Commissioning

Installation and operating instructions Wilo-SiClean
All parts of the system are joined by threaded connections. Use the
provided sealing glue to seal the couplings (follow the directions for
its use).
CAUTION! Damage to the pump!
Danger of damage due to incorrect handling.
• Do not forget the gaskets for the circulation pump and the hoses.
• Check the flow direction of the balancing valve (pos. 9) and the circu-
lation pump (pos. 2).
NOTE
The inlet/outlet taps (models 0,5/1/2) or the outlet taps (models 3/4/
5) pass through the separator, the connections may be made on either
the left or the right side. Use the plugs provided to blank the unused
ports.
Whatever the configuration of the installation (new or old), the sys-
tem must be by-pass connected on the network return (Fig. 2). The
diameters of the pipes to which the SiClean is connected must be at
least as large as those of the system itself. The suction nozzle must be
on the bottom part of the main pipe, the discharge nozzle on the
upper part (Fig. 2). The distance between the two nozzles must be at
least equal to the height of the separator, to avoid turbulence in the
pipes.
• Connect the suction, discharge, and sludge disposal using the diame-
ters stated in the table above. These pipes must be installed free from
stresses.
• To isolate the system and allow adjustments and servicing, interpose
valves on the suction and discharge lines.
• The sludge evacuation pipe must have a full disconnection to outfall
at atmospheric pressure. The diameter of this pipe must be at least as
large as that of the flush valve (pos. 6).
DANGER! Risk of fatal injury!
Improper electrical connections can lead to fatal electrical shocks.
• Have the electrical connection established by an electrician
approved by the local electricity supplier only, in accordance with
local regulations.
• Observe the installation and operating instructions for the acces-
sories!
To make the electrical connection, the corresponding installation and
operating instructions and attached electrical circuit diagrams must
be observed. General points to be considered are listed below:
• The type of current and voltage of the mains connection must comply
with the details on the rating plate and the circuit diagram of the
switch box.
• The electrical connecting cable must be adequately dimensioned
according to the total power of the system (see rating plate).
• Connect the switch box and the circulation pump with the supplied
cable (pos. 16), and refer to the installation instructions of the circu-
lation pump.
• As a protection measure, the system must be earthed according to
the regulations (i.e according to the local regulations and circum-
stances).
We recommend that the initial commissioning of SiClean is performed
by the nearest Wilo customer service agent or ask your central cus-
tomer service department.
