INTRODUCTION
BEFORE INSTALLATION
■The system will operate as a standard indoor unit to control the
room temperature. This system does not require a specific
external controller but take below cautions into account.
■Multiple outdoor unit connections are not allowed in 1
refrigerant system.
■The automatic refrigerant charging and leak detection
function are not possible when the EKEXMCB is used.
■The manufacturer of this outdoor unit has limited
responsibility for total capacity of the system because
performance is determined by the total system. The
discharge air may fluctuate depending on selected air
handling unit and depending on the installation configuration.
■Do NOT connect the system to DIII-net devices:
This could result in malfunction or breakdown of the total
system.
INSTALLATION
■For installation of the air handling unit, refer to the air handling
unit installation manual.
■Never operate the air conditioner with the discharge pipe
thermistor (R3T), suction pipe thermistor (R2T) and pressure
sensors (S1NPH, S1NPL) removed. Such operation may burn
out the compressor.
ACCESSORIES
Obligatory accessory

NAME AND FUNCTION OF PARTS (See figure 1)
BEFORE INSTALLATION
■Refer to the installation manual of the outdoor unit for details on
refrigerant piping, additional refrigerant charging, and inter-unit
wiring.
■Precautions for R410A
■The refrigerant requires strict cautions for keeping the
system clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture)
should be prevented from getting mixed into the system.
- Tight
Read "Piping installation" on page 3 carefully and follow
these procedures correctly.
■Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the
refrigerant is in state of gas, its composition changes and the
system will not work properly).
■The connected air handling units must have heat exchangers
designed exclusively for R410A.
Cautions for selection of the evaporator (air handling unit)
See Table 1 for applicable units.
Select the evaporator (field supply) according to the technical data
and limitations mentioned below.
Lifetime of the outdoor unit, operation range or operation reliability
may be influenced if you neglect these limitations.
Table 1: Limits for outdoor unit
Depending on the heat exchanger, a connectable EKEXV (expansion
valve kit) must be selected to these limitations.
Table 2
Saturated suction temperature (SST) = 6°C, SH (superheat) = 5 K,
air temperature = 27°C DB / 19°C WB.
1The air handling unit can be connected as a standard indoor unit
to the outdoor unit. The limitations of connection are determined
by the outdoor unit.

Since design pressure is 4.0 MPa or 40 bar, pipes of larger
wall thickness may be required. Refer to paragraph
"Selection of piping material" on page 4.

NOTE ■For maximum number of indoor units, see the
outdoor unit specifications.
■Table 1 shows the possible total capacity of indoor
units when configured in a standard combination.
■If the total capacity of the connected indoor units
exceeds the capacity of the outdoor unit, cooling
and heating performance may drop when running
the indoor units.
Refer to the section on performance charac-
teristics in the Engineering Data Book for details.
■The capacity class of the air handling unit is
determined by the selection of the expansion
valve kit according to Table 2.

2Selecting the expansion valve
The corresponding expansion valve needs to be selected for
your evaporator. Select the expansion valve according to the
above limitations.
3Selecting the capacity setting adaptor (see accessories)
■The corresponding capacity setting adaptor needs to be
selected depending on the expansion valve.
■Connect the correct selected capacity setting adaptor to
X24A (A1P). (See figure 3)
For the following items, take special care during
construction and check after installation is finished
SELECTING THE INSTALLATION SITE
This is a class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to
take adequate measures.
Select an installation site where the following conditions are fulfilled
and that meets your customer's approval.
■The option boxes (expansion valve and electrical control box)
can be installed inside and outside).
■Do not install the option boxes in or on the outdoor unit.
■Do not put the option boxes in direct sunlight. Direct sunlight will
increase the temperature inside the option boxes and may
reduce its lifetime and influence its operation.
■Choose a flat and strong mounting surface.
■Keep the space in front of the boxes free for future maintenance.
■Keep evaporator (air handling unit), power supply wiring and
transmission wiring at least 1 m away from televisions and
radios. This is to prevent image interference and noise in those
electrical appliances. (Noise may be generated depending on
the conditions under which the electric wave is generated, even
if 1 m is kept.)
Precautions
Do not install or operate the unit in rooms mentioned below.
■Where mineral oil, like cutting oil is present.
■Where the air contains high levels of salt such as air near the

Piping connections
Make sure to install gas and liquid pipe diameters in function of the
air handling unit capacity class.
Selection of piping material
1. Foreign materials inside pipes (including oils for fabrication)
must be 30 mg/10 m or less.
2. Use the following material specification for refrigerant piping:
■Construction material: phosphoric acid deoxidized seamless
copper for refrigerant.
■Temper grade: use piping with temper grade in function of the
pipe diameter as listed in the table below.
■The pipe thickness of the refrigerant piping should comply
with relevant local and national regulations. The minimal pipe
thickness for R410A piping must be in accordance with the
table below.
3. In case the required pipe sizes (inch sizes) are not available, it is
also allowed to use other diameters (mm sizes), taken the
following into account:
■select the pipe size nearest to the required size.
■use the suitable adapters for the change-over from inch to
mm pipes (field supply).
Cautions for brazing
■Be sure to carry out a nitrogen blow when brazing.
Brazing without carrying out nitrogen replacement or releasing
nitrogen into the piping will create large quantities of oxidized
film on the inside of the pipes, adversely affecting valves and
compressors in the refrigerating system and preventing normal
operation.
■When brazing while inserting nitrogen into the piping, nitrogen
must be set to 0.02 MPa with a pressure-reducing valve (=just
enough so that it can be felt on the skin).
■For details, see manual of the outdoor unit.

INSTALLATION OF THERMISTORS
Refrigerant thermistors
Location of the thermistor
A correct installation of the thermistors is required to ensure a good
operation:
1. Liquid (R2T)
Install the thermistor behind the distributor on the coldest pass
of the heat exchanger (contact your heat exchanger dealer).
2. Gas (R3T)
Install the thermistor at the outlet of the heat exchanger as close
as possible to the heat exchanger.
Evaluation must be done to check if the evaporator is protected
against freeze-up.
Execute test operation and check for freeze-up.
Installation of the thermistor cable
1Put the thermistor cable in a separate protective tube.
2Always add a pull-relief to the thermistor cable to avoid strain on
the thermistor cable and loosening of the thermistor. Strain on
the thermistor cable or loosening of the thermistor may result in
bad contact and incorrect temperature measurement.
Fixation of the thermistor
1Fix the thermistor with insulating aluminum tape (field supply) in
order to ensure a good heat transference.
2Put the supplied piece of rubber around the thermistor
(R2T/R3T) in order to avoid loosening of the thermistor after
some years.
3Fasten the thermistor with 2 tie wraps.
4Insulate the thermistor with the supplied insulation sheet.
Air thermistor
The air thermistor (R1T) can be installed either in the room that
needs temperature control or in the suction area of the evaporator.
