The unit must be periodically inspected by a
dealer or qualified personnel. If dust or dirt
accumulates inside the unit, the drain pipes
may become clogged, and water leakage
from the pipes may wet the surroundings
and generate odours.

Transportation and Installation
Lift the unit by placing the slings at desig-
nated locations. Support the outdoor unit
securely at four points to keep it from slip-
ping and sliding. If the unit is not properly
supported, it may fall and cause personal
injury.
To reduce the risk of injury, do not lift the
unit with the PP bands that are used on
some products.

Installation
To reduce the risk of injury, properly dis-
pose of the packing materials.
Properly dispose of the packing materials.
Tear up the packing materials that potential-
ly pose suffocation hazards.
Remove packing materials from the unit be-
fore operating the unit. Note that some ac-
cessories may be taped to the unit. Properly
install all accessories that are required. Fail-
ing to remove the packing materials or fail-
ing to install required accessories may
result in refrigerant leakage, oxygen starva-
tion, smoke, or fire.
To reduce the risk of current leakage, elec-
tric shock, or damage to the unit, seal all
openings around pipes and wires to keep
out small animals, rainwater, or snow.
Units are heavy and pose a risk of injury.
Use caution not to get your fingers or hands
caught when disassembling or reassem-
bling units.
To reduce the risk of injury, observe the re-
strictions on the maximum weight that a
person can lift.
Consult your dealer and take appropriate
measures to safeguard against refrigerant
leakage and resultant oxygen starvation. An
installation of a refrigerant gas detector is
recommended.
Any additional parts must be installed by a
dealer or qualified personnel. To reduce the
risk of water leakage, electric shock, or fire,
only use the parts specified by Mitsubishi
Electric.
Drain piping must be installed by a dealer or
qualified personnel to ensure proper drain-
age. Improper drain piping may cause water
leakage, resulting in damage to furniture
and other surroundings.
