Aerjec Installation Advive Please?

[Markw996]

Hi,

I am planning to fit an Aerjec air separator to my central heating this weekend, could somebody please check my system and tell me if I have understood the installation instructions correctly?

Here is my new Aerjec and my proposed piping and connections:



Here is my CH system showing the H section I propose to cut out and my connections:



Thanks,
Mark

Why do you want to fit a sludge catcher, sorry airjec?, btw there is no need for that 15mm bypass from the pump flow to the return.

Agree,just re fit the tee pieces so they are touching with no pipe work showing,so cold feed and vent are as close as possible and will not need and as said,do away with by pass
imho

Long story but I have air problems and would like to both fix them and stop them coming back, so the air separator will get fitted now I've already bought it! The 15mm bypass at the bottom of the photo is going to be converted to 22mm and I have a Honeywell Auto Bypass valve to install in it.

Sorry, I don't understand what you mean, you are talking about the bypass at the bottom of the photo right?

Thanks,
Mark.

Doh.. Sorry.. I understand what you mean now!

Although Airjecs seem to be held in the same regard as Marmite, do my connections look correct as it's going to be an afternoons work to fit the thing and I'd like to be sure I'm not going to have to cut it out and refit it due to a silly mistake!

Thanks,
Mark.

Hi Mark, just follow the instructions with the airjec, its easy to say this from the comfort of my armchair, 100miles away,without even looking at it..... but Il bet you that fitting the airjec doesnt fix your "air" problem. either way
let us know how you get on mate

Return the autobypass to the merchants, you do not need one with a y plan, an s plan when both 2 ports can be shut you do ,but a 3 port will be "open" to either the cylinder coil, the radiators or both at any one time.

Ok, maybe you could give me some pointers?

1) When my pump starts up it sounds really loud with water swirling around inside all the pipes in the airing cupbard.
2) The pump ticks all the time it is running, fairly regular but not mechanical as it is not rythmic.
3) When the boiler/pump clicks off sometimes I get a quick spurt of water into the F&e tank.

This all happens whether hot or cold, worse when hot, but the noise wakes me up in the morning so it obviously quite bad when cold too.

It seemed to be pointing to a blockage in the cold feed, probably around the vent / feed H arrangement, hence I want to cut it out and might as well replace it with an aerjec just for good measure.

Does that sound a reasonable conclusion to draw?

Thanks,
Mark.

Yes mate spot on, well worth a try then . let us know what you find.

Yes your proposed connections are correct, and I would also look to extend pipe A (vent) a bit higher over the tank and then back down making sure it does not drop into tank to far,

Good subject matter and sorted what I was looking for with ref to the myson Aerjec I found at a customers house. Thought I'd pop this link in for the different piping configurations that you might come across. By-pass, Pressure Reducing Valves & Thermostats<br>Condensate Pump & Fittings

The arrangement shown in the right-hand option is not approved by the manufacturers. To work as intended, the device needs the cylinder on its side with the vent pipe at the top, as in the left and centre options.
