This data is rated 0 ft. above sea level, with 25 ft. of refrigerant piping per coil.
Main Coil Cooling Capacity Rating obtained with entering air of 95°F D.B. / 75°F W.B. and
leaving air of 52.9°F D.B. / 52.5°F W.B.
Main Coil Heating Capacity Rating obtained with entering air of 44°F D.B. and leaving air
of 70°F D.B.
Reheat Coil Heating Capacity Rating obtained with entering air of 54°F D.B. and leaving
air of 75°F D.B.
Actual discharge air temperatures may vary from discharge air temperature set-point due to changes in outdoor air processing loads.

Take appropriate actions at the end of HVAC equipment life to recover, recycle, reclaim or
1
destroy R410A refrigerant according to applicable regulations (40 CFR Part 82, Subpart F)
under section 608 of CAA.
Sound power levels are tested under AHRI 260 Standard.
2
All communication cable from the outdoor unit to the DOAS unit is to be minimum 18 AWG,
3
2 (2 conductor), twisted, stranded, shielded and must comply with applicable local and na-
tional codes. Ensure the communication cable is properly grounded at the outdoor unit only.
Do not ground the outdoor unit -DOAS unit communication cable at any other point.
4
10°F entering air temperature is allowed for 1,500 CFM or less with minimum 12-ton out-
door unit for one (1) DOAS connected to one (1) outdoor unit, and minimum 30-ton outdoor
unit for two (2) DOAS units connected to (1) outdoor unit. Maximum number of two (2)
DOAS units may be connected to one (1) outdoor unit with 10°F entering air temperature.
Both the ARND153DCR4 and the ARND203DCR4 can provide CFM as low as 900 CFM.
5
For a 900 CFM application, the unit requires a 1-to-1 combination with an LG MV 5 Heat
Recovery 6-ton or 8-ton outdoor unit.
