d. Saveairowtomemory

There is an ability to save a selected airow to memory so the device will revert

to the last known speed on power-on. The last known speed can be saved to

memory by holding the ON/OFF (1) and ‘-‘ (3) buttons for three seconds. To

revert to factory settings and to clear the air speed memory the ON/OFF (1) and

‘+’ (5) buttons are held for three seconds.

e. HEPAFilterreplacementtest

The HEPA lter replacement test indicator is for information purposes only.

The lter replace button, for testing the lter back pressure, is on the furthest

right-hand side of the panel. Upon pressing the lter back pressure test, the

device shall override the air ow setting to speed 5 air ow for testing the

lter for a period of approx. 30 seconds. The test button shall remain backlit

illuminated blue LED while the device is testing the air pressure.

The device will indicate that the HEPA lter needs to be inspected for

replacement by illuminating the test button in orange or a continuous LED light in

orange.

The device will indicate that the HEPA lter does not need to be inspected by

illuminating the test button in green or a continuous light in green.

Novaerus recommends replacing the HEPA lter every twelve-month (12) period

to ensure optimal performance, or when the lter test check output indicates to

do so; whichever comes rst. Discoloration on the HEPA lter may indicate that

the lter has exceeded its life expectancy. The expected lifetime of these lters is

approximately twelve months (12) under normal clean air conditions (such as that

of a hospital ward).
