2-Room Outdoor Unit Combination Table
The combinations of the indoor units listed in Table 1 and 2 on the next page are combinations solely of those units which
can be operated concurrently. In addition to the combinations listed in the table, other combinations of indoor units are pos-
sible provided that the following conditions are satisfied.
Conditions:
1. At least two or more indoor units must be connected to the multi outdoor unit. It is not acceptable for only one indoor
unit to be connected.
2. The total rated cooling capacity of the indoor units to be connected must be no more than 200% of the rated cooling
capacity of the outdoor unit.
CAUTION
Example: When two indoor units are connected
If the following holds true
• Rated cooling capacity of SAP-CMRV1426EH outdoor unit: C=4 (kW)
• Rated cooling capacity of indoor units: K1, K2, ... (kW)
Then:
C x 2 (200%)
4 x 2
3.5 + 3.5
8
7
It is therefore possible to connect two units with respective capacities of 3.5 + 3.5. However, since this combination is not
found in the 2-room operation column of Table 1, operating all these units concurrently may result in trouble. At a time like
this, shut down at least one of the two indoor units to match one of the combinations found in the single-room operation col-
umn of Table 1.
NOTE
Be sure to operate the air conditioning system only when 2 or more
indoor units have been installed. If operated with only a single unit
installed, the returning fluid to the compressor may cause a malfunction.

<Combinations of Connectable Indoor Units>
In this case, all the indoor units installed must not be operated concurrently under any
circumstances. Otherwise, the air conditioner may not run properly and trouble may
occur.
