1 Safety and
usage instructions
1.1 General safety notes
Carefully read the operating manual before com-
missioning the units for the first time. It contains
useful tips and notes such as hazard warnings to
prevent personal injury and material damage.
Failure to follow the directions in this manual not
only presents a danger to people, the environment
and the system itself, but will void any claims for
liability.
Keep this operating manual and the refrigerant
data sheet near to the units.
1.2 Identification of notes
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by sym-
bols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.
DANGER!
Contact with live parts poses an immediate
danger of death due to electric shock. Damage
to the insulation or individual components may
pose a danger of death.
DANGER!
This combination of symbol and signal word
warns of a situation in which there is immediate
danger, which if not avoided may be fatal or
cause serious injury.
WARNING!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may be fatal or cause
serious injury.
CAUTION!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may cause injury or mate-
rial and environmental damage.
NOTICE!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may cause material and
environmental damage.
This symbol highlights useful tips and recom-
mendations as well as information for efficient
and fault-free operation.
1.3 Personnel qualifications
Personnel responsible for commissioning, opera-
tion, maintenance, inspection and installation must
be able to demonstrate that they hold a qualifica-
tion which proves their ability to undertake the
work.
1.4 Dangers of failure to observe
the safety notes
Failure to observe the safety notes may pose a risk
to people, the environment and the units. Failure to
observe the safety notes may void any claims for
damages.
In particular, failure to observe the safety notes
may pose the following risks:
nThe failure of important unit functions.
nThe failure of prescribed methods of mainte-
nance and repair.
nDanger to people on account of electrical and
mechanical effects.
1.5 Safety-conscious working
The safety notes contained in this manual, the
existing national regulations concerning accident
prevention as well as any internal company
working, operating and safety regulations must be
observed.

1.6 Safety notes for the operator
The operational safety of the units and compo-
nents is only assured providing they are used as
intended and in a fully assembled state.
nThe units and components may only be set up,
installed and maintained by qualified per-
sonnel.
nProtective covers (grille) over moving parts
must not be removed from units that are in
operation.
nDo not operate units or components with
obvious defects or signs of damage.
nContact with certain unit parts or components
may lead to burns or injury.
nThe units and components must not be
exposed to any mechanical load, extreme
levels of humidity or extreme temperature.
nSpaces in which refrigerant can leak sufficient
to load and vent. Otherwise there is danger of
suffocation.
nAll housing parts and device openings, e.g. air
inlets and outlets, must be free from foreign
objects, fluids or gases.
nThe units must be inspected by a service tech-
nician at least once annually. Visual inspec-
tions and cleaning may be performed by the
operator when the units are disconnected from
the mains.
1.7 Safety notes for installation,
maintenance and inspection
nAppropriate hazard prevention measures must
be taken to prevent risks to people when per-
forming installation, repair, maintenance or
cleaning work on the units.
nThe setup, connection and operation of the
units and its components must be undertaken
in accordance with the usage and operating
conditions stipulated in this manual and comply
with all applicable regional regulations.
nLocal regulations and laws such as Water
Ecology Act must be observed.
nThe power supply should be adapted to the
requirements of the units.
nUnits may only be mounted at the points pro-
vided for this purpose at the factory. The units
may only be secured or mounted on stable
structures, walls or floors.
nMobile units must be set up securely on suit-
able surfaces and in an upright position. Sta-
tionary units must be permanently installed for
operation.
nThe units and components should not be oper-
ated in areas where there is a heightened risk
of damage. Observe the minimum clearances.
nThe units and components must be kept at an
adequate distance from flammable, explosive,
combustible, abrasive and dirty areas or
atmospheres.
nSafety devices must not be altered or
bypassed.
1.8 Unauthorised modification
and changes
Modifications or changes to units and components
are not permitted and may cause malfunctions.
Safety devices may not be modified or bypassed.
Original replacement parts and accessories
authorised by the manufactured ensure safety. The
use of other parts may invalidate liability for
resulting consequences.
1.9 Intended use
Depending on the model and the unit, the units are
only intended to be used as a chiller for the cooling
or warming of the operating medium water or a
water-glycol mixture within a closed medium cycle.
Any different or additional use is a non-intended
use. The manufacturer / supplier assumes no lia-
bility for damages arising from non-intended use.
The user bears the sole risk in such cases.
Intended use also includes working in accordance
with the operating and installation instructions and
complying with the maintenance requirements.
The threshold values specified in the technical
data must not be exceeded.
1.10 Warranty
For warranty claims to be considered, it is essential
that the ordering party or its representative com-
plete and return the "certificate of warranty" to
REMKO GmbH & Co. KG at the time when the
units are purchased and commissioned.
The warranty conditions are detailed in the "Gen-
eral business and delivery conditions". Further-
more, only the parties to a contract can conclude
special agreements beyond these conditions. In
this case, contact your contractual partner in the
first instance.

1.11 Transport and packaging
The devices are supplied in a sturdy shipping con-
tainer. Please check the equipment immediately
upon delivery and note any damage or missing
parts on the delivery and inform the shipper and
your contractual partner. For later complaints can
not be guaranteed.

Plastic films and bags etc. are dangerous
toys for children!
Why:
- Leave packaging material are not around.
- Packaging material may not be accessible to
children!
1.12 Environmental protection
and recycling
Disposal of packaging
All products are packed for transport in environ-
mentally friendly materials. Make a valuable contri-
bution to reducing waste and sustaining raw mate-
rials. Only dispose of packaging at approved
collection points.
Disposal of equipment and components
Only recyclable materials are used in the manufac-
ture of the devices and components. Help protect
the environment by ensuring that the devices or
components (for example batteries) are not dis-
posed in household waste, but only in accordance
with local regulations and in an environmentally
safe manner, e.g. using certified firms and recy-
cling specialists or at collection points.
