HWE10140 GB
Precautions for handling units for use with R410A
CAUTION
Use refrigerant piping made of phosph orus deoxidized
copper and copper alloy seamle ss pipes an d tubes. In
addition, be sure that the inner and outer surfaces and
the end faces of the existing and new 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 or cause the air conditioning unit to malfunction.
Store the new 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.
Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flanges.
Infiltration of a large amount of mineral oil may cause the refrigerant oil to deteriorate or ca u s e th e a i r co nd i tioning unit
to malfunction.
Charge liquid refrigerant (as opposed to gaseous refrigerant) into the system.
If gaseous refrigerant is charged into the system, the composition of the refrigerant in the cylinder will change and
may result in performance loss.
Use a vacuum pump with a reverse-flow check valve.
If a vacuum pump that is not equipped with a reverse-flow
check valve is used, the vacuum pump oil may flow into the
refrigerant cycle and cause the refrigerating machine oil to
deteriorate.
Prepare tools for exclusive use with R410A. Do not use
the following tools if they have been used with the conventional refrigerant (gauge manifold, charging hose,
gas leak detector, reverse-flow check valve, refrigerant
charge base, vacuum gauge, and refrigerant recovery
equipment.).
If the refrigerant or the refrigerating machine oil left on
these tools are mixed in with R410A, it may cause the refrigerating machine oil to deteriorate.
Infiltration of water may cause the refrigerating machine
oil to deteriorate.
Gas leak detectors for conventional refrigerants will not
detect an R410A leak because R410A is free of chlorine.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of the refrigerant will change, and the unit may experience power loss.
Exercise special care when handling the tools for use
with R410A.
Infiltration of dust, dirt, or water into the refrigerant system
may cause the refrigerating machine oil to deteriorate.
iv
HWE10140 GB

1. Check the type of refrigerant used in the system to be serviced.
Refrigerant Type
Multi air conditioner for building application REPLACE MULTI YJM-B series R410A
2. Check the symptoms exhibited by the unit to be serviced.
Refer to this service handbook for symptoms relating to the refrigerant cycle.
3. Thoroughly read the safety precautions at the beginning of this manual.
4. Preparing necessary tools: Prepare a set of tools to be used exclusively with each type of refrigerant.
Refer to the manuals that came the tools for the correct usage.
5. Verification of the connecting pipes: Verify the type of refrigerant used for the unit to be moved or replaced.
Use refrigerant piping made of phosphorus deoxidized copper. Keep the inner and outer surfaces of the new pipes and the
end of the existing pipes clean and free of such contaminants as sulfur, oxides, dust, dirt, shaving particles, oil, and moisture.
These types of contaminants inside the refrigerant pipes may cause the refrigerant oil to deteriorate.
6. If there is a leak of gaseous refrigerant and the remaining refrigerant is exposed to an open flame, a poisonous gas
hydrofluoric acid may form. Keep workplace well ventilated.
CAUTION
Install new pipes immediately after removing old ones to keep moisture out of the refrigerant circuit.
The use of refrigerant that contains chloride, such as R22, will cause the refrigerating machine oil to deteriorate.

HWE10140 GB
[2] Necessary Tools and Materials
Prepare the following tools and materials necessary for installing and servicing the un it.
Tools for use with R410A (Adaptability of tools that are for use with R22 or R40 7C)
1. To be used exclusively with R410A (not to be used if used with R22 or R407C)
2. Tools and materials that may be used with R410A with some restrictions
3. Tools and materials that are used with R22 or R407C that may also be used with R410A
4. Tools and materials that must not be used with R410A
Tools for R410A must be handled with special care to keep moisture and dust from infiltrating the cycle.
Tools/Materials Use Notes

[3] Storage of Piping
1. Storage location
Store the piping materials indoors until they are ready to be installed (e.g., storage room on site or at the installer's premise).
If left outdoors, dust, dirt, or moisture may infiltrate and contaminate the pipe, resulting in malfunctions.
2. Sealing the pipe ends
Both ends of the pipes should be sealed until just before brazing.
Keep elbows and T-joints wrapped in plastic bags to keep dust, dirt, and moisture out.
The new refrigerant oil is more than ten times as hygroscopic as the conventional refrigerant oil, such as Suniso, and is more
likely to introduce moisture into the system. To prevent the deterioration of refrigerant oil and resultant compressor failure,
store piping materials with special care to keep moisture out.
[4] Pipe Processing
Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flanges.
Use a minimum amount of oil.
Use only ester oil, ether oil, and alkylbenzene.

