5. Air damper check (if it is required). Not fully opened outside air damper rises up the pressure in
the system. Water air heater can freeze if outside air damper does not fully close in not working air
handling unit. Mounting and running of air damper should be checked and regulated.
6. Air filter clogging check. Change air filters when air filter clogging is indicated. We recommend to
change filters at least twice per year: before and after heating season, or more 1 .
Filters are one time used. We do not recommend cleaning them. Stop the air handling unit before
changing filters. In the AHU’s were panel filters are used, make sure that filters are tightly inserted in
it’s designated place, when replacing them. Depending on the filter size, in some cases, it is needed
to put additional sealing gasket on the filter frame, to ensure that there is no gaps between filter and
AHU casing.

7. Pressure sensor setting, which indicates impurity of filters.
Pressure sensor is set according to
EN 13779:2007 standard: 100 Pa for small systems, 150 Pa for big systems. Remove cover from the
pressure sensor and turn the cursor due to proper position. The indicator will turn on when filters
will be clogged.
• One of pressure sensors shown in 6 Picture can be mounted in the air handling unit.
• Close the door after pressure sensor regulating process. Be sure that sensor does not indicate im-
purity of clear filters.
