4.2 Finishing Up
1. Once the oils have been removed from the tank
being skimmed, disconnect the intake hose from
the intake attachment via the quick connection.
2. Before shutting off the pump, lift the intake hose
out of the tank for about 10 seconds. This will
ensure that no liquid is still in the intake line.
3. Shut the pump off by adjusting the regulator.
NOTE: See Section 4.3 for details on empty-
ing the tank, if necessary, before proceeding
further.
4. Disconnect your air line from the air intake t-
ting.
5. Remove the return line from the tank being
skimmed by lifting it near its connection to the
coalescing tank to free it of liquid.
4.3 Emptying the Coalescing Tank
1. Open waste water ball valve to manually drain
any wastewater to your waste container, then
close (refer to ow schematic in Section 3.2).
2. Tilt, in an upward position, the prelter and ultra-
lter housings.
3. Close ball valve for the oil ultraltration line (refer
to ow schematic in Section 3.2).
4. Open ball valve for oils to be emptied from tank
(refer to ow schematic in Section 3.2).
5. Place the oil return line into your preferred oil
holding vessel. Make sure that it can hold the re-
maining amount of oil left in the coalescing tank.
CAUTION: Fluid is returned under pressure.
6. Adjust the air regulator of the pump to 10psi.
4.4 Storing the System
It is recommended to empty the coalescing tank before
storing the system for more than 1 or 2 days. Holding liq-
uid in the tank can contribute to bacterial contamination
of the coalescer, and thus your equipment. We recom-
mend utilizing an Oxygenator™ when storing uids in
the coalescing tank to minimize bacterial growth.
4.5 Cleaning the System
1. Empty and clear the coalescing tank and both
hoses of all uids (refer to Section 4.3)
2. Discard the cellulose ultralter.
3. Mix a 10% solution of a mild degreasing agent,
such as Red Thunder™, provided, to clean the
coalescing tank and stainless steel prelter. A
pressure washer works well, or just clean by
hand with the brush, provided.
4. Rinse thoroughly with straight water.
5. Dispose of wash and rinse baths in accordance
to federal, state, and local environmental laws
and regulations.
6. Replace lters, making sure o-rings are free of
debris and seated correctly.
7. Double-check all hoses, ttings, and attach-
ments for cracks and obstructions.
