The following is a basic install of the Pioneer unit. Be sure to follow the instructions that come with any mini split package as designs can change.

A bunch of other components and assessors are included such as drain hoses, filters, and a remote control.
A nice thing about the Pioneer is the wires that go from the inside unit to the outside unit are included which some mini split kits do not include.
The inside evaporator unit needs to be mounted on the wall. This should be thought out for the best spot. Keep in mind the 16 foot line-set needs to reach the outside unit.
The bracket needs to be level and a hole needs to be drilled in the correct spot so the copper line-set and wires can go out to the outside.

The instructions will show the correct measurements that the hole needs to be drilled at.
While the instructions have the measurements for the location to drill the hole it is a good idea to temporarily mount the inside unit making sure it lines up.
The bracket can be moved if needed as long as it is on solid studs but it is simply easier to be sure the hole is correct before any drilling is done.
The line-set than slides through the hole and the unit placed on its mounting bracket.

Wiring will also run outside through the hole to the outside unit.

    I began a remodel which has gone far beyond anticipation in timeline. I purchased this exact mini split unit and just set it aside for when we’d need to install it. Turns out the line set was NOT included. You mention 3 boxes (your photo shows 2). I only had 2 boxes with my shipment like your photo. The line set was included on the invoice, the order and the product page form where I bought it. However, it was no where to be found once I opened everything up and since it’s been so long I’m not getting help to get the line set which should have been included.

    Advice? Can’t seem to find a place to just get the needed line-set, etc.

    Thank you

      The Line Set is usually included with any mini split kit but if it is not it can be bought separately. Be sure to look at the documentation for the sizes needed, one line is smaller than the other. Line sets can be bought at local HVAC supply companies or online on Amazon and other sites.

    I was thinking of mounting the condenser (outside unit) on an outer wall, instead of a cement slab on the ground. Is it extremely heavy? (The amazon link says it’s 38 or 39 pounds total…which seems impossible…but if so, the cement slab might not be necessary…) What is the weight of the inside piece and the outside piece…and is a cement slab necessary or just a solid foundation (that might be attached to the side of an outside wall)? Thanks!

    Generally speaking these two statements from the article (“The inside part called a evaporator…”, ” The outside part is called the condenser…) are incorrect for the universal systems, because in the Heat/Heating mode
    the inside part will be a condenser and outside part will be an evaporator.

    The example of correct statement: universal (cooling and heating) ductless Mini Split systems have three main components: an indoor unit, outdoor unit, and remote controller.
