Default Time Intervals

At the factory there are five time intervals that have been preset for this device.

See Fig. D

180 seconds (3 minutes):
Standard time for a normal level of dirt. The time interval setting appears automatically on the display when the device is plugged in.

300 seconds (5 minutes):
Recommended for the first cleaning of objects that have not been cleaned for a long time.

480 seconds (8 minutes):
Recommended for the first cleaning when several objects are cleaned together.

090 seconds:
This is the shortest time interval. Recommended for very light levels of dirt or if a short period of recleaning is required. Once the water is noticeably dirty, it must be changed. If you wish to remove any residual dirt from the cleaned surface, clean the object again for 90 seconds in fresh liquid.

600 seconds:
This is the longest time interval. Recommended to increase the effectiveness of the cleaning.

Note: If the selected cleaning period is too long, it can lead to insecurely attached items, such as fittings, stick-on labels or decorations becoming detached from the object being cleaned. The same applies to other insecure items, e.g. the screws on spectacles, which may be come lose during the cleaning process.

Before Initial Use

Unpacking and setting up the ultrasonic cleaning device:

• Take the device carefully out of the box, remove the transport packaging and check the device for any possible damage that may have occurred during transport. Check also that all of the parts are present:
  1 x basket insert
  1 x curved insert
  1 x CD holder
• If not all of the parts are present or your new device is damaged, please contact the service hotline (see guarantee notice).
• Place the ultrasonic cleaning device in such a way on a firm, flat surface that it cannot tip over. This surface should be easy to clean, brightly lit and readily accessible. Do not place the device on surfaces that may become hot, e.g. on hotplates or next to a gas cooker.
• Insert the mains plug into a power socket. The number (180 seconds) appears in the display as standard.

Ensure that the mains voltage is 220 -240 V! (See the type plate on the underside of the device). The device might otherwise be damaged.

Operation

Fittings, stickers and decorations that are loosely attached to objects, as well as other loose parts, e.g. screws on / in spectacles, may become detached during the cleaning process. You should therefore clean such items not more than once a month.

Note: The On-switch "ON" and the Off-switch "OFF" simply control the time interval of the timer or the cleaning process. The actual switching on and off of the device is controlled by the mains plug .

Cleaning without the Insert

• Ensure that the device is disconnected from the mains supply.
• Open the lid manually.
• Place the object to be cleaned into the stainless steel tank .
• Then fill the stainless steel tank with normal tap water.
• The liquid must cover the object that is to be cleaned, but must not exceed the mark indicating the maximum filling height.
• If the stainless steel tank overflows, wipe off the outside of the device immediately until dry.

Never use the ultrasonic cleaning device without water as the device may be damaged!

Operation

1. Close the cover and insert the mains plug .
   The figure (180 seconds) appears in the display as standard – this is the standard time for a normal degree of soiling.
2. Select the desired time from five possible intervals: (180 → 300 → 480→ 090 →600). Use the timer button to set the desired time according to the degree of soiling.
3. Press the On-switch and start the cleaning process. The blue indicator light on the lid illuminates while the time in the display counts down to 0.
   Note: During the cleaning process a quiet vibration noise can be heard; this is caused by the cleaning process.
4. After the set time has elapsed the cleaning process is automatically stopped, the blue indicator lamp goes off and the display shows 000. The originally selected time interval in minutes/symbol remains visible.
5. Press the Off-switch to stop the cleaning process prematurely if necessary. The time remaining from the selected time interval is shown on the display. Press the On-switch again to resume the cleaning process. Or select a new time interval using the timer button and press the On-switch again.
   
   You can repeat the cleaning process in order to intensify the cleaning effect.
   If the cleaning process is started several the liquid becomes very warm (approx. 41°C after the first cleaning process and approx. 60°C after the third in spite of a five-minute cooling down phase). However, it is recommended that between the cleaning processes a pause of at least five minutes is inserted in order to allow the device to cool down. Do not change the time interval while a cleaning process is still running. Allow the time interval to expire normally, thus ensuring that the cleaning process is properly time-controlled.
6. If you wish to repeat the cleaning process, press the timer button . The next timing program appears on the display .
7. Set the desired time interval from the five time interval settings available using the timer button .
8. Press the On-switch and start the cleaning process.
9. After the cleaning process has ended, remove the mains plug from the socket, open the cover and take the cleaned object out of the device.
   Note: In order to avoid lime residues, always empty the stainless steel tank and wipe dry with a fabric or microfibre cloth. We recommend that the liquid should be renewed after every cleaning process if possible.
10. Please store the device in a cool and dry place.

Cleaning with Inserts

Note: The basket insert absorbs one third of the ultrasonic waves and therefore reduces the cleaning performance. It may therefore be necessary to carry out several cleaning processes.

Basket Insert :

• If you would like to clean sensitive and small objects, please use the basket insert (see Illustration A).
  
  Place the item to be cleaned in the basket insert . You can clean several items together in one cleaning procedure. However you should ensure that the items do not touch one another in order to avoid damage (e.g. scratches).
• Place the filled basket insert carefully in the device.
• Fill the device with water. The liquid must cover the item that is to be cleaned, but must not exceed the mark indicating the maximum filling height.
• Then start the cleaning process as described in paragraphs 1 to 10 of the section "Cleaning without an Insert".

Curved Insert for Watches :

Cleaning straps of waterproof watches:

• Please use the curved insert supplied for watchstraps made of metal.
• This curved insert is tall enough to project above the MAX. marking to allow watch straps to be placed in the cleaner.
• Attach the watch so that the watch mechanism housing sits above the surface of the liquid (see Illustration B).
  
  This means that the watch mechanism housing does not have to be detached from the strap.
  
  If the watch mechanism is in the liquid, it may be damaged during the cleaning process by the ultrasonic waves.
• Carefully place the curved insert with the wristwatch in the device.
• Fill the device with water. The liquid must cover the object that is to be cleaned, but must not exceed the mark indicating the maximum filling height, or the watch housing must be outside the liquid.
• Then start the cleaning process as described in paragraphs 1 to 10 of the section "Cleaning without an Insert".

CD holder for CD/DVDs :
Cleaning CDs and DVDs (see Illustration C):

• Insert a CD or DVD into the supplied CD holder .
• Fill the device with water.
• 2 CDs or DVDs can be cleaned at the same time by using the ring as a spacer.

Using a Cleaning Concentrate

• It is possible to use a cleaning additive for problematic or stubborn dirt such as grease, resin, rust, wax, pigments, etc., which cannot be removed with water (see the section on "Cleaning Methods").
• It is essential to read the warnings and manufacturer's information before using the product.
• Please ask in specialist shops, such as those dealing in watches or jewellery, for advice.

Cleaning Methods

General Cleaning:

• Use normal tap water for general cleaning (the water should completely cover the item to be cleaned, although the maximum filling height should not be exceeded).

Basic Cleaning:

• Cleaning concentrates can be used to intensify the cleaning effect of the device (e.g. commercially available washing-up liquid).
• Fill the stainless steel tank with a cleaning mixture consisting of five parts of water and one part of washing-up liquid (e.g. 250 ml of water, 50 ml of washing-up liquid).
• Please note the information provided by the manufacturer on the pack.

Partial Cleaning:

For the partial cleaning of large objects please use the device with the cover open. During operation avoid contact with the liquid! Ultrasound is harmful to the skin and bones.
