●
Selection
L o o k a t t h e H a n d l i n g I n s t r u c t i o n s a n d P r e c a u t i o n s,
Specifications, Various Characteristics, Dimensions, and other
technical materials for each product to make the correct deci-
sion.
●
Mounting (installation) direction, support, and securing
1.
The products cannot be mounted (installed) if a bending
moment or twisting moment is applied to the product or piping.
●
Preventing contamination by foreign matter
1.
Remove all foreign matter, such as metal chips, cutting oil, or
dirt, from inside pipes with compressed air blow (flushing) and
thorough washing before fitting the pipes.
2.
Do not allow foreign matter, such as metal chips, or sealing
tape from the piping threads, to get into the pipes when install-
ing the pipes and fittings.
●
Maintenance space requirements
Assure there is sufficient space for maintenance inspections and
maintenance work.
See the dimension diagrams for each of the products regarding
the maintenance space.
●
Attaching steel pipes and fittings
If steel pipes and fittings are attached to the threaded sections of
the aluminum die-cast parts of the product, tighten them to the
torque recommended in our standards.
2.
Do not attach piping so that just one side is fixed as shown in
the following diagram. Support external piping separately.
Design and selection
Mounting (installation) and piping
Note
Applying bending moment or twisting moment may
damage the product.
Note
The muffler must be prepared by the user.
Note
If a product is not securely fixed in place, it may fall over, be
dropped, or operate abnormally and cause an injury.
Note
Operating the knob and the moment caused by the
OUT (secondary) side pipes may damage the product's
piping connections.
Note
It there is not enough allowance for maintenance space, it
is impossible to remove the bowl assembly and replace the
filter.
Also, it is impossible to do maintenance inspections so the
equipment may stop or the product may be damaged.
Note
Tightening with excessive torque may damage the product
or injure workers or operators.
Note
Use a tightening torque of 2.21 to 3.69 ft
•
lbf if the various
pressure gauges are mounted on the NPT1/8 or NPT1/4
pressure port plate.
Note
Foreign matter entering the piping may damage the product
or reduce its performance and service life.
