Maintenance
Maintenance of the Topvex TX should normally be carried out 3 – 4 times a year. Apart from general
cleaning the following should be observed:
Changing Supply/Extract air filter
Indicated as “filter to be changed” in the control panel, 1-2 times per year or when necessary
(fig. 2)
The bag filter cannot be cleaned and must be changed when necessary. New filters can be ordered from
Systemair. Operation time between filter changes must be reset after filter change (see page 8,
Filter
alarm
). To change the alarm activating time see page 8,
Filter alarm
.
Initial pressure drop over the filter (Clean filters) is approx. 70 Pa and the final pressure drop is approx.
220 Pa.

Checking the heat exchanger
After a long time of use dust may build up in the exchanger and block the airflow. It is important to clean the
exchanger regularly (once a year) to maintain high efficiency. The heat exchanger can be taken out of the
unit for maintenance
(fig.3)
. Wash in hot soapy water or use pressure air. Do not use detergent containing
ammonia.
Note! The exchanger block is heavy. To take out the plate heat exchanger is normally a job for two
persons.
