Has everything been supplied?
Check the scope of supply:
Completely assembled pressure switches; with flush version PS-20 including pre-assembled
■
sealings and protection cap.
Inspect the pressure switch for possible damage during transportation. Should there be any
■
obvious damage, inform the transport company and WIKA without delay.
Keep the packaging, as it offers optimal protection during transportation (e.g. changing installation
■
location, shipment for repair).
Ensure that the pressure connection thread and the connection contacts will not be damaged.
■
In order to protect the diaphragm, the pressure connection of the instrument PS-21 is provided with a special
protection cap.
Remove this protection cap only just before installing the pressure switch in order to prevent any
■
damage to the diaphragm or the thread.
Keep the protection cap of the pressure connection thread and the diaphragm for later storage or
■
transport.
Mount the protection cap when removing and transporting the instrument.

Diaphragm test for your safety

relevant component.

Check the diaphragm visually for any damage (PS-21).

Use the pressure switch only if the diaphragm is undamaged.
