O-Ring Installation
• The sealing of the fl ow cell is accomplished by four cut O-ring segments
and two round O-rings sealing the fl ow regulator. Refer to the illustration
below for special O-ring fi tting instructions. Butt all O-ring joints together
so there is no gap.
• Remove the O-rings during fl ow cell disassembly. Both the O-rings and all
sealing grooves should be examined for cleanliness.
• Wipe all surfaces carefully with a soft, lint-free cloth to ensure good sealing.
• The cross section of the O-rings should be round and smooth. If they are
fl attened, their ability to seal is reduced.
• Do not use liquid or paste sealant.
Do not scratch the sealing surfaces of the fl ow cell block.
Scratches to the sealing surfaces can cause irreparable leaks.
CAUTION! The 3-4630.390 (159 001 688) O-ring kit
comes complete with two O-rings (5 and 6) and a
single cord of material that must be cut and fi tted
into the O-ring groove of the fl ow cell (1 and 4).
