Check that there is enough space around the unit. Consult the corresponding chapter of the Technical Catalogue for
information on the unit measurements.
Before starting installation, plan the direction of the pipes and wiring required. Also bear in mind that there must be
enough space around the unit for installation and maintenance.
Check that the ceiling surface where the unit is to be installed is completely horizontal.
Installation
Avoid obstacles that could block the air inlet or outlet ow.
Choose a position in which the unit does not take in outdoor air mixed with combustion or exhaust fumes.
The unit must not be covered in snow.
Do not use the unit in the winter when the weather conditions may lead to the formation of condensation in the heat
exchanger.
Saturation curve
? NOTE
• The formation of condensation arises if the line connecting the outdoor
and indoor temperature points and the conditions of humidity cross the
saturation curve in the psychrometric chart.
• Raising the temperature at point A (outdoor air) to point A’ gives improved
conditions in which the line connecting the outdoor and indoor temperature
points and the conditions of humidity do not cross the saturation curve. In
this case, the total heat exchanger can be used.
Dry bulb (ºC)
The limit for ambient conditions in which the total heat exchanger is used is shown in the table below as an example, at
an outdoor air temperature of 0ºC, -5ºC and -10ºC and an indoor air temperature of 30ºC. Where the indoor or outdoor
air humidity is higher, condensation may accumulate and ow outside the unit.
Absolute humidity (kg/kg)
The method for raising the temperature of A (outdoor temperature) must be determined according to current law in the
place where the unit is installed.

Lift the unit carefully.
For KPI-(502-1002)X4E
The unit should be installed so that one side of the unit is slightly 1º for KPI-(502-1002)X4E lower than the other side, in
order to avoid the incorrect position of the drain discharge.
Apply a thread-locking product to the bolts and nuts to prevent them from loosening. Otherwise, abnormal noise may be
caused by mechanical vibrations and the indoor unit may become loose.
Apply protective paint to the bolts and nuts to prevent rusting.

Check that there is no dust, sawdust or other foreign particles inside the ducts before connecting them.
! CAUTION
When connecting the ducts, do not touch the damper plate located behind the main unit.
Position and secure the ducts in the connection hoses and apply aluminium tape (eld-supplied) around the connection
to avoid air leaks. The duct connection hoses have a previously installed sealing system.
Suspend the ducts from the ceiling so that the weight does not rest on the unit.
Cover the two outdoor ducts with suitable heat insulation material to prevent the formation of condensation.
Secure the exible air duct to the outsides of the hoses supplied with the unit.

2.12.2 Unit installation
• The installation of a specic remote controller is necessary during the installation commissioning. Once the
installation commissioning is nished, this remote controller can be removed if the pin 7 is switched to ON position. In
this case, pay attention to all the setting details related with the remote controller because after remove it, they cannot
be changed.
• Do not install the DX-Interface where electromagnetic wave is directly radiated to the control box or expansion valve
box.
• Install a noise lter when noise is emitted from power supply.
• Do not install the DX-Interface where generation, owing, staying or leakage of ammable gas may occur.
• When the false ceiling contains high humidity, dew condensation water may occur on the outer surface of the
expansion valve box. Therefore utilize the insulation on the outer surface of the expansion valve box.
Installation location
1 Installation methods are selectable according to the dimension of the false ceiling.
2 Keep the distance between the unit or device with heat exchanger and the expansion valve box for the piping length
up to 5m. Also the elevation difference between the unit or device with heat exchanger and the expansion valve box
must be no more than 2m.
3 Check the ceiling slab is strong enough. If the ceiling slab is too weak to support the weight of the expansion valve
box, noise and vibration may occur.

6 Do not install the DX-Interface in a kitchen where vapour or mist ows. Dew condensation water may occur on the
expansion valve box while cooling operation. In this case, use the insulation.
7 Do not install the DX-Interface in a organic solvent (thinner or benzine) environment. Synthetic resin parts may
dissolve.
8 Do not install the DX-Interface where generation, owing or staying of ammable gas may occur.
9 The sound of refrigerant running through from the expansion valve box may be heard. Therefore install the expansion

Remarks for OACI-160K2, OACI-232 and OACI-232E
The standard maximum air volume of fresh air intake when using the outdoor air inlet duct references OACI-160K2 or
OACI-232 or OACI-232E combined with a total heat exchanger or the duct fan, is within 20% of the rated air volume
of the indoor unit (at “HIGH” mode). If the amount of incoming outdoor air exceeds this value, condensation may be
produced on the inner surface of the drain pan (air inlet hole) and, in some cases, dew may form.
In the case without total heat exchanger, use the fresh air intake kit within the range which dewing does not occur at this
kit, duct and inside the indoor unit.
With or without the total heat exchanger, follow the countermeasure according to the temperature difference between the
supply air from the room air and the outside air as shown in the table below.
Temperature difference between supply air from room air
and outside air
Below 10 deg. No countermeasure required
Below 15 deg. Perform insulation

The air through the duct does not pass through the air lter of the indoor units. Fit an air lter (Field supplied) to the
suction side of the outdoor air inlet duct in a position that allows for easy maintenance operations.
Insulate the duct and its connection using reproof insulating materials only.
? NOTE
The parts shown in the above gure will be eld-supplied.
Install an inspection panel -6- below the duct fan so that maintenance operations can be carried out on the air lter and
the damper.
Always use a damper and adjust the amount of air where a fan with a supply volume higher than the outdoor air inlet
volume limit is used.

If there are obstacles such as partitions inside the room that prevent the air from circulating correctly, branches can be
installed to provide an even air temperature.
Suitable return air grilles must be installed in line with the volume of return air. If air conditioning is provided in an
adjoining room, always install a return grille.

Fit enough insulation to the connection between the pipe and the main body of the indoor unit and to the connection
between the duct and the pipe.
Use a set of three-way outlet parts (optional parts) and completely block the air outlet on the branched duct side of the
panel (to avoid condensation and direct the air towards the branched duct).
Model Units Remarks
PI-160LS1 RCI-(1.0-6.0)FSN4 To connect to the panel outlet
The quantity of air from the branched duct side is shown in the table below as the air quantity index of the unit. If two
branched ducts are connected to the unit, the amount of air from the branched duct side will be greater and the speed of
the air on the 3-way outlet side will decrease. Therefore, the hot air projection distance will be reduced.
1 Where the branch duct is installed from this viewpoint, apply the
dimensions indicated in the gure below to avoid accidents.
2 Use ducts with non-combustible insulating materials.
3 Fit enough heat insulation to the duct to avoid condensation.
4 Follow the regulations in force regarding this matter in the place of
