SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Unplug Miniflex before changing filter or replacing carbon brushes.

------------------------------------------------------------------------

ROUTINE MAINTENANCE

•The aluminum collection pan should be inspected, cleaned and emptied on a monthly basis.

•The pre-separator (located on the bottom of the main filter) should be inspected and cleaned on a monthly basis, using an industrial vacuum cleaner.

•The pre-filter should be inspected and cleaned on a bi-monthly basis, using compressed air or an indus- trial vacuum cleaner.

•Frequency of cleaning and emptying depends on a number of factors such as the type of welding process and the frequency of use.

•The main filter should be checked every month to ensure that there is no damage.

•The seals of the main filter should be checked every 12 months.

Refer to Figure D.1 on page D-3 for the following instructions.

EMPTYING THE ALUMINUM COLLECTION PAN

1.Remove electrical cord of Miniflex unit from electri- cal outlet.

2.Loosen the side clips (A).

3.Remove the top cover (B) from the machine.

WARNING

The particulate matter collected in the unit may be dangerous to your health. Take necessary precau- tions so that you and your fellow workers do not breathe dust and particulate. Wear a suitable respirator when disposing of the particulate. Follow local Environmental regulations for disposal of filters and particulate matter.

----------------------------------------------------------------------

REPLACING THE FILTERS

The main filter and the HEPA filter cannot be cleaned and therefore they have to be replaced periodically. It is recommended to replace all filters at one time.

WARNING

A saturated filter often contains dust and dirt particles which could form a health hazard upon inhalation. When replacing the filters, always wear a high-quality and approved face mask or respirator. Wrap the filters in a properly closed plastic bag and dispose of it in compliance with local regulations.

----------------------------------------------------------------------

Replace the filters in case of damage or when the extraction capacity has become insufficient due to the amount of particulate in the filter.

Periodic check of filters is required to maintain optimal performance and life of unit. Filter performance/life is dependent on variables such as:

-Welding application/processes -Oil involved in weld processes -Dust/grinding particulate -Proper usage and maintenance

Note: There is no filter clog indicator on this machine model.

Refer to Figure D.1 on page D-3 for the following filter instructions.
