Diesel engine
– Then, check the cartridge for damage to the paper bellows and the rubber seals. In
case of damage (cracks, buckling, impressions, etc.), use a new cartridge. Rips or
holes in the paper bellows can easily be found when shining through with a hand
lamp (see illustration). To make even small damage visible do not perform this
examination in direct sunlight or bright daylight, but if possible in a darkened room.
Carefully inspect each crease individually using a suitable flashlight. Damaged filter
cartridges may never be reused in any case. Use only original filter cartridges (ROPA
main element item no. 301022500; ROPA safety cartridge item no. 301022600). In no
case install filter elements with metal outside sheathing.
– Slide the main element with the open side first into the housing. Place the cover on
it, observe the position of dust emission valve (see illustration). The dust emission
valve must face downward (deviation ± 15° of the „UP/TOP“ mark is admissible); if
necessary, take off the lower part of housing and reinstall it after rotating.
– Attach wire spring closures in the groove (4) of the flange at the housing and
tighten along the perimeter in succession.
