Safety instructions are intended to protect users from dangerous situations and/or
prevent material damage. In the operating instructions, the severity of the potential risk can
be indicated by the following signal words:
install
Switches should only be installed in systems that do not exceed the maximum
pressure Pmax (see type label).Install switches only when power is off
(electrical, hydraulic/pneumatic).
!
danger
Vibration and violent vibration must be avoided during transportation.
Even if the switch housing is not damaged,
Internal components can also break down and cause failure.

Piping method:
When piping a product, use a wrench to pipe the metal parts (pipe fittings) that
are integrated with the piping part.
If you use a wrench in other parts, the flow switch may be damaged.
In particular, no spanner can be used on the M12 connector.
Otherwise, the connector may be damaged
If the switch is tightened outside the torque range, it may be damaged. If assembled
without a specified tightening torque, it may loosen the joint thread.
Installation of piping:
Please do not let the sealing
tape into the tube.
Piping connection:
Please do not relax and cause
liquid leakage.
Please strictly observe the safe torque value of piping:
Attentional collision
Fixed wrench
Fastening wrench (please refer to torque value)

Debugging/operation
The pressure switch can only be debugged and operated by authorized personnel.
Note that the casing surface may become very hot if the operating temperature is high!
!
warning
Do not put the switch into operation when the switch itself or the connecting cable is damaged.
Do not use any sharp, hard objects to make entries.
The key may be damaged by something sharp and hard.

Only remove the switch in case of power failure (electrical, hydraulic/pneumatic).
Switch disconnection from pressure and power supply must be performed by trained
or directed personnel in accordance with the most advanced standards.
!
danger
Maintenance/cleaning
Disassemble
The pressure switch does not require maintenance.
Periodically check whether the switch is working properly.
If the switch does not work properly, stop the operation immediately.
!
warning
Be aware that the surface of the shell may become very hot if the operating
temperature is higher!
!
warning
Use of improper cleaning agent may damage the switch.
The following cleaning agents can be used to clean polycarbonate: mild soap or detergent
Isopropyl alcohol
Immediately after cleaning, rinse with water. Do not leave cleaner on the surface of the
product. Do not clean products in high heat or direct sunlight.The following cleaning
agents are known to affect the integrity of polycarbonate components and should not
be used: ZEP Fast 505, Pinesol, Formula 409
Halogenated solvents (benzene, gasoline, acetone or carbon tetrachloride)
Strong alkalinity
Methyl ethyl ketone
