the kind that is like the gardiner liquid logic and the one pure freedome sell.

I have these branded from yet another company.

the calibration number is the sensitivity at which the controller cuts out the pump when the flow is stopped.

I want to know what the lowest setting is you have, with which it still pumps the water up to say a 3rd storey window.

Not much help Lee but I just leave both mine on 50  seem to do the job for me 

[Lee Pryor]

I have reduced ours from 60 to 38

[Pope vader]

i have mine on 30

[Blue Frog Systems]

Im using a dial version at the moment, but my old digital i used to use on 40

CAL 25 -  .  MIKE

[spudd]

So what is the actually purpose of the CAL...??

is it to do with Sensitivity for the cut off???

[dazmond]

cal 45/flo 60.although i sometimes turn the flow down to 50 for delicate wooden windows.

think i should set the cal lower as i keep getting DE detection and the pump keeps turning on/off while this is flashing.does this mean i should turn the cal down?

[trevor perry]

i have mine set at 42 using 6mm microbore hose

[Lee Pryor]

turns out this morning that 38 was to sensitive and have increased to 42 as it was just turning on and off.

[g.brookes]

daz this is my problem, yet its happening constantly right now.  After speaking to pure freedom if it flashes de they recommend increasing the cal.  The higher the cal, the less sensitive it is to air bubbles etc

[Mike #1]

the pump should stop start in pulses with a de reading which is normal when the cal is at the right level . but most set their cal at 30 i have mine at 25 and my flo at 50 with a decent pressure and flow .

Dazmond you must go through a fair amount of water with the flo at 60 .  MIKE

38 mostly sometimes bit higher not normally more then 45 any higher then and its a first clean which i sometimes set over 50
