5.4 Service instructions

Thanks to the product design, service is easy in case
of malfunction or a blocked pump.
Impeller or grinder stuck
1. Disconnect the power supply.
2. Unscrew the plug in the cover.
3. Insert a screwdriver (min. 110 mm) through the
plug hole and into the slot of the shaft end.
Turn the shaft right and left to free the impeller or
grinder from dirt.
4. Fit the plug and switch on the power supply to
check if the impeller or grinder can rotate freely.
Operation by means of a power drill
If the product cannot be operated by electrical
power, disconnect the power supply and empty the
toilet and tank by means of a power drill.
Pressure switch pipe blocked
The pressure switch unit can be removed separately.
1. If the water level in the tank is above the motor
flange, disconnect the power supply and drain
the tank by means of the drain hose.
2. Unscrew the cover.
3. Pull out the complete pressure switch.
4. Check and clean the pressure switch pipe.
Make sure that the little tube in the top of the pipe
has not become blocked while you have cleaned
the pipe!
5. Lubricate the sealing area of the pressure switch
for easier fitting.

Foreign body in the tank
CAUTION
Sharp element
Minor or moderate personal injury
- Beware of the sharp edges on the
grinder. Wear protective gloves.
1. If the water level in the tank is above the motor
flange, disconnect the power supply and drain
the tank by means of the drain hose. See image
3.1 in the appendix.
2. Unscrew the cover.
3. Remove the four screws of the motor flange.
4. Lift the motor flange to reduce the compression
of the O-ring. Insert a screwdriver into the notch
underneath the power supply cable and press it
down.
5. Lift out the complete motor-pump unit by the
handles.
Lift the unit vertically before tilting it!
6. Check and clean the tank and impeller or grinder.
Carbon filter
Replace the carbon filter once a year to ensure
sufficient filter function.
Instead of using a carbon filter, Sololift can
also be vented through a venting pipe. In
this case a venting valve is needed.
