgenden Hilfsmittel, die in Verbindung mit
herkömmlichen Kältemitteln verwendet werden.
(Messverteiler, Füllschlauch, Gasleckagedetektor,
Rückschlagventil, Kältemittelfüllständer, Unterdruckmesser,
Kältemittelrückgewinnungsausrüstung)

- Das Mischen von herkömmlichem Kältemittel und Kältemittelöl kann einen
Güteverlust des Kältemittelöls verursachen.

-

Das Beimischen von Wasser verursacht einen Güteverlust des Kältemittelöls.

- R410A-Kältemittel ist vollkommen chlorfrei. Für herkömmliche Kältemittel
verwendete Gasleckagesensoren sprechen deshalb nicht an.

Behandeln Sie die für R410A verwendeten Hilfsmittel sorgfältiger als üblich.

- Falls Staub, Schmutz oder Wasser in den Kältemittelkreislauf eindringt,
kann dies einen Güteverlust des Kältemittelöls verursachen.

Verwenden Sie niemals bereits vorhandene Kältemittelrohre.

-

Der hohe Chlorgehalt von herkömmlichem Kältemittel und Kältemittelöl in bereits
vorhandenen Rohren verursacht einen Güteverlust des neuen Kältemittels.

Lagern Sie die bei der Installation zu verwendenden Rohre in einem
Innenraum und halten Sie beide Rohrenden bis kurz vor dem Hartlöten
verschlossen.

- Falls Staub, Schmutz oder Wasser in den Kältemittelkreislauf eindringt,
resultiert dies in einem Güteverlust des Kältemittels und einem möglichen
Ausfall des Kompressors.

Verwenden Sie keinen Füllzylinder.

- Die Verwendung eines Füllzylinders kann einen Güteverlust des
Kältemittels verursachen.

Verwenden Sie keine Spezialreiniger zum Reinigen der Rohrleitungen.