HWE10140 GB
[5] Brazing
No changes have been made in the brazing procedures. Perform brazing with special care to keep foreign objects (such as oxide
scale, water, and dust) out of the refrigerant system.
Example: Inside the brazed connection
1. Items to be strictly observed
Do not conduct refrigerant piping work outdoors if raining.
Use non-oxidized solder.
Use a brazing material (BCuP-3) that requires no flux when brazing between copper pipes or between a copper pipe and
copper coupling.
If installed refrigerant pipes are not immediately connected to the equipment, then braze and seal both ends.
2. Reasons
Refrigerant oil for use with R410A is more than ten times as hygroscopic as the conventional refrigerant oil and is more likely
to introduce moisture into the system, requiring special care in handling to prevent malfunctions.
Do not use flux, which usually contains chloride and form sludge in the refrigerant circuit.
3. Notes
Do not use commercially available antioxidants because they may cause the pipes to corrode or refrigerating machine oil to
deteriorate.
Use of oxidized solder for brazing Use of non-oxidized solder for brazing

HWE10140 GB
[6] Air Tightness Test
No changes have been made in the detection method. Note that a refrigerant leak detector for R22 will not detect an R410A leak.
1. Items to be strictly observed
Pressurize the system with nitrogen to the design pressure (REPLACE MULTI Y(PUHY-RP): 3.3 MPa [479 psi]; REPLACE
MULTI R2 (PURY-RP): 3.6 MPa [523 psi]), and check for refrigerant leakage. Take the temperature fluctuations into account
when measuring pressure.
Refrigerant R410A must be charged in its liquid state (vs. gaseous state).
2. Reasons
Oxygen, if used for an air tightness test, poses a risk of explosion. (Only use nitrogen to check air tightness.)
Refrigerant R410A must be charged in its liquid state. If gaseous refrigerant in the cylinder is drawn out first, the composition
of the remaining refrigerant in the cylinder will change and become unsuitable for use.
3. Notes
R410A does not contain chloride, so leak detectors for use with older types of refrigerants will not detect an R410A leak. Be
sure to use a leak detector designed for use with R410A.

HWE10140 GB
[7] Vacuum Drying (Evacuation)
1. Vacuum pump with a reverse-flow check valve (Photo1)
To prevent the vacuum pump oil from flowing into the refrigerant circuit during power OFF or power failure, use a vacuum
pump with a reverse-flow check valve.
A reverse-flow check valve may also be added to the vacuum pump currently in use.
2. Standard of vacuum degree (Photo 2)
Use a vacuum pump that attains 0.5Torr(65Pa) or lower degree of vacuum after 5 minutes of operation, and connect it directly
to the vacuum gauge. Use a pump well-maintained with an appropriate lubricant. A poorly maintained vacuum pump may not
be able to attain the desired degree of vacuum.
3. Required precision of vacuum gauge
Use a vacuum gauge that registers a vacuum degree of 5Torr(650Pa) and measures at intervals of 1Torr(130Pa). (A recommended vacuum gauge is shown in Photo2.)
Do not use a commonly used gauge manifold because it cannot register a vacuum degree of 5Torr(650Pa).
4. Evacuation time
After the degree of vacuum has reached 5Torr(650Pa), evacuate for an additional 1 hour. (A thorough vacuum drying re-
moves moisture in the pipes.)
Verify that the vacuum degree has not risen by more than 1Torr(130Pa) 1hour after evacuation. A rise by less than
1Torr(130Pa) is acceptable.
If the vacuum is lost by more than 1Torr(130Pa), conduct evacuation, following the instructions in section 6. Special vacuum
drying.
5. Procedures for stopping vacuum pump
To prevent the reverse flow of vacuum pump oil, open the relief valve on the vacuum pump side, or draw in air by loosening
the charge hose, and then stop the operation.
The same procedures should be followed when stopping a vacuum pump with a reverse-flow check valve.
6. Special vacuum drying
When 5Torr(650Pa) or lower degree of vacuum cannot be attained after 3 hours of evacuation, it is likely that water has pen-
etrated the system or that there is a leak.
If water infiltrates the system, break the vacuum with nitrogen. Pressurize the system with nitrogen gas to
0.5kgf/cm
2
G(0.05MPa) and evacuate again. Repeat this cycle of pressurizing and evacuation either until the degree of vac-
uum below 5Torr(650Pa) is attained or until the pressure stops rising.
Only use nitrogen gas for vacuum breaking. (The use of oxygen may result in an explosion.)

