Before installation and electric work 
Before installing the unit, make sure you read all the “Safety 
precautions”. 
The “Safety precautions” provide very important points regarding 
safety. Make sure you follow them.

 Caution: 
Describes precautions that should be observed to prevent 
damage to the unit 
 
 
 Warning: 
Carefully read the labels affixed to the main unit. 
 
   
Warning: 
• 
The unit must be installed by an authorized Dealer or 
properly trained technician.  
− 
Improper installation by the user may result in water 
leakage, electric shock, or fire. 
• 
Install the air unit in a place that can withstand its 
weight. 
− 
Inadequate strength may cause the unit to fall down, 
resulting in injuries. 
• 
Use the specified cables for wiring. Make the 
connections securely so that the outside force of the 
cable is not applied to the terminals. 
− 
Inadequate connection and fastening may generate heat 
and cause a fire. 
• 
Prepare for typhoons, hurricanes, earthquakes etc. and 
install the unit at the specified place. 
− 
Improper installation may cause the unit to topple and result 
in injury. 
• 
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 no touch the heat exchanger fins. 
− 
Improper handling may result in injury
• 
When handling the product, always wear protective 
equipment. 
− 
EG: Gloves, full arm protection, and safety glasses.  
− 
Improper handling may result in injury. 
• 
Install the air conditioner according to this Installation 
Manual.  
− 
If the unit is installed improperly, water leakage, electric 
shock, or fire may result.  
• 
Have all electric work done by a licensed electrician 
according the “National Electrical code and local 
Electrical codes” and “Interior Wire Regulations” and 
the instructions given in this manual and always use a 
special circuit. 
− 
If the power source capacity is inadequate or electric work 
is performed improperly, electric shock and fire may result. 
• 
Keep the electric parts away from water (washing water 
etc.). 
− 
It might result in electric shock, catching fire or smoke
• 
When cleaning the Heat Exchanger and Drain Pan, 
ensure the Control Box, Motor and LEV remain dry, 
using a water proof covering. 
• 
When installing and moving the air conditioner to 
another site, do not charge it with a refrigerant different 
from the refrigerant specified 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 damaged.  
• 
When moving and reinstalling the air conditioner, 
consult the dealer or an authorized technician.  
− 
If the air conditioner is installed improperly, water 
leakage, electric shock, or fire may result. 
• 
Do not reconstruct or change the settings of the 
protections devices. 
− 
If the pressure switch, thermal switch, or other protection 
devices are shorted and operated forcibly, or parts other 
than those specified by Mitsubishi Electric are used, fire 
or explosion may result.  
• 
To dispose of this product, consult your dealer. 
• 
Do not use a leak detection additive.  
 
Precautions for devices that use R410A refrigerant. 
 
   Caution: 
• 
Do not use the existing refrigerant piping. 
− 
The old refrigerant and refrigeration 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 specified 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 contaminants. 
 
− 
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 fill 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 is used, the chlorine in the 
refrigerant 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 and cause the refrigerator oil to deteriorate. 
• 
Do not use the following tools that are used with 
conventional refrigerants. 
− 
(Gauge manifold, charge hose, gas leak detector, 
reverse flow check valve, refrigerant charge base, 
vacuum gauge, refrigerant recovery equipment). 
− 
If the conventional refrigerant and refrigeration oil are 
mixed in the R410A, the refrigerant may deteriorate. 
− 
If water is mixed in the R410A, the refrigeration oil may 
deteriorate. 
− 
Since R410A does not contain any chlorine, gas leak 
detectors for conventional refrigerant will not react to it.  
• 
Be especially careful when managing the tools. 
− 
If dust, dirt, or water gets in the refrigeration system, the 
refrigerant may deteriorate.
