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
WOS water oil separators are intended for separating lubricant oil from
condensate from 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.
Advanced dimensioning
For advanced dimensioning please use following equations
( )[]=m(Max oil adsorption)[g]
FAD(compressor)Nm
hc(oil carryover)󰇣g
Nm󰇤
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
·It is recommended to place the device near the wall. Test valve is located on front
side of the device.
·Make sure that you have easy access to the front side of the device.
·Take both bags (carbon and polypropylene) out and remove protection foil from both
filter bags. Then put the cartridge back in the device.
·Make sure that white filter element is inserted in chamber 1 and carbon filter
element is inserted in chamber 2.
·Fill the device with clean water!
·Connect device to the system.
·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.

WOS - Installation and operating manual

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
·Oil concentration in outlet reaches concentration determined with local directives
and laws.
[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.
·Damaged components are to be replaced by new ones. If a marked degree of
damage is found, the entire vessel is to be replaced.
·Carry out a check for leaks once the maintenance work has been finished.
Warning
Disposal of used filter elements must be carried out in accordance with local regulations
and laws.
Warranty exclusion
The guarantee shall be void if:
·The operating instructions were not followed with respect to initial commissioning
and maintenance.
·The unit was not operated properly and appropriately.
·The unit was operated when it was clearly defective.
·Non-original spare parts or replacement parts were used.
·The unit was not operated within the permissible technical parameters.
·Unauthorised constructional changes were made to the unit or if parts of the unit
that may not be opened were dismantled.
