General safety precautions
The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the electrical
component box service panel or before making any
connections or touching electrical parts.
Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of the main terminal, main circuit capacitors
or electrical parts and, before touching, be sure that those
voltages are 50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.
Also, at least, following information shall be provided at an accessible
place of the system:
Instructions for shutting down the system in case of an
emergency.
Name and address of fire department, police and hospital.
Name, address and day and night telephone numbers for
obtaining service.
In Europe, EN 378 provides the necessary guidance for this logbook.
WARNING
Ask your dealer or qualified personnel to carry out installation
work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.
Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.
When a unit is installed in a small room, it is necessary to take
measures so that the leaked refrigerant amount does not
exceed the limit even if it leaks. As for the measures to prevent
the leak from not exceeding the limit, please consult with your
distributor.
If the leaked amount exceeds the limit, it may cause an oxygen
deficiency accident.
Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.
