1. FIRST OF ALL
• This document is an installation manual for the Daikin REYQ-P
Series VRV Inverter. Before installing the unit, read this manual
thoroughly, and following the instructions contained in it.
After installation, do a test run to make sure the unit runs properly,
and then explain how to operate and take care of the unit to the
customer, using the operation manual.
Lastly, make sure the customer keeps this manual, along with the
operation manual, in a safe place.
1-1 Safety considerations
Please read these “Safety considerations” carefully before installing
air conditioning unit and be sure to install it correctly. The safety pre-
cautions listed here are divided into two categories.
In either case, important safety information is listed which must be
read carefully.
Warning ........Failure to observe a warning may result in death
or serious injury.
Caution .........Failure to observe a caution may result in injury
or damage to the unit.
These too might lead to serious injury depend-
ing on the circumstances.
Warning
• Ask your dealer or qualified personnel to carry out installation
work. Do not try to install the machine yourself.
Improper installation may result in water leakage, electric
shocks or fire.
• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
• When installing the unit in a small room, take measures against to
keep refrigerant concentration from exceeding allowable safety
limits in the event of refrigerant leakage.
Excessive refrigerant in a closed ambient can lead to oxygen defi-
ciency. Contact your dealer for more information.
• Be sure to use only the specified accessories and parts for instal-
lation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire or the unit falling.
• Install the air conditioner on a foundation strong enough to with-
stand the weight of the unit.
A foundation of insufficient strength may result in the unit falling
and causing injuries.
• Carry out the specified installation work after taking into account
strong winds, typhoons or earthquakes.
Improper installation work may result in the unit falling and caus-
ing accidents.
• Make sure that a separate power supply circuit is provided for this
unit and that all electrical work is carried out by qualified person-
nel according to local and national regulations and this installation
manual.
An insufficient power supply capacity or improper electrical con-
struction may lead to electric shocks or fire.
• Be sure to establish an earth.
Do not earth the unit to a utility pipe, arrester or tele-
phone earth.
Incomplete earth may cause electrical shock or fire.
A high surge current from lightning or other sources may cause
damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks or fire.
• Before touching electrical parts, turn off the power.
Failure to turn off the power may result in electric shocks.
• Make sure that all wiring is secured, the specified wires are used,
and no external forces act on the terminal connections or wires.
Improper connections or installation may result in the terminals
overheating or fire.
• When wiring the power supply and connecting the remote control-
ler wiring and transmission wiring, position the wires so that the
EL.COMPO.BOX lid can be securely fastened.
Improper positioning of the EL.COMPO.BOX lid may result in
electric shocks or fire.
• If the refrigerant gas leaks during installation, ventilate the area
immediately.
Toxic gas may be produced if the refrigerant gas comes into con-
tact with fire.
• After completing the installation work, check that the refrigerant
gas does not leak.
Toxic gas may be produced if the refrigerant gas leaks into the
room and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
• Do not directly touch the refrigerant leaked from refrigerant piping
connections.
Frostbite may be caused.
• Do not allow children to mount on the outdoor unit, or avoid
placing any object on it. Falling or tumble may result in injury.
Caution
• While following the instructions in this installation manual,
install drain piping in order to ensure proper drainage and insu-
late piping in order to prevent condensation.
Improper drain piping may result in water leakage and property
damage.
• Install the indoor, BS and outdoor units, power supply wiring and
connecting wiring at least 1 meter away from televisions or radios
in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be
sufficient enough to eliminate the noise.)
