downstream of the switch piping.
When abruptly reducing the size of piping or when there is a
restriction such as a valve on the upstream side, the
pressure distribution in the piping changes and makes

restriction measures such as these should be implemented
on the downstream side of the switch.
[For water]
used as a scaffold during piping.
Damage may occur if an excessive load is applied to the
switch. Especially when the switch supports the piping, do
not apply a load of 15 N·m or more to the metal part of the
switch.

When used with the downstream side open, be careful of

Warning
wiring.
Incorrect wiring can cause the switch to be damaged and
malfunction. Verify the color and the terminal number in the
instruction manual when wiring.
lead wire.
Repeatedly applying bending stress or stretching force to
the lead wire will cause it to break.
Make sure that there is no faulty wiring insulation (contact
with other circuits, ground fault, improper insulation between
terminals, etc.). Damage may occur due to excess current
flow into a switch.
or high voltage lines.
Wire separately from power lines and high voltage lines,
avoiding wiring in the same conduit with these lines. Control
circuits including switches may malfunction due to noise
from these other lines.
Although switches indicate excess current error if loads are
short circuited, all incorrect wiring connections cannot be
protected. Take precautions to avoid incorrect wiring.

generated.
When there are units that generate a large amount of surge in
the area around pressure switches, (e.g., solenoid type lifters,
high frequency induction furnaces, motors, etc.) this may
cause deterioration or damage to the switches' internal
circuitry. Avoid sources of surge generation and crossed lines.
protection against lightning.
Flow switches are CE compliant; however, they are not
equipped with surge protection against lightning. Lightning
surge protection measures should be applied directly to
system components as necessary.
the likelihood of splashing or spraying of
liquids exists.
Switches are dustproof and splashproof; however, avoid using
in an environment where the likelihood of heavy splashing or
spraying of liquids exists. Since the display unit of the remote
type switches featured here is not dust or splash proof, the
use in an environment where liquid splashing or spraying
exists must be avoided.
[For air]
ambient temperature range.
Fluid and ambient temperatures are 0° to 50°C. Take
measures to prevent freezing fluid when below 5°C, since this
may cause damage to the switch and lead to a malfunction.
The installation of an air dryer is recommended for eliminating
condensate and moisture. Never use the switch in an
environment where there are drastic temperature changes
even when these temperatures are operated within the
specified temperature range.
[For water]
ambient temperature range.
The fluid and ambient temperatures range for the switches is
0° to 50°C (and 0° to 90°C for high temperature fluid). Take
measures to prevent freezing fluid when below 5°C, since this
may cause damage to the switch and lead to a malfunction.
Never use the switch in an environment where there are
drastic temperature changes even when these temperatures
fall within the specified temperature range.
