GENERAL DATA
Table 3: Single-Zone LGRED Four-Way 3 x 3 Ceiling Cassette System General Data.
EEV: Electronic Expansion Valve, IDU: Indoor Unit, ODU: Outdoor Unit. Unit comes with a dry helium
charge.
This data is rated 0 ft above sea level, with 24.6 ft of refrigerant line per indoor unit and a 0 ft level
difference between outdoor and indoor units.
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) and 75ºF wet bulb (WB).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and 60ºF wet bulb
(WB); and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
1
Power Input is rated at high speed.
2
Power wiring to the ODU is field supplied, solid or stranded, and must comply with the applicable local
and national codes.
3
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.
4
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
5
All power wiring/communication cables from ODU to IDU are field supplied and are to be minimum 14
AWG, 4-conductor, stranded, shielded or unshielded (if shielded, must be grounded to chassis at ODU
only), and must comply with applicable local and national codes.
6
Piping lengths are equivalent.
7
Cooling range can be extended from 5°F down to -4°F using the Low Ambient Wind Baffle Kit (sold
separately).
