Instruction book 8. All regulating and safety devices shall be maintained with due care to ensure that they function properly. They may not be put out of action. 9. Before clearing the device for use after maintenance or repair, check that operating pressures, temperatures and time settings are correct.
Technical data). OSC 35 up to OSC 145 have two towers and are called two-step units. OSC 355 up to OSC 1200 have three towers and are called three-step units. OSC 2400 have six towers. They consist of two three-step units.

The condensate flows to the first tower and seeps through an oleophilic filter (4), which absorbs most of the oil.

Instruction book The water from the first tower, still containing a small quantity of oil, gradually flows to a second tower (9), where two filters are fitted: a small oleophilic filter, which absorbs some more oil from the condensate, and an activated carbon filter (7).

Instruction book Reference Description Condensate outlet Tower 1 Tower 3 Tower 2 Diffuser Condensate outlet (test) Protector Housing part 1 Housing part 2 Procedure 1. Install the OSC on a level floor, suitable for taking its weight. Keep in mind to reserve sufficient free space for replacement of the filters (see section Maintenance). 2.
Procedure OSC 35 up to OSC 145: 1. Remove the lid of the first tower. Take out the oleophilic filter. 2. Remove the lid of the second tower and take out the activated carbon filter. Remove the plastic bag and put the filter back.
Instruction book Maintenance Maintenance Check the filters regularly as explained below in order to prevent untreated condensate from entering the sewer. Sample the condensate weekly. If the filters are not installed properly, oil-containing condensate can leave the OSC. • • When new activated carbon filters are placed, the outgoing water may initially look black (caused by carbon dust).

2. Remove the lid of the first tower and take out the oleophilic filter (4 - Flow diagram of OSC 35 up to OSC 145). On OSC 355 up to OSC 1200, remove also the lid of the second tower and remove also the small oleophilic filter (6 - View of OSC 355).
