Oil Separator
All DPS(H) 003–015 units will have an oil separator on the
discharge line of the compressor. This device will remove
oil from the compressor discharge gas and return it to the
compressor suction line. The oil separator has three lines
entering it. The connection on the side of the compressor
is where the discharge gas enters. The hot gas continues
on to the Outdoor Coil from the connection on the top of the
separator. On the bottom is a small drain through which the
oil returns after separation to the compressor suction. The
refrigerant and oil path through the separator will not change
depending on Heating or Cooling Mode.

Check Valve
All DPS 003–015 will have check valves on each of the
compressor discharge lines. On medium cabinet units
(7–15 Tons), two valves, one on each compressor, prevent
recirculation of refrigerant during part load conditions. On
small cabinet units (3–6 Tons) a single check valve prevents
migration of refrigerant into the scrolls during off cycles.
