EN
connections are not damaged and heating elements are not bent. They can be damaged or bent due to
uneven heat or uneven and turbulent air direction. Check if electric air heater is clear of unnecessary things
and heating elements are not clogged, because this can cause unpleasant smell or in the worst case – dust
can start burning. Air flow through the air heater should be greater than 1,5 m/s. Heating elements can be
cleaned with hoover or wet textile.
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 changing
filters at least twice per year: before and after heating season or more
Filters are one time used. We do not recommend cleaning them. Stop the air handling unit before changing
filters.
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 20 Picture can be mounted in the air handling unit.
• Close the door after pressure sensor regulating process. Be sure that sensor does not indicate impurity
of clear filters.
• Pressure sensors in the air handling units up to size 900 are regulated and set in factory.
