1SAFETY PRECAUTIONS

and install the unit at the specified place.- Improper installation may cause the unit to topple and result in

injury. Always use an air cleaner, humidifier, electric heater, and other

accessories specified by Mitsubishi Electric.- Ask an authorized technician to install the accessories. Improper

installation by the user may result in water leakage, electric shock,or fire.

Never repair the unit. If the air conditioner must be repaired,consult the dealer.- If the unit is repaired improperly, water leakage, electric shock, or

fire may result. Do not touch the heat exchanger fins.

- Improper handling may result in injury. If refrigerant gas leaks during installation work, ventilate the

room.- If the refrigerant gas comes into contact with a flame, poisonous

gases will be released. Install the air conditioner according to this Installation Manual.

- If the unit is installed improperly, water leakage, electric shock, orfire may result.

Have all electric work done by a licensed electrician accordingto Electric Facility Engineering Standard and Interior WireRegulationsand the instructions given in this manual and al-ways use a special circuit.- If the power source capacity is inadequate or electric work is per-

formed improperly, electric shock and fire may result.

Securely install the cover of control box and the panel.- If the cover and panel are not installed properly,dust or water may

enter the outdoor unit and fire or electric shock may result. When installing and moving the air conditioner to another site,

do not charge it with a refrigerant different from the refrigerantspecified on the unit.- If a different refrigerant or air is mixed with the original refrigerant,

the refrigerant cycle may malfunction and the unit may be dam-aged.

If the air conditioner is installed in a small room, measuresmust be taken to prevent the refrigerant concentration fromexceeding the safety limit even if the refrigerant should leak.- Consult the dealer regarding the appropriate measures to pre-

vent the safety limit from being exceeded. Should the refrigerantleak and cause the safety limit to be exceeded, hazards due tolack of oxygen in the room could result.

When moving and reinstalling the air conditioner, consult thedealer or an authorized technician.- If the air conditioner is installed improperly, water leakage, elec-

tric shock, or fire may result. After completing installation work, make sure that refrigerant

gas is not leaking.- If the refrigerant gas leaks and is exposed to a fan heater, stove,

oven, or other heat source, it may generate noxious gases. Do not reconstruct or change the settings of the protection

devices.- If the pressure switch, thermal switch, or other protection device

is shorted and operated forcibly, or parts other than those specifiedby Mitsubishi Electric are used, fire or explosion may result.

1. Before installation and electric works Before installing the unit, make sure you read all the

Safety precautions.s The Safety precautions provide very important

points regarding safety. Make sure you follow them.s This equipment may cause the adverse effect on the

same supply system.s Please report to or take consent by the supply au-

thority before connection to the system.

Symbols used in the textWarning:

Describes precautions that should be observed to prevent dangerof injury or death to the user.

Caution:Describes precautions that should be observed to prevent damageto the unit.

Symbols used in the illustrations: Indicates an action that must be avoided.

: Indicates that important instructions must be followed.

: Indicates a part which must be grounded.: Indicates that caution should be taken with rotating parts. (This

symbol is displayed on the main unit label.) : Beware of electric shock (This symbol is displayed on the main

unit label.)

Warning:Carefully read the labels affixed to the main unit.

Warning: Ask the dealer or an authorized technician to install the air con-

ditioner.- Improper installation by the user may result in water leakage, elec-

tric shock, or fire. Install the air unit at a place that can withstand its weight.

- Inadequate strength may cause the unit to fall down, resulting ininjuries.

Use the specified cables for wiring. Make the connections se-curely so that the outside force of the cable is not applied to theterminals.- Inadequate connection and fastening may generate heat and cause

a fire. Prepare for typhoons and other strong winds and earthquakes

Keep the electric parts away from water (washing water etc.).- It might result in electric shock, catching fire or smoke.

To dispose of this product, consult your dealer. Do not use a leak detection additive.

22. Precautions for devices that use R410A or R407C refrigerant

Caution: Do not use the existing refrigerant piping.

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

Use refrigerant piping made of C1220 (Cu-DHP) phosphorusdeoxidized copper as specified in the *JIS H3300 Copper andcopper alloy seamless pipes and tubes. In addition, be surethat the inner and outer surfaces of the pipes are clean andfree 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.*JIS: Japanese Industrial Standard

Store the piping to be used during installation indoors and keepboth ends of the piping sealed until just before brazing. (Storeelbows 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 ester oil, ether oil or alkylbenzene (small amount) as the

refrigerator oil to coat flares and flange connections.- The refrigerator oil will degrade if it is mixed with a large amount of

mineral oil. Use liquid refrigerant to fill the system.

- If gas refrigerant is used to seal the system, the composition ofthe refrigerant in the cylinder will change and performance maydrop.

Do not use a refrig- If another refrigerant (R22, etc.) is used, the chlorine in the refrig-

erant may cause the refrigerator oil to deteriorate. Use a vacuum pump with a reverse flow check valve..

- The vacuum pump oil may flow back into the refrigerant cycle andcause the refrigerator oil to deteriorate.

Do not use the following tools that are used with conventionalrefrigerants.(Gauge manifold, charge hose, gas leak detector, reverse flowcheck valve, refrigerant charge base, vacuum gauge, refriger-ant recovery equipment)- If the conventional refrigerant and refrigerator oil are mixed in the

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.

erant other than R410A or R407C.

R410A or R407C, the refrigerant may deteriorated.- If

deteriorate.water is mixed in the R410A or R407C, the refrigerator oil may

- Since R410A or R407C does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it.

Note: 1 Cooling/Heating capacity indicates the maximum value at operation under the following condition.

a). The cooling and heating capacities are the maximum capacities that were obtained by operating in the above air conditions and with a refrigerant pipe of about 7.5m.

b). The actual capacity characteristics vary with the combination of indoor and outdoor units. See the technical information.c). The operating noise is the data that was obtained by measuring it 1.5m from the bottom of the unit in an anechoic room.

(Noise meter A-scale value)d). The figures of Electrical characteristic of P80 and P140 models indicate at 220V and at middle external static pressure,

electrical characteristic of P200 and P250 models indicate at 440V and at high external static pressure.e). When the 100% fresh air indoor units are connected, the maximum connectable indoor units to 1 outdoor unit are as follows.

f ). Operational temp range is cooling : from 21CDB/15.5C WB to 43CDB/35CWB. Heating : from -10CDB to 20CDB

Thermo off (Fan) operation automatically starts either when temperature is lower than 21CDB in cooling mode or when the temperature exceeds 20CDB in heating mode.

g ). As the room temp is sensed by the thermo in the remote controller or the one in the room, be sure to use ether remote controller or room thermo.

h ). Dry mode is Not available. Fan mode operation during the thermo off in Cooling/Heating mode. i ). The fan would temporarily stops either with R2/WR2 system or in defrost. j ). In any case, the air flow rate should be kept lower than 110% of the above chart.Please see Fan curves for the details.k ). When this unit is used as sole A/C system, be careful about the dew in air outlet grilles in cooling mode. l ). Un-conditioned outdoor air such as humid air or cold air blows to the indoor during thermo off operation.

Please be careful when positioning indoor unit air outlet grilles, ie take the necessary precautions for cold air, and alsoinsulate rooms for dew condensation prevention as required.

m). Air filter must be installed in the air intake side.The filter should be attached where easy maintenance is possible in case of usage of field supply filters.

n ). Long life filter cannot be used with Hi-efficiency filter together.
