Installation Manual and Operation Manual must be given to the user for keeping.
These manuals must be passed on to subsequent users.
: Indicates a part which must be grounded.
Warning:
Carefully read the labels afxed to the main unit.
Warning:
• The unit must not be installed by the user. Ask a dealer or an authorized
technician to install the unit. If the unit is installed incorrectly, water leakage, electric shock, or re may result.
• For installation work, follow the instructions in the Installation Manual and
use tools and pipe components specically made for use with R410A refrigerant. The R410A refrigerant in the HFC system is pressurized 1.6 times the
pressure of usual refrigerants. If pipe components not designed for R410A
refrigerant are used and the unit is not installed correctly, the pipes may
burst and cause damage or injuries. In addition, water leakage, electric
shock, or re may result.
• The unit must be installed according to the instructions in order to minimize
the risk of damage from earthquakes, typhoons, or strong winds. An incorrectly installed unit may fall down and cause damage or injuries.
• The unit must be securely installed on a structure that can sustain its
weight. If the unit is mounted on an unstable structure, it may fall down and
cause damage or injuries.
• If the air conditioner is installed in a small room, measures must be taken to
prevent the refrigerant concentration in the room from exceeding the safety
limit in the event of refrigerant leakage. Consult a dealer regarding the ap-
propriate measures to prevent the allowable concentration from being exceeded. Should the refrigerant leak and cause the concentration limit to be
exceeded, hazards due to lack of oxygen in the room may result.
• Ventilate the room if refrigerant leaks during operation. If refrigerant comes
into contact with a ame, poisonous gases will be released.
• All electric work must be performed by a qualied technician according to
local regulations and the instructions given in this manual. The units must
be powered by dedicated power lines and the correct voltage and circuit
breakers must be used. Power lines with insufcient capacity or incorrect
electrical work may result in electric shock or re.
• Use C1220 copper phosphorus, for copper and copper alloy seamless
pipes, to connect the refrigerant pipes. If the pipes are not connected cor-
rectly, the unit will not be properly grounded and electric shock may result.
1.1. Before installation
Caution:
• Do not use the unit in an unusual environment. If the air conditioner is installed in areas exposed to steam, volatile oil (including machine oil), or
sulfuric gas, areas exposed to high salt content such as the seaside, or
areas where the unit will be covered by snow, the performance can be signicantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced,
ow, or accumulate. If combustible gas accumulates around the unit, re or
explosion may result.
• 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.
• Use only specied cables for wiring. The wiring connections must be made
securely with no tension applied on the terminal connections. Also, never
splice the cables for wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a re.
• The terminal block cover panel of the outdoor unit must be rmly attached.
If the cover panel is mounted incorrectly and dust and moisture enter the
unit, electric shock or re may result.
• When installing or relocating, or servicing the air conditioner, use only the
specied refrigerant (R410A) to charge the refrigerant lines. Do not mix it
with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.
The use of any refrigerant other than that specied for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
• Use only accessories authorized by Mitsubishi Electric and ask a dealer
or an authorized technician to install them. If accessories are incorrectly
installed, water leakage, electric shock, or re may result.
• Do not alter the unit. Consult a dealer for repairs. If alterations or repairs are
not performed correctly, water leakage, electric shock, or re may result.
• The user should never attempt to repair the unit or transfer it to another
location. If the unit is installed incorrectly, water leakage, electric shock, or
re may result. If the air conditioner must be repaired or moved, ask a dealer
or an authorized technician.
• After installation has been completed, check for refrigerant leaks. If refrigerant leaks into the room and comes into contact with the ame of a heater or
portable cooking range, poisonous gases will be released.
• The outdoor unit produces condensation during the heating operation.
Make sure to provide drainage around the outdoor unit if such condensation is likely to cause damage.
• When installing the unit in a hospital or communications ofce, be prepared
for noise and electronic interference. Inverters, home appliances, high-
frequency medical equipment, and radio communications equipment can
cause the air conditioner to malfunction or breakdown. The air conditioner
may also affect medical equipment, disturbing medical care, and communications equipment, harming the screen display quality.

