Compacta UZ, ZF, ZK
3.4 Return to supplier
1. Drain the lifting unit as described in the manual.
2. Always flush and clean the lifting unit, particularly if it has been used for
handling noxious, explosive, hot or other hazardous fluids.
3. If the unit has handled fluids whose residues could lead to corrosion damage in
the presence of atmospheric humidity or could ignite upon contact with oxygen,
the unit must also be neutralised and blown through with anhydrous inert gas
to ensure drying.
4. Always complete and enclose a certificate of decontamination when returning
the lifting unit. (ðSection13,Page59)
Always indicate any safety and decontamination measures taken.
NOTE
If required, a blank certificate of decontamination can be downloaded from the
following web site: www.ksb.com/certificate_of_decontamination

Compacta UZ, ZF, ZK
Design The lifting unit is provided with several horizontal inlet nozzles(1). The pump(4)
pumps the fluid handled into the vertical discharge line(8).
Function The fluid to be handled flows into the lifting unit through horizontal inlet nozzles(1)
and is collected in a gas-, odour- and water-tight plastic tank(7). When the level
sensor detects a defined fill level, the fluid is automatically pumped off to a level
above the flood level and towards the public sewer by either one or two pumps(4).
Sealing Two bi-directional mechanical seals supplied with environmentally-friendly oil.

4.7 Fluids handled
WARNING
Pumping of impermissible fluids
Hazardous to persons and the environment!
▷Only discharge permissible fluids into the public sewer system.
▷Check the suitability of pump/system materials.
Permissible
fluids
According to DIN1986-3 the following fluids can be discharged into sewer systems:
Water contaminated by domestic use, human and - as far as required and permitted -
animal faeces together with the necessary flushing water as well as stormwater in
case no other way of disposal is possible. 5)
Impermissible
fluids
Substances / water which must not be discharged into the sewer system are, amongst
others:
Solid matter, fibres, tar, sand, cement, ash, coarse paper, paper towels, cardboard,
debris, garbage, offal, grease, oil.
Waste water from installations situated above the flood level (EN12056-1).
Waste water containing hazardous substances (DIN1986-100), e.g. greasy waste
water from large-scale catering kitchens.
For drainage of greasy water a grease separator to DIN4040-1 must be fitted.
4.8 Collecting tank
The collecting tank is designed for unpressurised operation; that means the waste
water is stored in the tank in unpressurised condition and is then pumped into the
sewer system.
Size Total volume Effective volume
Litres Litres
UZ450 450 290
UZ900 900 580
5) Other types of waste water, e.g. industrial waste water, must not be discharged into the local sewer system without prior
treatment.

4.9 Noise characteristics
The sound pressure level depends on the local conditions and the duty point. It is
≤70dB(A).
4.10 Scope of supply
Depending on the model, the following items are included in the scope of supply:
Sewage lifting unit consisting of:
▪Either one or two gas-, odour- and water-tight collecting tanks made of impact-
resistant plastic material, with two waste water pumps
▪Flexible hose connections and hose clips
