5.2 STARTING AND OPERATING INSTRUCTIONS
Run the water from the bathroom or from kitchen appliance connected to the pump and check
that connections are water tight and that the pump starts and stops correctly.
The pump starts automatically as soon as the bath, the shower or the sink begins to drain. It
shuts down when all the water has been drained.
Note that the pump will work intermittently as the pump will turn on and off or several cycles until
it discharges all the water.
“ATTENTION”: Never drain alkaline or acidic liquids, solvents, Oils, paints paint strippers, food
leftovers, or bleaches that may jam, damage or corrode this appliance.
In case of power failure, do not use any of the bathroom appliances connected to the pump,
because they will not function properly until power is restored.
Never submerse pump entirely under water nor allow water to seep in through electric wire
access.
Make sure that all faucets are fully shut otherwise the motor may stop and start, leading to a short
circuit. This may also lead to flooding.
If you do not plan to use the pump for a long period of time (vacation, major power shortage,
maintenance, renovation), shut off water).
In regions prone to frost and freezing, the appliance must be adequately protected against
freezing. This requires emptying all pipes and the pump body. Antifreeze may be used to protect
the system. Pour 1 liter of antifreeze into a sink connected to the pump. This will activate the
pump and any remaining water will be replaced by antifreeze. Neither labor nor parts are covered
