ance with Section 4 of the operating instructions.

3 Transport and interim storage
When you receive the domestic water system,
immediately check it for transport damage. If you
discover transport damage, discuss with the cou-
rier company what measures to take, complying
with the relevant notification deadlines!
CAUTION! Risk of damaging the domestic water
system!
Danger of damage due to incorrect handling
during transportation and storage.
The domestic water system must be protected
against moisture, frost and mechanical damage
when in transit. The domestic water system must
never be exposed to temperatures beyond the
range -10 °C to +50 °C during transport or stor-
age.
4 Application (intended use)
With its series of different domestic water sys-
tems, Wilo is offering water-supply units for
domestic, DIY and garden applications. Depending
on the pump used, the domestic water systems
are suitable for:
• pumping water out of containers, ponds, streams
and wells, for water supply, irrigation, sprinkling
and spraying in the domestic context.
Non-self-priming or self-priming pumps are used,
depending on the application.
Non-self-priming pumps which can operate in
inlet mode (e.g. from an open container) but are
not self-priming, are allowed to be connected to
the public water supply system directly (Fig. 2).
Self-priming pumps are equipped with air separa-
tion technology in the pump hydraulics, which
enables them to evacuate air from a suction pipe
(e.g. from a well) (Fig. 3). These are not allowed to
be connected to the public water supply system,
in order to avoid any negative effect on the mains
pressure.
Permitted fluids:
• Water without any solid or sedimentary particles
(process water, refrigerating water, cooling water
and rainwater)
Use with other fluids or additives requires
approval from Wilo
