. The
oil Skimmer (11)
removes the top layer of oil and water from the
oil/
Water/Solids Separator (7)
and places it in the
Waste oil Decanter (12)
.
as the
Waste oil Decanter (12)
fills with the oil/water mixture, the oil will
float to the top while the water remains on the bottom. The water then moves
out of the bottom of the tank and back to the pit to be recycled again. as
the amount of oil accumulates, it will have to periodically be removed from
the
Waste oil Decanter (12)
to prevent it from building up and flowing out
of the bottom of the
Waste oil Decanter (12)
.
a. place a 5 gallon bucket below the hose on the
Oil Release Valve 4
.
b. Open the
Oil Release Valve 4
and allow oil to flow into the 5 gallon
bucket. Turn off valve when water begins flowing into the bucket.
c. Dispose of oil according to Epa Standards.

BEGin:
. The oil water separator system is now ready to operate.
2. Ensure all switches on the
Control panel (23)
are on.
3. Valve positioning:
a.
Pit Return Valve 3:
When this valve is open and the
Water Outlet Valve 2
is closed, water flows back to the pit
for continual recycling.
b.
Water Outlet Valve 2:
When this valve is open and the
Pit Return Valve 3
is closed, water flows through the
Water Outlet Valve 2
to be used as desired.
WX-OPTION:
The
Pit Return Valve 3
must be opened and the
Water Outlet Valve 2
must be closed for auto-
discharge.
4. Monitor the system closely the first few days to ensure smooth operation.
SoLiDS CoLLECTion arEa:
The solids collection area of the
Separator Tank (9)
will need to be cleaned occasionally to prevent overflow of solids
into the
Holding Tank (14).
This could be done one of two ways. In either situation, do not use pressure washers while
performing this maintenance.
. Using 2" pVC, plumb a discharge line with a shut-off valve from the solids collection area back to the
Wash Water
Catch pit (1)
, or other settling area. This will allow manual control of solids flow out of the oil water separator system,
eliminating the need to stop the unit and clean the
Separator Tank (9)
.
2. The unit will need to be stopped for cleaning purposes. Turn the
power Supply Switch (22)
to off.
a. Unplug the unit.
b. place a catch basin under the solids collection area drain.
c. Open the drain at the bottom of the solids collection area.
d. Allow water and solids to flow out of
Separator Tank (9)
.
e. Wash out the solids collection area. The
oil Coalescing Grid (10)
and baffles may be removed at this time for
more thorough cleaning.
f. When clean, reinsert the
oil Coalescing Grid (10)
and baffles if applicable.
g. plug the pump plug into the piggyback plug and then into the grounded outlet on the
Control panel (23)
.
h. plug the power supply cord into a grounded outlet. Turn on the
power Supply Switch (21)
.
i. Solids collected in the catch basin should be returned to the
Wash Water Catch pit (1)
or disposed of according
to Epa standards.

If you must store your unit in an area where the temperature may fall below 32°F/0°C, you can protect your oil water
separator system by draining all water from the system.
. Turn all switches on the
Control panel (23)
to the OFF position.
2. Unplug the unit.
3. Open the check valve near the
Sump pit (3)
and drain the water transport line. Remove the
Sump pump (4)
from
the
Sump pit (3)
.
4. Remove the drain plug from the solids collection area on the
Separator Tank (9)
and clean the tank.
5. Remove the plug from the
Waste oil Decanter (12)
and drain.
6. Remove the remaining drain plugs from the
oil/Water/Solids Separator (7)
and wipe down the
oil/Water/Solids
Separator (7)
