VLOXO CD-3840 Digital Ultrasonic Cleaner

FEATURES

INTRODUCTION

Use tap water. Chemical solutions are unnecessary in most cases.

Principles of ultrasonic cleaning
Millions of tiny air bubbles are generated inside the liquid by high frequency vibration. The air bubbles bust inside the liquid and shake off the debris to achieve the cleaning effect.

• Purified water or distilled water has the same cleaning effect as regular tap water for ultrasonic cleaning. Therefore using tap water is sufficient.
• When cleaning silver or coper items where oxidation has darkened the items, special solutions need to be added to the water to remove the oxidation.

Main Features

• Tank capacity : 700 ml / 0.74 qt; Tank size : 16.8x 10x 5.6 cm / 6.6″ x 3.9″ x 2.2″. Longest item that can fit is 16.8 cm / 6.6″
• Higher ultrasonic frequencies : 40-46KHz, faster cleaning speed
• A+B- ultrasonic transducer with German technology, 15% more powerful than regular transducers.
• Touch sensing controls for longer life and better water proof
• Blue LED indicator light inside the tank
• Digital control with cold blue LED display, 5 timer settings
• Industrial IC with better anti-interference ability

• Do not use solution containing abrasive substances or strong corrosive chemical solution not recommended by the manufacturer or the supplier
• Place the device on a dry and flat surface for operation.
• When the device is subjected to severe electromagnetic interference, it may malfunction, stop operating or lose control functions. If this happens, unplug the power cord then reinsert it to restart the device.

IMPORTANT SAFETY INSTRUCTIONS

When using electric appliances, basic precautions should always be followed, including the following

• Read all the instructions before using the appliance
• To reduce the risk of injury, close supervision is necessary when an appliance is used near children
• Only use attachments recommended or sold by the manufacturer.
• Do not use outdoors.
• To disconnect, turn all controls to the off (O) position, then remove plug from outlet. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord. Unplug from outlet when not in use and before servicing or cleaning.
• To reduce the risk of electrical shock, do not put the appliance in water or other liquid. Do not place or store appliance where it can fall or be pulled into a tub or sink.
• All servicing of this product, including transducer replacement, is to be conducted by qualified service personnel.
• Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or is dropped or damaged in any manner. Return appliance to the nearest authorized service facility for examination, repair, or electrical or mechanical adjustment.

ITEMS NOT SUITABLE FOR ULTRASONIC CLEANING

Soft Jewelry
Pearls, emerald, ivory, coral, agate, sea turtle shells, etc| These items are not hard, so scratches may occur during cleaning.
Welded, Plated and Glued Items: Welded or plated metal items, glued items| Ultrasonic cleaning may enlarge the gaps inside the welded joints, plated coating or glued items and may cause separation.
Watches
Except diver’s watches with depth rating over 50 m (150 ft) .| Because the strong penetration capability of the ultrasonic waves, water may get into the watches if they are not truly waterproof. Use the watch stand supplied as a precaution if not sure.
Others
Wood; coated glass, ceramic, camera filters with preexisting cracks.| Ultrasonic cleaning may enlarge the cracks pre-existed in the coating on the glasses, ceramic, and glass. If the items have no pre-existing cracks, then t is okay.

SAMPLE APPLICATIONS

DIRT ELIMINATION PROCESSES

• Many tiny bubbles are created when ultrasonic sound is passed through liquid
• Bubble are imploded constantly under the ultrasonic.
• The dirt splits into tiny particles thus separating from the item.

COMMON CLEANING METHODS

REGULAR CLEANING
Use tap water only

Cleaning Method

1. Put the items to be cleaned inside the basket and put the basket inside the tank (or put the items inside the tank directly).
2.  Add water to the cleaning tank to a level between “MIN” and “MAX” lines and above the
3. Presto de but on test desired time setting by pressing Time button.

Note : During cleaning, dirt will come off like smoke and the water will become murky over time. When “smoke” stops coming, the cleaning is basically done.

ENHANCED CLEANING

Add appropriate cleaning solutions to water
Cleaning solution can be added to enhance cleaning. Dish detergent can be used in general. Typical mixing ratio is one part of solution to ten parts of water. Once it’s done, run it with water only for another 90 seconds to remove residual cleaning solution.

USE OF OPTIONAL ACCESSORIES

BASKET
The plastic basket can be put in the direction as shown and then taken out in the opposite direction. Use the basket to clean small and delicate items. Ensure items not touching each other if cleaning multiple and delicate items.
Note : Plastic basket absorbs about 30% to 40% of ultrasonic energy hence reduces cleaning effectiveness.

WATCH STAND
Use the watch stand to keep watch body above water while cleaning wristband.
Important : For diver’s watch with depth less than 50 m (150 ft), water may get inside if watch body is submerged in the water using an ultrasonic cleaner.

OPERATION GUIDELINES

1. Remove the lid, place the object to be cleaned inside the basket then in the stainless steel tank.
   Note : Put small and delicate items with sharp edges into plastic basket for cleaning to avoid scratches. Basket will absorb about 30%~40% of ultrasonic energy hence reduce cleaning effectiveness.

2. Fill the tank with tap water. The liquid must cover the object to be cleaned, but not exceed “MAX” line. A Dry burning over 30 seconds will reduce the lifespan of machine, when the tank is empty without water. What’s worse, it will damage the machine it self some times.

3. Put the lid on, plug in the power cord.

4.  180 appears in the display window.

5. This is the default time and is good for normal cleaning.

6. Select desired time setting by pressing Time button: 180S • 2805 • 380S > 4805 • 905 7

7. Press” ” button to start the cleaning process. The timer starts to count down to zero. Note: You’ll hear buzzing sound which is normal.

8. When the timer counts down to zero, the cleaning process stops automatically and the display shows 000 .

9. If you need to end the process ahead of time, press “On/Off” button. If you need to repeat the cycle or increase the time, press Time button to select desired time then press “On/Off” button again to restart it. Important! Long cycle time will cause heat to build up inside the unit and water temperature to rise. Do not use the unit for more than 30 minutes continuously Take a 10-minute break in between to prolong the life of the unit.

10. When cleaning is done, unplug the power cord, remove the lid, pour water out in the direction shown. Wipe it clean.

11. Store the unit in a cool and dry place.

CARE AND MAINTENANCE

1. Do not turn on the unit without water in the tank. If it is turned on for over 30 seconds without water in the tank, it may damage the unit or severely reduce the life of the unit.
2. Do not run the unit for extended time or continuously. Do not run the unit continuously for over 30 minutes. Stop for about 10 minutes in between to prolong the life of the unit.
3. Do not keep water in the cleaning tank for a long time. After cleaning is completed, unplug the power cord then pour the water out through the pouring recess. Avoid getting the water inside the housing through the vents and causing damage.
4. Do not spray water over the housing. Use a towel to wipe the tank and the housing.
5. Do not expose the unit under direct sun shine for long. Keep the unit in a dry, cool and ventilated area.
