Notes:
1. Nominal cooling capacities are based on the following conditions:
Indoor temp: 27°CDB, 19°CWB;

Outdoor temp: 35°CDB;
Equivalent ref. Piping: 8m(horizontal)
2. Nominal heating capacities are based on the following conditions:
Indoor temp: 20°CDB;
Outdoor temp: 7°CDB, 6°CWB;
Equivalent ref. Piping: 8m(horizontal)
8. Actual noise level may differ, depending on the room structure, etc, since these noise values are from an anechoic room.

4.Indoor unit combination:
Caution on combination
The one-drive-four outdoor unit M4OA-27HRIN1 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 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 one 18k indoor unit(either cassette or duct), and other indoor
unit should be all 7k;
4. There should be no more two duct indoor units, and other indoor units should be all wall
mounted;
5. There should be no more one cassette;
6. Cassette and duct can not be installed simultaneously.
7. When heating, capacity attenuate sharply if indoor unit capacity exceed too much.
