4.Indoor unit combination:
Caution on combination
The one-drive-four outdoor unit SMF-4E27AI nominal cooling capacity is 8kw(under condition of ambient temp. 35℃db/24℃wb, indoor temp. 27℃db/19℃wb). According to refrigeration design criterion, total indoor unit capacity should be equal to outdoor capacity, otherwise, we can not guarantee best performance and safe operation. Although, we made special design on refrigeration system regarding customer’s requirements. Based on this, when indoor total capacity exceed outdoor capacity, the machine can still run. Under this condition, the single indoor unit capacity will attenuate. That means you can not gain the nominal capacity, but smaller than it. We are out of responsibility if customers don’t follow the notice below:
1.You can connect two, three or four indoor units according to your need;
2.The total indoor unit nominal capacity should not exceed 11.3kw(42% more than nominal capacity);
3.There should be no more than one 18k (either cassette or duct) indoor unit when four indoor units are connected, and other indoor unit should be all 7k;
4.When three or four indoor units are connected, there should be no more than one cassette. If the cassette is present, the other duct should be all 7K
5.There is no limit to two indoor units combination.
6.When heating, capacity attenuate sharply if indoor unit capacity exceed too much.
