Vacuum relief valve
Fig. 15: Vacuum relief valve installation
If the end of the pressure pipe is lower than the pump chamber,
underpressure in the pressure pipe can cause the pump chamber to
be drained dry. A vacuum relief valve can be installed to prevent the
pump chamber from being drained dry.
Installation is only possible in conjunction with the flush con-
nection as the vacuum relief valve is fitted on the Storz coupling.
During installation, pay attention to the alignment of the vacuum
relief valve to ensure that installation/dismantling of the pump
is possible at any time without danger and to guarantee proper
functioning of the gate valve.

5.3. Electrical connection

RISK of death due to electrocution!
Incorrect electrical connections can cause fatal electric shocks.
Electrical connections may only be carried out by a qualified
electrician approved by the local energy supply company, in
accordance with locally applicable regulations.
• The electrical connection for the individual components must com-
ply with the associated installation and operating instructions.
• The pumping station must be earthed in line with the regulations.
Equipotential bonding must be installed in accordance with the valid
regulations.

6. Commissioning

The "Commissioning" chapter contains all the important instructions
required by the operating personnel for safe commissioning and
operation of the pump chamber.
The following general conditions must always be met and checked:
• The maximum inflow must be lower than the maximum output of
the pump installed at the relevant duty point.
• Level control device switching points
These general conditions must also be checked after a lengthy
period without operation, and any defects detected must be
repaired!
These instructions must always be stored with the pump chamber
or in a designated location where they are always accessible to all
operating personnel.
To prevent damage and injuries to personnel during commissioning
of the pump chamber, the following points must be observed:
• Commissioning may only be performed by qualified and trained
personnel in accordance with the safety instructions.
• All personnel who work on the pumping station must have received,
read and understood these instructions.
• All safety equipment and emergency stop mechanisms on the
pumping station are connected and have been tested for proper
functioning.
• Electrical engineering and mechanical adjustments must be carried
out by qualified personnel. A second person must always be present
when working in the pump chamber. If there is a risk of toxic gases
forming, sufficient ventilation must be ensured.
• The pump chamber is suitable for use under the specified operating
conditions.
• No personnel may be present in the pump chamber during activation
and/or operation.
It is recommended to have commissioning carried out by Wilo
customer service.
