CAUTION
Rotation check should be performed at low
rotor r.p.m.
Violent rotor spinning may cause a damage
to the components, such as bearing
seizure.

Front Cover Installation
Firstly install the O-ring (108) on the front cover.
If the O-ring is damaged or swollen with metered
liquid, it will not fit in the groove. If such is the
case, replace with a new one.
Align the locating pin of front cover with its pin slot
in the meter body and, fitting the rotor shafts into
rotor shaft sockets on the front cover, force the
meter body until the locating pin fits firmly in the
pin slot in the meter body without slanting the front
cover. Install six hex bolts (M6) and tighten them
evenly until the front cover is closely in contact
with the meter body.
④
Confirming Freely Rotation
With air or water, make sure to see that the
rotors move freely and that the register counts in
response.
CAUTION: This meter is incompatible with other types of register. Never attempt to
replace.
