Safety instructions
The relevant safety at work and accident prevention regulations, plus operating instructions,
shall apply for operating the separator. The separator has been constructed in accordance
with the generally recognized rules of engineering.
Ensure that installation complies with local laws and directives.
Operator/user of the separator should make himself familiar with the function, installation
and start-up of the unit. All the safety information is always intended to ensure your
personal safety.
Do not apply pressure to the separator.
The permissible working temperatures and pressures for ad-on parts and separator
elements are given under “Technical data sheet” and “Installation and operating
manual”for those ad-ons. Maximum temperature and pressure for assembled
system is the lowest of any individual part.
The medium used may not have any corrosive components that could attack the
materials of the separator in a way that is not permitted. Do not use the separator in
hazardous areas with potentially explosive atmospheres.
All installation and maintenance work on the separator may only be carried out by
trained and experienced specialists.
It is forbidden to carry out any kind of work on the separator and piping, including
welding and constructional changes, etc.
Depressurize the system before carrying out the installation work.
Use original spare parts only.
Use the device for appropriate purpose only.
There shouldn’t be any tension between separator and installation. Separator
shouldn’t be subject to any stress, vibration or other influence that could cause
damage to the unit.

Appropriate use
WOSm water oil separators are intended for separation of lubricant oil from
condensate generated in compressed air systems. This appliance must be used
only for the purpose for which it was specifically designed. All other uses are to be
considered incorrect.
The manufacturer cannot be held responsible for any damage resulting from improper,
incorrect or unreasonable use.
Use genuine spare parts only. Any damage or malfunction caused by the use of ungenuine
parts is not covered by Warranty or Product Liability.

Oil carry over (c) can be determined by measuring oil volume at two sequential compressor
services. In order to determine oil carry over compare initial volume of new oil with volume
of oil drained out of compressor at oil replacement. It is recommended to keep a record of
compressor services. When oil carry over is not known we suggest to use c(oil
carryover)=0,005g/Nm3.

Installation
Unpack the device
Fill the filter element with clean water!
WOSm separator is optimized for mounting on the wall and therefore wall mounting
bracket is included. (wall mounting screws are not included)
Make sure that you have easy access to the device and that there is enough space to
unscrew and remove filter element.
Fix the cyclonic chamber to wall mounting bracket (4 screws M4x10 DIN912 are
included).
Change the housing O-ring.
Remove plastic cap from the filter element and tighten cartridge to the cyclonic
chamber (make sure that o-rings are in appropriate position).
Connect device to the system. At least 10% outlet pipe/hose slope recommended.
Trapped air prevents condensate to flow into or out of the WOSm separator. During
installation ensure that no water pockets are formed in the inlet/outlet pipe/hose.
Outlet must be connected to the sewage system.
Warning
It is strongly recommended to fill the device with clean water at least 24h (we recommend
to fill water into cartridge 1 day before installation/service) before you start to drain
condensate into the separator. If you start to drain condensate into an empty device, filter
element can get saturated instantly or efficiency may be decreased.

Maintenance
It is recommended, that you do a check once per week to evaluate filter element saturation.
To test water quality use test set. Instructions are attached in test set. Filter element must
be replaced when first of the following parameters appears:
4000 operating hours of compressor[3]
12 months regardless compressor operating hours
All polypropylene filling that is normally white becomes yellow due to adsorbed oil.
During operation coloured area (adsorbed oil) spreads from top of the cartridge to
the bottom.
[3] At compressor oil carry over 2,5mg/m3. Lower/higher oil carry over means proportionally longer/shorter lifetime (e.g. if
oil carryover is 5mg/m3lifetime reduces to 2000 operating hours).
Water quality can also be checked with “oil indicating test paper”. For test set please contact us or your local distributor.
To replace filter element follow this steps:
Remove plastic cap from NEW filter element, fill the cartridge with clean water and
close it back with plastic cap. (Please pay attention to warning specified in
INSTALLATION chapter)
The housing O-ring should also be changed at the same time the filter is changed.
Close condensate inlet or make sure condensate will not be discharged into WOSm
during service.
Unscrew saturated filter element and seal it with enclosed plastic cap.
Clean connection for filter element on cyclonic depressurization chamber.
If necessary clean interior of cyclonic chamber.
Remove plastic cap from NEW filter element and save it for next filter change.
Tighten NEW filter element to cyclonic chamber
Replace old coalescing filter on cyclonic chamber with NEW one.
Open inlet connection and put the unit in the operation.
Warning
Disposal of used filter elements must be carried out in accordance with local regulations
and laws.
