the element.)
Check the port size for piping the valve and fitting which are appropriate for the operating conditions.
Flush piping with air before operation, confirming there is no abnormality such as fluid leakage.
Connect piping so that air can be discharged from the case.
Piping in which a small amount of air constantly returns to the tank by a resin tube
from the air release valve is helpful to release air properly. (Fig. 5-4)
If the location of the pump is high, the pump may idle when it is restarted.
Care should be taken.
Fix the piping of the inlet and the outlet to the base using a saddle so
that it is not subjected to vibration or weight.
6. Maintenance
1-1) Replacement of the element
Replace the element with a new one when the replacement timing has come.
* Continuing to use an element which is overdue for replacement may cause breakage of the element and the
equipment.
[Replacement timing of the element] When differential pressure (pressure drop) reaches 0.1MPa.

1-2) Element Replacement Procedure
1
[Removal of operation panel]
①
Stop operation
②
Close the valves in order of inlet (IN) and outlet (OUT).
③
Open the air exhaust valve to make the internal pressure atmospheric pressure.
(Figure
③
)
④
Discharge fluid inside by opening the fluid discharge valve.
⑤
Loosen the tightening bolt of the V band to remove the stopper.
(Figure
⑤
on the right)
Tightening bolt can be loosened by a hexagon wrench [flat size 6mm].
⑥
Remove V band / cover.
Rotate the cover counterclockwise and lift upwards to remove it. (Steps (1) and (2)
in Figure
⑥
)
⑦
Check O-ring. If there is any failure such as swelling, replace O ring with a new
one.

Warning: Remove the V band and the cover after confirming that the
pressure in the filter is atmospheric pressure (gauge pressure:
zero).
