Safety instructions
The relevant safety at work and accident prevention regulations, plus operating instructions, shall apply
for operating the filter. The filter has been constructed in accordance with the generally recognized
rules of engineering. It complies with the requirements of directive 2014/68/EU concerning pressure
equipment.
Ensure that installation complies with local laws for operation and routine testing of pressure
equipment at the place of installation.
Operator/user of the filter 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 exceed max. operating pressure or operating temperature range (see data label).
The permissible working temperatures and pressures for ad-on parts and filter elements
are given under Technical data for those ad-ons. Maximum temperature and pressure for
assembled system is the lowest of any individual part.
It is necessary to ensure that the unit is equipped with the corresponding safety and test
devices to prevent the permissible operating parameters from being exceeded.
Filter has been designed for a primarily static pressure. Rapid changes of pressure are not
allowed.
The medium used may not have any corrosive components that could attack the
materials of the filter in a way that is not permitted. Do not use the filter in hazardous
areas with potentially explosive atmospheres.
All installation and maintenance work on the filter may only be carried out by trained and
experienced specialists.
It is forbidden to carry out any kind of work on the filter and piping, including welding and
constructional changes, etc.
A pressure gauge, which shows the operational pressure, must be installed in the unit,
respectively in the pipeline.
Depressurize the system before carrying out the installation work. The unit must be
installed vertically in the piping.
Ensure that filter is installed without any stresses.
Use original spare parts only.
Use the device for appropriate purpose only.
There shouldn’t be any tension between filter and installation. Filter shouldn’t be subject
to any stress, vibration or other influence that could cause damage to the unit.
