Frequently Asked Questions - Emmi 280HC EMAG

What is the usable capacity of the Emmi-280 HC tank?

The tank offers a working volume of 28 liters, with a total capacity of 32 liters. The internal dimensions of the tank are 500 x 300 x 200 mm, allowing for the treatment of large parts.

What ultrasonic power does this device deliver?

The Emmi-280 HC delivers up to 750 W of ultrasonic power via 10 PZT Wide Beam transducers. The heating power is 1,000 W, for a total power of 1,750 W.

How to adjust the cleaning temperature?

The temperature range is from 20 to 80 °C, adjustable via the rotary control knob on the front panel. For most common uses (glasses, jewelry, mechanical parts), a temperature of 40 to 60 °C gives good results.

How does the timer work?

The timer is adjustable from 1 to 60 minutes. The device also has a continuous operation mode for prolonged cycles. At the end of the cycle, the device stops automatically.

How to easily drain the tank?

The Emmi-280 HC is equipped with an integrated drain tap, which avoids lifting the device (20 kg) to empty the liquid. Simply open the tap and direct the used liquid into an appropriate container.

What cleaning products should be used with this device?

Use a neutral ultrasonic detergent diluted in water (e.g., special ultrasonic products). It is forbidden to use flammable liquids, acids, products containing chloride ions, or aggressive household products, as they could damage the stainless steel tank.

What types of parts can be cleaned?

The device is suitable for professional tools, laboratory equipment, printed circuit boards, aerospace parts, jewelry, dental prostheses, and small mechanical parts. Do not place parts directly at the bottom of the tank: always use the provided basket.

Can the provided basket hold large parts?

The stainless steel basket measures 440 x 240 x 100 mm with a mesh of 12 x 12 mm. For larger parts exceeding these dimensions, they can be suspended or placed directly in the tank without the basket, ensuring they do not touch the bottom.

Is the device noisy during operation?

Ultrasonic cleaners emit a characteristic buzzing sound during operation. It is advisable not to leave your hand in the running bath and to work in a ventilated area. Wearing hearing protection is recommended during prolonged use.

What to do if the cleaning action seems insufficient?

Check that the tank contains the appropriate amount of liquid (recommended level) and that the temperature is reached. Replace the bath if the liquid is too laden with dirt. Ensure that the parts do not touch the bottom of the tank, as this would dampen the vibrations.

How to maintain the stainless steel tank?

Rinse the tank with clear water after each use and wipe with a soft cloth. Avoid abrasive products. In case of lime deposits, a short cycle with a diluted citric acid solution may help, followed by a complete rinse.

What power supply is required?

The device operates on a standard mains supply of 220-240 V / 50-60 Hz. Given the total power of 1,750 W, it is advisable to plug it into a socket protected by a circuit breaker of at least 10 A, without an insufficiently rated extension cord.

3. CONVENTIONAL USE

The equipment may only be used for the purpose as set forth in the catalogue and in the technical descriptions which means for ultrasonic cleaning as described in this instruction, and only in conjunction with external devices and components which are recommended or approved by EMAG AG. Any other use of the equipment is considered to be non conventional.

In case of non conventional use, EMAG AG will not be liable for possible damages and will not warrant for the correct and functional work of the components. Part of the conventional use is also the observance of all information given in the operating manual. To this attention is drawn by the sign on the type plate. The correct and safe operation of the equipment implies appropriate transportation, storage, installation and assembly as well as careful handling and maintenance.

4. NONCONVENTIONALUSE

In case of non conventional use of the equipment danger for life and limb as well as danger for property may occur. Therefore a non conventional use is prohibited. In case of non conventional use EMAG AG will not be liable for possible damages and will not warrant for the correct and functionally work of the components. In order to avoid non conventional use of the ultrasound cleaning equipment the following directions are to be considered:

• The equipment may only be operated with the voltage printed on the type plate on the backside/ bottom side of the housing (shockproof socket).
• No flammable or aggressive chemicals (i.e. acids etc.) must be used for operation of the equipment. If necessary, use glass container EM 50 DG.
• During operation do not touch the liquid.
• In case of transportation damage, don't connect the equipment with main source.
• Do not clean creatures (i.e. finger nails, animals etc.) in the equipment.
• The equipment must only be operated with the correct level of water (water till mark, approx. 1 cm below upper brim). This must be controlled if equipment is operated for a longer time.
• Strongly contaminated goods shall be positioned in the equipment with the contaminated side to the bottom - do not staple goods.
• The goods to be cleaned must not be positioned directly onto the bottom of the tub – use the basket.
• If the equipment is operated for a longer time, do not stay longer than 4 hours within 1m distance to the equipment.
• The equipment must only be operated indoor and within a dry environment.
• It is normal, that the upper brims warm up at longer operation.
• Before emptying the tub, the power connector must be disconnected from the main source.

The tub is filled with water – with or without cleaning concentrate – and the power connector is connected with main source. After power switch is ON cleaning time, ultrasound power and heating power can be adjusted by the rotary switches. By moving the timer switch to the left the equipment can be set for permanent operation. Permanent operation should be avoided because by evaporation of the water the equipment may run dry and may be damaged. In no case a permanent operation time of 4 hours must be exceeded.

The cleaning time to be adjusted depends on the contamination level of the goods to be cleaned. If the adjusted cleaning time is terminated, the equipment automatically stops the cleaning operation. If rotary switch is newly adjusted, the equipment starts again to operate. For stopping equipment operation use OFF switch. After termination of the cleaning operation remove cleaned goods from equipment and rinse under running water in order to remove possibly still adhered particles. After termination of a cleaning operation – or several cleaning operations – it is recommended – depending on the degree of contamination – to exchange the water (disconnect main source before exchange of water). The tub shall be rinsed and dried by a cloth. Please make sure, that no water can penetrate through the slots in the bottom of the equipment into the equipment.

Advise:

If equipment is filled with new water, please consider a reasonable time for the outgazing of the water. We recommend an operation of the equipment with water for a couple of minutes before you insert the goods for cleaning.
