SAFETY

 

PRECAUTIONS

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 and in accordance with the applicable legislation.

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 and optional
equipment 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.

DANGER

Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.

WARNING

INFORMATION

This symbol identifies useful tips or additional information.

Electric current.

Danger of burning and scalding.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switch 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 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.
