This list of safety warnings do not include all possible misuse of the machine, but it describes the most predictable. The person responsible for the safety at the machine owner company must be commissioned to assess, monitor and control the use of this machine.

SET UP

1. The machine is supplied packed. Check that the packaging is in good condition before removing it. When removing the packaging, do not use sharp elements such as scissors or cutters to avoid marking the machine.
2. Use a forklift to move the machine and make sure that you use the red points of support when using a pallet and the blue ones when lifting the machine directly.
3. Distance the unit 300mm / 11.81”. or more from the walls or from other machines, since the semiconductors integrated into the generator make it temperature sensitive. The high temperature may cause malfunction.
4. Connect to a power source of appropriate voltage as indicated on the equipment. Always ensure the machine is properly grounded. See equipment specifications.
5. The cleaning tank must be placed horizontally on a firm surface and leveled.
6. The equipment must be placed in a dry place.
7. The air connection must maintain a constant pressure of 6 bars. (Recommended operating pressure).
8. The size of the water connection for filling and emptying the tank will depend on the model (See technical specifications). If there are security overflows, they must remain open.

BEFORE START UP

Personnel in charge of handling and operating the machine must have training in handling it and its inherent risks. This machine carries risks due to chemical substances, electrical elements and tires.
IMPORTANT: READ THE MANUAL BEFORE DOING ANY TASK WITH THE MACHINE.

1. Connect to a suitable electrical outlet (IMPORTANT: See equipment specifications and check the type label on the machine).

2.  Ensure that the drain valve is closed.

3. Do not operate the ultrasonic equipment without water. When the machine is started without fluid the transducers, the heating element and other components get damaged immediately.
   Ensure the tank is full before operating the equipment.

4. Fill the main tank to its maximum water level. In model with WFS up to the top of the separator connecting the main tank with the auxillary tank (see image). Fill the auxiliar tank by overflowing over the separator. IMPORTANT: Always exceed the minimum level marked. If not so, transducers and heating elements may get damaged.

5. WFS fill the auxiliary tank through the main tank (overflowing over the separator).

6. Turn on ultrasounds.

7.  Turn on heating element (recommended temperature: 68ºC / 155ºF to 74ºC / 165ºF). Be careful with the hot parts of the machine, specifically the valves located on the left side, the cleaning liquid and the parts cleaned when removed from the liquid.

8. Before cleaning any part, and every time you change the water of the tank, it is necessary to DEGAS the water. For this we must let ultrasounds work for 2 to 3 hours, depending on water hardness. We will know when the water is degassed when it stops leaving out small bubbles (oxygen molecules). When the diluted product is added to the tank, an abrupt change in water cavitation can be appreciated for about two minutes. Then the bath is ready to work. Whenever we add water by accumulated losses when parts are taken out or by evaporation, it is important to add the product in the same proportion.
   The percentage of the product to be mixed with the water will depend on the type of product (see technical data sheet of the product purchased).

9. The ultrasonic unit comes with built-in programming. However, it can be changed.

10. Do not place parts, cleaning baskets, or cups directly on the bottom of the tank (on top of transducer box). This is a common cause of defects in vibration, and also shortens the life of the transducer.

11. Immerse the parts to be cleaned in the cleaning tank gently, taking special care not to hit the base or other components. These incidents can damage the parts or shorten the life of the transducer.

12. The bath will be effective for longer if we carry out oil extractions and water filterings. There is no provisions for water and product exchange as it depends on the quantity of cleaning performed and the degree of contamination of parts washing time.

13. Performing extractions of oil and filter the water bath will last longer. As with changing the bath, there is not a stipulated periodicity of the filterings and oil extractions because it depends on the parts to be washed and dirt. This frequency should be assessed by the staff in charge of the equipment.

14. When the platform is down, the cover must be closed before proceeding to the cleaning process.

15. When the cleaning is finished, let the piece drain to avoid risks of dripping. Make sure it does not drip before removing from the platform.

Setting up and initial operations must only be carried out by CRYSTAL CLEAN personnel. At the time of installation, a representative of CRYSTAL CLEAN will conduct a demonstration and give all the explanations deemed appropriate. Installation and commissioning carried out by unauthorized personnel can cause damage to both operators and the machine.

