10.0 CLEANING AND MAINTENANCE
FILTER BLOCKAGE WARNING LIGHT:
A filter blockage warning light is installed on the vacuum cleaner. The light turns on to indicate
a loss of suction. In such case the collection bag may be full, cloth filters (main filters and safety
filters) may need to be washed or HEPA filters may need to be replaced.
WARNING: When the filter blockage warning light turns on, turn the vacuum cleaner
off as soon as possible as filter blockage cause the temperature inside
the vacuum cleaner to rise and can also lead to motor damage.
IMPORTANT: We recommend proceeding with the following maintenance after each
use and after a maximum of 8 hours of consecutive use
WARNING: Turn off the vacuum cleaner and disconnect the power cable before
performing any servicing or maintenance of the vacuum cleaner.
a. Shake the cloth filters regularly using the manual filter shaker handle to dislodge caked-
on dust
b. Dispose of collection bag when full and replace by a new collection bag
c. Empty and clean the recovery tank.
WARNING: Empty the recovery tank when necessary but also after every use (8
hours shift). Do not allow recovered materials to sit for extended periods
of time. An excessive accumulation of recovered materials can create a
dust ignition hazard.
d. It is recommended that the cloth filters be cleaned regularly. Dirty cloth filters will reduce
the airflow through and reduce the performance of the vacuum cleaner. The cloth filters
(main filters and safety filters) can be washed with warm water (no detergents required).
IMPORTANT: After washing the filters, make sure that they are completely dry
before reinstalling them in the vacuum. Do not reinstall the cloth
filters if they are still wet.

Page 16 of 27
e. The cloth filters should be replaced every two or three years depending on use.
f. Inspect the cloth filters regularly. If the cloth filters are torn, replace immediately. A torn
filter will allow dust and other materials to enter the motor and may cause pre-mature
wear of the motor
g. Clean hose to remove any accumulated dust, debris or material recovered.
h. The HEPA filter should be replaced yearly, or every two years, depending on the use.
WARNING: Do not use the HEPA filter after removal out of the appliance.
WARNING: Keep the power supply cable clean and inspect it regularly for cuts
or cracks
WARNING: When carrying out service or repair operations, all contaminated
items which cannot be satisfactorily cleaned, are to be disposed of;
such items shall be disposed of in impervious bags in accordance
with any current regulation for the disposal of such waste;
WARNING: Clean regularly the vacuum cleaner surfaces with a water damped
cloth to avoid dust accumulation which could create a potential
source of ignition.
11.0 ASSEMBLING AND REPLACING THE HEPA FILTERS
A HEPA filter is designed for filtration of ultra fine particles. A clogged HEPA filter will reduce
the air flow thereby reducing the vacuum’s performance thus requiring replacement.
The life of the HEPA filters depends greatly on the use of the vacuum cleaner. It is
recommended that the HEPA filters be replaced once a year if the vacuum is used intensively
(daily). The filters can be replaced everytwo years if the vacuum cleaner is used lessfrequently
(two or three times per week)
WARNING: If the vacuum cleaner is used for the recovery of toxic materials proper
clothing and the use of an appropriate breathing apparatus is
necessary when servicing the HEPA filter housing or any other
contaminated part of the unit.
