MAINTENANCE GUIDE FOR THE JVS-10SLGFS, JVS-15SLGFS & JVS-20SLGFS
* Cleaning, inspecting and/or replacing parts can be done by following the procedure below.*
Read the entire procedure before taking apart the meter. Be careful when handling parts!
1) Remove the 4 corner hex bolts (1) and remove the
flow meter from the manifold.
2) Remove the remaining 4 hex bolts (2) with a 5mm
hex key.
a. Reinsert 2 of the bolts you just removed, the 2 on
opposite ends work best, so that they are only
holding by a few threads. While holding the
upper housing firmly, tap the 2 bolts to separate
the upper and lower housings (3 & 4). Do not pry
or twist the housings to separate them, as this may
damage internal parts of the meter.
3) Once the housings are separated:
a. Remove the gears (4) and shafts (6). Lift the
gears straight up off of the shafts to avoid
damaging the shafts.
b. Remove the o-ring (7).
c. Clean the gears, shafts, meter bodies, o-ring
groove and shaft holes using solvent and a small
brush.
d. Inspect the gears and shafts. The gears should
spin freely on the shafts.
4) To reassemble the meter:
a. Replace the old o-ring if it is PTFE and replace it
with a new one.
b. Reinsert the shafts into the shaft holes and reinsert
the gears as well. Make sure the gears are
spinning freely.
c. Keep the meter housings as parallel as possible
during reassembly. Line up the index marks
which are located on either end of the upper and
lower housings.
d. Replace the 4 hex bolts (2) that were removed last
and tighten them to approximately 15Nm (this is
hand tight). Do not force the housings together as
you could damage the meter. Tighten the bolts a
few turns at a time, switching to another to gently
secure the housing together. Over tightening will
not damage the meter but the bolts can break if
tightened too much.
5) After reassembly make sure the gears spin freely
by gently blowing air into the inlet. You should
be able to hear the gears spin given a moderate
background noise level.
6) Reinsert the 4 corner hex bolts (1) and tighten to
approximately 15Nm (this is hand tight).
