Maintenance
4 Visually check the filter for contamination.
5 Install a new sinter filter with o-ring at the bottom of the filter tip.
6 Reinstall the sniffer tip.
7 Switch on the Protec P3000.
8 Hold finger against the capillary filter:
You should be able to feel the resulting vacuum.
9 If the warning “Flow through capillary too low” remains after releasing the finger
from the capillary filter, replace the sniffer tip first. If this does not cure the
problem, the capillary in the sniffer line is clogged and the complete sniffer line
needs to be replaced.
10 Please recalibrate the Protec P3000 for most accurate display of leak rate.
7.5 Replacing the filter pad of the sniffer tip
(for SL3000XL only)
When you want to change the filter pad, which is placed between sniffer tip and the
handle, you have to take off the sniffer tip first:
1 Loosen the cap nut by turning it to the left.
Notice
If the screw is too tight you may use a screw wrench (SW21):
or: Place a screw wrench at the recess of the cap nut and loosen the nut carefully
by turning the wrench to the left.
Notice
Don’t use the blue paper pads between each filter pad.
2 Remove filter pad.
