①
Do not loosen the V band while pressure is applied to
the product
Caution
①

When supplying pressure when starting the pump,
release air by opening the air release valve at the
top of
the pump. (Fig. 1-3)
Fig. 1-3 Air release
②
During operation
When pressure is applied during the starting of the
pump, make sure that each connecting part is
completely sealed. Stop operation if any abnormality
such as fluid leakage is confirmed.
Do not restart operation until the cause has been
investigated and corrective action (replacement with a
new O ring, retightening of the fitting) has been taken.
Warning
①
Incorrect maintenance procedure can result in fluid
leakage or falling of the cover leading to unexpected
accidents.
Maintenance
should
be
performed
according to the procedure indicated in the Operation
Manual.
②
Make sure that the line is stopped and the pressure is
atmospheric pressure (gauge pressure: zero) before
starting maintenance and inspection.
Caution
①
Element replacement timing
Replace the element with a new one when the
replacement timing has come.
Element replacement timing
When pressure drop reaches 0.1 MPa.
②
Element replacement
Maintenance should be performed according to the
procedure in this operation manual. Improper
handling can cause damage and malfunction of
equipment and machinery.
Make sure that the pressure is atmospheric pressure
(gauge pressure: zero) before the replacement of
the element.
Mount the cover connecting parts (V band etc.) to the
specified positions after replacement of the
element.
③
Cleaning of parts
For proper sealing during the replacement of the
element, clean off any paint etc which is stuck to the
threads of the sealing seat surface and the cover
connecting part.
④
Replacement of the sealing
Replace any deteriorated or swollen
“O” ring or sealing
of the holder assembly.
Replace the sealing after a year of usage or when fluid
leakage is generated.
⑤
Cover connecting parts
Do not use any cover connecting parts (V band) which
is deformed or scratched.
⑥
Temperature
The usage of this product at high temperature (40 to
80
o
C) may cause burns.
To prevent burns, replace the sealing after confirming
that the temperature of the filter surface and operating
part (V band, element) is lower than 40
o
C
