If you haven’t bought the mini split yet lookup a mini split with a ceiling cassette. They look nicer and go in the ceiling and look like a fan. They fit in between 24” on center trusses.

Unfortunately already bought.
And cassette not available right now.

Keep the outside unit out of direct sun

Hmm... Googled it. It does not really needed. And I dont know why, but very few days I really need ac in workshop. I dont know why my house is hot, but workshop cool.

Primary purpose of this unit is heating.
For snow I will by silicate large bricks and will make 2ft high pedestal.

 

There’s not much of a code for these that I’ve heard of. Maybe the electric load. Follow install instructions, if it’s a shop consider dust. They have coils and filter screens on the inside unit. The inside unit needs a condensation drain. Keep the outside unit out of direct sun, fairly dry area, not in a position to get covered in snow and ice.

 

Yes, DIY. Currently its not available, and I don't know how long to wait. It can be next month and can be next year.

Frames to low, less than 2ft and
Wall with plastic siding and it hard to find studs from outside. 24K unit weight a lot.
And for price of frame I will buy 14 bags of concrete.

 

Lol, yea but lifting that concrete sucks.

More to the point, you need an area below the heat pump for ice to accumulate, but not impede drainage condensate. It won't be easy to shovel, depending on how much it's used and how much snow you get.

 

Have to get the unit up off the ground, or concrete surface. It needs space to drain and a gap so snow accumulation can’t get to it.
As to why, snow and frozen runoff is very costly to a heat pump during winter. I’ve had minis and VRF units not properly elevated spring leaks in the bottom of the outdoor coil from ice damming causing the ice to build back on the coil and squeeze the passes until they crack.
The unit HAS TO be elevated off the ground/surface.

 

This how I raised 12K units at home
Next unit will be on gray 8x8x16" bricks.
This one actually have 15 bags concrete foundation, I made very big hole in ground

 

I'm not a fan of your anchoring system but that'll mostly do. Concrete block will work but it's less then ideal since the block on one side does block some of the drainage. I've had a few people here do that in seasonal occupation settings but never year round primary heating.

Is this along either coast? Or are you much more in land? The Vancouver area and most of the maritimes won't be cold enough to matter most of the year. Inland is a different story.

 

Not east cost, great lakes. This winter, one night temperature was -34. Celsius, but farenheit almost the same.

I will install bricks only on sides and leave middle open for drainage

 

Yea it looked like cottage country from the trees. I don't recall - 34°C this past winter but maybe you're way north. Windchill doesn't count when you're selecting equipment. Most equipment you'll need to use a bypass on the outdoor sensor. (my suppliers will include it but I have no idea what you'll get with DIY) Without the bypass Mitsubishi and fujitsu will shutoff under 25°C. I don't remember if daikin does the same. Flip a coin for all of the no name companies.

 

Don’t like the unit setting on blocks. This is a better solution.

 

As the OP already mentioned, he is not comfortable using wall brackets. (even though I would in his situation)

PS. That's way too close to the wall for a heat pump in a cold climate. Too close for a hot environment. Electrical is missing box connectors. Hope that's just some random image you've found online.

 

unfortunatly wall is close to electric panel and stud finder shows spark symbol everywhere.
I will better make concrete pedestal.

 

So you want to use the wall immediately behind the panel? Logical place, but not the easiest. Anyways, you'll still want to make sure that you don't block any of the ports on the bottom, most importantly on the coil end.
