7. Fault Finding
The
VENTURI
MINO power unit features audible and graphic indicators to alert when user
intervention is required. Once corrective action has been taken the alert will self-cancel and normal
operation will resume. The display screen will toggle between the alert graphic and the instruction to
refer to the user manual for more information (Fig. 4). The illuminated display and sounder will persist
whilst the alert state is active (NB. Tilt indicator is a graphic alert only, not audible). Should an alert
persist or immediately re-occur, contact Direct Healthcare Group. All sounders can be silenced and
messages cleared by pressing and holding the RUN/STOP/UNLOCK button to switch the power unit off,
whilst corrective action is taking place. The time period before the alert is indicated is shown in italics.
NO CANISTER
(Fig. 5) (
immediate
) – indicates canister is missing or is not correctly fitted. The power unit will fail
to operate whilst this message is displayed. Check that canister is correctly located and secured, as detailed on page 5.
CANISTER FULL
(Fig. 6) (
60 secs
) – indicates that the canister is full and should be removed/replaced, as detailed
on page 6. The power unit will cease to run until corrective action has been taken.
CONSTRICTED TUBE/LOW FLOW*
(Fig. 7) (
31 mins
) – indicates tube blockage/constriction or state of low
flow. Check that low flow is not caused by pinched or bent tubing. If exudate is pooling in the wound bed, the dressing
should be changed. This alert will self-cancel after 5 minutes and will re-occur if the condition persists. NB. This alert
may arise under normal operation if the wound exudate levels are very low.

CHECK DRESSING*
(Fig. 8)
/ DISCONNECTED TUBE*
(Fig. 9) (
6 mins
) – indicates vacuum pressure has
fallen below minimum allowable levels, due to either a leak in the dressing or a tube disconnection. The power unit
will continue to run whilst this message is displayed. Check that wound dressing is completely sealed and that all
tubing connections are secure..
TILT
(Fig. 10) (graphic alert only) (
30 secs
) – activates when the power unit is placed at an angle that could affect
the canister full indication. The power unit will continue to run whilst this message is displayed. Return the power unit
to an upright position.
LOW BATTERY
(Fig. 11) (only appears during battery operation) – battery icon at the top left of the normal
operation display screen flashes on/off, indicating battery charge is low and battery needs recharging. Plug into a
power source to charge.
FATAL ERROR
(Fig. 12) – the screen displays a letter E followed by a number, indicating an irrepairable fault. This
screen should never appear during normal operation but if it does, please contact Direct Healthcare Group.
* the sounder can be silenced temporarily by briefly pressing the UP/DOWN button.
