General Instructions; Putting The System Out Of Operation/Intermediate Storage - Kessel Aqualift S LW 600 Installation, Operation And Maintenance Instructions

5.1 General instructions

When putting lifting stations into operation, EN
12056-4 must be heeded.
After the complete and correct installation of the comple-
te system and all the additional parts as well as the pipe
and electrical installations, the system can be put into
operation.
Important:
This initial operation may only be carried out by authorised
specialist staff. Do not put the system into operation if
there is any damage to the motor, switch unit or cables vi-
sible. Always follow the safety instructions in chapter 1 of
this manual. Do not use the pump for pumping media the
materials are not resistant to.
Make sure before you put the system into operation that the
nominal voltage and type of current specified for the system
correspond to the nominal voltage and type of current on site.
Check the system installation/cabling carefully before you
put the system into operation. Is the protective earthed con-
ductor working? Have the relevant standards/guidelines
been heeded, particularly with a view to the potentially ex-
plosive area?
Before putting the pump into operation, make sure that the
electrical connection has been checked and carried out:
- Floating switch version
Connect the connection cable with the plug element to the
mains.
- Tronic/Duo version
Read the separate installation instructions for the switch
unit.
Inspection:
- of the operating data
- the electrical connections
- correct pump installation
The pump may only be operated in such a way that no air
can get into the pump housing.
Initial operation
Before operation, make sure that the liquid level never drops
to below the switch-off level of the float switch.
In addition, the system must be checked for leaks, and any
leaks found must be eliminated.
.
5. Operation
Operating the pump without water inflow (running
empty) will lead to increased wear and must
be avoided!
• Operating voltage
The maximum permissible deviation for the operating
voltage is: ± 10 %
• Density of the pumping medium
Max. density 1.1. An enquiry must be made if the value
is higher.
5.2 Putting the system out of operation/intermediate
storage
• Storing new pumps
Store the pump vertically in a dry place in the original
packaging
Pump remains installed with standby check
To ensure continual stand-by, the pump unit should be
subjected to a functional run once every quarter (for about
1 minute). This requires the water level to be sufficiently
high.
Pump is removed and stored
Before the pump is stored, it must be inspected and ser-
viced.
