1. Installation
It is necessary during installation to
observe codes of good practice, to comply
with local requirements and to follow the
installation instructions. The installation
location should be protected against frost
and be easily accessible.
1.1 Assembly (Fig. 1)
1. Thoroughly flush pipework.
2. Close valves 1 and 2 .
3. Install the Y strainer 3
●
Where possible, fit in horizontal
pipework.
●
Seal plug 6 pointing downwards
4. Slowly open valves 1 and 2 .
2. Cleaning
Regular cleaning of the strainer is
recommended.
2.1 Drinking water systems
In drinking water systems it is recommended
that the strainer be cleaned at interval of
more than six months.
2.2 Other installations
The time interval between cleaning depends
on the degree of contamination in the
system. Where exessive dirt is present, the
blanking plug 6 can be replaced by a valve
to enable bulk deposits to be cleaned out.
●
If this is not done, strainer blockage
can occur, resulting in pressure loss
and reducing water flow rate
●
The strainers are of stainless steel.
Red deposits from the pipework do
not affect the function or filtering
efficiency.
3. Maintenance
1. Close valves 1 and 2 .
2. Open seal plug 4 .
