Warning
In order to avoid electrical shock, fire or other damage that might occur in connection with faulty use and
operation of the unit, it is important to consider the following:
•
The system must be installed according to the mounting instructions.
•
Insulate mains supply before service or cleaning of the heat recovery unit.
•
Tumble dryer must not be connected directly to the ventilation system.
•
Make sure the filter is mounted in its place before running the system.
•
Maintenance must be performed according to the instructions.
Maintenance
Maintenance of the Topvex should normally be carried out 3 – 4 times a year. Apart from general cleaning
the following should be observed:
1. Changing Supply / Extract air filter (indicates as “filter to be changed” in the control panel, 1-2
times per year or as necessary) (fig.3)
The bag filter cannot be cleaned and must be changed as necessary. New filters can be ordered from
Systemair. Operation time between filter changes must be re-set after filter change, see page 5

Initial pressure drop is approx. 70 Pa and the final pressure is approx. 220 Pa.
2. Checking the heat exchanger (Once a year), (fig.4)
After long times use dust may build up in the exchanger and block the airflow. It is vital to clean the
exchanger regularly to maintain high efficiency. The heat exchanger can easily be taken out of the unit.
Wash in hot soapy water or use pressure air. Do not use detergent containing ammonia.
Note!
Make sure that the rotor motor is not exposed to moisture.
3. Checking the fans (once a year), (fig.5)
Even if the required maintenance, such as changing of filters is carried out, dust and grease may slowly
build up inside the fan (pos.12 and 13 in fig. 1). This will reduce the efficiency.
The fans may be cleaned with a cloth or a soft brush. Do not use water. White spirit can be used to remove
obstinate settlements. Allow drying properly before remounting.
4. Cleaning extract louvres and inlet diffusers (when necessary)
The system supplies fresh air to the building and extracts the used indoor air via the duct system and
diffusers/louvres. Diffusers and louvres are mounted in ceilings/walls in bedroom, living room, wetrooms,
WC etc. Remove diffusers and louvers and wash in hot soapy water as required. (Diffusers/ louvres must
be put back with their original settings and positions in order not to unbalance the system).
5. Checking the fresh air intake
Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille
at least twice a year, and clean if necessary.
6. Checking the duct system (when necessary)
Dust and grease settlements may build up in the duct system even if filters are changed regularly. This will
reduce the efficiency of the installation. The duct runs should therefore be cleaned/ changed when
necessary. Steel ducts can be cleaned by pulling a brush soaked in hot soapy water, through the duct via
diffuser/ louver openings or special inspection hatches in the duct system (if fitted).
NOTE!
In addition roof cowl must be checked once a year and cleaned as necessary.
