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 burst 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 copper items where oxidation has darkened the items, special solutions need to be added to the water to remove the oxidation.

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, et e ok,

APPLICATIONS

Optical Stores:
Optical stores can use ultrasonic cleaners to provide valuable services. Use ultrasonic cleaner and tap water to remove the debris on the lenses, hidden in the rims and nose pads so the eye wear gets professional cleaning and care.

Jewelry Stores:
Jewelry stores can use ultrasonic cleaners to expand services.
Jewelry such as necklaces, diamond rings, rings, earrings can be cleaned with tap water to recover shine.

Mobile Phone and Electronics Service Shops
PCB renewal: Non-operational electronics, after falling into water, or non- operational key pads can be cleaned with ultrasonic cleaners and pure alcohol to recover the functions.

Watch Service Shops
Precision parts cleaning: Put small parts in a beaker made of stainless steel or glass filled with lubricant oil, then place the beaker inside the cleaning tank and add water. Ultrasonic waves will penetrate the beaker and act on the parts to make them clean.

Printing Shops
Unblocking dried printer heads o ink cartridges:
Large printers and inkjet printers often have dried printer heads o ink cartridges ports. Replacing them with new ones is very costly. Adding acetone or special cleaning solution and using an ultrasonic cleaner with a couple of minutes of cleaning will remove the blockage and make them usable again.
Avoid acetone from contacting the plastic housing to prevent corrosion. Use Indirect Cleaning explained later and a glass or metal container for acetone.

Homes:
Children and baby items: Debris left in small holes and crevices are difficult to clean by regular means. Bacteria and mold can develop at these locations. Ultrasonic cleaners can remove the debris and be combined with disinfection to achieve true cleaning.
Eyewear, watch bands, shavers, razors and other household items : Ultrasonic cleaners can be used to clean the debris between the rim and the lenses on eyewear, between razor blades, and on the metal mesh of shavers to keep the blades sharp.

SAMPLE APPLICATIONS

COMMON CLEANING METHODS

RTEGULAR CLEANING

Use tap water only
Cleaning Method:

Put the items to be cleaned inside the basket and put the basket inside the tank (or put the items inside the tank directly ).
Add water to the cleaning tank to a level between “MIN” and “MAX” lines and above the area to be cleaned. Select desired time setting by pressing Time button.
Press “On/Off” button to start cleaning.
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.
INDIRECT CLEANING

PELCAS CDS 300 Digital Ultrasonic Cleaner - Regular clening
3

Put the items in a separate container.
Use ultrasonic waves to penetrate the container to do the cleaning.
Suitable Locations:
watch and precision parts , mobile phone and electronics service shops, large printing shops.
Different industries use different fluids to be used inside the container:

Watch service shops – Watch oil (to prevent rust)
Precision electrical parts — Hexane (to dissolve grease, to evaporate quickly)
Mobile phone and electronic service shops – Pure alcohol (to evaporate quickly)
Printing shops — Acetone are often used (to dissolve ink)

Avoid acetone from contacting the plastic housing to prevent corrosion. Use Indirect Cleaning and a glass or metal container for acetone.
Cleaning Method:

Put the item inside a container. Add proper fluid to submerge the area to be cleaned
Place the container in the tank directly. Add water to a level between “MIN” and “MAX’’
Turn the power switch on. Press “Time” button to set the timer to 10 minutes. Press “On/Off” button to start cleaning. Ultrasonic waves will penetrate the container and clean the items.

OPERATION GUIDELINES

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.

Fill the tank with tap water.
The liquid must cover the object to be cleaned, but not exceed “MAX” line.

Put the lid on, plug in the power cord and turn the power switch on.

180 appears in the display window.
This is the default time and is good for normal cleaning.

Select desired time setting by pressing Time button:

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

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

If you need to end the process ahead of time, press “On/Off” button. If you need to repeat the cycle or to 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.

When cleaning is done, turn the power switch off ,open the cover, remove the items. Unplug the power cord, empty the tank by pouring out the water in the direction shown with an arrow on the unit. Avoid pouring it over the front where the control panel is located. Wipe the tank clean and remove the power plug.
Note: To avoid residue building up, always empty the tank and wipe it clean.

Store the unit in a cool and dry place.

USE OF OPTIONAL ACCESSORIES

BASKET
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.

CARE AND MAINTENANCE

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.

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.

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.

Do not spray water over the housing.
Use a towel to wipe the tank and the housing.

Do not expose the unit under direct sun shine for long.
Keep the unit in a dry, cool and ventilated area.
