Thread: Fridgies??? Fixing Domestic AC unit to slab...

I always bolt mine down, but I have seen many that aren't, and I don't think that it is mandatory. Reading your instructions it says only when mounted up high.

Anything with cables going to it should be mounted firmly down.

Sure the pipework should stop it moving,but i have seen many twist around on the pipework,if you know what i mean.

We always bolt them down,or sometimes use knock ins.

Also must have corro on the orange circular cable as it has NO UV protection,which is another thing many don't do.

I'm no fridgie but it doesn't seem at all vague, nail it down.

Have a look at this page.... is a company page and 1/2 way down a unit that was insecure....

I always use Ramset nylon knock ins and stainless mudguard washers, or you can use small masonry anchors and I don't use waffle/vibration pad as we used to in the old days, most all decent modern units don't need it, they are quiet and smooth in operation.

I don't use corrugated conduit anymore for the cables including the circular 4 core flex, I most always the old style flex conduit as the corro is poor long term with UV exposure too.

Also make sure the penetrations are sealed internally and externally, stops vermin using the pipework as a highway.
Most installers don't bother doing that either, unfortunately. Mice love to make a mess inside the head unit, destroying boards and motors with urine and chewing through wires......

Geez Digger, there're just no ends to your talents are there?

I'd need a bigger radiator and a couple of fans to make one for a big fella like you... (for extra cooling you can put ice cubes in top...another top tip from "Dr Digger"....

Ben,
I always use a rubber spacer of some type with long tappets/Nylon knockins
I have lots of large rubber washers (like 80s front shock bushes but double the thickness)
Stacked waffle pad squares does the same.
You want the unit off the ground for drainage and to stop rust. I like a clear 30 mm. Most condensors these days are pressed punched and poorly painted.
Any large units cop dynabolts and strapping depending on location and height.
I consider it rough not to fix down, it's as bad as only using wall mates only to fix the head to plaster..........
