3 Installation
Mount the sensor in the mounting lug at the top of the sensor, filter facing down. The offset from vertical must
be max. 15
o
(see the illustration). DOL 53 must be mounted so that it is accessible in connection with mainte-
nance and must not be subjected to splash water.
Ensure free air passage around the sensor filter. Do not expose it to direct sunlight as this will affect the mea-
surements.
DOL 53 must warm up for half an hour before being ready to measure (see the section of LED indication).
The sensor must be placed in middle of the livestock house or in the center between walls/filters when used in
an air cleaner. Make sure there is an adequate distance to walls and air inlets.
