4 Intended use

The DrainLift XS-F is a sewage lifting unit for restricted use (according to DIN 1986-100
and DIN EN 12050-3) which is ready to be directly connected to an wall hung toilet. The
unit fulfils all conditions for front wall installation, especially where a toilet or shower must
be installed, particularly in cellars or basements, during modernisation or restoration work.
Faeces and toilet paper are pumped into the on-site collector pipes.
The unit disposes of sewage for a single toilet or an additional washbasin, a shower and/or
a bidet, where the waste water cannot be directed to the canalisation via a natural fall, or
for waste water which accumulates below the backflow level.
• All connected drainage points must be in the same room as the unit (limited use of the lif-
ting unit).
• It is designed for a small number of users and there must be another toilet above the back-
flow level.
• The connection of additional drainage fixtures such as a washing machine, dishwasher or
bathtub is prohibited by DIN EN 12050-3.
• The unit must be operated with a cistern with a capacity of at least 6 litres. When the flus-
hing water is less than 6 litres, for example on dual-flush toilets, satisfactory operation is
not guaranteed.
• The system is only suitable for domestic sewage as defined in EN 12056-1.
CAUTION! Risk of damage!
Inappropriate materials in the system can cause damage to the product.
• Never put hygiene products, paper towels, moist toilet paper, leftover food, solvents,
chemicals, grease etc. in units for restricted use.
• Never put solid materials, fibrous materials, tar, sand, cement, ash, coarse paper,
rubble, refuse, butcher's waste, grease, oil or swimming-pool water in the unit.
