1. FIRST OF ALL
• This document is an installation manual for the Daikin Booster
Unit. 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.
• This manual does not describe how to install the indoor unit and out-
door unit.
Refer to the installation manual included with the indoor unit and

1-1 Safety Precautions
Please read these “Safety precautions” carefully before installing the
booster unit and be sure to install it correctly.
After completing installation, conduct a trial operation to check for
faults and explain to the customer how to operate the booster unit
and take care of it with the aid of the operation manual. Ask the cus-
tomer to store the installation manual along with the operation man-
ual for future reference.
Meaning of WARNING and CAUTION notices
WARNING .....Failure to follow these instructions properly may
result in personal injury or loss of life.
CAUTION ......Failure to observe these instructions properly
may result in property damage or personal
injury, which may be serious depending on the
circumstances.
WARNING
• Ask your dealer or qualified personnel to carry out installation
work.
Do not attempt to install the booster unit yourself. Improper
installation may result in water leakage, electric shocks or fire.
• Maintenance personnel of the manufacturer or equivalent skilled
personnel should install this unit.
• Install the booster unit in accordance with the instructions in 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.
Contact the place of purchase for more information. Excessive
refrigerant in a closed ambient can lead to oxygen deficiency.
• Be sure to use only the specified accessories and parts for instal-
lation work.
Failure to use the specified parts may result in the unit falling,
water leakage, electric shocks or fire.
• Install the booster unit on a foundation strong enough to withstand
the weight of the unit.
A foundation of insufficient strength may result in the equipment
falling and causing injury.
• Carry out the specified installation work after taking into account
strong winds, typhoons or earthquakes.
Failure to do so during installation work may result in the unit fall-
ing and causing 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 laws and regulations and this installation
manual.
An insufficient power supply capacity or improper electrical con-
struction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used,
and that there is no strain on the terminal connections or wires.
Improper connections or securing of wires may result in abnormal
heat build-up or fire.
• When wiring the power supply and connecting transmission wir-
ing, position the wires so that the control box lid can be securely
fastened.
Improper positioning of the control box lid may result in electric
shocks, fire or the terminals overheating.
• If 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 installation, check for refrigerant gas leakage.
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.
• Be sure to switch off the unit before touching any electrical parts.
• Do not directly touch refrigerant that has leaked from refrigerant
pipes or other areas, as there is a danger of frostbite.
• Do not allow children to climb on the outside unit and avoid plac-
ing objects on the unit.
Injury may result if the unit becomes loose and falls.
• Be sure to earth the booster unit.
Do not earth the unit to a utility pipe, lightning conductor or
telephone earth lead. Imperfect earthing may result in
electric shocks or fire.
A high surge current from lightning or other sources may cause
damage to the booster unit.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks or fire.
CAUTION
• While following the instructions in this installation manual, install
drain piping to ensure proper drainage and insulate piping to pre-
vent condensation.
Improper drain piping may result in indoor water leakage and
property damage.