7. Notes
To evacuate air from the entire system
Applying a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1
and 2) is not enough to attain the desired vacuum pressure.
Be sure to apply a vacuum through the check joints at the refrigerant service valve on the high and low pressure
sides (BV1 and 2) and also through the check joints on the high and low pressure sides (CJ1 and 2).
To evacuate air only from the outdoor units
Apply a vacuum through the check joints on the high and low pressure sides (CJ1, and 2).
To evacuate air from the indoor units and exte ns ion pipes
Apply a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1
and 2).

[8] Refrigerant Charging
1. Reasons
R410A is a pseudo-azeotropic HFC blend (boiling point R32=-52°C[-62°F], R125=-49°C[-52°F]) and can almost be han dled
the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder in the liquid
phase. If the refrigerant in the gaseous phase is drawn out, the composition of the remaining refrigeran t will change and become unsuitable for use.
2. Notes
When using a cylinder with a siphon, refrigerant is charged in the liquid state without the need for turning it upside down. Check
the type of the cylinder on the label before use.
[9] Remedies to be taken in case of a Refrigerant Leak
If the refrigerant leaks out, it may be replenished. The entire refrigerant does not need to be replaced. (Charge refrigerant in the
liquid state.)

[10] Characteristics of the Conventional and the New Refrigerants
1. Chemical property
As with R22, the new refrigerant (R410A) is low in toxicity and chemically stable nonflammable refrigerant.
However, because the specific gravity of vapor refrigerant is greater than that of air, leaked refrigerant in a closed room will
accumulate at the bottom of the room and may cause hypoxia.
If exposed to an open flame, refrigerant will generate poisonous gases. Do not perform installation or service work in a confined area.
*1 When CFC11 is used as a reference
*2 When CO
2
is used as a reference
2. Refrigerant composition
R410A is a pseudo-azeotropic HFC blend and can almost be handled the same way as a single refrigerant, such as R22. To
be safe, however, draw out the refrigerant from the cylinder in the liquid phase. If the refrigerant in the gaseous phase is drawn
out, the composition of the remaining refrigerant will change and become unsuitable for use.
If the refrigerant leaks out, it may be replenished. The entire refrigerant does not need to be replaced.
3. Pressure characteristics
The pressure in the system using R410A is 1.6 times as great as that in the system using R22.

[11] Notes on Refrigerating Machine Oil
1. Refrigerating machine oil in the HFC refrigerant system
HFC type refrigerants use a refrigerating machine oil different from that used in the R22 system.
Note that the ester oil used in the system has properties that are different from commercially available ester oil.
2. Effects of contaminants
*1
Refrigerating machine oil used in the HFC system must be handled with special care to keep contaminants out.
The table below shows the effect of contaminants in the refrigerating machine oil on the refrigeration cycle.

[2] Types and Maximum allowable Length of Cables
1. Wiring work
(1) Notes
1) Have all electrical work performed by an authorized electrician according to the local regulations and instructions in this manual.
2) Install external transmission cables at least 5cm [1-31/32"] away from the power supply cable to avoid noise interference.
(Do not put the control cable and power supply cable in the same conduit tube.)
3) Provide grounding for the outdoor unit as required.
4) Run the cable from the electric box of the indoor or outdoor unit in such way that the box is accessible for servicing.
5) Do not connect power supply wiring to the terminal block for transmission line. Doing so will damage the electronic components on the terminal block.
6) Use 2-core shielded cables as transmission cables.
Use a separate 2-core control cable for each refrigerant system. Do not use a single multiple-core cable to connect indoor
units that belong to different refrigerant systems. The use of a multiple-core cable may result in signal transmission errors and
malfunctions.
(2) Control wiring
Different types of control wiring are used for different systems.
Refer to section "[5] An Example of a System to which an MA Remote Controller is connected - [7] An Example of a System
to which both MA Remote Controller and ME Remote Controller are connected" before performi ng wiring work.
Types and maximum allowable length of cables
Control lines are categorized into 2 types: transmission line and remote controller line.
Use the appropriate type of cables and observe the maximum allowable length specified for a given system. If a given system
has a long transmission line or if a noise source is located near the unit, place the unit away from the noise source to reduce
noise interference.