1. Safety precautions
1.2. Before installation (relocation)
Caution:
• Be extremely careful when transporting or installing the units. Two or more
persons are needed to handle the unit, as it weighs 20 kg or more. Do not
grasp the packaging bands. Wear protective gloves to remove the unit from
the packaging and to move it, as you can injure your hands on the ns or
the edge of other parts.
• Be sure to safely dispose of the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause stabs or other
injuries.
1.3. Before electric work
Caution:
• Be sure to install circuit breakers. If not installed, electric shock may result.
• For the power lines, use standard cables of sufcient capacity. Otherwise,
a short circuit, overheating, or re may result.
• When installing the power lines, do not apply tension to the cables. If the
connections are loosened, the cables can snap or break and overheating or
re may result.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting operation. Starting operation just after turning on the power switch can severely
damage the internal parts. Keep the main power switch turned on during the
operation season.
• Before starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.
• The base and attachments of the outdoor unit must be periodically checked
for looseness, cracks or other damage. If such defects are left uncorrected,
the unit may fall down and cause damage or injuries.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all are nuts to specication using a torque wrench. If tightened too
much, the are nut can break after an extended period and refrigerant can
leak out.
• Be sure to ground the unit. Do not connect the ground wire to gas or water
pipes, lightning rods, or telephone grounding lines. If the unit is not properly grounded, electric shock may result.
• Use circuit breakers (ground fault interrupter, isolating switch (+B fuse),
and molded case circuit breaker) with the specied capacity. If the circuit
breaker capacity is larger than the specied capacity, breakdown or re
may result.
• Do not touch any switch with wet hands. Electric shock may result.
• Do not touch the refrigerant pipes with bare hands during operation. The
refrigerant pipes are hot or cold depending on the condition of the owing
refrigerant. If you touch the pipes, burns or frostbite may result.
• After stopping operation, be sure to wait at least ve minutes before turning off the main power switch. Otherwise, water leakage or breakdown may
result.
1.5. Using R410A refrigerant air conditioners
Caution:
• Use C1220 copper phosphorus, for copper and copper alloy seamless
pipes, to connect the refrigerant pipes. Make sure the insides of the pipes
are clean and do not contain any harmful contaminants such as sulfuric
compounds, oxidants, debris, or dust. Use pipes with the specied thickness. (Refer to 4.1.) Note the following if reusing existing pipes that carried
R22 refrigerant.
- Replace the existing are nuts and are the ared sections again.
- Do not use thin pipes. (Refer to 4.1.)
• Store the pipes to be used during installation indoors and keep both ends
of the pipes sealed until just before brazing. (Leave elbow joints, etc. in
their packaging.) If dust, debris, or moisture enters the refrigerant lines, oil
deterioration or compressor breakdown may result.
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration
oil applied to the ared sections. If mineral oil is mixed in the refrigeration
oil, oil deterioration may result.

Fig. 1-1
• Do not use refrigerant other than R410A refrigerant. If another refrigerant is
used, the chlorine will cause the oil to deteriorate.
• Use the following tools specically designed for use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant. Contact your
nearest dealer for any questions.
Gauge manifold Flare tool
Charge hose Size adjustment gauge
Gas leak detector Vacuum pump adapter
Torque wrench Electronic refrigerant charging scale
• Be sure to use the correct tools. If dust, debris, or moisture enters the refrigerant lines, refrigeration oil deterioration may result.
• Do not use a charging cylinder. If a charging cylinder is used, the composition of the refrigerant will change and the efciency will be lowered.

2.2. Choosing the outdoor unit installation location
• Avoid locations exposed to direct sunlight or other sources of heat.
• Select a location from which noise emitted by the unit will not inconvenience
neighbors.
• Select a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, ow, or accumulate.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation location or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airow
and a malfunction may result.
• Avoid locations exposed to oil, steam, or sulfuric gas.
• Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or ngers may be pinched.

