•Exercise caution when using any auxiliary heat source and follow all third
party manufacturer instructions and safety guidelines for installation and
usage.
• Any auxiliary heat source connected to this unit via the CN24 connection
must have an independent temperature control mechanism. Failure to
install and maintain such temperature control mechanism may void the
warranty for this unit.
•Mitsubishi Electric shall not bear any warranty obligation or other liability
for any damage or loss in connection with such third party auxiliary
heaters.
• The installer and system specialist shall secure safety against leakage
according to local regulation or standards.
- The instructions in this manual may be applicable if local regulations are not
available.
• Pay a special attention to the place, such as a basement, etc. where
refrigeration gas can stay, since refrigeration is heavier than the air.
• Children should be supervised to ensure that they do not play with the
appliance.
• This appliance is intended to be used by expert or trained users in shops,
in light industry and on farms, or for commercial use by lay persons.
1.2. Precautions for devices that use R410A
refrigerant
Caution:
• Do not use the existing refrigerant piping.
- The old refrigerant and refrigerator oil in the existing piping contains a large
amount of chlorine which may cause the refrigerator oil of the new unit to
deteriorate.
•Use refrigerant piping made of C1220 (Cu-DHP) phosphorus deoxidized
copper as specied in the JIS H3300 “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
residual 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 trouble may result.
•Use liquid refrigerant to ll the system.
- If gas refrigerant is used to seal 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 used, the chlorine in the refrigerant may
cause the refrigerator oil to deteriorate.
•Use a vacuum pump with a reverse ow check valve.
- Thevacuumpumpoilmayowbackintotherefrigerantcycleandcausethe
refrigerator oil to deteriorate.
• Do not use the following tools that are used with conventional refrigerants.
(Gauge manifold, charge hose, gas leak detector, reverse ow check valve,
refrigerant charge base, vacuum gauge, refrigerant recovery equipment)
- If the conventional refrigerant and refrigerator oil are mixed in the R410A, the
refrigerant may deteriorated.
- If water is mixed in the R410A, the refrigerator 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 in the refrigerant cycle, the refrigerant may
deteriorate.
1.3. Before getting installed
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,sulfuricsmoke,etc.cansignicantlyreducetheperformanceofthe
air conditioner or damage its parts.
• When installing the unit in a hospital, communication station, or similar
place, provide sucient protection against noise.
- The 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
mayaectsuchequipmentbycreatingnoisethatdisturbsmedicaltreatmentor
image broadcasting.
• Do not install the unit on a structure that may cause leakage.
- 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.
• The indoor units should be installed on the ceiling at least 2.5 m [9 ft] from
the oor.
1.4. Before getting installed (moved) -
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.
• Install the power cable so that tension is not applied to the cable.
- Tensionmaycausethecabletobreakandgenerateheatandcauseare.
• Install a leak circuit breaker, as required.
- If a leak circuit breaker is not installed, electric shock may result.
•Use power line cables of sucient current carrying capacity and rating.
- Cablesthataretoosmallmayleak,generateheat,andcauseare.
•Use only a circuit breaker and fuse of the specied capacity.
- A fuse or circuit breaker of a larger capacity or a steel or copper wire may result
inageneralunitfailureorre.
• 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 product transportation.
- Only one person should not carry the product if it weighs more than 20 kg [45
LBS].
- Some products use PP bands for packaging. Do not use any PP bands for a
means of transportation. It is dangerous.
- Donottouchtheheatexchangerns.Doingsomaycutyourngers.
- Whentransportingtheoutdoorunit,suspenditatthespeciedpositionson
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 was not torn apart, they face
theriskofsuocation.
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 severe damage to internal parts. Keep the power switch turned on
during the operational season.
•Do not touch the switches with wet ngers.
- Touchingaswitchwithwetngerscancauseelectricshock.
• Do not touch the refrigerant pipes during and immediately after operation.

