Can you disassemble MVHR unit to transfer through loft hatch

[I N]

Like the title says - can a unit like Zehnder Q350 be disassembled and re-assembled easily?

I'd like to install it in boarded loft space. Loft hatch is 700x700, unit is 850x720x570, I can't really make loft hatch bigger and I can't make a temporary hole in ceiling elsewhere due to joint spacing. 

My only option is to disassemble it, move it to loft in parts and then reassemble. 

Any ideas?

Is there a stop bead around the hatch (like a door stop?)

 

You only need an extra 20mm.

 

Otherwise I would be removing the loft hatch surround and while doing it, probably enlarging the hole and enlarging at least one dimension.

You don't need much off it for it to fit  either square or diagonally. Is there an easy bit such as a housing, or feet?

Thanks its a good idea and if it was a just a case enlarging the loft hatch I'd do it tomorrow :-). Trouble is the loft hatch is off centre to roof space and there is a purlin just above it. Even if I can squeeze it through the hatch by width, it needs to be 500mm deep to clear purlin. So I need to somehow get it to 700x500 pieces to get it up there :-).

Its disassemble + reassemble (if thats even possible) or choose something different.

The limiting factor will be the frame the covers are attached to which is unlikely to be simply bolted together. You need the maintenance manual for it or some pictures with the covers off.

Not convinced it’ll be possible to do. It’s also very slightly bigger according to the dimensions in this manual.

750 x 650 x 560. 
 

I fit these on every single one of my M&E projects. Excellent results and reasonably priced for what they offer / how they perform.

There you go, don't enlarge the loft hatch, choose a smaller unit.  Job done.

Thank you so much :-). This is perfect. I have actually asked CVC for a quote so I'll direct them to this unit. 

I have been trying to find a unit that fits too - the only unit I could find was Vent Axia but they were really difficult with giving me a quote which made me a bit reluctant to use them.
