Product Manual

• Remove the back-cover and insert 3 AA batteries. Make sure to use high quality batteries to
ensure functionality. Batteries should at least comply to the following specification: AA size,
alkaline, capacity: 2xxx mAh, voltage: 1.5V.
• The device will boot up
automatically
• At first start up, a selection needs to be made in function of the filter grade. By pushing once
(<1s) you can scroll through the different options.
• Select the required setting according to the installed filter grade and press the button for 2
seconds:
• S1 - Setting 1: DD+, PD+, UD+, DDp+, PDp+ – grade – metric, NO (Normally open)
350 mbar, 8000 hours
• S2 - Setting 2: QD+ metric, NO
350 mbar, 2000 hours
• S3 - Setting 3: DD+, PD+, UD+, DDp+, PDp+ – grade – imperial, NO
5.08 psi, 8000 hours
• S4 - Setting 4: QD+ imperial, NO
5.08 psi, 2000 hours
You can ignore the ‘PRE’ menu, as this is for future reset purposes.
• The device is now setup correctly and following menu should appear displaying time in use,
running hours and differential pressure drop.
Checking filter parameters
In order to see the values for time in use, running hours and pressure drop you can scroll through
the following menu by pressing the button once (<1s).
When the device is not in use, it will be switched to stand-by mode. This means the display will
blink every 10 seconds showing the latest parameters. The device is being activated after
pushing the button. The device counters and alarms will be continuously updated and saved
even in stand-by mode.
Warning and service alarms
Warning mode
The LED on the front of the device will be flashing once every 2 seconds in case a warning mode
is triggered. This means that one of the three parameters (pressure drop, time in use and running
hours) is approaching its alarm threshold. Service of the filter and battery change are imminent at
this stage and should be scheduled shortly.
