4. Product introduction
English (GB)
4.1 Product description
The WC-1 and WC-3 are small, compact automatic
lifting stations suitable for pumping domestic
wastewater and sewage off places in private
dwellings where wastewater cannot be led directly to
the sewer by means of a natural downward slope.
If you are away for a long period (e.g. holidays) we
recommend that you turn off the water supply to the
toilet served by the unit.
This product is a domestic unit. Toilets connected to
this unit can be used like any normal toilet, and
require minimum maintenance. The unit will operate
automatically as soon as the required level of water
enters the tank.
Only the disposal of toilet paper, faecal matter and
wastewater will be covered by warranty. Any damage
due to foreign bodies such as cotton, condoms,
sanitary towels, wet wipes, food, hair, metal, wood or
plastic objects, will not be covered by warranty.
Solvents, acids and other chemicals can also cause
damage to the unit, and will invalidate the warranty.
4.2 Intented use
The product is only suitable for pumping wastewater
from a cabinet shower, bidet and/or washbasin as
well as sewage from a toilet.
Applications according to EN 12050-3.
Not for public and heavy commercial or
industrial use, only a limited number of
users.
Installation with direct connection to a
toilet and in the same room as sanitary
appliances.
A second toilet must be available above
the backflow level.
The product must be fastened to the floor
to prevent uplift and turning.
4.3 Pumped liquids
Domestic wastewater and sewage containing toilet
paper and faeces.
Ordinary liquids for cleaning of the appliances
connected. pH value: 4-10.
The product is designed for flush volumes of 4, 6 and
9 litres. A 4-litre flush is permissible only if the
amount of solids in the pumped liquid is small.
The product must not pump harsh
chemicals or solvents. See the quick
guide.
5. Servicing the product
Always use original accessories from Grundfos to
ensure safe and reliable operation.

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 (accessory).
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 (accessory).
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.
