D-1 MAINTENANCE D-1
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.
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
