FGG Series/ Safety Instruction
Be sure to read before handling.
These safety instructions are intended to prevent a hazardous situation and/or damage to human and
equipment by using FGG series properly.
Caution：Operator error could result in injury or equipment damage.
Warning：Operator error could result in serious injury or loss of life.
Incorrect handling lead to cause fluid leakage or displacement
Of the cover which result in unexpected accident..
Compatibility of the equipment shall be judged by system
designers with knowledge and experience.
Cautions shall be followed to avoid element damage
and ensure the performance and maintainability.
Operating condition range Design and installation
Warning
①Operating pressure
・Do not use pressure exceeding specified range.
②Operating temperature
・Do not use where temperature exceeding specified
range.
③ Operating fluid
・Do not use this for gases.
・Do not use with corrosive fluid.
・Do not use fluid which swell or deteriorates packing,
“O” ring or element.
④ Operating environment
・Do not use in corrosive environment.
・Do not use where exposed to vibration or impact.
Caution on operation
Warning
① Do not loosen V band while pressure is applied.
②Install V band correctly to specified position. (See
page 7)
③Replace deteriorated or swollen “O” ring.
Replace “O” ring in one year after starting use,
or fluid leakage occurs.
(See page 4 Table 1 :“O” ring for replacement)
④When supplying pressure for starting the pump,
open the relief port to discharge air.
⑤ Do not use V band which is deformed or thread is
grounded.
(See page 4 table 1 : V band for replacement)
Warning
①Design the system which operating conditions
including operating pressure, operating temp.,
operating fluid, and operating environment shall
be appropriate safe operation.
② Pressure drop (ΔP)
・Set the flow so that the initial pressure drop is
0.02MPa or less.
③ Space to install
・Reserve maintenance space for installation and
piping.
④ Flusing
・Flush piping line with air before the first usage.
⑤ Prepare air discharge circuit upon necessity.
⑥ For high temp. type, protection against burning
shall be prepared.
⑦Prepare drain or the circuit to discharge fluid
upon necessity.
⑧ Use the filter with circuit in which changing load
of the pressure and the flow is small.

FGG Series/Safety Instruction
Be sure to read before handling.
These safety instructions are intended to prevent a hazardous situation and/or damage to human and
equipment by using FGG series properly.
Maintenance Piping and operation
Caution
① Foreign matters shall be discharged from drain
outlet.
② Replacement of the element
When it is the time for replacement of the element,
replace with a new element immediately.
・The life of element-
・When pressure drop reaches 0.1MPa, replace the
element referring the procedure in this manual.
Incorrect handling causes the damage of equipment
and device, and the operation failure.
（See Page 6,7 : Replacement of element）
③ Cleaning of equipment
When replacing the element, clean “O” ting, packing
seat surface, the joint part of V band, and thread for
sealing properly.
④Surface temp.
Confirm that the surface temp. is 40oC or lower when
replacing the element. For high temp. use, attention
should be taken to avoid burning.
Caution
① Ensure the direction of ＩＮ/OUT for piping.
②Arrange piping so that air discharging work is
available.
③Check each port size for selecting valves and
fitting suitable for operating conditions. Flush
piping line with air before operation to check any
problem including fluid leakage.
④Fix the feet to the ground firmly using foundation
bolt(M12).
⑤The piping of INLET and OUTLET shall be fixed
firmly to the mounting frame using the saddle so
that load including vibration or weight is not
applied to the piping.
⑥ When supplying pressure for starting the pump,
ensure opening/closing of piping and connecting
parts are completely sealed. If fluid leakage is
present, stop operation immediately. Investigate
the cause, and replace “O” ring to a new one.
Then, tighten the fitting and perform any
corrective action for fluid leakage before restarting
operation.
⑦ When supplying pressure for starting the pump,
open the relief port(hexagon plug) to discharge air.
Release the air(loosen the hex. plug) at the same
time supplying the fluid to substitute air in the
product by fluid. When air is discharged, close the
relief port(tighten the hex. plug) before starting
operation.

orientation mark of the case and the cover match.
［In order of (1) and (2) on drawing on the right］
5 【Mount and tighten V band】
①Mount V band to the collar of the cover and the case correctly. [Refer Fig. (a), (b)］
Warning The cover may be fallen off due to incorrect mounting. Mount the cover properly
②Hit the circumference of V band lightly with plastic hammer for secure mounting.
③Mount T bracket to the latch correctly. [See Fig. (c)]
④Tighten the clamping nut to specified nut(position from where clamping position check pin can be inserted), and
insert the clamping position check pin. [See Fig.(c)]
⑤When tightening nut can not be tightened to specified position(position where clamping position check pin can be
inserted), replace V band and O ring to new ones. (See table 1).
Caution Clean V band and the contact surface between the cover and the case before mounting.
Dirty contact surface lead to cause leakage.
Warning Replace with a new V band when deformation or worn out by screw is found on the band
