4.2 Mode of operation The sewage produced is channelled into the pump chamber via the inlet, where it col-
lects. When the water level reaches the switch-on level, the pump is switched on. The
collected sewage is pumped into the on-site pressure pipe via the discharge pipe. When

en Transportation and storage
44 WILO SE 05
the switch-off level is reached, the pump is immediately deactivated. When switchgear
is used for the control, the pump is deactivated after the set follow-up time.
Pump chambers with two pumps operate according to the base load and peak load
principle. The pumps are switched on depending on the fill level. Pump cycling is carried
out after every pumping procedure. If one pump malfunctions, the other pump is auto-
matically used.

unit or pressure outlet are in the freezing zone, take the unit out of operation during
freezing periods.
NOTICE
Installation of the pump chamber outside buildings
Observe EN1610 and local regulations during ground installation!
ƒPrepare the installation site:
–Clean, free of coarse solids
–Dry
–Frost-free
ƒTake immediate countermeasures if there is a build-up of toxic or asphyxiating
gases!
ƒWork must always be carried out by two persons.
ƒInstall lifting equipment: even surface, clean, firm base. Warehouse and installation
location must be easily accessible.
ƒAttach the chain or wire rope to the attachment points with a shackle. Only use lift-
ing gear that has been technically approved.
ƒDo not stay within the swivel range of the hoisting gear.
ƒProvide threading strip for the installation of the connection cables.
ƒThe mounted switchgear is not overflow-proof. Install the switchgear at an ad-
equate height. Ensure good operation!
6.4.1 Note on fixation material The lifting unit can be installed on various constructions (concrete, steel, etc.). Select
the fixation material which is suitable for the relevant construction. For correct installa-
tion, observe the following instructions for the fixation material:

Installation and electrical connection en
Installation and operating instructions Wilo-DrainLift WS 40/50 Basic 49
ƒAvoid tearing or chipping of the construction surface, observe the minimum edge
distances.
ƒEnsure tight and secure installation, adhere to the prescribed borehole depth.
ƒDrilling dust impairs holding strength, always blow out or vacuum out the bore-
hole.
ƒOnly use components (e.g. screws, anchors, mortar cartridges) which are in perfect
condition.
6.4.2 Note on pipework The pipework is subjected to different pressures during operation. Pressure peaks can
also occur (e.g. when closing the swing check valve) which may be several times higher
than the pump pressure, depending on the operating conditions. These different pres-
sures put a strain on the piping and the pipe adaptors. In order to ensure safe and fault-
less operation, the piping and pipe adaptors must be checked based on the following
parameters and designed according to the requirements:
ƒPipes are self-supporting.
No tensile or compressive forces may act on the lifting unit.
ƒPressure resistance of pipework and pipe adaptors
ƒTensile strength of the pipe adaptors (= longitudinal force fit connection)
ƒConnect the pipes free of stress and vibrations.
ƒProvide a gate valve in the inlet and the pressure pipe on-site!