7. Connecting refrigerant pipes and drain pipes
7.1. Refrigerant piping work
This piping work must be done in accordance with the installation manuals for both
outdoor unit and BC controller (simultaneous cooling and heating series R2).
•Series R2 is designed to operate in a system that the refrigerant pipe from an
outdoor unit is received by BC controller and branches at the BC controller to
connect between indoor units.
•Forconstraintsonpipelengthandallowabledierenceofelevation,refertothe
outdoor unit manual.
•The method of pipe connection is brazing connection.
Caution:
• Install the refrigerant piping for the indoor unit in accordance with the
following.
1. Cut the tip of the indoor unit piping, remove the gas, and then remove the brazed
cap.
[Fig. 7.1.1] (P.4)
ACut here
BRemove brazed cap
2. Pull out the thermal insulation on the site refrigerant piping, braze the unit piping,
and replace the insulation in its original position.
Wrap the piping with insulating tape.
Note:
• When blazing the refrigerant pipes, be sure to blaze, after covering a
wet cloth to the pipes of the units in order to prevent it from burning and
shrinking by heat.
[Fig. 7.1.2] (P.4)
ACool by a wet cloth
• Pay strict attention when wrapping the copper piping since wrapping the
piping may cause condensation instead of preventing it.

Cautions On Refrigerant Piping
►Be sure to use non-oxidative brazing for brazing to ensure that no foreign
matter or moisture enter into the pipe.
► Be sure to apply refrigerating machine oil over the are connection seating
surface and tighten the connection using a double spanner.
►Provide a metal brace to support the refrigerant pipe so that no load is
imparted to the indoor unit end pipe. This metal brace should be provided
50 cm away from the indoor unit’s are connection.
Warning:
Do not use refrigerant other than the type indicated in the manuals provided
with the unit and on the nameplate.
- Doingsomaycausetheunitorpipestoburst,orresultinexplosionorreduring
use, during repair, or at the time of disposal of the unit.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held responsible for
malfunctions or accidents resulting from the use of the wrong type of refrigerant.
Caution:
•Use refrigerant piping made of C1220 (Cu-DHP) phosphorus deoxidized
copper as specied in the JIS H3300 “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.
• Never use existing refrigerant piping.
- The large amount of chlorine in conventional refrigerant and refrigerator 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.
• Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil
to coat ares and ange connections. (For models using R410A or R407C)
- The refrigerant used in the unit is highly hygroscopic and mixes with water and
will degrade the refrigerator oil.
7.2. Drain piping work
•Ensure that the drain piping is downward (pitch of more than 1/100) to the
outdoor (discharge) side. Do not provide any trap or irregularity on the way.
•Ensure that any cross-wise drain piping is less than 20 m [65 ft] (excluding
thedierenceofelevation).Ifthedrainpipingislong,providemetalbracesto
prevent it from waving. Never provide any air vent pipe. Otherwise drain may be
ejected.
•Use a hard vinyl chloride pipe O.D. ø32 mm [1-1/4 in] for drain piping.
•Ensurethatcollectedpipesare10cm[3-15/16in]lowerthantheunitbody’s
drain port.
•Do not provide any odor trap at the drain discharge port.
•Put the end of the drain piping in a position where no odor is generated.
•Do not put the end of the drain piping in any drain where ionic gases are
generated.

Caution:
When the duct is connected to the inlet at the bottom of the unit, the sound
pressure level will be greater by approximately 10 dB than when the duct is
connected to the inlet at the back of the unit.
For this reason, it is recommended to connect the duct to the back inlet. When
using the inlet at the bottom of the unit, oset the position of the inlet on the
indoor unit relative to the inlet on the ceiling as shown in Figures <A> and <B>
to minimize noise.

Caution:
• To reduce the risk of injury from metal sheet edges, wear protective gloves.
• Keep the distance between the inlet grille and the fan over 850 mm
[33-1/2 in].
If it is less than 850 mm [33-1/2 in], install a safety guard not to touch the
fan.
•Install sucient thermal insulation to prevent condensation forming on
outlet duct anges and outlet ducts.
• To avoid electrical noise interference, do not run transmission lines at the
bottom of the unit.
•The noise from the intake will increase dramatically if intake is tted
directly beneath the main body. Intake should therefore be installed as far
away from the main body as possible.
Particular care is required when using it with bottom inlet specications.
When the plate is attached on
the rear side, it exceeds the
height of the rear body panel.
Replicate the plate along the slit
when there is not enough room
above for the entire unit.
Screw holes are hidden under
the insulation. Screw through
the insulation to screw the plate
down.

