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.

3 Communication cable from the outdoor unit to the DOAS unit to be minimum 18 AWG,
4-conductor, twisted, stranded, shielded and must comply with applicable local and nation-
al codes. Ensure the communication cable is properly grounded at the outdoor unit only.
Do not ground the outdoor unit - DOAS communication cable at any other point.
