Strainer System 5 – “Smart Secondary Strainer”
`
Description of Smart Secondary Strainer:
The base of strainer basket SB85M houses a strong samarium-cobalt magnet. When the basket is in place it
draws up the strainer plate (which is made from ferritic stainless steel) thereby rendering it inoperative – it is
as if there is no secondary strainer. Any solids small enough to pass through the basket cannot therefore
accumulate within the unit. When the basket is removed the strainer plate drops into place, providing a very
solid, tamper-resistant secondary strainer. The plate contains very small perforations (1.5mm
Ø
), thereby
preventing virtually any solids from entering the waterway. But the holes are sufficiently numerous to prevent
the system from completely blocking. The strainer plate cannot be bypassed by hand.
Special Maintenance Instructions
If the strainer plate gets sticky then there is a slight chance that it will not open when the basket is reinserted
after cleaning. This risk can be eliminated if the basket is flushed every day with 1 litre of hot soapy water.
This will ensure that sticky residues, grease etc cannot accumulate on the mechanism.
