Safety Precautions
Read before installation and performing electrical work
Thoroughly read the following safety precautions prior to installation.
Observe these safety precautions for your safety.
This equipment may have adverse effects on the equipment on the same power supply system.
Contact the local power authority before connecting to the system.
Symbol explanations
WARNING
This symbol indicates that failure to follow the instructions exactly as stated poses the risk of serious injury or death.
CAUTION
This symbol indicates that failure to follow the instructions exactly as stated poses the risk of serious injury or dam-
age to the unit.
Indicates an action that must be avoided.
Indicates important instructions.
Indicates a parts that requires grounding.
Indicates that caution must be taken with rotating parts. (This symbol is on the main unit label.) <Color: Yellow>
Indicates that the parts that are marked with this symbol pose a risk of electric shock. (This symbol is on the main
unit label.) <Color: Yellow>
WARNING
Carefully read the labels affixed to the main unit.
WARNING
Ask your dealer or a qualified technician to install the unit.
Do not make any modifications or alterations to the unit.
Consult your dealer for repair.
Improper installation by the user may result in water leak-
age, electric shock, or fire.
Improper repair may result in water leakage, electric shock,
or fire.
Properly install the unit on a surface that can withstand its
weight.
Do not touch the heat exchanger fins with bare hands.
Unit installed on an unstable surface may fall and cause in-
jury.
The fins are sharp and pose a risk of cuts.
In the event of a refrigerant leak, thoroughly ventilate the
room.
Only use specified cables. Securely connect each cable so
that the terminals do not carry the weight of the cable.
If gaseous refrigerant leaks out and comes in contact with
an open flame, toxic gases will be generated.
Improperly connected cables may produce heat and start a
fire.
Properly install the unit according to the instructions in the
Installation Manual.
Take appropriate safety measures against wind gusts and
earthquakes to prevent the unit from toppling over.
Improper installation may result in water leakage, electric
shock, or fire.
Improper installation may cause the unit to topple over and
cause injury or damage to the unit.
Have all electrical work performed by an authorized electri-
cian according to the local regulations and the instructions
in this manual. Use a dedicated circuit.
Only use accessories (i.e., air cleaners, humidifiers, electric
heaters) recommended by Mitsubishi Electric.
Insufficient power supply capacity or improper installation
of the unit may result in malfunctions of the unit, electric
shock, or fire.
i
WARNING
Keep electrical parts away from water.
Consult your dealer or a qualified technician when moving
or reinstalling the unit.
Wet electrical parts pose a risk of electric shock, smoke, or
fire.
Improper installation may result in water leakage, electric
shock, or fire.
Securely attach the control box cover.
After completing the service work, check for a refrigerant
leak.
If the cover is not installed properly, dust or water may infil-
trate and pose a risk of electric shock, smoke, or fire.
If leaked refrigerant is exposed to a heat source, such as a
fan heater, stove, or electric grill, toxic gases will be gener-
ated.
Only use the type of refrigerant that is indicated on the unit
when installing or relocating the unit.
Infiltration of any other types of refrigerant or air into the unit
may adversely affect the refrigerant cycle and may cause
the pipes to burst or explode.
Do not try to defeat the safety features of the unit.
Forced operation of the pressure switch or the temperature
switch by defeating the safety features for these devices, or
the use of accessories other than the ones that are recom-
mended by Mitsubishi Electric may result in smoke, fire, or
explosion.
When installing the unit in a small space, take appropriate
precautions to prevent leaked refrigerant from reaching the
limiting concentration.
Leaked refrigerant gas will displace oxygen and may cause
oxygen starvation. Consult your dealer before installing the
unit.
Consult your dealer for proper disposal method.
Do not use a leak detection additive.
Precautions for handling units for use with R410A
CAUTION
Do not use the existing refrigerant piping.
Only use R410A.
A large amount of chlorine that may be contained in the re-
sidual refrigerant and refrigerator oil in the existing piping
may cause the refrigerator oil in the new unit to deteriorate.
The use of other types of refrigerant that contain chloride
may cause the refrigerator oil to deteriorate.
Use a vacuum pump with a check valve.
Use refrigerant piping materials made of phosphorus deox-
idized 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.
If a vacuum pump that is not equipped with a check valve is
used, the vacuum pump oil may flow into the refrigerant cy-
cle and cause the refrigerator oil to deteriorate.
Contaminants in the refrigerant piping may cause the refrig-
erator oil to deteriorate.
Prepare tools for exclusive use with R 410A. Do not use the
following tools if they have been used with the conventional
refrigerant: gauge manifold, charging hose, gas leak detec-
tor, check valve, refrigerant charge base, vacuum gauge,
and refrigerant recovery equipment.
Store the piping materials indoors, and keep both ends of
the pipes sealed until immediately before brazing. (Keep el-
bows and other joints wrapped in plastic.)
If the refrigerant or the refrigerator oil that may be left on these
tools are mixed in with R410A, it may cause the refrigerator oil
in the new system to deteriorate.
Infiltration of water may cause the refrigerator oil to deteriorate.
Leak detectors for conventional refrigerants will not detect an
R410A leak because R410A is free of chlorine.
Infiltration of dust, dirt, or water into the refrigerant system
may cause the refrigerator oil to deteriorate or cause the
compressor to malfunction.
Use a small amount of ester oil, ether oil, or alkyl benzene
to coat flares and flanges.
Do not use a charging cylinder.
Infiltration of a large amount of mineral oil may cause the re-
frigerator oil to deteriorate.
If a charging cylinder is used, the composition of the refrigerant
in the cylinder will change and become unsuitable for use.
Charge the system with refrigerant in the liquid phase.
Exercise special care when handling tools for use with R410A.
Infiltration of dust, dirt, or water into the refrigerant system
may cause the refrigerator oil to deteriorate.
If gaseous refrigerant is drawn out of the cylinder first, the
composition of the remaining refrigerant in the cylinder will
change and become unsuitable for use.
