General Safety Instructions
1. Installation
General

Install the filter according to the detailed Installation Instructions provided with the filter by the manufacturer and
according to the description given in this manual.

Make sure to leave enough clearance to enable easy access for future treatments and safe maintenance
operations.

Make sure to have suitable lighting at the filter’s location to enable good visibility and safe maintenance.

Arrange suitable platforms, ladders and safety barriers to enable easy and safe access to the filter without
needing to climb on pipes and other equipment. Verify that any platform, barrier, ladder or other such equipment
is built, installed and used in accordance with the relevant local authorized standards.

Check and re-tighten all bolts during commissioning and after the first week of operation.

Use only appropriate standard tools and equipment operated by qualified operators when installing, operating
and maintaining the filter.

When installation is required in hazardous environment sitess, underground or high above ground, ensure that
the site design and the auxiliary equipment are appropriate and that installation procedures are carried out in
accordance with the relevant standards and regulations.

Ensure walking areas about the installation are slip resistant when wet.
Shipment and Transporting

Shipping and transporting the filter must be done in a safe and stable manner and in accordance with the relevant
standards and regulations.

For shipping, lifting and positioning the filter, use only approved lifting equipment, authorized employees and
contractors.
Pneumatics

Ensure that the compressed air supplied to the filter never exceeds the maximum designated pressure for the
filter. An air-pressure reduction valve should be installed on the compressed air supply line upstream of the
filter’s pneumatic inlet port.
Hydraulics
• Extra safety devices should be installed on hot water applications to avoid the danger of burns.
• The user should install a manual water cut-off valve next to the filter’s inlet port.
• In cases where the downstream piping network downstream of the filter is pressurized an additional manual water cut-off
valve should be installed next to the filter’s outlet port.
• The user should ensure that the system includes a pressure release / drainage valve to enable release of residual pressure
prior to any maintenance procedure performed on the filter.
•
The user should ensure that the filter is never exposed to water pressure exceeding the maximum designated pressure for
this filter, if needed, a pressure reduction valve should be installed upstream of the filter’s water inlet port.
• The maximum working pressure indicated on the filter’s specifications table includes the pressure caused by fluid hammer
and pressure surge effects.
Civil Engineering

Ensure that the filter installation is done by the manufacturer’s qualified technicians.

Ensure that any civil engineering work at the installation site, such as construction, lifting, welding, etc. is
performed by qualified workers / technicians / contractors and in accordance with relevant local standards.
