Particular dangers on the compressor aggregate!
Warning!
1. Do not operate the flushing compressor below 5°C. If the flushing
compressor is undercooled – without connection voltage – wait until
the temperature has adjusted.
2. The compressor aggregate and lines become very hot when
operated and remain hot for some time after being switched off.
Contact with hot parts results in burns. It must be ensured that no
flammable materials are allowed to come into contact with these
parts.
3. The flushing compressor may only be operated in a well-ventilated
and dust-free room. The air sucked in by the compressor aggregate
must not contain flammable vapours or mist, e.g., paint solvents,
which could lead to a fire or explosion.
4. The cooling air flow on the compressor aggregate must not be
blocked. The system must thus be set up a distance of at least 50 cm
from any obstacles.

5. Use the accessories suitable for the specific application and
operating pressure and observe the relevant safety information.
6. Regularly check that the safety devices, electrical lines, safety valve
and tubes are in perfect condition.
7. In the case of any damage to electrical or pressurised components,
disconnect these from the mains or depressurise them and have
them checked/repaired by a specialist.
8. Hold or secure free tube ends as these could cause injuries by
whipping around. When releasing the tube coupling, the coupling
piece is to be held securely in order to avoid injuries caused by the
tube whipping back quickly.
9. Do not "play" with compressed air or aim it at others! Do not use
compressed air to clean clothes.
10.Ear protection must be used when working with the flushing

B Basic information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it comes to
the processing of drinking water (raw water). This operation manual
takes into consideration the current regulations and stipulates
information that you will need for the safe operation of your water
treatment system.
Among other things, the regulations stipulate that
only approved companies are permitted to make major modifications to
water supply facilities
and that tests, inspections and maintenance on installed devices are to
be performed at regular intervals.
In order to ensure drinking water quality, the issue of hygiene in
installations is becoming increasingly important. On the one hand, when
commissioning the installation there is the issue of cleaning by means of
flushing and then, depending on water hardness, the implementation of
measures to prevent lime scale. On the other hand, there are sanitation
measures such as sanitation flushing, disinfection, the removal of lime
scale and rust as well as the creation of a protective layer by means of
mineral dosing. These measures result from the latest requirements of
the German drinking water ordinance and standards, in particular DIN
EN 806-4.
The DVGW work sheet W 557 describes the "cleaning and
disinfection of drinking water installations"
It serves as the basis for avoiding and eliminating microbial
contamination and undesired deposits in drinking water installations as
defined by the drinking water ordinance. It describes the cleaning of
drinking water installations and the system disinfection of drinking
water installations or parts thereof and designates which disinfection
methods are to be applied and when as well as preventative measures
for avoiding microbial contamination.
The continuous disinfection of drinking water (drinking water
disinfection) is, in contrast, described in DVGW work sheet W 556
(under preparation).

2 | Differentiation between "system disinfection" and
"disinfection of the drinking water"
"System disinfection" is a complete measure for disinfection of a
drinking water installation and, during this time, drinking water is not
available to consumers. "System disinfection" is only a long term
solution if the causes of contamination are remedied.
"Disinfection of the drinking water" is transient long-term disinfection
before and/or during the technical sanitation of the drinking water
installation. The addition of disinfection by the water supplier must be
taken into account.
3 | Basis as per W 557, section 4
Drinking water must not impair the health of consumers. In addition to
the long-term protection of drinking water resources and preparation
and distribution in accordance with the generally recognised codes of
practice this also requires a properly planned, set up and operated
drinking water installation.
In particular, the drinking water installation can become contaminated
when newly constructed and during repairs. Contamination with
pathogens is a key danger. As long as the contamination remains
suspended or dissolved in the water, it is possible to flush it out of the
drinking water installation without any great difficulties. The first step in
remedying pollution is always cleaning. This is also true with microbial
contamination. Micro-organisms embedded in particles or corrosion
products are virtually impossible to kill off with disinfectants as these are
unable to access the micro-organisms. For this reason, the particles or
corrosion products must be removed by flushing or other cleaning
measures. System disinfection may be necessary as an additional safety
measure.
In existing drinking water installations with zinc-coated steel pipelines in
the hot water area, the water can become discoloured after even a brief
stagnation time due to corrosion. Flushing and other cleaning measures
are either not or only briefly effective in such cases. The dosing of
inhibitors can result in an improvement.

13
Regardless of whether there is immediate discolouration of the water or
not, corrosion causes deposits to build up. These can be due to
precipitation in the hot water area or from the flushing in of solid
particles from the supply network (e.g., rust particles). If there are
deposits, there is a risk that these will be mobilised when a large
amount of water is withdrawn and, consequently, the water is
discoloured or becomes clouded. Moreover, deposits facilitate the
multiplication of micro-organisms which can, in turn, result in microbial
pollution. In order to prevent this, the installation must be cleaned if it
contains deposits.
In drinking water installation which are planned, built, commissioned,
operated and maintained in accordance with the generally recognised
codes of practice, the microbiological sound quality of the drinking
water is ensured at the withdrawal point. In particular the following
must be ensured:
Operation as intended (including regular withdrawal of water at all
withdrawal points)
Temperature of the cold drinking water not in excess of 25°C
Temperature of the hot drinking water in the entire circulation system
not below 55°C
Regular maintenance
If the microbiological parameters of the limit values of the drinking
water ordinance are exceeded or if the technical action value of the
drinking water ordinance is reached or exceeded or the requirements of
the UBA (Federal Environmental Agency) recommendations are not
complied with, microbial contamination must be eliminated in the
interests of health protection. In such cases, system disinfection may be
additionally necessary after cleaning.
Note: Cleaning measures and system disinfection are only effective in
the long term if the causes of pollution, in particular in connection with
microbial contamination, have been remedied.
