4. Product introduction

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.

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.

5.2 Maintenance

The lifting station does not require any special

maintenance, but we recommend that you check

operation and pipe connections at least once a year.

Change the carbon filter once a year.

See section 5.4 Service instructions.

5.3 Adjustment of run time

The default setting ensures proper operation in most

pipes. If the pipes are particularly long or short, it

may be necessary to adjust the run time.
