Maintenance UK
It is a legal requirement, under regulation 9 of the COSHH
regulations that all local exhaust ventilation systems are
thoroughly examined and tested at least once every 14
months (typically carried out annually). The approved code
of practice recommends that a visual check should be
carried out at least once a week.
COSHH requires the annual inspection and testing to be
carried out by a competent person and specifies that
documentation results are recorded in a log.
Contact the seller for more information about inspection
and certification.
Maintenance General
User maintenance is limited to cleaning the unit and filter
replacement, only the manufacturers trained maintenance
technicians are authorised to carry out component testing
and replacement. Unauthorised work or the use of
unauthorised replacement filters may result in a potentially
dangerous situation and/or damage to the extractor unit
and will invalidate the manufacturer’s warranty.
Cleaning the unit
The stainless steel units should be cleaned with a
proprietary stainless steel cleaner, in accordance with the
manufacturer’s user instructions
The powder coat finished units can be cleaned with a damp
cloth and non-aggressive detergent, do not use an abrasive
cleaning product as this will damage the finish.
The cooling inlets and outlets should be cleaned once a year
to prevent build-up of dust and overheating of the unit.
Replacing Filters
The iQ system constantly monitors the condition of the
individual filters. As the filters block the LCD display will
show the relevant filter symbol filling up. (see section
1
for
LCD details) Each filter symbol fills up in 5% increments,
when the filter icon is filled that particular filter will need
replacing.
Pre Filter blocking Combined Filter Blocking
A log of the changes should be maintained by the user.
The filters require attention when the display shows the
filter blocked icon/ filter output signal (if fitted) or when the
extractor no longer removes fume efficiently.
All filters are tested to BS3928. A certificate of conformity
for each filter is available on request.
It is recommended that a spare set of filters are kept on site
to avoid prolonged unit unavailability. Part numbers for
replacement filters can be found on the filters fitted in your
system. Alternatively, refer to the spare parts table in this
manual.
To prevent overheating, units should not be run with a
blocked filter condition, or with dust obstruction of Inlets /
Outlets.
75% filter blocked indication
When the filters become 75% blocked the buttons on the
front of the extraction unit will turn from Green to Amber
and if fitted the iQ system will output a signal to indicate
this. At this time it is recommended spare filters are
available as a change may be needed shortly.
