System maintenance
Maintenance at regular intervals (mandatory every
2 years) is necessary to preserve the function of
the OSKA Air Overlay alternating pressure system.
Used filters must be exchanged within this period.
Maintenance/inspection is carried out by the
producer or an authorised firm or engineer at the
client’s expense.
If the maintenance is not performed within the
first 2 years of the products life or not conducted
by an authorised firm or engineer then the
warranty claims become invalid. Damage or any
other loss of function arising from the lack of
maintenance or interferences by an unauthorised
party will also invalidate the product’s warranty.
Maintenance/inspection includes the following
procedures:
01. Replace membrane unit
02. Replace air filter
03. Replace synchronous motor
04. Conduct function test/function check
05. Sealing of case and attaching an inspection
sticker
06. Protective conductor check in accordance
with DIN VDE 0751
