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 cartridge fi lter must be taken out and checked for degree of contamination, and damage to seals.
If the cartridge fi lter is found to be damaged or badly contaminated, you must replace.
Items that can not be satisfactorily cleaned (e.g. fi lter) 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 staff and others.
Suitable precautions include decontamination before dismantling, provision for local fi 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 qualifi ed person must perform at least once a year - or more frequently if national requirements dictate
- the fi ltering effi ciency of the fi lter cartridge must be checked, or the fi lter cartridge must be replaced, a
fi lter inspection to look for signs of damage, checking the tightness of the machine and correct operation
of the control mechanism.
Also the fi ltration effi ciency should be tested at least annually, or more frequently as specifi ed in
national requirements.
The test methods that can be used to verify the machine's fi lter effi ciency are specifi ed in EN 60335-2-69
Annex AA (AA22.201.2). If the test fails it should be repeated with a new cartridge fi lter.
