4. Product introduction
4.1 Product description
The C-3 is a small, compact automatic lifting station
suitable for pumping grey wastewater off places
where it 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
units served by the lifting station.

The product is suitable for pumping grey wastewater
from a washing machine, dishwasher, kitchen sink,
bath tub, shower or water softeners.
The product is only suitable for domestic
use.
The product must be fastened to the floor
to prevent uplift and turning.

temperature of 20 °C and maximum 15 % of salt.
Ordinary liquids for cleaning of the appliances
