2 Fundamental Safety Instructions
2.1 Intended Use
The product is built in accordance with the latest standards of technology and is delivered in a safe operating con-
dition; however, hazards may arise during use.
The round vacuum suction plate SUF is designed to handle flat, smooth workpieces, such as sheet metal, plastics,
coated wood, granite, or concrete. To generate holding force, the vacuum suction plate is connected to a vacuum
supply at the customer’s premises.
It is especially suitable for the following applications:
• General use for handling processes in vacuum automation and with manual vacuum lifting devices
• Processes requiring high suction forces or acceleration
• Use in dirty environmental conditions, e.g. oil
• Handling of thin-walled workpieces, e.g. thin metal sheets
The product is intended for industrial and commercial applications.
To conserve compressed air, an optional touch valve is available as an accessory which activates the vacuum just
prior to placing the suction plate on the workpiece.
2.2 Non-Intended Use
Schmalz does not accept any liability for any direct or indirect losses or damages that result from using the product.
This applies, in particular, to any use of the product that is not in accordance with the intended purpose and to any
use that is not described or mentioned in this documentation.

4 Near Field Communication (NFC)
NFC (Near Field Communication) refers to a standard for wireless data transfer between different devices over
short distances.
An NFC chip is integrated in the suction cup connection disc, which functions as a passive NFC tag that can be read
or written by a read or write device with NFC enabled such as a smartphone or tablet.
Read access only can be obtained via a website viewed in a browser. This does not require an additional app. It re-
quires only that NFC and the internet connection are enabled. However, we suggest using the Schmalz Control-
Room app as it allows additional information to be made available. The app is available in the Google Play Store.
For the best data connection, place the reading device
on the NFC symbol in the middle.
The reading distance is very short for NFC applications. If necessary, find the position of the NFC an-
tenna in the reading device used.

6.2 Storage of Suction Cups and Other Elastomer Products
NOTE
The effects of ozone, light (especially UV), heat, oxygen, humidity as well as mechanical in-
fluences can reduce the service life of rubber products.
Damage to the suction plates due to incorrect storage!
4You must store rubber parts such as suction cups and suction plates in a cool place (0°C to
+15°C, max. 25°C) that is dark, dry, low in dust and that offers protection from the weather,
ozone and drafts. They should also be free of tension (e.g. stacked appropriately to avoid defor-
mation).
6.3 Storage Regulations
Observe the following storage regulations in accordance with DIN7716 and ISO2230:
• Suction cups must be protected against light and air during storage. Airtight, sealed containers can be used
for this purpose. Alternatively, they may be stored in airtight plastic bags in small load carriers or boxes with
covers (e.g. a dark intermediate layer).
• The workpiece temperature must be between 0° C and 25° C.
• Suction cups must be packaged and stored free of voltage. This applies to shipping packaging as well.
• Solvents, fuels, lubricants, chemicals, acids, disinfectants, and other volatile substances stored in containers
that are not gas-tight may not be stored in the same storage room as suction cups.

7.5 Installing the Touch Valve (optional)
1. Remove the plug in the G2 thread.
2. For sealing, prepare the male thread in the area
displayed on the touch valve with a PTFE strip or
low-strength thread lock before mounting.
3. Screw the touch valve into the G2 thread until it
stops (SW11 hexagonal mid section).
ðThe touch valve must be screwed in so that the button protrudes at least 1 mm over edge of the sealing ring.
This ensures that the button is actuated just before the sealing edge is placed on the workpiece.
8 Maintenance and Cleaning
8.1 Cleaning the Suction Plate
1. For cleaning, do not use aggressive cleaning agents such as industrial alcohol, white spirit or thinners. Only
use cleaning agents with pH 7–12.