THE USE AND MISMANAGEMENT
The machine is designed for the operator to work at the front, except for maintenance works where you can access the machine where necessary. When the cleaning is done,the pieces will be at an elevated temperature, it is necessary to use thermal protection gloves for handling. Do not put into the machine parts with a higher volume than 30% of the total tank volume. Do not insert parts whose measures and/or weight are greater than described in the specifications. You should not work without adequate water level. To drain the machine it is necessary to wait until the cleaning liquid has decreased in temperature in order to avoid thermal contact damage. Insert the parts to be cleaned in the tank free of flammable liquids.

ATTENTION: WHEN THE WORKING HOURS ESTIMATED HAVE BEEN ACCOMPLISHED , IT WILL APPEAR A MES-SAGE ON THE MAIN SCREEN WARNING ABOUT THE MAINTENANCE TASK TO FOLLOW. SEE MAINTENANCE SECTION.

WATERFLOW SYSTEM

(IF INCLUDED)
With this system, through the pump (described in section 8 of the previous section), a circulation is created in the fluid that entrains all the oil and other residues that are on the surface to an auxiliary tank.

With the valves in the open position the pump works to remo-ve the oil from the main tank to the auxiliary tank. This is the normal position that the machine should always have.
To extract the oil from the auxiliary tank, proceed as follows:

• Open the drain valve and install a bucket for the drainage of the oil. This operation is most effective by applying it with low flow rate in the injection. (This valve must always be closed in case it is not performing this operation)
• Inject water (very slowly) through the valve located in the lower part of the equipment (The amount of oil that comes out will be smaller the less the injection of water into the tank).

AIR PRESSURE REGULATOR
(IF INCLUDED)

In the equipment there is the possibility of regulating the pressure of the compressed air (see the manometer) of the pneumatic system of the platform or any other system that requires air.

ADJUSTING THE SPEED OF THE PNEUMATIC CYLINDER
(IF INCLUDED)

By adjusting the regulators it is possible to change the movement speed of the plataform. This zone indicates the maximum weight that can be raised with this machine.

BAG FILTER TTF1 AND TTF2
(IF INCLUDED)
Filtering process of the cleaning liquid to reduce contamination. Regular checking and emptying of the filter bag and its cleaning are recommended. When the filter gauge exceeds 1 bar, empty the reusable bag. Every time the filter is opened, to return to operation it must be purged through the valve located next to the manometer. Orient the valve hose to the main tank or a can.

To change the filter bag, you must open the filter cover, close the outlet (to the tank) and inlet (to the filter) valves and drain it through the drain valve. Replace the bag and leave everything as at the beginning and purge.

Do not drop small objects into the tank, they may reach the pump and damage it.
Attention: do not open the filter when hot to avoid injuries.

MAINTENANCE

Maintenance of the machine should only be carried out by CRYSTAL CLEAN personnel. If the machine requires fur-ther cleaning or shortening service intervals, please contact your CRYSTAL CLEAN delegation. Any incidents or break-downs should only be repaired by a CRYSTAL CLEAN sales and service representative.

CLEANING LIQUID
It is necessary to periodically replace the used cleaning liquid. It may happen that particles deposited on the bottom of the cleaning tub will clog transducers, resistance and other components, thus causing losses in the quality and intensity of cleaning and reduction of the life of the transducers. This interval for water change depends on the intensity of use of the machine, both in time and in the degree of dirt of the parts to be cleaned.

• IT IS RECOMMENDED TO CLEAN THE TANK PERIODICALLY

ULTRASOUND EMITTERS
The surface of the emitter erodes after many years. It is necessary to examine it with each change of water before use. When it is seriously eroded, holes appear on the surface, which in case of penetrating the plate will allow water to enter the interior of the emitter and will generate a fault. Clean periodically by taking advantage of water changes. The inside of the tank is cleaned using a water hose. It is necessary to use the cleaning products recommended by CRYSTAL CLEAN , in order not to cause damage to the parts to be cleaned or to the ultrasound equipment itself. Each machine will use a product adapted to the specific application that is needed. CRYSTAL CLEAN will supply the data sheet of the products to be used.
IMPORTANT: NEVER clean them if they are at high temperature. Allow to cool and rinse together with the bottom of the tank. If you want to expedite the process, empty the hot water tank while mixing with cold water so that the temperature gradually drops. This is done to avoid a sudden change of temperature in the emitters (Ultrasound boxes).

