2. SAFETY NOTES

2.1 Safety Notes — general
The following instructions refer to the standard design of flat stations.
It is not allowed to work with any kind of tool on the composite block — however only
when working HTC and circulation set — for mounting these.
This operating manual should be read carefully before installation and start-up of the
flat station. 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 au-
thorized 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 flat station is designed to be connected to decentralized heating installations with
various energy sources, such as district heating, central boiler (gas, oil, biomass, etc.),
solar, heat pump or a combination between them if the operating conditions allow it.
Application.
The flat station 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
80 %. Do not cover or wall up the flat station 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.
Noise level. ≤ 29,8 dB
Connection.
The flat station must be equipped with features that ensure that the flat station 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 flat station, inform the operating personnel and call for expert help immediately.
Storage.
Any storage of the flat station which may be necessary prior to installation should be in
conditions which are dry and heated.
Reach.
All products of the EvoFlat series comply with the provisions of the REACH regulation.
We are therefore obliged to inform our customers about the presence of substances ac-
cording to the SVHC candidate list, if they are present. We hereby inform you: This product
contains brass parts containing lead (CAS 7439-92-1) in a concentration above 1% (w/w).
Potential equalization / grounding.
Equipotential bonding is understood as all measures for eliminating electrical potential
differences (contact voltages), which can occur between eg two pipelines. Equipotential
bonding is an important measure for protection against electric shock. Equipotential
bonding reduces corrosion in the heat exchanger, instantaneous water heaters, district
heating stations and plumbing installations. Equipotential bonding should be in ac-
cordance with the provisions 60364-4-41: 2007 and IEC 60364-5-54: 2011.
Binding point is marked with a grounding symbol on the bottom right corner of the
mounting plate and there is a hole in the mounting plate and a label with grounding
symbol.
Disposal.
The station consists of materials that must not be disposed of with household waste.
Disconnect the entire energy supply and disassemble the product for disassembly and
dispose of it in accordance with local regulations.

EvoFlat 4.0 Flat Stations for apartments, single- and multi-family houses
Authorized personnel only
Assembly, start-up and maintenance work must
be performed by qualified and authorized per-
sonnel only.
Please observe instructions carefully
To avoid injury to persons and damage to the
device, it is absolutely necessary to read and ob-
serve 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 flat station is 95 °C.
The maximum operating pressure of the flat sta-
tion is 10 bar.
The risk of persons being injured and equip-
ment damaged increases considerably if the rec-
ommended permissible operating parameters
are exceeded.
The flat station installation must be equipped
with safety.
Warning of hot surface
The flat station has got hot surfaces, which can
cause skin burns.
Please be extremely cautious in close proximity to
the flat station.
Power failure can result in the motor valves being
stuck in open position. The surfaces of the flat sta-
tion 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 flat station installation, please make sure
that the flat station has not been damaged dur-
ing transport.
IMPORTANT — Tightening of connections
Due to vibrations during transport all flange con-
nections, screw joints and electrical clamp and
screw connections must be checked and tight-
ened before water is added to the system. After
water has been added to the system and the sys-
tem has been put into operation, re-tighten ALL
connections. Check that all hairpins in click con-
nections are completely pushed in.
Please notice
Interventions and reworking of our components
lead to the loss of warranty.
