Prevent pipe strain or stress from occurring when making meter or
accessory repairs. Pipe strain and stress occurs when the pipes
are not supported or are not aligned correctly to the meter. The
weight of the pipes must always be supported independent of the
meter. This means that the meter and accessories can be easily
removed without affecting the pipes or the pipe alignment. Never
leave any of the pipes hanging.

If the meter is used for seasonal work, the meter should
be removed from the system and thoroughly ushed with a
compatible liquid at the end of each season. To ush the meter,
remove the drain plug on the front and rear covers. Then ush the
product from the front and rear covers. If ushing with water, extra
care should be taken to drain the meter completely and dry all
internal parts. Rell the meter Immediately with a compatible liquid
(or oil misting). Relling is essential to preventing corrosion and
ice damage that can result from any moisture that was overlooked
after ushing and drying.

Removing ange gaskets When removing the ange assembly,
always carefully scrape off the ange gaskets. Make sure that the
ange surface has been scraped clean. Discard the old ange
gasket and install a new ange gasket. Never reuse old ange
gaskets.

Examine all fasteners to make sure they are not bent, rusted, or
have pulled threads. The threads should all appear evenly placed.
If the bolts are bent, check the housing and cover for atness. Use
a straight edge to determine atness.

Look for gaps when disassembling a meter. Use a feeler gauge
to check for gaps between the bearing plate and housing. If you
do nd gaps, check the bearing plates for atness with a straight
edge. Gaps can be caused by shock problems. If shock problems
exist, they must be resolved. Contact your full-service distributor
for assistance if this occurs.

Check the O-rings for damage. Cracked, rough, or worn O-rings

be veried and resolved. Contact your full-service distributor for
assistance if this occurs.
