Warning System Check - FACECOVER Tiki Mode D'emploi

Step 4.
Tighten the straps until a comfortable fit is accomplished, making sure there is nothing obscuring the seal around
the face such as hair or glasses that may cause leaks. If the mask does not seal properly and there is a leak, contaminated air
may enter the mask exposing the user to the contaminant. This may also greatly reduce the battery and filter life–putting the
user in danger.
Step 5.
Switch the unit on by holding down the power button for 3 seconds. (Fig 11a, page 3)
The blower unit should temporarily increase in speed until the unit can establish that the pressure inside the mask is positive.
After a few seconds the fan inside the blower unit will slow down as it optimises the airflow to the required amount. The
airflow will now continue to be adjusted automatically according to use e.g. if you start breathing faster the fan will speed up
increasing the airflow so as to keep positive air pressure in the mask at all times. This is to minimise the wear on the filter and
the battery; and for the comfort for the user.
The button marked "Light on/off" is to switch on and off the built in LED work lights (Fig 11b, page 3). Using the light will
reduce the battery time of the blower unit marginally.
Red indicator lights (Fig 11d, page 3)
The left light indicates if the blower unit is on or off. It will always be lit as long as the unit is on.
When only the right light flashes and the blower emits an audible alarm every 5 seconds, the battery power
is low and there is roughly 15 minutes battery power left. Remove yourself from the contaminated area immediately and
charge the blower unit and the external battery back to 100%.
If the two lights to the right start flashing and the blower emits an audible alarm every (one) second; this
indicates that the mask filter is either blocked or there is a major leak causing negative pressure in the mask. This means the
user may be exposed to the external atmosphere. Remove yourself from the contaminated area immediately and charge the
blower unit and the external battery back to 100%.
Step 6.
Attach the battery pack securely onto clothing or helmet. E.g. in your front shirt pocket or onto belt utilising the clip
on the battery pack. We also recommend you secure the cable so that there is no chance it will be caught on anything.

6. Warning System Check

A warning system check must be performed before each and every use.
If a major leak is detected causing a loss of positive pressure in the mask, an audible alarm will sound 2 seconds after the
leak is detected, alerting the user of the leak. Therefore to test that the warning system is functioning, the user need only
manually cause a leak. This can be done by simply pulling the mask away from the face a couple of centimeters (Fig 12, page
3) until the warning alarm sounds. Once this sounds the user can put the mask back on their face; the alarm should stop and
normal operation can proceed.

The warning systems check must be done before each use and only be performed in a non hazardous environment.