Each indoor unit (or group of indoor units) can be controlled individually by setting SW 1-9 and 1-10.
*1. Do not cut off power to the outdoor unit. Cutting off the power supply to the outdoor unit will cut off the power supply to the
crankcase heater and may cause the compressor to malfunction when the unit is put back into operation.
*2. Not applicable to units with a built-in drain pump or humidifier.
*3. Models with a built-in drain pump cannot be turned on/off by the plug individually. All the units in the same refrigerant cir-
cuits will be turned on or off by the plug.
*4. Requires that the dipswitch settings for all the units in the group be made.
*5. To control the external input to and output from the air conditioners with the PLC software for general equipment via the

(8) Demand control
1) General outline of control
Demand control is performed by using the external signal input to the 1-2 and 1-3 pins of CN3D on the outdoor units (OC).
Between 2 and 4 steps of demand control is possible by setting Dip SW4-4 on the outdoor units (OC).
*1 If wrong sequence of steps are taken, the units may go into the Thermo-OFF (compressor stop) mode.
Ex) When switching from 100% to 50%
(Incorrect) 100%→0%→50% The units may go into the Thermo-OFF mode.
(Correct) 100%→75%→50%
*2 The percentage of the demand listed in the table above is an approximate value based on the compressor volume and does
not necessarily correspond with the actual capacity.
*3 Notes on using demand control in combination with the low-noise mode
To enable the low-noise mode, it is necessary to short-circuit 1-2 pin of CN3D on the outdoor un it whose SW4-4 is set to OFF.
2) Contact input and control content
2-step demand control
The same control as the Thermo-OFF is performed by closing 1-3 pin of CN3D.

[6] An Example of a System to which an ME Remote Controller is connected
(1) Sample control wiring
(2) Cautions
1) ME remote controller and MA remote controller cannot both
be connected to the same group of indoor units.
2) No more than 2 ME remote controllers can be connected to
a group of indoor units.
3) Do not connect the terminal blocks (TB5) on the indoor units
that are connected to different outdoor units with each other.
4) Replace the power jumper connector of the control board
from CN41 to CN40 on only one of the outdoor units.
5) Provide an electrical path to ground for the S terminal on the
terminal block for centralized contro l on only one of the outdoor units.
6) When the number of the connected indoor units is as shown
in the table below, one or more transmission boosters (sold
separately) are required.
To connect two transmission boosters, connect them in parallel. (Observe the maximum number of connectable indoor
units that are listed in the specifications for each outdoor
unit.)
The left table shows the number of transmission boosters
that is required by the system with three BC controllers. For
each BC controller that is subtracted from the above-mentioned system, two additional indoor units can be connected .
7) When a power supply unit is connected to the transmission
line for centralized control, leave the power jumper connector on CN41 as it is (factory setting).

[8] Restrictions on Pipe Length
1. Determining the reusability of the existing piping
Mitsubishi Electric Corporation cannot be held responsibility for the problems arising from the use of the existing pipes. Before
installing the new air conditioning system, the existing piping system must be checked for refrigerant gas leaks, strength (material/thickness), and for corrosion.
Major points to consider when evaluating the reusability of the existing piping
(1) Repl acing City Multi units with Replace Multi units
The existing piping system can be reused unless there have been problems with the system.
(Make sure that the system has not experienced frequent malfunctions due to refrigerant gas leaks or required additional refrigerant charge frequently.)
1) Replacing the existing units with Replace Multi units with the same capacity→The existing pipes can be used as they are.
2) Replacing the existing units with Replace Multi units with different capacity→Make sure that the existing piping system meet
the piping size, piping length, and maximum vertical separation requirements for the Replace Multi system.
(2) Replacing units other than City Multi units with Replace Multi units
1) Make sure that the existing packaged air conditioning system is operating normally.
(Make sure that the system has not experienced frequent malfunctions due to refrigerant gas leaks or required additional refrigerant charge frequently.)
2) Find out the type of the refrigerant oil used in the existing system.
Suniso, MS, HAB, Barrel Freeze, and Freol are acceptable. If other types of refrigerant oil is used, check on the compatibility.
3) T-shaped branch pipes can be reused.
Branch pipes that are subject to pressure loss (e.g., Mr. SLIM multi distributor) cannot be used in the Replace Multi system.
They should be replaced with new branch pipes.
Using the manufacturer name, model name, and the number of units connected to estimate the branching types and pipe
sizes.
4) Make sure that the existing piping system meet the piping size, piping length, and maximum vertical separation requirements
for the Replace Multi system.

