Damper, Operation and Maintenance
Instructions
The function of the dampers is to control, block and
divert the air.
Faulty function gives rise to disturbances that may
result in serious problems. For example, if the outdoor
air damper does not close completely when the unit
stops, the air heating coil is likely to freeze.
If the damper is leaking, this results in increased
energy consumption because of leaks caused by ther-
mal buoyancy forces.
If the exhaust gas damper is leaking, the ventilation
effect is impaired and the air is heated for no benefit.
If the outdoor air damper does not open fully, the air flow
is reduced.
Inspection
1. Check function of the damper actuator.
2. Check the dampers for tightness when they are
closed. If not, adjust the damper actuator to make
the damper tight.
3. Check the sealing strips.
Cleaning
Clean the damper blades with a cloth. If they are severely
fouled, an environmentally friendly degreasing agent can
be used.
Filter types
Pre filter, fine filter and panel filter
Filters in class G4, M5 and M6 consist of deep-folder
filter bags mounted on a metal frame. The filter mate-
rial is synthetic fibre.
Filters in class F7, F8 and F9 consist of deep-folder filter
bags with a metal frame. The filter material is glass fibre.
Panel filter in class G4 (code P4) in synthetic fibre with
waxed cardboard frame (pre-filter).
Carbon filter with pre-filter
The class 7 filter consists of deep-folder filter bags con-
taining active carbon and an integrated class 7 pre-filter.
The filter is suitable for minimising the effect of, for exam-
ple, cooking smells and car exhaust fumes in comfort
systems.
Aluminium filter
The washable knitted aluminium filter is a smooth filter,
25 mm thick, and designed for use in air containing fats.

Filter, Operation and Maintenance
Instructions
The air filters in a ventilation system are designed to pre-
vent dust and other impurities from entering the building.
They should also protect sensitive components inside
the unit, e.g. coils and heat exchangers, from exposure
to impurities.
The dust separation efficiency varies considerably
between various filter types. The dust collecting
efficiency also varies substantially. It is therefore
important to use filters of the same quality and
capacity when you replace them.
Dust separation class is specified with standard des-
ignations:
• Pre filter G4
• Medium filters M5 and M6
• Fine filters F7, F8 and F9
Higher digits denote a higher collecting efficiency. The
filter is designed for one-time use. If the filter becomes
fouled, the unit will lose capacity. The filter should there-
fore be changed if the pressure drop across it exceeds
the specified value.
It is important to stop the unit before changing filters to
prevent dust from coming loose and being drawn into
the unit. The inside surfaces of the filter section should
therefore also be cleaned when the filter is changed.
Inspection
Check the pressure drop across the filter. The pressure
drop is measured with a manometer connected to
measurement outlets. The measurement outlets are
connected to each side of the filter. If the filter has
reached its specified final pressure drop, it must be
changed.
Filter replacement
1. Shut down the unit via the control terminal and
lock the safety switch in the 0 position.
NB: The safety switch is not designed for start-
ing/stopping the unit. Always start and shut
down the unit by means of the control equip-
ment.
2. Wait until the fans have stopped, then open the
inspection door.
WARNING:
Positive pressure inside the unit, risk
of personal injury. Allow the pressure
to drop before you open the inspection
doors.
3. Release the eccentric rails.
Eccentric rails
4. Remove the old filter by pulling it towards you.
5. Clean the filter cabinets.
6. Install the new filter, press in the eccentric rails to
engage them and close the inspection door.
7. If there is a non-removable filter monitor: attach the
probes on each side of the filter.
8. Start the unit.
Cleaning
Vacuum and use a damp cloth to wipe clean the inside
of the filter section.
