Repairs: Repair work may only be carried out by authorised persons.
•
Maintenance: The device must be checked by an authorised person as and
when necessary (once a year as a minimum) in accordance with TRbF 20
Section 15.4. The filters must be replaced or cleaned at the same time.
Replacement filters can be ordered from the supplier. We recommend
stocking a set of replacement filters to avoid interrupting operation. The
device records the operating time internally and outputs an audible signal
(one 3-second beep every hour after 365 days) to indicate that maintenance
is due.