The figures in the radial thickness column are based on the
Japanese standards and provided only as a reference. Use
pipes that meet the local standards.
WARNING
Do not let refrigerant (R410A) leak in the presence of an open flame or other heat source. If refrigerant comes in
contact with an open flame, it will break down and produce toxic gases. Do not weld in a confined space. Perform a
leak test upon completion of refrigerant pipe installation.
WARNING
When installing or relocating the unit, check that no substance other than the specified refrigerant (R410A) is present
in the refrigerant circuit.
Presence of foreign substance or air can cause abnormal pressure rise or explosion.
CAUTION
Use refrigerant piping made of phosphorus deoxidized copper. Keep the inner and outer surfaces of the pipes clean
and free of such contaminants as sulfur, oxides, dust, dirt, shaving particles, oil, and moisture.
Contaminants in the refrigerant piping may cause the refrigerant oil to deteriorate.
[ II Restrictions ]
- 48 -
HWE10140 GB
CAUTION
Charge refrigerant in the liquid state.
If gaseous refrigerant is drawn out of the cylinder first, the composition of the refrigerant in the cylinder will change
and become unsuitable for use. It will also lead to performance loss.
CAUTION
Store the piping materials indoors, and keep both ends of the pipes sealed until immediately before brazing.
(Keep elbows and other joints in plastic bags.)
Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerant oil to deteriorate or damage the
compressor.
CAUTION
Do not use a charging cylinder.
The use of a charging cylinder will change the composition of the refrigerant in the cylinder. It will also lead to per-
formance loss.

1) To connect the P100 through P140 models of indoor units, use an optional junction pipe kit (Model: CMY-R160-J1) and merge
the two ports before connecting them. (In that case, set DIP SW4-6 on the BC controller to ON.)
It is also possible to connect the P100 through P140 models of units to a port, although the cooling performance will somewhat
decrease. (In that case, set DIP SW4-6 on the BC controller to OFF.)
(The factory setting for DIP SW4-6 is OFF. )
2) Do not connect the P200 or P250 models of indoor units and other models of indoor units at the same port.
3) All the units that are connected to the same ports can only be operated in the same operation mode (cooling/heating).
4) Do not use the existing Y-shaped twinning pipe.
Make sure to change the twinning pipe to the one for use with R410A.
If the existing twinning pipe is T-shaped, there is no need to change.

1) A system that requires more than 16 BC controller ports requires two or three BC controllers (main and sub), and three pipes
will be used between the main and the sub BC controllers.
2) When connecting two sub BC controllers, observe the maximum allowable length in the table above.
3) When connecting two sub BC controllers, install them in parallel.
4) To connect the P100 through P140 models of indoor units, use an optional junction pipe kit (Model: CMY-R160-J1) and merge
the two ports before connecting them. (In that case, set DIP SW4-6 on the BC controller to ON.)
It is also possible to connect the P100 through P140 models of units to a port, although the cooling performance will somewhat
decrease. (In that case, set DIP SW4-6 on the BC controller to OFF.)
(The factory setting for DIP SW4-6 is OFF. )
5) Do not connect the P200 or P250 models of indoor units and other models of indoor units at the same port.
6) All the units that are connected to the same ports can only be operated in the same operation mode (cooling/heating).
7) The maximum capacity of the indoor units that is connectable to the CMB-P-V-GB1 types of sub BC controllers is P350 or
below (when two GB1 type controllers are connected P350 or below for both combined).
The maximum total capacity of indoor units that is connectable to the sub BC controller CMB-P1016V-HB1 is P350 or below.
If at least one CMB-P1016V-HB1 unit is connected, the maximum total capacity of connectable indoor units to a system with
two sub controllers is P450 or below.
8) Do not use the existing Y-shaped twinning pipe.
Make sure to change the twinning pipe to the one for use with R410A.
If the existing twinning pipe is T-shaped, there is no need to change.

In the remote controller function selection mode, the settings for four types of functions can be made or changed as necessary.
4) Narrowed preset temperature range mode
The default temperature ranges are 19 C to 30 C in the cooling/dry mode and 17 C to 28 C in the heating mode and 19 C to 28 C in the auto mode.
By changing these ranges (raising the lower limit for the cooling/dry mode and lowering the upper limit for the heating mode), energy can be saved.
When making the temperature range setting on the simultaneous cooling/heating type units that supports the automatic operation mode to save on
energy consumption, enable the Skip-Auto-Mode setting to make the automatic operation mode unselectable. If the automatic operation mode is
selected, the energy-saving function may not work properly.
When connected to the air conditioning units that do not support the automatic operation mode, the setting for the Skip-Auto-Mode, restricted preset
temperature range mode (AUTO), and operation mode display selection mode are invalid. If an attempt is made to change the preset temperature range,
“LIMIT TEMP .” appears on the display .
