During inspection, the following operations should be performed:
1. Plate heat exchanger check. Inspection and dedusting of the plate heat exchanger is performed once per year (it
is removed from the unit and blown with an air blast or washed with tepid water).
Plate heat exchanger cleaning. If plate heat exchanger cleaning by compressed air is not effective, it can be
washed with soapsuds (6 Picture), or if needed – use degreasing soak for metal (aluminum) cleaning. Leave
plate heat exchanger to dry in a warm place. It can be mounted only when it is absolutely dry..
2. Fans check (once per year). Polluted fans decrease efficiency.
Fans should be carefully cleaned with textile or soft brush. Do not use water. Do not break balance. Check if
fan freely rotates and is not mechanically damaged, if impeller does not touch suction nozzles, fan does not
spread noise and mounting bolts are screwed.
3. Air heater check. Check if electric air heater is properly fixed, wires 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.
4. 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
Filters are one time used. We do not recommend cleaning them. Stop the air handling unit before changing
filters.
Clogged filters unbalance ventilation system, air handling unit uses more power.
