Notes:
1.The current value of combination unit is the total value of each basic model(refer to Table.7-3)
For example: 34HP=10HP+12HP*2
Power current: MCA=14.5+21*2=56.5
TOCA=18.6+20.9*2=60.4
MFA=20+25*2=70
Compressor: RLA=17.4+17.4*2=52.2
2. RLA is based on the following conditions, Indoor temp. 27°C DB/19°C WB, Outdoor temp. 35°C DB
3. TOCA means the total value of each OC set.
4. MSC means the Max. current during the starting of compressor.
5. Voltage range units are suitable for use on electrical systems where voltage supplied to unit terminals
is not below or above listed range limits.
6. Maximum allowable voltage variation between phase is 2%
7. Selection wire size based on the larger value of MCA or TOCA
8. MFA is used to select the circuit breaker and the ground fault circuit interrupter (earth circuit breaker).
Remark:
MCA: Min. Current Amps. (A)
MFA: Max. Fuse Amps. (A)
RLA: Rated Locked Amps. (A)
FLA: Full Load Amps. (A)
TOCA: Total Over-current Amps. (A)
MSC: Max. Starting Amps. (A)
OFM:Outdoor Fan Motor.
KW: Rated Motor Output (KW)
