• The electrical connection cable should be
adequately dimensioned in accordance with the
overall power of the system (see installation and
operating instructions and attached electrical
circuit diagrams for the pump and control device).
• The external fuse protection should be provided in
accordance with DIN 57100/ VDE0100 part 430
and part 523 (see installation and operating
instructions and attached electrical circuit
diagrams for the pump and control device).
• As a protective measure, the system should be
earthed according to regulations (i.e. according to
the local regulations and conditions); designated
connections are identified (see also the circuit
diagram).
DANGER! Risk of fatal injury!
As a protective measure against dangerous
contact voltages:
• For a pressure-boosting system fitted with a
frequency converter, a universal-current-
sensitive residual-current device with a trigger
current of 300 mA should be installed.
• The protection class of the system and of the
individual components can be found on the
rating plates and/or data sheets.
• Further measures/settings etc. can be found in
the installation and operating instructions as
well as the circuit diagram for the pump and/or
control device and/or main switch.
8 Commissioning/shutdown
Recommendation: We recommend that the initial
commissioning of the system is performed by the
Wilo customer service department. Contact your
dealer, your nearest Wilo representative or the
central Wilo customer service department
directly.
8.1 General preparations and control measures
• Check that all on-site wiring has been performed
correctly, in particular the earthing, prior to the
initial start-up.
• Check that the pipe adaptors are not under stress.
• Fill the system and carry out a visual inspection for
leakages.
• Open the shut-off valves at the pumps and in the
suction and pressure pipe.
• Open the pump venting screws and fill the pumps
slowly with water to allow the air to escape
completely.
Caution! Risk of material damage!
Do not allow the pump to run dry. Dry running
destroys the mechanical seal and leads to motor
overloading.
• In suction mode (i.e. negative level difference
between break tank and pump), the pump and the
suction line must be filled via the opening in the
venting screw (use a funnel).
• If a diaphragm pressure vessel (optional or
accessory) is installed, check that it is set to the
correct supply pressure (see Fig. 3 and 4).
• To do so:
• Depressurise the tank on the water side (close
the flow-through fixture (A, Fig. 3) and allow the
residual water to drain (B, Fig. 3)).
• Check the gas pressure at the air valve (top;
remove dust cap) of the diaphragm pressure
vessel with an air pressure gauge (C, Fig. 3).
If necessary, correct the pressure if too low
(PN 2 = pump cut-in pressure pmin less 0.2-
0.5 bar or value given in the table) on the tank
(see also Fig. 3) by adding nitrogen (contact Wilo
customer service).
• If the pressure is too high, release nitrogen from
the valve until the required value is reached. Put
the dust cap back on.
• Close the drain valve on the flow-through
fixture and open the flow-through fixture.
• In the event of system pressures > PN 16, observe
the filling instructions according to the
manufacturer’s installation and operating
instructions for the diaphragm pressure vessel.
DANGER! Risk of fatal injury!
Excessive supply pressure (nitrogen) in the
diaphragm pressure vessel leads to damage or
destruction of the tank and thereby also to
personal injury.
Observe the safety measures for handling
pressurised vessels and technical gases.
The pressure specifications in this
documentation (Fig. 4) are given in bar(!). If
other units of pressure measurement are used,
convert the figures correctly!
• In the case of an indirect connection, check that
the water level in the break tank is adequate, or
with a direct connection, that the inlet pressure is
adequate (at least 1 bar).
• Check for proper installation of the correct
dry-running protection (Section 7.2.4.).
• Position the float switch or electrodes for
protection against low water level in the break
tank to ensure the system is securely switched off
at the minimum water level (Section 7.2.4).
• Check the motor protection switch in the control
device (only if present!) to make sure that the
correct rated current is set according to the
specifications on the motor rating plates. Observe
the installation and operating instructions for the
control device.
• The pumps may run only briefly against the closed
gate valve on the pressure side.
• Check and set the required operating parameters
on the frequency converter of the pump and
control device according to the attached
installation and operating instructions.