1 Perform refrigerant piping connections for the indoor/outdoor unit when the out-
door unit’s stop valve is completely closed.
2 Vacuum-purge air from the indoor unit and the connection piping.
3 After connecting the refrigerant pipes, check the connected pipes and the indoor
unit for gas leaks. (Refer to 4.4. Refrigerant pipe airtight testing method)
4 A high-performance vacuum pump is used at the stop valve service port to main-
tain a vacuum for an adequate time (at least one hour after reaching –101 kPa (5
Torr)) in order to vacuum dry the inside of the pipes. Always check the degree of
vacuum at the gauge manifold. If there is any moisture left in the pipe, the degree
of vacuum is sometimes not reached with short-time vacuum application.
After vacuum drying, completely open the stop valves (both liquid and gas) for the
outdoor unit. This completely links the indoor and outdoor refrigerant circuits.
If the vacuum drying is inadequate, air and water vapor remain in the refrigerant

circuits and can cause abnormal rise of high pressure, abnormal drop of low
pressure, deterioration of the refrigerating machine oil due to moisture, etc.
• If the stop valves are left closed and the unit is operated, the compressor and
control valves will be damaged.
• Use a leak detector or soapy water to check for gas leaks at the pipe connection sections of the outdoor unit.
• Do not use the refrigerant from the unit to purge air from the refrigerant lines.
• After the valve work is completed, tighten the valve caps to the correct torque:
20 to 25 N·m (200 to 250 kgf·cm).
Failure to replace and tighten the caps may result in refrigerant leakage. In
addition, do not damage the insides of the valve caps as they act as a seal to
prevent refrigerant leakage.
5 Use sealant to seal the ends of the thermal insulation around the pipe connection
sections to prevent water from entering the thermal insulation.

4.4. Refrigerant pipe airtight testing method (Fig.4-5)
(1)
Connect the testing tools.
• Make sure the stop valves
• Add pressure to the refrigerant lines through the service port C of the liquid
stop valve A.
(2)
Do not add pressure to the specied pressure all at once; add pressure little by
little.
1 Pressurize to 0.5 MPa (5 kgf/cm
sure does not decrease.
2 Pressurize to 1.5 MPa (15 kgf/cm
pressure does not decrease.
3 Pressurize to 4.15 MPa (41.5 kgf/cm
perature and refrigerant pressure.
(3)
If the specied pressure holds for about one day and does not decrease, the pipes
have passed the test and there are no leaks.
• If the surrounding temperature changes by 1 °C, the pressure will change by
about 0.01 MPa (0.1 kgf/cm
(4)
If the pressure decreases in steps (2) or (3), there is a gas leak. Look for the
source of the gas leak.
4.5. Stop valve opening method
The stop valve opening method varies according to the outdoor unit model. Use the
appropriate method to open the stop valves.

2 Make sure that the stop valve is open completely, push in the handle and rotate
the cap back to its original position.
Refrigerant pipes are protectively wrapped
• The pipes can be protectively wrapped up to a diameter of ø90 before or after
connecting the pipes. Cut out the knockout in the pipe cover following the groove
and wrap the pipes.
Pipe inlet gap
• Use putty or sealant to seal the pipe inlet around the pipes so that no gaps remain.
(If the gaps are not closed, noise may be emitted or water and dust will enter the
unit and breakdown may result.)

Do not further tighten sections A and B together after tightening section A.
Warning:
When installing the unit, securely connect the refrigerant pipes before starting
the compressor.

4.6. Addition of refrigerant
• Additional charging is not necessary if the pipe length does not exceed 30 m.
• If the pipe length exceeds 30m, charge the unit with additional R410A refrigerant
according to the permitted pipe lengths in the chart below.
* When the unit is stopped, charge the unit with the additional refrigerant through
the liquid stop valve after the pipe extensions and indoor unit have been vacuumized.
When the unit is operating, add refrigerant to the gas check valve using a
safety charger. Do not add liquid refrigerant directly to the check valve.
* After charging the unit with refrigerant, note the added refrigerant amount on
the service label (attached to the unit).
Refer to the “1.5. Using R410A refrigerant air conditioners” for more informa-
tion.
