Safety considerations
The precautions here, all cover very important topics, so be sure to
follow them carefully.
All activities described in this manual shall be carried out by an
installer.
Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses, …) when performing installation,
maintenance or service to the unit.
If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.
Improper installation or attachment of equipment or accessories
could result in electric shock, short-circuit, leaks, fire or other damage
to the equipment. Be sure only to use accessories, optional
equipment and spare parts made by Daikin which are specially
designed for use with the products as of subject in this manual and
have them installed by an installer.
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.
The equipment is not intended for use in a potentially explosive
atmosphere.
Consult your local dealer regarding what to do in case of
refrigerant leakage. When the unit is to be installed in a small
room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.
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.
Install the unit on a foundation that can withstand its weight.
Insufficient strength may result in the fall of equipment and
causing injury.
Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.
Make sure that all electrical work is carried out by qualified
personnel according to the applicable legislation and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheating of the terminals,
electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
When planning to relocate former installed units, you must first
recover the refrigerant after the pump down operation. Refer to
chapter
"13. Pump down operation" on page 12
.
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
Be sure to install an earth leakage circuit breaker in accordance
with applicable legislation. Failure to do so may cause electrical
shock and fire.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.
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 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.
