Washer-disinfector with active drying and short operating times

The MELAtherm 10 is a washer disinfector complying with the EN 15883 European Standard. It is ideally used in processing instruments by machine.

With compact external dimensions, the MELAtherm 10 offers full features without any additional charge:

  • Feeding process agents  with the dosing unit
  • Batch documentation with the CF card or network
  • Active drying in accordance with the EN ISO standard

MELAtherm 10 automatically monitors the rotation of the rinse arms, the rinse pressure and the filter sieves. Errors in the program mode or during operation are thus prevented. MELAtherm 10 can be fitted in floor units without any problem, the standard width being only 60 cm.

Should the MELAtherm 10 be free-standing next to the floor unit, MELAG offers a stainless steel cover plate. The optional floor unit, also available, facilitates ergonomic working height and creates additional storage space. MELAtherm 10 is equipped with a basis basket, with or without injector rail, at your option. Up to 11 hollow body instruments can be processed with the injector rail, e.g. suction tubes or dental handpieces and contra angles.

  • Washer disinfector
  • Active drying
  • Built in water softener
  • Integrated process agents storage and dosing unit
  • Integrated process monitoring of spray arm rotation and spray pressure
  • 5 programmes

How often should you perform the protein residue test?

HTM states that this must be done on a weekly basis, however always consult the manufacturer as they may request different requirements. In regards to the Melag MELAtherm 10 this should be done monthly. 

How often should you perform the cleaning efficacy test?

HTM states that this must be done on a quarterly basis, however always consult the manufacturer as they may request different requirements. In regards to the Melag MELAtherm 10 this should be done monthly.

How long should your detergents last before they need to be changed?

In respect of the Melag MELAtherm 10 they should last approximately, depending on water quality, cleaner: 180 cycles, neutraliser: 600 cycles and rinse aid: 600 cycles.  

How often should you download the data from the data logger?

This will be down to your individual needs. Your data logger will hold more than 7 year’s worth of data so a constant back up is achieved. It is good practice to try and download the data on a weekly basis so that the practice has a back up on a central PC for inspection purposes.

  • Have maintenance carried out only by trained engineers.
  • Maintain the specified servicing intervals.

For retention of value and functional reliability

Regular maintenance is vital to ensure reliable operation and value retention of the MELAtherm®10.

All function and safety-relevant components and electrical units are checked during maintenance and replaced where necessary. Maintenance is performed in accordance with the MELAtherm®10 maintenance instructions.

Maintenance intervals

Have the maintenance regularly carried every year or after 1000 cycles. The MELAtherm®10 will issue a maintenance message at the relevant time.


Cleaning

The coarse and fine filter in the base of the washing chamber serves to hold back dirt particles or residue which has been cleaned from the instruments. As a result, the filters can become blocked over time.

  • Check the coarse and fine filter on a daily basis and where necessary, clean it under running water.
  • Turn the coarse filter to its fullest extent leftwards and remove upwards.
  • Release the fine filter by releasing the knurled nut and remove. If necessary, clean both filters under running water and remove any residue with a soft brush. Do not use any rinse agent.

Image

Warning: Ensure that the coarse and fine filters are always in place before programme start. Failure to observe these provisions can result in the accretion of residue in the cleaning cycle and restrict the functionality of the MELAtherm®10.

Fine dirt particles can block the nozzles of the rinse arms.

  • Remove the rinse arms and if necessary, wash out the nozzles under running water.
  • Loosen the curled nut and remove the upper and lower rinse arms upwards and downwards respectively.
  • Clean very blocked nozzles with a thin pointed object.

Image

  • Return the rinse arms and ensure their free movement.

Control the door seal on a daily basis

  • Check the door seal for impurities, deposits or damage on a daily basis.
  • Clean any impurities with a damp, non-fuzzing cloth and a commercially available neutral liquid cleaning agent.

Injector rail nozzles

  • To test whether the nozzles on the injector rails are blocked, they must be held upright under running water.
  • If the water flows through freely, then the nozzles are not blocked.

Exterior front of the device

  • The operating unit and the plastic front of the MELAtherm®10 should only be cleaned using a damp cloth or a suitable plastic cleaning agent.
  • Ensure the use of a suitable material. Never use solvents or cleaning alcohol.

Check pump pit and non-return valve

Any fine particles having passed through the coarse and fine filter into the water cycle should be removed. This is observable if the flushing water cannot be pumped away after a programme has finished.

  • To do so, control the pump pit 1 by removing the coarse and fine filter beforehand. Remove any residue / deposits.
  • Pull the non-return valve upwards and remove it from the pump pit. If necessary, clean it under running water.

Image

  • If necessary, start the "Rinsing” programme to wash away any particles thus removed.

Should this occur repeatedly, call our service team upon the next maintenance interval.


Changing the HEPA filter in the drying fan

Exceeding the permissible level of blockage can result in a worsened drying outcome. For this reason, MELAtherm®10 checks the degree of blockage automatically. Exceeding the tolerances results in the issue of the relevant display message.

Image Image Image
1. Pull the drawer outwards.

2. Loosen the bayonet cap on the cover cap by turning it and lift up the cover cap.

 4. Remove the HEPA filter upwards and   change it.

 

3. Remove the pre-filter upwards and change it.

 5. Replace the cover cap and fasten the      bayonet cap.

Ensure that the blades of the HEPA filter are not damaged when setting in. The HEPA filter should only be touched on its edges.

Failure to observe this provision can result in damage to the HEPA filter and restrict its effectiveness. This could result in recontamination of the disinfected instruments.

The pre-filter and HEPA filter should be changed yearly (e.g. during maintenance).


Avoiding the development of stains

 

Stains from poor water quality

Stains on the instruments or the MELAtherm®10 can develop from poor water quality.

To avoid the development of stains on the instruments or the washing chamber, we recommend a final rinse with deionised water (DI water).

Stain development from extraneous rust

All water conducting components of the MELAtherm®10 are made of rustfree materials. This rules out the development of stains or rust caused by

the MELAtherm®10.

The development of rust is always extraneous rust. Often, an instrument which drops rust can suffice to cause the development of rust on another

instrument or in the MELAtherm®10. Poor water quality containing heavy metal or chloride can result in the development of stains or rust.
