Note
regulations and accepted codes of good
practice.
1. Check that all hoses and connections are tight.
2. Connect the power supply.

8.1 Checking the function

Pump operation
Press the manual test button.
Alarm
1. To ensure that the alarm level is reached,
squeeze the discharge hose (or close the
isolating valve, if fitted), and fill water into the
tank. The pump will be started via the float
switch.
2. Continue filling water into the tank until the safety
overflow switch is activated. If no external alarm
is connected to Conlift, this function can be
checked by means of a multimeter.
The safety overflow switch must be
Note
activated before the water starts running
out of Conlift.
3. Stop filling water into the tank and stop
squeezing the discharge hose. The alarm stops
(the switch opens). The pump continues
operating. When the stop level is reached, the
pump will stop.
After checking the function, push the inlet hose back
into the lifting station and let the condensate from the
boiler or air-conditioning system run into the tank
again.
