3 Classification of the condensing units and of its
components according to the EU directives
The condensing units are intended for incorporation
into machines in accordance with the EU Machinery
Directive 2006/42/EC. The electrical components com-
ply with the EU Low Voltage Directive 2014/35/EU. For
the incorporated pressurised components, the EU
Pressure Equipment Directive 2014/68/EU (PED) may
be applicable, except for the compressors (see below).
The corresponding declarations of conformity and man-
ufacturers’ declarations are available. Classification of
the individual components and additional explanations
see table 1, page 5.
Information
Condensing units are not considered a “func-
tional whole” according to the PED and do
therefore not fall within the scope of Art.1 §
2.1.5 “Assemblies”. The directive is therefore
only applied to the individual components. The
same applies to the CE marking. Assessment
by a notified body: Bureau Veritas, Paris –
"Technical Appraisal" for ASERCOM members
PED-TA_ASE_001_01-DEU.
Information
According to Article 4 § 3.10, semi-hermetic and
open drive compressors are excluded from the
application range of the PED. This exception is
confirmed by the evaluation of a notified body.
Please refer to "Explanations about the product
conformity" AC-100 for further explanations.
Please refer to AC-100 for the classification of
pressurised accessories for compressors.

WARNING
Risk of bursting due to counterfeit refrigerants!
Serious injuries are possible!
Purchase refrigerants only from reputable man-
ufacturers and reliable distributors!
5.1 Maximum allowable pressure
The whole system must be designed and operated
such that the maximum allowable pressure (PS) cannot
be exceeded in any part of the system (see name plate
details).
Pressure relief valves on receivers (pressure vessels)
are absolutely necessary if:
• it is to be expected that the maximum allowable
pressure will be exceeded due to external heat
sources (e.g. fire).
• the entire refrigerant charge of the system is more
than 90% of the pressure vessel volume at 20°C (ca-
pacity). The vessel volume is defined as the volume
between the valves upstream and downstream of a
pressure vessel lockable during normal operation.
• the entire refrigerant charge of the system is more
than 90% of the pressure vessel volume at 20°C (ca-
pacity). The vessel volume is defined as the volume
between the valves upstream and downstream of a
pressure vessel lockable during normal operation.
• a check valve is located between condenser and re-
ceiver.
Safety switching devices
According to local regulations, additional pressure-limit-
ing safety devices must be provided.

6 Mounting
6.1 Transporting the condensing unit
Fix either screw-in eyes or rails with screws on the four
load suspension points. The screw-in eyes and screws
must not exceed a maximum screw-in thread length of
30mm because otherwise the condenser may become
damaged! Screw-in eyes, screws and rails are not in-
cluded in the scope of delivery.
Lift the condensing unit either by means of the lifting
slings by crane or forklift or by hand directly on the
rails.

Fig.3: Transport rail
Fig.4: Lifting on lifting slings by forklift or crane
M8x30 (max.)
Fig.5: Lifting on transport rail by hand
6.1.1 Transport locks for condensing units
To avoid transport damage to condensing units in their
state of delivery, the vibration dampers of the com-
pressors are blocked by transport locks. It is absolutely
necessary to remove or loosen these locks after mount-
ing. For this, see the operating instructions of the com-
pressor KB-104.
6.2 Installing the condensing unit
The place of installation must have sufficient load-car-
rying capacity and must be level and vibration-resistant.
The minimum distances to fixed delimiting surfaces
must be complied with. Avoid a short-circuit of the air
flow or obstacles in the air flow of the condenser fans!
During the system design, take the minimum and max-
imum load into account. Execute the pipe works and
rising lines according to the generally known rules for
compound systems. Contact BITZER if the system is

KB-206-110
operated under extreme conditions (e.g. aggressive at-
mosphere, low outdoor temperatures, etc.).
Ensure good accessibility for maintenance and service
work!
If the ECOLITE condensing unit is mounted on mount-
ing brackets, the installation surface under the four fix-
ing points must be at least 6 x 6 cm. Use three mount-
ing brackets (on the right, in the middle and on the left).
It is not necessary to screw the bracket in the middle to
the device.
!
!
NOTICE
When installing the condensing unit in areas
where extreme wind loads may occur, screw it
always firmly to the ground!
If installed on a roof, provide sufficient lightning
protection!
CAUTION
The fins of the condenser have sharp edges!
Risk of lacerations.
Before performing any work on the condensing
unit: Wear protective gloves.

KB-206-1 11
6.3 Pipelines
The pipelines must be as short as possible in order to
minimise pressure drops and to keep the refrigerant
quantity available in the pipeline system as low as pos-
sible.
!
!
NOTICE
During soldering work on the suction gas line,
protect the low pressure transmitter against ex-
cess heat (max. 120°C)!
6.4 Incorporation of the condensing unit into the
refrigeration system
If the ECOLITE condensing unit is positioned above the
evaporator, the suction gas line must be executed ac-
cordingly. In case of a long suction gas line or several
evaporators, the use of the optionally available oil sep-
arator and OLC is recommended.
When using an LHL5E with only one capacity-con-
trolled cylinder bank, the suction gas line must be ex-
ecuted such that the oil return is guaranteed even at a
minimum capacity of 50%.
If the ECOLITE condensing unit is positioned below the
evaporator, an additional subcooler should be provided
(example see figure 9, page 11).

Off = no fault active
8.1.3 First switching on of the power supply
After switching on the power supply, the controller car-
ries out an automatic self-test. In doing so, the display
flashes.
Ex factory the operation of the controller in a newly de-
livered ECOLITE condensing unit is not enabled and,
for this reason, the display should show the status
“OFF” after having switched on the supply voltage.
After parametrisation of the controller, the enable can
take place by means of the parameter OnOF (F4⇒in-
it⇒OnOF) if the commissioning of the refrigerant circuit
allows it.
The condensing unit can also be enabled by means of
an external signal (potential-free relay contact). For
this, a digital input of the controller has to be configured
for the external enable of the condensing unit. This
function is not activated ex factory.
