Table 16: Ceiling Suspended Indoor Unit General Data.
EEV: Electronic Expansion Valve
Power wiring is field supplied and must comply with the applicable local and national codes.
This unit comes with a dry nitrogen charge.
This data is rated 0 ft above sea level, with 25 ft of refrigerant line per indoor unit and a 0 ft level
difference between outdoor and indoor units. All capacities are net with a combination ratio between
95-105%.
Cooling capacity rating obtained with air entering the indoor coil at 80ºF dry bulb (DB) and 67ºF wet
bulb (WB) and outdoor ambient conditions of 95ºF dry bulb (DB).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and outdoor
ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
1
Power Input is rated at high speed.
2
Take appropriate actions at the end of HVAC equipment life to recover, recycle, reclaim or destroy
R410A refrigerant according to applicable regulations (40 CFR Part 82, Subpart F) under section 608
of CAA.
3
Sound Pressure levels are tested in an anechoic chamber under ISO Standard 3745.
4
All communication cable to be minimum 18 AWG, 2-conductor, twisted, stranded, shielded and must
comply with applicable local and national codes. Ensure the communication cable is properly grounded
at the master outdoor unit only. Do not ground the ODU-IDU communication cable at any other point.

Table 17: Ceiling Suspended 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.
