4. Product introduction

4.1 Product description

The CWC-3 is a small, compact automatic lifting
station 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.
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.
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.
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 the warranty.
Solvents, acids and other chemicals can also cause
damage to the unit, and will invalidate the warranty.
