English

Place such as machinery plant and chemical plant
where gas, which contains noxious gas or corrosive
components of materials such as acid, alkali organic sol-
vent and paint, is generated. Place where combustible
gas leakage is likely.
Copper piping and brazed joints may corrode, causing
refrigerant to leak or poisoning and fire due to leaked
gas.

d. Place such as bathroom subjected to moisture.

Electric leak or electric shocks and other failure can be
caused.

e. Locations below freezing point.

Using the unit at temperatures below 0°C may cause the
drain pan the supply and discharge piping, the humidify-
ing element, the solenoid valves, and other parts to
freeze, which can cause accidents.

Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the
control system and result in a malfunction of the equip-
ment.

•

Make sure the temperature and humidity near the unit and
the air suction/discharge air grille is within limit dictated by
the usage conditions.
Do not install in refrigerated truck or other locations with low
temperatures or near heated pools.
This may cause fires or short circuits.

•

Make sure that a snow protection measure is taken. If no pro-
tection snow may enter through the outdoor ducts, and cause
damaging furniture and electric shock and fire.

BEFORE INSTALLATION

The accessories needed for installation must be retained in
your custody until the installation work is completed. Do
not discard them!

After carrying in the unit, protect it with packing materials to pre-
vent it from scratching until installation work is done.

[1] Decide upon a line of transport.

[2] Leave the unit inside its packaging while moving, until reach-

ing the installation site. Where unpacking is unavoidable,
use a sling of soft material or protective plates together with
a rope when lifting, to avoid damage or scratches to the unit.

Hold the unit by the hanger brackets (4) when opening the
crate and moving it, and do not lift it holding on to any other
part (especially the refrigerant piping, the drain piping, the
water supply piping, and the duct connecting flange).

•

Be sure to check the type of R410A refrigerant to be used
before installing the unit. (Using an incorrect refrigerant will
prevent normal operation of the unit.)

•

For the installation of an outdoor unit, refer to the installa-
tion manual attached to the outdoor unit.

2. 1 PRECAUTIONS

•

Be sure to instruct customers how to properly operate the
unit (especially maintenance of air filter, and operation proce-
dure) by having them carry out operations themselves while
looking at the manual.

•

Where the air contains high levels of salt such as that near
the ocean and where voltage fluctuates greatly such as that
in factories. Also in vehicles or vessels.

2. 2 ACCESSORIES

Check the following accessories are included with your unit.

2. 3 OPTIONAL ACCESSORIES

•

This unit can be made a part of two different systems: as part
of the combined operation system used together with VRV

SYSTEM Air Conditioners, and as the independent system
using only the HRV. An operating remote controller is
required for this unit when using the unit as an independent
system.
Select a suitable remote controller from below table accord-
ing to customer request and technical materials.

Table

NOTE) 1
If you use the remote controller which is not listed in above
table, please consult your dealer.
NOTE) 2
We recommend the remote controller “BRC1D527” espe-
cially when the unit is used as independent system. Because
it displays the ventilation mode and can be selected ventila-
tion fan mode with the button.

•

When installing the unit, have ready the round shape hood,
the air discharge grille and the air suction grille, and other
parts needed for the installation.
Consult your Daikin dealer when selecting optional accesso-
ries.
