    Notes

    • Different models of all available matching indoor units can be combined in any order to create a multi zone split system, up to a quantity of the number of available circuits.
    • Not all available circuits need to be utilized with an attached indoor unit. 66% or higher of the total capacity utilization is recommended.
    • Every indoor unit attached to a multi zone system will operate at a random, self-regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity) or turn OFF as needed.
    • Outdoor unit will also self-regulate its total output capacity, based on the total demand it reads from all the simultaneously running indoor units at any given moment, up to its maximum rating capacity.
    • With multi split systems, the total demand from the outdoor unit, will seldomly exceed 75% of the total available capacity of the combined indoor unit group due to load fluctuations of each indoor unit.
    • Therefore, total attached indoor unit capacity can be selected up to 133% of the supporting outdoor unit's rated capacity.
    • Although very seldom, if the total demand from the combined group of indoor units' exceeds the rated capacity of the outdoor unit, the capacity of the each indoor unit will be annotated accordingly.
    • For high demand applications, max loading limits may need to be reduced up to 20% to avoid underperformance risks during some extreme conditions.

        I’d buy it again
        Size: 22"×15", Color: Black
        It’s a nice little printer stand, able to hold 2 decent-size printers in a small space. Assembly was fairly easy with extra screws and dowels included. The only thing that is weird is that each shelf is two pieces and they have to be attached together with dowels and then supported on the edges with metal bars. All of the metal support bars are also two pieces and have to be attached together before attaching to the shelves. The only reason I can see for this is so they can use smaller shipping boxes. But once it’s assembled it feels sturdy enough.

        It had the features I wanted at a reasonable price
        Size: 22"×15", Color: Black
        I needed a new printer stand and I looked at many before I chose this one. I liked the size of it for my apartment and that it had shelves for additional storage. I was able to put it together without difficulty. It is sturdy and was a good price. A plus was the power outlet and that you could add wheels or make it stationary. It goes well with my computer desk.
