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 instructions for the oper-
ator
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.
nThe existing regulations concerning accident
prevention must be adhered to.
nDo not operate units or components with
obvious defects or signs of damage.
nContact with equipment parts or components
can lead to burns or injury.
nEnsure that electrical energy does not pose a
risk.
nRegulations of the VDE and the local energy
supply company must be adhered to.
NOTICE!
Material damage due to mineral oils!
Mineral oil products permanently damage
EPDM seal elements; the sealing properties
may therefore be lost. We do not take responsi-
bility or provide warranty replacements for
damage caused by seals that are damaged in
this way.
–It is essential that you prevent EPDM from
coming into contact with mineral oil sub-
stances.
–Use a lubricant that is free of mineral oil and
has a silicone or polyalkylene basis, such
as Unisilkon L250L and Syntheso Glep 1
made by Klüber, or a silicon spray.
1.7 Safety notes for installation and
inspection tasks
nThe operator must ensure that all inspection
and installation work is carried out by author-
ised and qualified personnel who have thor-
oughly read the operating manual.
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.
nRegional regulations and laws as well as the
Water Ecology Act (WHG) must be observed.
nThe electrical power supply should be adapted
to the requirements of the units.
nThe units and components must be kept at an
adequate distance from flammable, explosive,
combustible, abrasive and dirty areas or
atmospheres.
nSafety devices may not be modified or
bypassed.
1.8 Unauthorised modification and
changes
The operational safety of the fresh water module
that was delivered is guaranteed only with
intended use in accordance with section 1.8 of the
operating instructions. Under no circumstances
should the threshold values specified in the data-
sheet be exceeded.
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 manufacturer ensure safety. The
use of other parts may invalidate liability for
resulting consequences.
1.9 Intended use
Depending on its type and design, the cooling
module as an accessory is only suitable for the
intended use on REMKO WSP heat pumps.
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 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.
1.11 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.
1.12 Transportation and
packaging
The units are shipped in sturdy transport pack-
aging or within the heat pump housing. Immedi-
ately check the units on delivery and make a note
of any damage or missing parts on the delivery
note. Inform the forwarding agent and contractual
partner. Claims under guarantee made at a later
date will not be accepted.
WARNING!
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!
1.13 Environmental protection and
recycling
Disposing 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.
Disposing of the units and their components
For the manufacture of the units and components,
only recyclable materials have been used. Help
protect the environment by ensuring that the units
or components (for example batteries) are not dis-
posed of in household waste, but only in accord-
ance with local regulations and in an environmen-
tally safe manner, e.g. using authorised disposal
and recycling specialists or council collection
points.
