10.3 Inspection of a unit fitted with a Flow Housing

Searchpoint Optima Plus should be inspected periodically and cleaned if necessary. The required frequency
of inspection will depend on local site conditions and will need to be established through experience.

housing. Keep the O-ring seals which are below the retaining nuts.

of the O-ring.

below the retaining nuts, are clean and in good condition. Replace if in doubt.
