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 guard" in the control panel (fig. 4).
The bag filter cannot be cleaned and must be changed as necessary. New filters can be ordered from
Systemair. Pressure guards monitor Supply and Extract air filters.
Initial pressure drop is approx. for F7 filters = 80Pa and for F5 filters = 45Pa.
Final pressure drop is approx. 240 Pa
2. Checking the heat exchanger (Once a year), (fig.1).
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 not be taken out of the unit.
Clean the surface of the exchanger using a vacuum cleaner with a brush fitting. Take great care not to
damage the surface. If necessary, compressed air may be used to remove dirt. If the transmission belt
is worn or slack it should be replaced.
3. Checking the fans (once a year), (fig.1).
Even if the required maintenance, such as changing of filters is carried out, dust and grease may
slowly build up inside the fan (pos.6 and 7 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 louvers 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/louvers. Diffusers and louvers are mounted in ceilings/walls in bedroom, living room, wet
rooms, WC etc. Remove diffusers and louvers and wash in hot soapy water as required.
(Diffusers/louvers 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.
