*Evaporator coil fins/condenser coil fins.
†Weight of 14-in. roof curb.
**Requires the accessory controls upgrade kit.
††Circuit 1 consists of lower portion of both the condenser and evaporator coils, and
Circuit 2 consists of the upper portion of both coils.
\The 559F300 units require 2-in. industrial-grade filters capable of handling face ve-
locities up to 625 ft/min (such as American Air Filter no. 5700 or equivalent).
NOTE: The 036-150 units have a loss-of-charge/low-pressure switch (accessory or op-
tion) located in the liquid line. The 180-300 units have a low-pressure switch (standard)
located on the suction side.
