Curious as to why every evap I've ever come across is mounted as close to the wall as possible? Makes them a PITA to clean and repair due to shelving units invariably installed directly under them.

Have to replace a medium temp evap in a walk in and plan on relocating it to an easier to service location on the ceiling.

Any feedback on this thought?

I too am redoing one that is in the corner and in about the worst place possible and wonder the same thing. I plan to move it for easier maintenance. Curious to see what others might say.
 
I try for 18” to 2’ off the wall, and blowing towards the entry door or glass doors if it has them.

Not looking at the minimum distance as that is the "rub"

Probably going for about 2' from the wall, possibly more.

12x12x8 box

Present evap has bottom rows rotted out, probably from botched attempts to clean and not get well rinsed...

1/2 half the width?
Some of my coils are 6' long.

Just joshing with ya.

Equal the height and they work and be can be easily cleaned.

Now granted, 90% of the coils I install are low profile.


Yeah, they're 6' long, but the coils are only 1/2" wide. So as long as it's at least 1/4" from the wall you should be golden!

This stuff has always confused me as well. My interpretation is that yes, if the evap is 6' long then it should be 3' from the wall. If this is correct then I dont know if I've ever seen an evaporator installed correctly, unless it was a little one fan jobbie.

Also, I've seen instructions that said they wanted the drain line pitched 4" per foot. That's a pretty extreme pitch that I always assumed was a typo. Somewhere around 1/4" per foot has always gotten the job done for me.

In a Heatcraft class it was explained the reason the drain was angled like that was so product couldn’t be packed up against the blower and cut off air flow!
 
The manual linked to says on pg 3 that 1/2 the width is for a medium profile coil. A 12x12' box will almost definitely have a low profile coil, so 1-1/2 times the height would be the correct fomula

If i remember correctly most are about 12" tall so probably 18".

That being said, probably 98% of every low profile coil i've seen is 12-14" from back wall, and I've never seen any issue other than difficult to clean.

I hate trying to access the electrical side or the txv side on top of shelving stacked with product! It would be so nice to not have to bend my body in half and work in a half reclined position on an icy shelf looking through my bifocals sideways.

The only way I’ve seen this is when the evaps are 30’ in the air.

Especially when the tray of Chocolate covered strawberries in in the way!
