    Traps

    From the outlet of the evap to the suction line where it goes horizontal on the roof is what distance? What tonage? Capacity control?What size  is the common suction line? Are the two evaps coils side by side to each other ? Does each evap work independently or both evaps on/off at the same time? Usually there are traps @ the evap coils and [depending] there might be an inverted trap at the roof .Usually w/ this short of a riser an oil trap is not required.
