Precautions for the FRZ series
●
Selection
Look at the "Handling Instr uctions and Precautions",
"Specifications", "Various Characteristics", "Dimensions", and
other technical materials for each product to make the correct
decision.
●
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.
●
Direction of flow
1. Connect the filter regulators and regulators so that the medi-
um 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 direc-
tion of flow of the medium being used (filter regulators, regula-
tors on page
❽
and residual pressure exhaust valves on page
⓬
.

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.
2. Do not attach piping so that just one side is fixed as shown in
the following diagram. Support external piping separately.
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 possible 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.

Mounting (installation) and piping
NOTE
Applying bending moment or twisting moment may damage
the product.
NOTE
It there is not enough allowance for maintenance space, it
will be impossible to remove the filter regulator bowl
assembly and replace the filter.
NOTE
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.
NOTE
Connecting the products so the medium flows in reverse will
cause the product to stop functioning and damage it.
NOTE
If the product is not securely fixed in place, it may fall over,
be dropped, or operate abnormally and may cause an injury.
