Pentair Jung Pumpen WCFIX PLUS Instructions De Service page 12

ENGLISH
NOTICE! If a connecting pipe is fitted between the WCFIX and
the toilet, this will result in malfunctions. This method of ins-
tallation does not comply with the approval of the Deutsches
Institut für Bautechnik (the German approval body for const-
ruction products and types of construction).
The distance between the wall and the end of the connection
branch of the toilet must be at least 220 mm if the WCFIX PLUS
is to be installed without moving the toilet.
NOTICE! The connection pipes from the shower and washba-
sin must be fitted with a so-called back-up bend, installed as
close to the unit as possible. The pipe invert of this bend must
be at a height of at least 75 mm above the mounting surface on
which the unit is fixed. Air pockets in the connecting pipe can
cause run-off problems and the water could back up. To pre-
vent back-ups, the inlet pipe from the shower must be vented
at its highest point. The ventilation pipe can be connected into
the tank ventilation.
When installing a shower, the priority valve supplied with the
unit must be inserted into the corresponding connection port.
NOTICE! We recommend installing a shut-off valve after the
check valve in the pressure pipe. This allows the check valve
to be serviced easily.
In the case of front-wall installations, the WCFIX PLUS should
be installed before the panelling is fixed to the frame. This
makes it easier to install the unit and to check the connections.
Instructions regarding ventilation of the tank
The tank ventilation is essential for proper operation of the
system and must be fed out through the front-wall panel. A
pipe with a nominal diameter of 40 mm and high temperature
resistance (not supplied) can be used to connect the system to
the ventilation insert (supplied) or to a roof vent. This connec-
tion pipe ensures that no damp air can escape from the tank
into the room in which the WCFIX PLUS is installed, where it
could otherwise cause hidden moisture-related damage or
mould growth. An activated carbon filter is supplied with the
unit to minimise unpleasant odours. The protective film must
be removed before use. The filter can be replaced and serviced
from outside via the ventilation grille. The ventilation insert
can be fixed into the front wall at the top, the side or the front
of the wall, if required. However, it must be installed above the
height of all of the fixtures that are connected to the WCFIX
PLUS.
If the WCFIX PLUS is not installed behind a front wall, an acti-
vated carbon filter can be fitted at the tank.
NOTICE! Activated carbon filters reduce unpleasant odours,
whereas a roof vent prevents them.
A hole 76 mm in diameter must be drilled for the installation of
the ventilation system.

Cross-section through the finished wall where the ventilation
insert is installed. If the system is ventilated via a roof vent,
then the ventilation insert and activated carbon filter are not
required.
Instructions regarding the modules for front-
wall installation
The WCFIX PLUS is compatible with all commercially available
front-wall installation systems that have a footprint depth of at
least 18 cm.
NOTICE! A maintenance hatch opening measuring at least 60
x 45 cm must be created. An installation kit for integrating a
frameless, tiled maintenance hatch cover can be ordered se-
parately, as an accessory (JP41075).
MOUNTING
Before commencing work, check the contents of the package
and the conditions that need to be taken into account at the
installation site. The inlet pipes and the pressure pipe must
be installed in advance in the room where the unit is to be in-
stalled.
Fitting the connection pipes
Fit the toilet connector into the desired inlet opening. Make
sure that the sealing lip is fitted properly in the tank.
For the other inlets, remove the stopper and then use DN 50
plug-in seals or, in the case of front-wall installations, use the
connection sleeves with hose clips.
NOTICE! When installing a shower, the priority valve supplied
with the unit must be inserted into the corresponding connec-
tion port.
Before fitting the priority valve, lubricate the seal area with
petroleum jelly. Then insert the valve into the open inlet port,
making sure that it locks properly into place. Check that the
valve flap works properly.
Seal the unused toilet inlet port
Insert the sealing ring into the unused toilet inlet port, making
sure that that the sealing lip is fitted properly in the tank. Then
grease the seal and close the opening by fitting the cover.