9. Electrical wiring
Precautions on electrical wiring
Warning:
Electrical work should be done by qualied electrical engineers in accordance
with “Engineering Standards For Electrical Installation” and supplied
installation manuals. Special circuits should also be used. If the power circuit
lacks capacity or has an installation failure, it may cause a risk of electric
shock or re.
1. Be sure to install an earth leakage breaker to the power.
Use an earth leakage breaker with a sensitivity of less than 30 mA 0.1 s.
2. Install the unit to prevent that any of the control circuit cables (remote controller,
transmission cables) is brought in direct contact with the power cable outside the
unit.
3. Ensure that there is no slack on all wire connections.
4. Some cables (power, remote controller, transmission cables) above the ceiling
may be bitten by mice. Use as many metal pipes as possible to insert the cables
into them for protection.
5. Never connect the power cable to leads for the transmission cables. Otherwise
the cables would be broken.
6. Be sure to connect control cables to the indoor unit, remote controller, and the
outdoor unit.
7. Put the unit to the ground on the outdoor unit side.
8. Select control cables from the conditions given in page 13.
9. Perform wiring in compliance with the safety regulations detailed in
UL60335-2-40.
Caution:
• Be sure to put the unit to the ground on the outdoor unit side. Do not
connect the earth cable to any gas pipe, water pipe, lightening rod, or
telephone earth cable. Incomplete grounding may cause a risk of electric
shock.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualied persons in order to avoid a hazard.

5. After wiring is complete, make sure again that there is no slack on the
connections, and attach the cover onto the terminal box in the reverse order of
removal.
Caution:
Wire the power supply so that no tension is imparted. Otherwise
disconnection, heating or re result.
Notes:
• Do not pinch the cables or wires when attaching the terminal box cover.
Doing so may cause a risk of disconnection.
• When accommodating the terminal box, make sure that the connectors on
the box side are not removed. If removed, it cannot operate normally.
9.4. External I/O specications
Caution:
1. Wiring should be covered by insulation tube with supplementary insulation.
2. Use relays or switches with IEC or equivalent standard.
3. The electric strength between accessible parts and control circuit should
have 2750 V or more.
9.5. Selecting the external static pressure
Five levels of external static pressure are available for selection.
Set the setting either by using the switches on the control board (SW21-1, SW21-2, and SW21-5) or from the function selection screen on the remote controller.
[Fig. 9.5.1] (P.6)
<Indoor controller board>
Notes:
• When the static pressure setting was set from the remote controller, the actual setting and the switch setting on the control board may not match because the
latest setting from the remote controller overrides the previous setting. To check the latest static pressure setting, check it on the remote controller, not on the
switch.
• If the static pressure setting for the duct is lower than that for the unit, the fan of the unit may repeat start/stop, and the outdoor unit may remain in a stopped
state. Match the static pressure settings for the unit to that for the duct.

settings has been changed.
9.6. Setting addresses
(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P.6)
<Indoor controller board>
•There are two types of rotary switch setting available: setting addresses 1 to 9
and over 10, and setting branch numbers.
1 How to set addresses
Example: If Address is “3”, remain SW12 (for over 10) at “0”, and match
SW11(for 1 to 9) with “3”.
2 How to set branch numbers SW14 (Series R2 only)
The branch number assigned to each indoor unit is the port number of the
BC controller to which the indoor unit is connected.
Leave it to “0” on the non-R2 series of units.
•The rotary switches are all set to “0” when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
•The determination of indoor unit addresses varies with the system at site. Set
them referring to the Data Book.
9.7. Sensing room temperature with the built-
in sensor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote controller,
set SW1-1 on the control board to “ON”. The setting of SW1-7 and SW1-8 as
necessaryalsomakesitpossibletoadjusttheairowatatimewhentheheating
thermometer is OFF.
9.8. Changing the power voltage setting
(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P.6)
Please set the switch SW21 according to the power voltage.
•Set SW21-6 to OFF side when the power supply is 230 volts.
•When the power supply is 208 volts, set SW21-6 to ON side.
