diagram14, then according to diagram 14, firstly take off 3 pieces of screws (M3×8) (53), 3
pieces of spring washers (52), then take off bottom sealing cap (49), bottom sealing cap (48),
burette (46) and piston (47) respectively, clean the burette with distilled water repeatedly, then
absorb water drops on the burette (46) with distilled paper.
Install burette according to diagram 14, firstly install the piston (47) into burette from the top with
push rod tool, then install the burette (46) and piston (47) into protection cover (44), the top of
burette (46) should be tightly closed to the top sealing ring (45) but please be careful not to break
the burette (46), then install the bottom sealing ring (48) and the bottom sealing cap (49) properly.
At last, tighten the burette with 3 pcs of M3×8 screws (53) , 3 pcs of spring washers(52). Please
note that when tighten with screws (53), you must tighten it evenly to prevent burette from
leaking probably that may influence titration accuracy. Pull the piston (47) to the lowest point
with push rod (see diagram 14)
Diag.15
c.Install the burette (4) on volume titration unit (3), please note: the piston pole on the burette
should be inserted into the groove of the push rod, then tighten the screws (50) on the burette
(4); insert dripping tube (9) according to diagram 15; then connect the feeding tube (2) (the
longest one), the feeding tube (6) (the shortest one), feeding tube (8) by tightening joint nut (4).
Note: Turn the joint nut (4) tightly to prevent from leaking.
