2.0 Safety note
This section provides you with an overview of all relevant
safety aspects for optimum protection for you and your
personnel and the safe and fault-free operation of the
unit. The individual sections also contain specic, symbol-
-identied safety notes for averting immediate dangers.
General
The unit is built in accordance with the sound engineering
practise and follow all relevant EU regulations applicable at
the time of its development and production. The unit can,
however, entail dangers if it is used by unskilled or not properly
trained personnel or is used improperly or not as intended.
Every person assigned to work on or with the unit must therefore have read and understood the operating instructions before the work begins. The operator is recommended to have all
relevant personnel conrm the understanding of the operating instructions in writing.
Changes of any kind and additions to or conversions on the
unit are strictly forbidden, and all warranty and product responsibly will on longer by covered by Danfoss District Energy.
Please always agree conversion and extension work
with the manufacturer. All safety, warning and operating
notices on the unit must always be kept in an easy to
read condition. Damaged signs or stickers must be renewed immediately. Given setting values or ranges must
be observed.
Safety note
Operator/owner’s responsibility
• Always keep operating instructions close to the unit and
accessible for the installation, operating, maintenance
and cleaning personnel at all times.
• Only operate the unit within the product specied
pressure and temperature limits.
• Always keep safety devices freely accessible and check
regularly.
The information on safety at work applies to the European
Union ordinances and is applicable at the time the unit is produced. The operator is obliged to determine the compliance
of the safety at work rules and regulations and must observe
and updated if new regulations is adopted by the EU during
the entire time of the unit’s life time.
Outside the EU the applicable safety at work legislation and
regional provisions and regulations must be complied. In addition to the safety at work, notes in these operating instructions,
and the generally applicable safety, accident-prevention and
environmental protection regulations must be observed and
complied with for the specic area of application.
The operator and the authorised personnel are responsible for the fault-free operation of the unit, and for the
clear denition of responsibilities with the unit’s installation, operation, maintenance and cleaning. The information
provided in the operating instructions must be followed
in full and unrestricted!
The operator must also ensure that:
- All residual risk that arises as a result from the point of
installation must be determined and minimized.

Proper use
The unit’s functional and operational safety is only guaranteed
when used properly in accordance with the information in
this instruction.
Proper use also includes correct compliance with installation,
operating, maintenance and cleaning instructions.
Any other use of the unit is forbidden and applies as improper!
Safety at work
Adhering to the notes on safety at work dangers to people
and/or the system must be prevented. Ignoring or non-
-compliance with these notes can cause dangers to people and property from mechanical eects or the failure
of the system and the entire workplace. Non-compliance
with safety regulations will result in the loss of all rights no
claims to damages.
Personal protection equipment

agents for damages caused by improper use of the unit
shall be excluded. The operator and/or owner alone are
the sole responsible party for all damages caused by
improper use.
Safety note
• Protective gloves for protecting the hands against
abrasion, grazes, or deeper injuries and against contact
with hot surfaces.
• Protective glasses for protecting the eyes against
ejecting parts and hot liquid splashes.
• Safety shoes for protecting against falling parts and
slipping on slippery surfaces.

2.1 Residual risk
The unit has undergone a risk analysis as required by the
Machinery directive and is preformed according to En14121.
The unit design complies with the current state of technology. Nonetheless there are residual risks! The unit generates
a strong liquid jet when opening the draining or venting components, for example.
Possible harm caused by liquid squirting
under high pressure.
Wear personal protection equipment
with all work on the unit.
The unit works with high voltages 230/240
Vac 50Hz and a maximum current on 6 A.
Possible Harm caused by electrical current!
The electrical forces can cause fatal injuries.
Damage on insulation or individual components
can endanger life.
– Switch main switch o (1F1) or disconnect supply,
before maintenance, cleaning or repair work and
secure or monitor against accidental or unintended
reengagement of the power supply.
– Do not remove any safety components or put
them out of service.
Residual risks
The unit weighs app. 40 – 45 kg.
Possible harm! Danger of crushing.
Heavy weights can cause crushing dangers when
transporting, including with lifting gear.
The unit can have sharp edges and corners.
Possible harm! Sharp-edged mounting plate and
brackets and pointed corners can cause cuts.
Wear protective gloves when working on the unit!
Possible harm! Danger of burns.
Hot surfaces can cause serious burn injuries. Wear

This standard shall be observed when new technical literature or changes are designed
for DH products. The standard is valid throughout DH.
The standard shall describe the rules for implementing disposal instructions in technical
DH literature (Data sheet, Instruction, etc.).
In spite of, that none of the electronic and electro-mechanical DH-products are within
the scope of WEEE, it has been decided to put a relevant standard text and a bin-symbol
in the technical literature for these products (see clause 5).
The text and the bin-symbol do not relate to the WEEE, but emphasizes that Danfoss is
an environmental friendly company. Please notice that bin symbol with registration
number, below the bin, should not be used.
There are no legal requirements to have disposal instructions included in technical DH
literature like data sheets or instructions for non electronic and non electro-mechanical
products. Nevertheless we foresee that there will be requirements in the future.
In order to prepare ourselves we therefore have decided to add a general disposal in-
struction also in this product group (see clause 5).
Following general text in connection with the waste bin shall be implemented in all
technical literature for DH products:
3.0 Storage and handling
If the substation is stored before installation, make sure
that the place is dry and heated. (Humidity max. 60 % and
storage temperature 5 – 70 °C).
Do not stack the unit higher than factory shipped.
Units that are shipped in cardboard packaging are to
be lifted by the carrying handles of the packaging.
Transport/removals over great distances should be carried
out on pallets.
During and after unpacking, the substation can be lifted by
using straps, tted around the pipes or it can be lifted by hand
in the pipes. Lifting in the pipes can cause leaks. ALWAYS retighten.
4.0 Disposal
HANDLING
When working on the substation suitable
safety shoes must be worn.
Storage and handling / disposal
Disposal instruction:
This product should be dismantled and its components
sorted, if possible, in various groups before recycling or disposal.
Always follow the local disposal regulations.
