Pentair JUNG PUMPEN WCFIX PLUS Instructions De Service page 12

ENGLISH
Connect the DN 50 inlet pipes using
plug-in seals or, in the case of front-wall
installations, with sleeves and clips.
Connect the pressure pipe with the
pressure port discharge elbow and hose
clips.
Buoyancy prevention
Sewage lifting units must be protected
against buoyancy. The installation site
should never be flooded.
A hole must be drilled for the wall plug,
using a long drill with a diameter of 10
mm. The anti-buoyancy hanger bolt
should later lie on the tank or have just
a small amount of play. Insert the wall
plug and screw the M8, 200-mm-long
hanger bolt tightly into place.
Emergency disposal
12
To drain the tank in an emergency, a
section of garden hosepipe be con-
nected to the tank at the bottom on the
right-hand side. First, you will have to
open up the 13-mm-diameter port by
drilling through it with a spiral drill
(maximum diameter: 9 mm). Push the
hosepipe onto the port and secure it
with a hose clip (tightening torque: 1.5
Nm). Make sure that the outlet opening
of the hosepipe is securely sealed.
Before installing the unit, fasten the
DN 50 and DN 100 connecting sleeves
to the discharge pipes using the clips
(supplied). Make sure that they are
properly fitted and do not leak.
ATTENTION! All of the pipe connections
must be properly sealed and free of
leaks.
The sticker that is supplied with the unit
and shows symbols giving instructions
for use must be attached where it can
be clearly seen by people using the toi-
let: for example above the toilet lid or on
the inside of the lid.
ATTENTION! Putting prohibited mate-
rials into the toilet can cause malfunc-
tions, damage the unit and invalidate
the warranty.
Practical tips
After using commercially available
cleaning agents, flush the toilet sever-
al times to ensure that no aggressive
cleaning agent residues are left in the
WCFIX PLUS.
Toilet rim blocks must be fastened par-
ticularly securely to the toilet bowl rim
so that they cannot be flushed into the
unit.
SERVICING
Only qualified electricians may
carry out electrical works to the
WCFIX PLUS.
Before carrying out any work,
always disconnect the WCFIX
PLUS from the power supply
and ensure that it cannot be switched
on again by other persons.
When used properly, the WCFIX PLUS
requires little maintenance. The unit
should be checked at least once a year,
however, to ensure that all of the con-
nections are still watertight.
The activated carbon filter should be
changed once a year.
Clearing blockages after an alarm
1. Open the maintenance hatch.
2. If the pump is sluggish or blocked,
it can be set in motion again using a
screwdriver, without any further disas-
sembly. To do this, remove the stopper
from the hole in the cover. Insert a long
screwdriver (Torx 30 or grub-screw H5)
through the hole in the cover. Turn the
screwdriver gently until it engages with
the slot in the motor shaft and then turn
the shaft forcefully in both directions to
clear the blockage.
Then connect the mains plug to
the power supply temporarily,
to check that the pump now
works properly.
3. If the unit still does not pump nor-
mally after completing step 2, then the
motor/pump unit must be removed.
Before dismantling the unit, any wa-
ter that is backed up in the toilet bowl
and in the unit must be drained off.
The emergency draining procedure can
be carried out using an electric drill
(n > 2000 RPM anticlockwise) and a
130-mm-long screwdriver bit.
