1-2-1. Method for obtaining system cooling and heating capacity:
To obtain the system cooling and heating capacity and the electrical characteristics of the outdoor unit, first add up
the ratings of all the indoor units connected to the outdoor unit (see table below), and then use this total to find the
standard capacity with the help of the tables on 1-4. STANDARD CAPACITY DIAGRAM.

(2) Sample calculation
1 System assembled from indoor and outdoor unit (in this example the total capacity of the indoor units is greater than that of
the outdoor unit)
• Outdoor unit MXZ-5C42NAHZ
• Indoor unit MSZ-GE09NA × 2 + MSZ-FH15NA ×2
2 According to the conditions in 1, the total capacity of the indoor unit will be: 9.0 × 2 + 15.0 × 2 = 48.0
3 The following figures are obtained from the 16.8 total capacity of indoor units, referring the standard capacity diagram in "4-3-3. MXZ-5C42NAHZ <cooling>" and "4-3-4. MXZ-5C42NAHZ <heating>". Capacity (kBTU/h)

(1) The capacity of each indoor unit (kW) = the capacity A (or B ) X
model capacity
total model capacity of all indoor units
(2) Sample calculation (using the system described above in 4-1-1. (2) ):
During heating:
During cooling:
• The total model capacity of the indoor unit is:
9.0 × 2 + 15.0 × 2 = 48.0 kBTU/h
Therefore, the capacity of MSZ-GE09NA and
MSZ-FH15NA will be calculated as follows by
using the formula in 4-1-2. (1):
9.0
= 7.88 kBTU/h
48.0
15.0
Model 15 = 42.0 ×
= 13.13 kBTU/h
48.0
Model 09 = 42.0 ×
• The total model capacity of indoor unit is:
10.9 × 2 + 18.0 × 2 = 57.8 kBTU/h
Therefore, the capacity of MSZ-GE09NA and MSZFH15NA will be calculated as follows by using the
formula in 4-1-2. (1):
10.9
Model 25 = 48.0 × 57.8= 9.05 kBTU/h
18.0
Model 50 = 48.0 × 57.8 = 14.95 kBTU/h

NOTES:
1.Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.
2.Self-diagnosis function
The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch
(SW1) and LED1, LED2 (LED indication) found on the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.
! WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2
minutes (input voltage: 230 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then
wait for at least 1 minute.
• Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual.
Do not replace the outdoor board without checking.
Cautions when servicing
• Use copper supply wires.

The pipe connection size differs according to the type and capacity of
indoor units. Match the piping connection size of branch box with indoor
unit.
If the piping connection size of branch box does not match the piping
connection size of indoor unit, use optional different-diameter (deformed)
joints to the branch box side. (Connect deformed joint directly to the
branch box side.)

8. CAPACITY CORRECTION CURVE BY REFRIGERANT PIPING LENGTH
MXZ-4C36NAHZMXZ-5C42NAHZMXZ-8C48NAHZ
(1) During cooling, obtain the ratio (and the equivalent piping length) of the outdoor units rated capacity and
the total in-use indoor capacity, and find the capacity ratio corresponding to the standard piping length from
Figure 3. Then multiply by the cooling capacity from Figure 1 to obtain the actual capacity.
(2) During heating, find the equivalent piping length, and find the capacity ratio corresponding to standard piping
length from Figure 3. Then multiply by the heating capacity from Figure 2 to obtain the actual capacity.
