Remove the foam depressurization pad from from the top of the unit. Pour clean water in to the depressuriza-
tion chamber until it flows from the outlet drain port of Tower #2. Confirm that there are not any obstructions
with the drain line and the unit is draining properly. During initial filling, dust may rise from the carbon elements;
this is only displaced air and is entirely harmless. ZEKS recommends that carbon elements should be pre-
soaked for 24 hrs. Any carbon dust in the outlet water is harmless. Replace the foam depressurization pad.
Using normal lifting precautions, replace the white Absorption Element in to Tower #1. Push the element com-
pletely to the bottom of the tower. Replace the lid to Tower #1.
7.3 INITIAL START-UP AND MONITORING
ZEKS recommends a daily check on the quality of the discharged condensate from the oil/water separator for
the first week of operation. Using the Test bottle provided with the unit, take a sample of condensate from the
TEST port on Tower #2. Fill the bottle as much as possible. The condensate collected should be clear when
viewed through the container. Particulate concentration less than 20ppm is not visible with the human eye.
Therefore, if the condensate appears cloudy, the oil carryover is greater than 20ppm. Within a week of opera-
tion, the quality of the condensate should improve. Clean the collection bottle and return it to the holder located
on top of the OS Oil/Water Separator.
8. SCHEDULED MAINTENANCE
8.1 REPLACEMENT OF ELEMENTS:
Under normal operating conditions, ZEKS recommends that the Absorption Element and the Carbon Finishing
Element(s) be replaced simultaneously on a yearly basis. Excessive oil by-pass from the compressed air sys-
tem will result in shortened element life. Test the quality of the condensate discharge to determine element
effectiveness (Reference Section 7.3).
ABSORPTION ELEMENT (TOWER #1)
Lift the saturated element from Tower #1 using standard heavy lifting precautions. Use caution when lifting
the saturated element from the tower as element will be heavy from retained oil. Allow the element to drain
off excess condensate prior to completely lifting from the tower. Place the saturated element in to a plastic
bag or bucket to allow element to safely continue to drain. Place the new Absorption Element in Tower #1
and push the element completely to the bottom of the tower. Replace the lid to Tower #1. Pour collect con-
densate from the Absorption Element in to Tower #1. This will ensure that the separation process of the col-
lected condensate is completed prior to disposal.
REPLACEMENT OF CARBON FINISHING ELEMENT
(TOWER #2) AND (TOWER #3 - OS2501 MODEL ONLY)
To prevent dusting, clean water can be poured over the Carbon Finishing Element. Carbon dusting is com-
pletely normal with a new element and is completely harmless.
Remove lid from Tower #2. Carefully lift the saturated Carbon Finishing Element from Tower #2 using stan-
dard heavy lifting precautions. Allowing the element to drain off excess condensate prior to completely lift-
ing from the tower. Place the saturated element in to a plastic bag or bucket to allow element to safely con-
tinue to drain. Place the new Carbon Finishing Element in Tower #2 and push the element completely to
the bottom of the tower. Ensure that the top of the element is below the drain outlet hole. Clean water can
be
Replace lid to Tower #2. Pour collected condensate from Carbon Finishing Element in to Tower #1. This
will ensure that the separation process of the collected condensate is completed prior to the condensate
exiting the unit.

All used elements must be properly disposed of in accordance with current regulations
for the disposal of hazardous waste in your area.
