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 backdraft 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)
- Switch on appliance and all air conditioning (fan, dryer) with maximum power
- Start measurement
- Follow instructions on display: alternately open and close windows/door
After switching on the DP5 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.
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.
In addition, the fuel throughput can be entered for fireplaces with solid fuels (for example:
Stoves - how many Kilograms of wood per hour). The air requirement is calculated from this.
Before measurement, the rated power of the system must be entered and when the
Temperature is below 0°C.
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.

Detailed 4/8 Pa-Measurements should be carried out with a power supply unit or the device
should be charged to at least 80%. When the battery is charged 100% it will be able to handle 2-3
measurements, depending on the amount of air movement.
When the power supply unit or the charger are connected, the Leakage Tester is still mainly
working in battery mode.When the battery, during a measurement, reaches a certain battery
voltage the device will automatically switch to main operation. The battery will then not be
charged!
The battery is only charged when the device is switched off. To do this, the battery/the charger
must have been disconnected from the device for at least 30 seconds.
A full battery charge takes approximately 3 hours.
Important: before each measurement, make sure that the battery has enough voltage. While
a measurement is in progress, the charger cannot be connected to the device. The
measurement would have to be repeated.
