NOTE
The above replacement intervals are recommendation only. The intervals may change depending on the
operating conditions. These intervals do not mean the warranty periods either. The result of the regular
maintenance may determine when to replace the parts.
Replacement of Pump Unit
The pump unit can be replaced in a single step as shown in the
figure. When attaching the pump unit to the main unit, position
the grooves of the pump unit at the rails of the main unit and push
the pump unit.
Do not push the center diaphragm. Push the part labeled "PULL".
And as the connecting point (flow path) of the pump unit is
greased, be sure to check for any dust.
Replacement of Flow Sensor
After the flow sensor is replaced, the operation must be checked
by a qualified service engineer.
For the stable operation of the detector and safety, ask a
qualified service engineer to take care of replacement of the
parts whose operation must be checked. Please contact our
sales department.
