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
