Ralph Posted April 12, 2022 Share Posted April 12, 2022 The installer for our Klargester BioFicient has let us down (long story) Basically the unit is in the ground with the pipes and power cable in the ducting and above ground waiting to be connected. I have the blower, control box and housing ready to go. Looking at the installation manual the blower housing should be sitting on a concrete plinth but the installer has put down gravel. Does anyone know how difficult it is to connect the blower and the control box and should it definitely be on a concrete plinth? Many thanks Link to comment Share on other sites More sharing options...
joe90 Posted April 12, 2022 Share Posted April 12, 2022 I self installed our plant blower etc (vortex) and it’s dead simple. I mounted my blower box on gravel, below ground to hide it and the gravel is to stop flooding the unit in case of heavy rain etc. Link to comment Share on other sites More sharing options...
JohnMo Posted April 12, 2022 Share Posted April 12, 2022 Ours is sat on a concrete slab (3x2) and half covered in soil. The soil has certainly reduced the noise (added benefit). Link to comment Share on other sites More sharing options...

Yes, a local company and the chap actually had a vortex himself. He just balanced the blower as it’s adjustable Link to comment Share on other sites More sharing options...
JohnMo Posted April 12, 2022 Share Posted April 12, 2022 I did the install, but had contractors digging the hole for treatment plant. Link to comment Share on other sites More sharing options...

Sorry for the questions but did you put in a solenoid to switch between the sludge return hose and the air diffuser? I've been told that the solenoids are more trouble than they are worth and not to use one. I'm assuming that would mean either putting both hoses on to a single manifold so they are both blowing all the time or not bothering connecting the sludge return?

The Vortex comes with a timer that switches between the two, no idea about your Klargester 🤷♂️, what does the instal manual say? Link to comment Share on other sites More sharing options...
JohnMo Posted April 12, 2022 Share Posted April 12, 2022 Sorry ours is a Harquin treatment plant and there is only one connection to the compressor. No solenoids or timers. Link to comment Share on other sites More sharing options...

The manual says to fit a solenoid, talking someone who services them and they say not to bother with the solenoid as they often go wrong, better to fit a tee piece. I think I'll give that a go. 1 Link to comment Share on other sites More sharing options...
dpmiller Posted April 13, 2022 Share Posted April 13, 2022 If a solenoid is required for the install, it should have been supplied along with the plant. Are the unit's efficiency numbers quoted with or without said valve? Link to comment Share on other sites More sharing options...
joe90 Posted April 13, 2022 Share Posted April 13, 2022 I can’t understand what this solenoid is for ? Have you got a link to the instal instructions? Link to comment Share on other sites More sharing options...

Are the unit's efficiency numbers quoted with or without said valve? The supplier basically walked off the job and took some of the equipment. I asked Kingspan what I needed and they gave me a list that did not include the solenoid. 45 minutes ago, joe90 said: I can’t understand what this solenoid is for ? Have you got a link to the instal instructions? The manual is not the best but as far as I can tell the blower comes on for 5 minutes every hour. For 4 of those minutes it blows down the 19mm diffuser hose to the main part of the tank. The solenoid is then switched and for 1 minute it blows down the 13mm sludge return system hose.

dpmiller Posted April 13, 2022 Share Posted April 13, 2022 According to the website: "3. The final settlement tank is where the excess biomass settles to form sludge. At preset intervals, portions of the sludge and liquor are returned to the primary tank for additional treatment." however excess implies there was "too much" in the previous stage chamber. Why would it need to be sent back for additional treatment unless somehow harmful to the outflow? I'd be going back to Kingspan for a WRITTEN response on this as if SEPA got wind of a non-compliant install someone could be in a world of pain... 1 Link to comment Share on other sites More sharing options...

I think I'm just going to bite the bullet and get another installer to come up and sort it out. We are moving in at the end of the month and there's a ton of stuff to do. 1 Link to comment Share on other sites More sharing options...
joe90 Posted April 13, 2022 Share Posted April 13, 2022 So yours works similar to mine, timer changes which pipe it blows down!, very poor documentation and lack of bits required (IMO), I would give them an earful. Link to comment Share on other sites More sharing options...

That’s a short “on” time? Mine is on 24/7. Discussions have taken place on timers to reduce “on” time. Thoughts anyone 🤔 Link to comment Share on other sites More sharing options...
dpmiller Posted April 13, 2022 Share Posted April 13, 2022 A settling period is good, but only if the aerator has the oomf to break through settled sludge on re-start. 5mins in the hour does sound *very* short however... 1 Link to comment Share on other sites More sharing options...
