Installation / Removal / Disposal of the dust bag.
The dust bag holding the dust and debris must be removed and renewed by authorised personnel
only, wearing appropriate personnel protective equipment, in a specied de-contamination area.
Never operate without the full ltration system in place.
Process of disposal: Disconnect the hose, t the Dust Cap on the Hose Flange, un-clip the bottom
two Toggle Clamps (Upper two toggle clamps have split pins that should not be removed by
un-authorised personnel).
Remove the cloth lter (A) in the Drum. Remove the dust bag from the Hose Flange inside the
drum and seal the Dust Bag hole. Place the Dust Bag inside an impervious plastic bag and seal
the bag.
Dispose of the plastic bag, depending on contamination, in an appropriate manner.
Fit a new Dust Bag over the Hose Flange inside the drum assembly. Fit the cloth lter (B), and the
Head, plus Interceptor assembly, re-applying the two Toggle clamps.
MAINTENANCE
All machine parts should be regarded as contaminated when removed from the hazardous area
and appropriate action taken to prevent dust dispersal.
Disconnect from the power supply during cleaning, maintenance or when replacing parts. Ensure
the plug is removed from the socket outlet.
Maintenance must be carried out in a suitable non hazardous area with facilities for cleaning the
area after servicing, and with suitable ventilation.
Maintenance and cleaning work must always be carried out by competent authorised personnel
equipped with suitable personal protection.
The Cloth lter must be taken out and checked for degree of contamination, and damage to cloth
or seals.
If the Cloth seal is found to be damaged or badly contaminated, you must replace. If only mildly
contaminated, either wipe clean or wash with a mild detergent (ensure it is dry before replacing).
Items that can not be satisfactorily cleaned (e.g. lters) need to be disposed of in an impervious
plastic bag and disposed of in accordance with current regulations. Replace the items that cannot
be satisfactorily cleaned using approved manufacturer parts.
Regularly examine the supply cord for damage, such as cracking or ageing. If damage is found,
replace the cord before further use.
All parts of this vacuum are safety critical only replace with the genuine Numatic spare parts.
For user servicing, the machine must be dismantled, cleaned and serviced, as far as is
reasonably practicable, without causing risk to maintenance sta󰀨 and others.
Suitable precautions include decontamination before dismantling, provision for local ltered
exhaust ventilation where the machine is dismantled, cleaning of the maintenance area and
suitable personal protection.
In class H machines the outside of the machine should be decontaminated by vacuum cleaning
methods and wiped clean or treated with a sealant before being taken out of the hazardous area
and appropriate action taken to prevent dust dispersal. (HSE Risk Assessment needed).
A competent person shall perform a technical inspection at least annually, consisting of, for
example, inspection of lters for damage, air tightness of the machine and proper function of the
control mechanism.
Also the ltration e󰀩ciency should be tested at least annually, or more frequently as specied in
national requirements. The test methods that can be used to verify the machine’s lter e󰀩ciency
are specied in EN 60335-2.69 Annex AA (22.AA.201.2). If the test fails it should be repeated with
a new essential lter.

16
Replacing HEPA lters process:
Unclip the top two toggle clamps, removing the security split pins in advance.
Remove the Head assembly and place in a safe area. Unclip the lower two toggle clamps and
remove the Interceptor assembly from the drum assembly, and place the Interceptor on a good
level working surface.
Unscrew the 6, M5 x 10 screws on the underside of the Interceptor assembly which will expose
the HEPA lter.
Remove the contaminated HEPA lter and place in a suitably impervious plastic bag and dispose
of in accordance with current regulations. Replace the HEPA lter with an identical approved part
(ensure plastic lter grid that locates into the hole in the metalwork is not thrown away with HEPA
lter).
Re-assemble the Interceptor assembly in reverse order. If the seal between the upper and lower
metal parts of the Interceptor assembly is damaged, replace with a manufacturer approved seal
material (there must be NO gap in the circular seal).
Re-assemble the machine in reverse order (Screw torque 2.5Nm). Ensure new split pins are tted
and legs opened.
During this process please look carefully at all seals between mating parts and check for any
damage.
If seals have been damaged, please contact the machine manufacturer to obtain an approved
replacement part.
