Mounting, except RHT-out
Select the installation location so that air can flow freely on all sides of the
transmitter, representing the air that is to be measured. Avoid heat sources
and direct sunlight. Mount the device to the measuring location with one
of the following ways:
•
Simply place the DUST40, DUST13, KOMBI-DP or RHT-in on any surface
with the bottom facing down.
•
First mount the separate wall holder with two universal countersunk
screws (ST 2.5 or ST 3.0). Use applicable length and type of screws
depending on wall material. In the correct orientation, the wall holder has
its hooks pointing upwards. Attach the DUST40, DUST13, KOMBI-DP or
RHT-in to the holder.
Mounting RHT-out
This model can be mounted using any of the mounting screw holes in the fixed mounting flanges of the enclosure. Always
make sure to mount the device in vertical orientation so that the ventilation holes in the bottom of the enclosure point
downwards ensuring that water or any other liquids cannot enter through the ventilation holes. Ingress protection class
IP42 can only be attained in the correct vertical mounting orientation.
Mounting KOMBI-DP
Mount as instructed above and then attach the pressure hoses to the two black hose connectors at the bottom of the
device. The device measures the pressure difference between the two hose connector ports. Use only flexible plastic hose
with inner diameter of 4 mm / 0.15 in. When routing and installing the hose, make sure the hose does not get pinched or
blocked. Always minimize the length of the pressure hoses. The maximum recommended pressure hose length is 1 m /
1.09 yd to attain the specified measuring accuracy.
The other hose connector port can and typically will be left without a hose connected to it.
Power supplies
DUST40, DUST13, KOMBI-DP and RHT-in indicates a power-up by blinking the led next to the micro USB socket.
KOMBI-DP, RHT-in, RHT-out variants
These variants are powered with 3 pcs LR6 batteries (AA 1.5 V alkaline). High quality batteries should be used, for example
Energizer EN91.
The device is supplied with batteries already installed, so it is ready to be used.
DUST40, DUST13, KOMBI-DP, RHT-in and RHT-out can alternatively be powered with an external supply. When an external
power supply is used, the batteries can be omitted or used as a backup supply. Use the micro-USB socket to connect an
external supply to the device.
DUST40 and DUST13 variants
These variants with PM sensor must be powered with an external supply. Use the micro-USB socket to connect an external
supply to the device.
