FIREli nk - 25 is a ver y l ow m aintenance detection system . If r equired, ext er nal cleaning of the unit should

be performed using a damp (not wet) c loth. Do not use solvent s as these may mar the front panel l abel.

wil l need r eplacing. To r eplac e the fil ter, simply r em ove the front cover and pull the filter out from t he

m ai n unit. Slide the repl ac em ent fil ter in so that the ‘Direction of flow’ arrow printed on the car ton

Used separators are not

intended for re-use and should be disposed of.
