4 Intended use
The DrainLift XL sewage lifting unit is an automatically operating wastewater lifting unit in
accordance with EN 12050-1 for backup-free drainage of sewage that does and does not
contain faeces and that originates from building discharge points below the backflow level.
The unit is only suitable for domestic sewage as defined in EN 12056-1. According to DIN
1986-3 [in Germany], no explosives or harmful substances may be introduced in high con-
centrations, such as solid substances, debris, ashes, garbage, sand, plaster, cement, lime,
mortar, fibrous materials, textiles, paper towels, diapers, cardboard, coarse paper, syn-
thetic resins, tar, kitchen waste, greases, oils, slaughterhouse waste, disposal of slaugh-
tered animals and animal waste (liquid manure, etc.), toxic, aggressive and corrosive
substances, such as heavy metals, biocides, pesticides, acids, bases, salts, cleaning agents
and disinfectants, dish-washing or laundry detergents, and such which have a high degree
of foam formation or swimming-pool water.
A grease trap should to be provided if greasy sewage accumulates.
According to EN 12056-1, no sewage from drainage objects may be introduced which lie
above the backflow level and can be drained by means of gravity.
NOTE: Make sure the national and regional applicable standards and regulations are
observed during installation and operation.
The details in the operating instructions for the switchgear should also be observed.
DANGER! Danger of explosion!
Sewage containing faeces can lead to gas accumulation in the collection reservoir,
which can ignite as a result of improper installation and operation.
• If the unit is used for sewage containing faeces, the valid safety regulations for poten-
tially explosive areas are to be observed.
• The switchgear is not protected against explosions and is only allowed to be operated
outside the explosive area.
• Breakdown barriers must be used if level sensors or float switches are used in poten-
tially explosive areas.
WARNING! Health hazard!
The materials used mean that the sewage lifting unit is not suitable for pumping pota-
ble water!
Contact with sewage poses a health hazard.
CAUTION! Risk of property damage!
Inappropriate materials in the system can cause damage to the product.
• Never discharge solids, fibrous substances, tar, sand, cement, ash, coarse paper, paper
towels, cardboard, debris, rubbish, animal waste, grease, or oil.
A grease trap should to be provided if greasy sewage accumulates.
• Improper use and overstraining causes damage to the product. The maximum possible
inflow quantity must always be lower than the volume flow of a pump at the respective
duty point.
