3 Transport and interim storage
The DEA is supplied on a pallet, on transport
boards or in a crate and is film-wrapped to protect
it against moisture and dust. Transport and stor-
age instructions marked on the packing must be
observed.
CAUTION! Risk of damage!
The equipment must be transported by means of
authorised load carriers. Stability of the load
must be ensured, since the pumps have been
constructed in a way that shifts their centre of
gravity the top (top-heavy) . Transport straps or
ropes must be secured to the existing transport
lugs or placed around the base frame. The pipes
are not designed to withstand loads and should
not be used to secure loads in transit.
CAUTION! Risk of leakage!
Loading the pipes in transit can result in leak-
age!
The transport dimensions, weights and necessary
passageways or transport space of the unit are
given in the attached installation plan or other
documentation.
CAUTION! Risk of damage!
The system must be protected against moisture,
frost and heat and also mechanical damage by
means of suitable measures!
If damage to the packing is determined when
unpacking the DEA and accessories included in the
shipment that may have been caused by falling or
a similar event,
• carefully inspect the DEA or the accessory parts
for possible defects and
• notify the delivery company (forwarder) or Wilo
after-sales service, even if there is initially no
obvious damage.
After removing the packing, store or install the
unit according to the installation conditions
described (see section entitled Installation).

4 Intended use
Pressure boosting systems (referred to as DEA) are
designed for boosting and maintaining the pres-
sure of larger water supply systems. They are used
as:
• Potable water supply systems, primarily in high-
rise apartments, hospitals, offices and industrial
buildings, the structure, function and require-
ments which comply with the following standards,
guidelines and directives:
• DIN 1988
• DIN 2000
• EU Directive 98/83/EC
• Drinking Water Ordinance - TrinkwV2001
• DVGW regulations,
• Industrial water supply and cooling systems,
• Irrigation and sprinkling systems.
The automatically controlled multiple pump sys-
tems are either supplied from the public potable
water mains directly (connected directly) or indir-
ectly (connected indirectly) using a break tank.
These break tanks are sealed and are not pressur-
ised, i.e. they are under atmospheric pressure.
