Cleaning Unit
The manufacturer recommends using the High Output Airblast Cleaning System for the
compressed air supply; this is a compressor in a weather-proof plastic housing. This
complete system is operated through a relay in the sc100/sc1000 controller.
DANGER
Only qualified personnel should conduct the tasks described in this instruction
sheet.
CAUTION
Make sure the cleaning unit is disconnected from the compressed air during
installation and service work.
When using an external compressor or an existing compressed air system, a suitable
valve is required (and, if necessary, a pressure reducer) and can be configured through a
relay on the sc100/sc1000 controller.
Unpacking the instrument
Verify that all items (refer to Figure 3 on page 3 ) are included. If any items are missing or
damaged, contact the manufacturer or a sales representative.
Do not send the items without contacting the manufacturer or a sales representative.
Note: Retain the original packaging materials. Instruments returned for service should be shipped in
the original packaging material to protect against damage during transportation.
