VTUSCT5

ITEMS NOT SUITABLE FOR ULTRASONIC CLEANING

Soft jewellery:pearls, emerald, ivory, coral, agate, sea turtle shells etc...	As these items are soft, scratching may occur during the cleaning process.
Welded, plated, glued items	Ultrasonic cleaning may increase the gaps inside welded joints, plated coating or glue which may lead to breaking loose.
Watches:unless diving watches with depth rating over 50m (150 ft)	The strong penetration capabilities of the ultrasonic waves may cause water to penetrate weaker sealed watches.
Other:glass, ceramic, camera filters with known cracks	Crack size may be increased by the ultrasonic waves.

4. Features

• for cleaning of: jewellery, dentures, eyeglasses, electric shaver heads, CDs/VCDs/DVDs etc.
• 2 colour LED display: 1 to 30 minute timer
- cooling fan
- ceramic heater
• overheating protection

5. Working principle

The principle behind ultrasonic cleaning is cavitation.

When the ultrasonic cleaner is switched on, 3-dimensional sound waves of alternating positive and negative pressure are generated and transmitted into the water in the tank. These sound waves created micron-sized bubbles that grow and build up energy during negative pressure and implode at a very high speed during positive pressure (43,000 times per second). These implosions of high energy bubbles create cavities that literally pull contaminants of the surface (at speeds up to 400km/h). Due to the size of the bubbles, they are effective in removing contaminants from the smallest of crevices but harmless to the substrate itself.

Usually water is used as cleaning agent as it is inexpensive and environmentally safe.

Note: degassing process

When cleaning heavily soiled or greasy items or silver, copper or brass items, chemical solutions need to be added into the water. The solution might form many small droplets and take a long time to dissolve in the water. Newly added water may generate many air bubbles on the tank walls. These will reduce the cleaning effect: in the beginning phase of ultrasonic clearing.

Turning on the degas function will dissipate the droplets and the air bubbles, usually in 90 seconds, and improve cleaning efficiency.

7. Operation

Refer to the illustrations on pages 2 and 3 of this manual.

1. Open the lid [A] as illustrated, put the items in the basket [F] then put them in the cleaning tank [C]. Do not overfill the basket and make sure the items don't touch each other to prevent scratches from rubbing.

Add water to a level between MIN and MAX and above the item (s) to be cleaned. When desired, add some dishwashing liquid.

Note: indirect cleaning

- Place the objects in a small container (not included, e.g. glass jar, metal box...) and fill this container with fluid so the items are submerged. Possible fluids include: hexane ('o dissolve grease), acetone (to dissolve ink), pure alcohol (quick evaporation), watch oil (prevent rust), rubbing alcohol (clean and disinfect), ...

The selected container will absorb part of the ultrasonic energy which reduces the cleaning effect:

container	absorbs
plastic	30%
aluminium	20%
stainless steel	8%

- Place the small container inside the stainless steel tank [B], do not use the basket [F]. Add water making sure the level is above the MIN indication but water doesn't flow into the small container.

Do not run the device without sufficient water inside the tank to prevent irreversible damage to the VTUSCT5.

1. Connect the power cord [H] to a mains outlet. The status indicator [1] turns green and the LED display shows:

This is the most common timer setting and working state. If the timer needs to be adjusted, press the TIME button [8] and button [9]. The timer can be set between 1 to 30 minutes.

Note: do not set the cleaning time too long as this might lead to loosening of screws, cracks or coating peeling off.

1. Press the On/Off button [2] to start cleaning. A buzzing sound can be heard from the cleaning tank and the normal cleaning indicator [5] is lit, indicating the cleaning is in progress. Closing the lid [A] will reduce the noise level.

The digital timer [7] will count down to show the remaining cleaning time. When it displays 00:00, the cleaning is done. To stop cleaning at any time, press the On/Off button [2]. The unit is designed with overheating protection to avoid extended and continuous operation for too long. When the red light [1] is on, the unit will not turn on. The unit will idle for about 20 minutes and can be restarted after the green light [1] comes on.

1. When the heater is needed, press the TC button [10]; the heater indicator [6] flashes to indicate that the heater is turned on. When the water reaches 60^ C, the heater and heater indicator [6] turn off.

Note: to ensure safe operation, the heater is turned off automatically after 45 minutes.

To speed up mixing and use less solution, use the degas function. Press the Time button [8] to set the timer to 10 minutes then press the function button [3]; the heater indicator [6] illuminates. Press the On/Off button [2] to start degassing. The VTUSCT5 returns to normal cleaning automatically after 90 seconds.

When debris "smoke" is no longer visible, cleaning is done. If additional cleaning is needed, reset the timer and repeat the steps above.

VTUSCT5

1. When cleaning is completed, switch off the VTUSCT5, unplug the power cord [H], open the lid [A] and retrieve the basket [F] and the items. Rinse and dry the items.
   Drain the dirty water via the drain groove [C]. Clean and wipe the tank dry. Do not use abrasive or corrosive solutions.

8. Care and maintenance

Refer to the illustrations on page 3 of this manual.

1. Do not turn on the unit without water in the tank.

Even though the unit is designed with multiple protections, if it is turned on for over 15 seconds without water in the tank, it may damage the unit or severely reduce the life of the unit.

1. Do not run the unit for extended time or continuously.

The unit is designed with overheat protection. If the unit has been running for 45 minutes, it is recommended to stop the unit for about 20 minutes to prolong the life of the unit.

1. Do not keep water in the cleaning tank for a long time.

Remove the water from the tank after each use to prevent the tank from corroding. Clean and wipe the tank dry.

1. Do not spray water over the housing.

Use a towel to wipe the tank and the housing dry.

1. Do not expose the unit under direct sun shine for a long time.

Keep the unit in a dry, cool and ventilated place.
