ALF 30-S ALF 30-R ALF 30-P

ALF 40-R ALF 40-P

ALF 50-R

ALF 60-R

ALF 80-R

Always use approved and certified equipment for the lifting. Refer to dimensional

drawing for the specific ALF filter for the weight of the equipment.

When lifting a filter, then use proper and approved rope slings and make sure

that the filter is prevented from tilting or rotating. Center of gravity is stated on the

dimensional drawing.

The ALF filter must be empty during lifting or transportation in order to avoid

unstable lifts and damage to the ALF filter.

WARNING

Always use lifting slings

with appropriate strength and dimension to handle the

weight of the ALF Filter

Always lift the ALF

filter by the lifting points, as shown above

Make sure that the ALF filter is empty before lifting.

4.4 Foundation

The ALF filters that are equipped with support feet or mounting brackets must be

fastened securely to the floor or a steel structure.

The maximum static foundation load calculation can be purchased on a

foundation drawing on request.

It is important that the foundation is made so that the filter is installed in

completely horizontal or vertical position to ensure correct fitting of piping

In vibrating environments or upon installation in earthquake zones loads on

nozzles and foundation bolting should be considered carefully prior to installation.

2. Proper Pipe Support shall be considered for the flushing pipe line. Otherwise due

to the high velocity, flushing pipe will be damaged. Suitable support shall be

considered for filter types ALF 30, ALF 40, ALF 50, ALF 60 and ALF 80.

3. Ensure the flow direction is correct. (Refer to section “Operating instructions”).

4. Flushing valve on ALF 20 and larger models are a wafer type butterfly valve. The

pipe work must allow the valve free entry into the pipe, when it turns.

5. Filter shall not be installed with the flow diverter shaft or actuator downwards.

6. Do not mount butterfly valves directly on the filter inlet or main outlet flanges.

There is a risk that the valve disc contacts the flange internals and could not be

opened or closed properly.

7. Non-return valves causes turbulent flows and is not recommended in front of the

filter. Ensure minimum 6 times pipe diameter from the non-return valve to the filter

inlet.

8. Flushing pipe can be connected to pipe system after a heat exchanger in order to

obtain back pressure for the flushing outlet. (See Installation example)

9. Flushing valve shall be tightened until the valve does not leak.

NOTE

Make sure the flushing valve is centred and not excessively tightened. There is

risk that the valve body can break during operation.

10. To avoid water hammer and excessive flow during back flushing initiation,

flushing pipe should be installed so that the pipe can be water filled at all times.

11. Make sure differential pressure (DP) between filter’s inlet & flushing outlet must

not exceed below values.

i. For (ALF 40, 50, 60 & 80) = 2.5 barg.

ii. For (ALF 10, 15, 20, & 30) =3.0 barg.

NOTE

DP pressure beyond above mentioned values could create serious damage on

the filter basket & other internal parts.
