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.

For RZQG units only

 

For year round cooling applications with low indoor humidity 
conditions, such as Electronic Data Processing rooms, contact 
your dealer or see the engineering databook or the service 
manual.

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 15

.

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.
