Table 16: Two-Way Ceiling Cassette Indoor Unit Electrical Data.
MCA : Minimum Circuit Ampacity.
MOP : Maximum Overcurrent Protection.
Units are suitable for use on an electrical system where voltage supplied to unit terminals is within the listed range limits.
Select wire size based on the larger MCA value.
Instead of fuse, use the circuit breaker.
EEV: Electronic Expansion Valve
Power wiring is field supplied and must comply with the applicable local and national codes. See below
for detailed electrical data.
This unit comes with a dry nitrogen charge.
All capacities are net with a combination ratio between 95-105%.
