7 Setup/installation

7.1 Installation site

• The pressure-boosting system is installed in the
technical control room or in a dry, well ventilated
and frost-proof, separate room that can be locked
(e.g. as required by DIN 1988).
• Adequately dimensioned floor drainage (drain
connection or similar) must be provided in the
installation room.
• No harmful gases may enter the room or be pres-
ent there.
• Plan adequate space for maintenance work. The
main dimensions can be found in the supplied
installation plan. The system should be freely
accessible from at least two sides.
• To open the flap of the control device (on the left
when viewed from the operating part) and for
maintenance work in the control device, make
sure there is sufficient freedom of movement
(at least 1000 mm – cf. Fig. 14).
• The installation surface must be horizontal and
flat. A slight adjustment in height of the vibration
absorber in the base frame may be necessary to
achieve stabilisation. If this is necessary, undo the
counter nuts and unscrew the respective vibration
absorber slightly. Then re-tighten the counter
nuts.
• The system is designed for a maximum ambient
temperature of 0 °C to 40 °C at a relative humidity
of 50 %.
• Installation and operation in the vicinity of living
rooms and bedrooms is not recommended.
• To avoid the transmission of structure-borne
noise and to ensure a stress-free connection to
upstream and downstream pipes, compensators
(Fig. 9 – B) with extension limiters or flexible con-
nection pipe (Fig. 10 – B) should be used!

7.2 Installation

7.2.1 Foundation/bearing surface

The pressure-boosting system is designed for
installation on a flat concrete floor. The base
frame is mounted on height-adjustable vibration
absorbers as means of insulation against struc-
ture-borne noise.
NOTICE!
For transport reasons, the vibration absorbers may
not be installed upon delivery. Before installing
the pressure-boosting system, check that all of
the vibration absorbers are fitted and locked by
threaded nuts (see also Fig. 9).
Please note:
If the customer also wants to secure the installa-
tion to the floor, suitable measures must be taken
to avoid structure-borne noise transmission.

7.2.2 Hydraulic connection and pipes

When connecting to the public drinking water
mains, the requirements of the local water supply
company must be met.
The installation must not be connected until all
the welding and soldering work and the necessary
flushing and, if necessary, disinfecting of the pipe
system and the pressure-boosting system instal-
lation has been done (see 7.2.3).
The customer's pipes must be installed without
tension. Compensators with extension limiters or
flexible connection pipes are recommended for
this purpose in order to avoid stress at the pipe
connections and minimise the transmission of
system vibrations to the building installation.
In order to prevent the transmission of structure-
borne noise to the building, do not secure the pipe
clamps to the pressure-boosting system pipe-
work (for example, see Fig. 9, 10 - C).
The connection is made either on the right or left
of the system, depending on the site conditions.
It may be necessary to move blind flanges or
threaded caps that are already fitted.
The flow resistance of the suction line must be
kept as low as possible (i.e. short pipe, few elbows
and sufficiently large shut-off valves), otherwise
the protection against low water level may suffer
severe pressure losses in the event of high volume
flows. (Observe the NPSH of the pump and avoid
pressure losses and cavitation.)
NOTICE!
Where systems are fitted with casings it is recom-
mended that these are removed before connect-
ing the system and are refitted after all installation
and set-up work has been completed
(see Fig. 11a and 11b).

7.2.3 Hygiene (TrinkwV 2001)

The supplied pressure-boosting system meets the
standards of current technology and in particular
satisfies DIN 1988. It has been checked at the fac-
tory to make sure it functions correctly. Please
remember that when used in the drinking water
applications, the complete drinking water supply
has to be handed over to the operator in a perfect
state of hygiene.
Also observe the corresponding specifications in
DIN 1988 Part 2 Section 11.2 and the comments
on the DIN. According to TwVO § 5. Para. 4, this
also includes microbiological requirements, flush-
ing if necessary and also disinfecting in some cir-
cumstances. The limit values to be observed can
be taken from TwVO § 5.
WARNING! Contaminated drinking water is a
health hazard!
Flushing the pipes and system reduces the risk
of impairing the quality of the drinking water!
