7 Maintenance
All Grant laboratory products are designed to comply with IEC1010-1 and can be flash tested.
Some are fitted with radio frequency interference suppressers. Therefore it is recommended that
only a d.c. test is performed.
Routine maintenance:
Check monthly that dust is removed from the grilles.
Check monthly that the line strainer which is fitted on the inlet pipe is clean, particularly when
foreign particles can enter the pumped liquid. Switch off, and shut off and drain any head of
liquid. Undo the strainer retaining nut on the underside of the brass fitting, remove the strainer
and clean it. Refit by reversing the procedure.
Inspect and replace where necessary any worn or damaged hoses.
