3.0 Safety notes
3.1 Safety Notes – general
The following instructions refer to the standard design of
substation. Special versions of substations are available on
request.
This operating manual should be read carefully before installation
and start-up of the substation. The manufacturer accepts no
liability for damage or faults that result from non-compliance with
the operating manual. Please read and follow all the instructions
carefully to prevent accidents, injury and damage to property.
Assembly, start-up and maintenance work must be performed by
qualified and authorized personnel only.
Please comply with the instructions issued by the system
manufacturer or system operator.
Corrosion protection
All pipes and components are made of stainless steel and brass.
The maximum chloride compounds of the flow medium should not
be higher than 150 mg/l.
The risk of equipment corrosion increases considerably if the
recommended level of permissible chloride compounds is
exceeded.
Energy source
The substation is designed for district heating as the primary
source of energy. However, also other energy sources can be used
where the operating conditions allow it and always are comparable
to district heating.
Application
The substation is designed to be connected to the house
installation in a frost-free room, where the temperature does not
exceed 50 °C and the humidity does not exceed 60%. Do not cover
or wall up the substation or in any other way block the entrance
to the station.
Choice of material
Choice of materials always in compliance with local legislation.
Safety valve(s)
We recommend mounting of safety valve(s), however, always in
compliance with local regulations.
Connection
The substation must be equipped with features that ensure that
the substation can be separated from all energy sources (also
power supply).
Emergency
In case of danger or accidents - fire, leaks or other dangerous
circumstances - interrupt all energy sources to the station if
possible, and seek expert help.
In case of discoloured or bad-smelling domestic hot water, close all
shut-off valves on the substation, inform the operating personnel
and call for expert help immediately.
REACH
All Danfoss A/S products fulfill the requirements in REACH.
One of the obligations in REACH is to inform customers about
presence of Candidate list substances if any, we hereby inform
you about one substance on the candidate list: The product
contains brass parts which contains lead (CAS no: 7439-92-1) in a
concentration above 0.1% w/w.
Storage
Any storage of the substation which may be necessary prior to
installation should be in conditions which are dry and heated.
Authorized personnel only
Assembly, start-up and maintenance work must be performed by
qualified and authorized personnel only.
Please observe instructions carefully
To avoid injury to persons and damage to the device, it is absolutely
necessary to read and observe these instructions carefully.
Warning of high pressure and temperature
Be aware of the installation’s permissible system pressure and
temperature.
The maximum temperature of the flow medium in the substation is
120 °C.
The maximum operating pressure of the substation is 16 bar.
The risk of persons being injured and equipment damaged increases
considerably if the recommended permissible operating parameters
are exceeded.
The substation installation must be equipped with safety valves,
however, always in accordance with local regulations.
Warning of hot surface
The substation has got hot surfaces, which can cause skin burns.
Please be extremely cautious in close proximity to the substation.
Power failure can result in the motor valves being stuck in open
position. The surfaces of the substation can get hot, which can cause
skin burns. The ball valves on district heating supply and return should
be closed.
Warning of transport damage
Before substation installation, please make sure that the substation
has not been damaged during transport.
IMPORTANT - Tightening of connections
Due to vibrations during transport all flange connections, screw joints
and electrical clamp and screw connections must be checked and
tightened before water is added to the system. After water has been
added to the system and the system has been put into operation,
re-tighten
ALL
connections.
