Installation and operating instructions • Wilo-DrainLift BOX • Ed.06/2022-10
–
Frost-free
–
Well lit
•
Ensure operating space has sufficient ventilation.
•
Ensure a clearance area of min. 60 cm (2 ft) around the floor drain.
•
Provide threading strip for the installation of the connection cables.
•
All connection cables must be laid properly. The connection cables must not pose any
risk (i.e. tripping, damage during operation). Check whether the cable cross-section and
the cable length are sufficient for the selected installation type.
•
The mounted switchgear is not overflow-proof. Install the switchgear at an adequate
height. Ensure good operation!
•
In case of a floor-mounted installation, install buoyancy safeguards. Note the installa-
tion instructions.
6.4.1
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 pressures put a
strain on the piping and the pipe adaptors. In order to ensure safe and faultless operation,
the piping and pipe adaptors must be checked based on the following parameters and de-
signed according to the requirements:
•
Pipes are self-supporting.
No tensile or compressive forces must act on the lifting unit.
•
Pressure resistance of pipework and pipe adaptors
•
Tensile strength of the pipe adaptors (= longitudinal force fit connection)
•
Connect the pipes free of stress and vibrations.
6.4.2
Preparing the lifting unit for in-
stallation
Prior to installation of the lifting unit, complete the following tasks:
•
Check the position of the pumps.
•
Check the level control.
•
Open the connection port.
•
Install accessories:
–
Mini float switch
An additional mini float switch must be installed for the high water alarm.
–
Collar
NOTICE! If watertight concrete (white tub) is sealed, an additional collar (available
as an accessory) must be installed on the neck of the tank!
Checking the position of the pumps
The pumps are mounted and positioned in the factory. The pumps may shift during trans-
port, which would impair proper function of the float switches. For this reason, check that
the pumps are in the correct position before installation, and if necessary correct according
to the illustrations.
