Before each measurement please make sure, that the battery has enough voltage.
Do not plug or unplug the power cord during operation! Changing the voltage
during operation will lead to measurement errors.
The Detailed 4/8 PA-Test can be used as proof of adequacy air supply. The test
measures the differential pressure between the indoor and outdoor air. The
device simulates a chimney and is used as a controlled suction system.
After switching on the DPS device, the measurement can be selected in the main
menu.
Please wait until calibration is completed. Then both capillary tubes must be
connected to the front plate. The negative pressure connection serves as a
reference pressure and should be outside of the building. The positive
pressure connection remains in the installation room. Hoses can be detached by
pressing the blue discs.
- Remove the connecting piece of the fireplace and connect the suction hose with a suitable Sealing Element to the exhaust gas system.
- Open an outside window or a door to the reference room and test proper operation of the appliance. Ensure that there are no backdralt conditions.
- Select 4Pa-Test, device will calibrate
- Lead the hose outside: through a window seal, into the stairways, through the door rebate or the keyhole (+installation room / -outside)

Nl-measurement (optional)
Leakage test
Before starting a Leakage test, the chimney must be sealed with suitable
sealing elements. The hose with the connection plate must be screwed tightly
onto the DPS.
Then plug the capillary hose into the”-” connection.
First pass the capillary hose through the sealing element and then through the tube. Important: the capillary hose must be fixed minimum 5cm behind the hose end. Then insert the sealing element into the stove connection piece or into the fireplace door.
Switch on the DPS. The measurement is started via the menu item “40 pa”.
After entering the dimension, press “Next” to start the measurement. The
device will self-test and then calibrate. The measurement menu will appear.
After the test pressure has been built up, the measurement will start,
duration approximately 1 minute, and finally show the result as an average.
The volume flow is shown with I/min in the display as well the test pressure.
The leakiness is shown in percent. The maximum still permissible leak rate
corresponds to 100%.
Troubleshooting/ Maintenance/ Service
- The flawless functioning of the device must be determined by a regular six-monthly inspection.
- A special calibration Functional test for Leakage Tester must be used.
- It must be avoided that condensate from the exhaust pipe can enter the inside the device!
- The new device must first be charged for approx. 3-4 hours with the mains/charger unit, even if the battery indicator is at 100% when it is switched on for the first time. The full capacity of the battery is only reached after the 3rd or 4th charging process.
Charging processes
- Connect the charger, the red LED lights up continuously. The charging process takes approx. 3 hours. While the battery is charging, the device should not be switched on to see how fully the battery is charged. In this case, the charging electronics may switch off and no further charging will take place. The charging cable must then be disconnected from the device for at least 30 seconds to charge again.
- At the end of the charging process, the flashing pattern changes from continuous light to 2x rapid flashing. When the battery is full, the LED flashes lx and it switches to trickle charging.
- If the device has not been used or charged for a long time, the battery may be deeply discharged. lf this is the case, when the charger is plugged in, it switches to a gentle charge (the LED also flashes twice quickly here). In this case, the charging process takes approx. 24 hours.
- Before each measurement, make sure that the battery has sufficient voltage. The mains/charger unit cannot be connected while a measurement is in progress. The measurement would have to be repeated.
- The battery is only charged when the device is switched off. To do so, the mains/charger unit must have been disconnected from the DPS for at least 30 seconds.
- Detailed 4/8 Pa measurements should be made with mains power or the device is charged to at least 80%. Provided that the above-mentioned points have been complied with.
Sealing bladders:
They must not be pulled over sharp edges, otherwise there is a risk of damage.
Do not inflate the bladder above the specified diameter, otherwise there is a
risk of bursting. A bulge is not a defect or an impairment in functionality.
This can occur due to the material.
Language setting
Go to the “Function Selection” main menu and press the “Setup” button. Press on “Language” to select the desired language.
Notification of fault
