3 Transport and interim storage
On receipt of the product immediately check for
transport damage. If damage has occurred, take
the necessary steps, within the defined periods,
with the transport company.
CAUTION! Danger of material damage!
There is a danger of damage if the product is
incorrectly handled during transport or storage.
• For transport, the pump may only be lifted or
carried using the brackets intended for that pur-
pose. The cable should never be used for lifting!
• During transport and temporary storage, the
pump must be protected from moisture, from
frost and from mechanical damage.
4 Intended use
The Wilo-Drain-TM submersible pumps are used
• to automatically drain pits and shafts („TM...A“),
• to keep out buildings and cellars at risk of flooding
dry,
• to lower surface water,
so far that waste water can't flow into the sewage
system via a natural gradient.
The pumps are suitable for slightly soiled water,
rainwater containing solids of max.
∅
3 mm and
suds.
The pumps are usually installed flooded
(immersed) and can only be installed vertically,
whether fixed or mobile.
Submersible motor pumps with connection lines
of less than 10 m are only approved (according to
EN 60335) for use within buildings, not for out-
door use.
WARNING! Risk of fatal injury!
The pump may not be used to empty swimming
pools / garden ponds or similar locations if there
are people in the water.
WARNING! Health risk!
Owing to the materials used, the pumps are not
suitable for drinking water! Polluted waste
water presents a health risk.
CAUTION! Danger of material damage!
Pumping materials which are not approved can
lead to damage to the product.
The pumps are not suitable for water containing
coarse impurities such as sand, fibres or faeces,
flammable liquids or for use in areas at risk of
explosion.
