9 Troubleshooting
Note:
If you cannot find a solution to your problem in this section, speak to Systemair technical support.
Problem
The pump is not running.
No or insufficient cooling or
preheating capacity.
The air output is not sufficient.
There is unusual noise when the
product starts or operates.
Increased condensation.
Cause
Incorrect control unit parameters.
Incorrect pump settings.
The electrical connection is not
correctly done.
System pressure is too low or
incorrect pump settings.
The filter is clogged.
There is blockage in the air inlet or
the duct system.
There is strain in the connections of
the duct system.
Siphon is empty.
Cavitation due to insufficient suction
pressure
Condensate drain is clogged.
Condensation on the pipes and / or
air duct connections.
System is not protected against
frost.
High inside air humidity.
Solution
Make sure control unit settings are
correct.
Make sure the pump settings are
correct.
Do a check of the cables and
connection points, if the electrical
connection is correctly done the
pump is defective.
Speak to Systemair technical
support.
Do a check of the system pressure
and fill the system if necessary.
Do a check and correct the pump
settings.
Change the filter.
Remove the blockage.
Loosen the connections, align the
parts of the duct system correctly
and tighten the connections.
Fill the siphon.
Increase the system pressure within
the permissible range.
Clean the condensate drains (top and
bottom of the geothermal heat
exchanger).
Insulate duct connections and pipes.
Insulate the room where the
geothermal heat exchanger is
installed or move the geothermal
heat exchanger to a frost-protected
room.
Make sure that room where the
geothermal heat exchanger is
installed has good airflow regularly.
If the air humidity remains high,
move the geothermal heat
exchanger to a room with a lower air
humidity or insulate the parts on
which the condensate occurs.