GENERATORS
Clean it once a month with a compressed air gun using the safety glasses. If the dirt that is generated at the site where the equipment is located is extreme (eg suspension of particles such as chip powder, paint suspension, polishing powder in suspension, etc.). They will be cleaned more often. DO NOT clean with organic solvents such as solvent, alcohol, or kerosene since the paint coat of the generator may deteriorate or even deform the plastic components of the equipment.

Way of acting:

• Open the back of the unit. Remove the filters from the generators (in the case of models with filters), located at the rear. Blow with air gun (make sure no water gets out with air).
• Blow the generators.
• Mount the filters of the generators.
• Replace the rear panel that has been removed to access the generator.

ELECTRICAL CABINET
Clean the inside of the cabinet with air gun every 1-3 months depending on the accumulated dirt. If the work environment is too dirty, do so at shorter intervals. Whenever the air gun is used it is necessary to use the safety glasses.

HEATING ELEMENT
Check cleaning at each water change. If it is covered by sludge, a fault can occur. It can be cleaned using a water hose.

LEVEL PROBE (if included)
Check the cleaning of the level probe every water change. Sludge or other types of dirt may be present in the probe housing. Be sure to remove any items and clean using a water hose.

SCREEN
Do not use with wet hands or chemical residues. Clean with a cloth and mild soap when necessary. Cleaning with other more aggressive chemicals can cause irreparable damage to the screen.

PNEUMATICS (if included)
Bleed the regulator filter if necessary Check that the air supply is free of moisture. If moisture enters the pneumatic circuit, the solenoid valve and cylinder can be damaged.

WATERFLOW SYSTEM (if included)
Cleaning the auxiliary tank with each change of water. It is often impregnated with oil that in some cases is dried and accumulated both in the bottom and in the extraction bowl. Clean the filter inside the tank in turn. This can be unscrewed to clean outside of the machine.

FILTERING SYSTEM (if included)
Verify the pump is operating properly taking advantage of the water changes. Clean the filter periodically using the drain valve. Check that the filter bags are in good condition, not broken. Check the gasket. All these operations must be done at a temperature below 104 ° F.

Maintenance periods for standard cleaning:

• Cleaning liquid change: When poor or longer cleaning is observed.
• Check surface emitter status: Each water change
• Emitters cleaning: Each water change.
• Generator cleaning: 1-3 months depending on environmental conditions.
• Electrical cabinet cleaning: 1-3 months depending on environmental conditions.

ELECTRICAL AND PNEUMATICS SCHEMES

RISK ASSESMENT

This equipment has built-in ultrasound emitters inside the tanks. Ultrasound are acoustic waves whose frequency is above the hearing capacity of the human ear (approximately 20,000 Hz). Ultrasonic cleaning is a method that uses ultrasounds (generally 15-2000 kHz) and an appropriate cleaning solution. The ultrasonic frequency in this type of work is low. The health effects of ultrasound, as included in the Technical Note of Prevention 205 are the following:
By contact: mainly manifested in the hands, in cleaning and degreasing operations. There is no such exposure, since the transmission medium is aqueous, that is, the water acts as a shield, with which the transmission of ultrasounds is practically non-existent.
By air: same as the previous point.
Every cleaning operation with this equipment is made with the lid closed, so there is no exposure to ultrasound. In case of auditory discomfort it would be advisable to use adequate protection (plugs, etc.), although the noise emission values are below the maximum admissible.

Risks that could not be eliminated are analyzed below:

Risk of thermal contact with hot parts of the machine, the cleaned part or the cleaning liquid. The risk is duly signposted on the machine at the exit of the cleaning liquid and the use of heat protection gloves is indicated in the users manual.| 1| 2| 1| 1| 4| 1| 1
Risk of contact with chemical products (cleaning fluid). In the users manual, is indicated that it should be considered the cleaning products safety data sheets and the use of chemical protective gloves.| 1| 2| 1| 1| 4| 1| 1
In the user manual it is indicated that the piece, once cleaned, is left in the basket until the liquid is drained.| 1| 2| 1| 1| 4| 1| 1
Risk generated by the transfer of flammable liquids to the cleaning liquid. The users manual indicates that it is necessary to make sure that the part to be cleaned is free of flammable liquids.| 1| 2| 1| 1| 4| 1| 1
