Mitsubishi Electric ECOV-X37VA Manuel D'installation page 9

Tighten terminal screws to the specified torque.
Loose screws or wire contact may cause smoke
or fire.
To reduce the risk of injury or electric shock,
turn off the main power before performing elec-
trical work.
All electric work must be performed by a quali-
fied electrician according to the local regula-
tions, standards, and the instructions detailed in
the Installation Manual. Use specified electrical
wires and a dedicated circuit. Capacity shortage
in the power supply circuit or improper installa-
tion may result in electric shock, malfunction,
smoke, or fire.
To reduce the risk of electric shock, smoke, or
fire, install an inverter circuit breaker on the
power supply to each unit.
CAUTION
To reduce the risk of current leakage, wire break-
age, smoke, or fire, keep the wiring out of con-
tact with the refrigerant pipes and other parts,
especially sharp edges.

Relocation and Repairs
WARNING
Do not alter or modify the unit. The unit must
only be moved, disassembled, or repaired by
your dealer or qualified personnel. Unauthorized
alteration, modification, or installation of the unit
by unqualified personnel may result in refriger-
ant leakage, water leakage, injury, electric
shock, or fire.
If the supply cord is damaged, it must be re-
placed by the manufacturer, its service agent, or
similarly qualified persons in order to avoid a
hazard.
CAUTION
To reduce the risk of short circuit, electric
shock, malfunctions, or fire, keep circuit boards
dust free, and do not touch them with bare hands
or tools.
To reduce the risk of refrigerant or water leak-
age, check the pipe supports and insulation for
damage during inspection or repair, and replace
or repair the ones that are found to be deteriorat-
ed.
Use properly rated breakers and fuses (earth
leakage breaker for inverter circuit, local switch
<switch + fuse>, no fuse breaker). The use of
breaker with a breaking capacity greater than the
specified capacity may cause electric shock,
malfunctions, smoke, or fire.
To reduce the risk of current leakage, overheat-
ing, smoke, or fire, use properly rated wires with
adequate current carrying capacity.
Do not let bare wires protrude from the terminal
block. Bare wires coming in contact with each
other may cause electric shock, smoke, or fire.
Proper grounding must be provided by a li-
censed electrician. Do not connect the ground-
ing wire to a gas pipe, water pipe, lightning rod,
or telephone wire. Improper grounding may re-
sult in electric shock, smoke, fire, or malfunction
due to electrical noise interference.
To reduce the risk of short circuit, electric
shock, or malfunctions, keep wire shavings out
of the terminal blocks.
To reduce the risk of short circuit, current leak-
age, electric shock, smoke, or fire, do not per-
form maintenance work in the rain.
To reduce the risk of injury, electric shock, or
fire, properly reinstall all removed components
after completing repair work.
R744 is cold. Avoid skin contact with R744.
To reduce the risk of frost burn, wear leather
gloves before touching the refrigerant hose or
the valve.
The pressure of the refrigerant system using
R744 is high. When removing R744 for mainte-
nance or other purposes from the system, fix the
refrigerant hose, and remove R744 gradually.
When removing R744 from the system, wrap the
tip of the hose with a cloth, and remove R744
gradually. Refrigerant in the dry ice state may
spew out along with a large amount of oil.
