Mounting (installation) direction, support, and securing
1.
The products cannot be mounted (installed) if a bending moment or twist-
ing moment is applied to the product or piping.
2.
Do not attach piping so that just one side is fixed as shown in the follow-
ing diagram. Support external piping separately.
Design and selection
Mounting (installation) and piping
Applying bending moment or twisting moment may damage
the product.
The muffler must be prepared by the user.
(In case of NPT thread specifications)
Operating the knob and the moment caused by the OUT (second-
ary) side pipes may damage the product's piping connections.

Maintenance space requirements
Assure there is sufficient space for maintenance inspections and mainte-
nance work.
See the dimension diagrams for each of the products regarding the mainte-
nance space.
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.
If there is not enough allowance for maintenance space, it will be
impossible to do maintenance inspections and maintenance work so the
equipment may stop or the product may be damaged.
3. Use the D
□
module or a bracket to install all the products.
4. The product can be mounted (installed) in any direction. It is also possi-
ble to install it with the bowl of the filter on top.

5. When mounting (installing) the product, always make sure it is secured
and sufficiently supported.
If the product is not securely fixed in place, it may fall over, be dropped,
or operate abnormally and may cause an injury.
●Direction of flow
1. Connect the filter regulators and regulators so that the medium flows in
the IN port (primary) side and out the OUT port (secondary) side.
2. Connect the residual pressure exhaust valves so that the medium flows
from the 1 (P) port (primary) side to the 2 (A) port (secondary) side.
3. Use the flow marks on the products to identify the direction of flow of the
medium in the filter regulators, regulators, and residual pressure exhaust
valves.
See the "Handling Instructions and Precautions" for each product
regarding the relationship of the flow marks and direction of flow of the
medium being used .
Connecting the products so the medium flows in reverse will cause the
product to stop functioning and damage it.
●Attaching steel pipes and fittings
If steel pipes and fittings are attached to the threaded sections of the alumi-
num die-cast parts of the product, tighten them to the torque recommended
in our standards.
Tightening with excessive torque may damage the product or injure
workers or operators.
