3 Function, set-up and commissioning
3.1 Description of function
• The ACS 921 is a cleaning device that is primarily intended for use with watch parts.
• The ACS 921 has six process positions which are distributed every 60° on a turntable.
• Five cleaning baths, one with ultrasound function and one drying position.
• The watch parts are fitted into the matching plastic or metal baskets.
(for details of original accessories, see Section 9.2).
• The baskets can then be inserted into the basket holder provided for this purpose.
• After this, the basket holder is snapped into the operating position by means of a bayonet lock.
• Next, select the desired programme on the display and press the start button.
• The handling of the cleaning baths and their fluids and the creation of programmes are described in
more detail in Section 4 Operation.
3.2 Setting up
• Remove the ACS 921 and the accessories supplied from their packaging and position them at the desig-
nated set-up location.
Due to the weight of the device, this must be done by two people!
• Keep the packaging for any returns in case repairs are required.
• The outlet opening of the venting fan (top) must not be covered.
• If the installation room cannot be sufficiently ventilated or cannot be ventilated at all, we recommend
using an activated carbon filter, which can be ordered as an accessory. It is also possible to connect an
exhaust air hose with a connecting piece (accessory). (see Section 2.6)
In any case, room ventilation is very important and it is the responsibility of the operator of
the ACS 921 to ensure people are protected!
• The inlet opening of the heater fan (rear) must not be covered.
• Remove the packaging material from the ACS 921.
• Check the ACS 921 and accessories for completeness. (other accessories can be ordered through Cus-
tomer Service)
• Connect the ACS 921 to the mains using the connection cable supplied.
Please note the power input specifications!
