7. Installation and electrical connection

WARNING! Physical injuries
The applicable regulations for the prevention of
accidents must be complied with.
WARNING! Risk of electric shock
Any danger posed by electricity must be eliminated.
7.1 Receipt of the product
Unwrap the product and remove the packaging
while ensuring respect for the environment.
7.2 Mechanical installation
WARNING! Risk of property damage!
Position the product horizontally on a level surface.
• Inspect the tank cleanliness; if necessary, clean it
with water
• Select a location appropriate for the device's dimen-
sions so that the fittings are accessible (fig. 1)
• Install the product in a dry, well ventilated place
away from frost. The product is not designed for
external use
• Do not install anything underneath the product in
case of drainage of condensate via the overflow
• Do not cover the product
NOTE: The pump set (fig. 1) of the product may,
based on the location of use, be inserted into
the tank on the right or on the left (based on the
model).
• Unclip the cover (fig. 5)
• Move the pump set (fig. 6)
• Reattach the cover (fig. 7)
• In the case of wall fixation:
Mark the drilling holes with a centre-to-centre dis-
tance of 75 mm (Wilo-Plavis 011-C), 105 mm (Wilo-
Plavis 013-C) and 165 mm (Wilo-Plavis 015-C).
Use bolts that are customised for the material of
the wall.
Attach the product to the wall using 2 Ø 4 mm
screws.
7.3 Connection to piping network
• Inspect the tank cleanliness; if necessary, clean it
with water
WARNING! Danger due to malfunction!
Non-compliant inlet and drainage fittings cause
installation malfunctions. Flexible inlet and
drainage pipes must not in any case be jammed
or bent after assembly. The bending radius of the
drainage pipe must be greater than 60 mm.
WARNING!
The condensates from boilers are aggressive due
to their acidity. Always wear gloves and protec-
tive glasses for maintenance work.
Ensure the height of the lifting station does not
exceed the delivery head.
• Notch (based on the model) the plugs (fig. 3,
item 5) for the inlet pipes of less than 32 mm
in diameter, or remove the plugs if the pipe is
between 32 and 40 mm in diameter.
A pipe with an 8 mm internal diameter is pro-
vided for the drainage of condensate (based on
the model).
• Connect the inlet pipe(s) for condensate to the
input holes (fig. 3, item 5).
• Connect the drainage pipe to the non-return
valve (fig. 3, item 8) while trying not to mechani-

cally damage the product, the pipe must insert
freely into the non-return valve. If necessary,
detach the non-return valve (fig. 8), connect the
pipe, and reassemble the set on the product
7.4 Electrical connection
DANGER! Risk of electrocution!
The electrical connection will only pose a risk of
electrocution if it is not connected properly.
The electrical connection must only be carried
out by an electrician approved by the local
energy supplier and in compliance with the
applicable local regulations.
The system must be supplied with a circuit includ-
ing a residual differential current device (RCD), with
an allocated operating differential current that does
not exceed 30 mA.
• The system is ready to be connected.
The current type and the network supply voltage
must correspond with the indications on the rating
plate.
7.5 Connection of alarm cable (based on the model)
NOTE: Take into account the installation and
operating instructions for each device during
connection of the alarm cable.
DANGER! Risk of electric shock!
Before connecting the alarm cable, make sure
that the unit is voltage-free.
Max contact load: see table § 5.1
The alarm switch is delivered in the normally
closed position (NC). This means that the contact
opens when the alarm level is reached or excee-
ded. In order to use the normally open contact
(NO) (so that the contact closes when the alarm
level is reached or exceeded), carry out the fol-
lowing steps:
• Disengage the latch on the cover (Fig. 3, item 4).
• Rotate the alarm switch (Fig. 4, item 15) by half a
turn in the direction of the arrow (Fig. 4).
• Snap in the cover.
NOTE: When the unit is voltage-free, the alarm
switch functions as a normally open contact
(NO).
NOTE: To return to the normally closed position
(NC), rotate the alarm switch again in the direc-
tion of the arrow.
8. Commissioning
Function check
• Connect the mains plug
• Fill the product with clear water and ensure that
the product starts up when the high level is
reached (fig. 4, item 12)
• Ensure that the product stops once the low level
is reached (fig. 4, item 11)
For Wilo-Plavis 013-C and Wilo-Plavis 015-C:
In order to check the function of the alarm, discon-
nect the product electrically, fill the installation
with clear water until overflow, and reconnect the
product electrically. The visual alarm (and buzzer,
based on the model) is activated as well as the
alarm relay.
The Wilo-Plavis 015-C includes a bag with gran-
ules for pH neutralisation in the scope of delivery.
