Installation and Operating Instructions
3. Operation
The supply air module draws in room air or fresh air via the filter through
the integral radial fan or fans and delivers this though the heat exchanger
(heating medium LPHW). The heated air is fed into the room using suitable
attachments. The exhaust air module consists of the fan section. The
Airblock FG with attachments can be used for cooling (CPW, direct
evaporator) or as an overpressure system with a particle filter class H13 for
food stores. A bag filter module ISO ePM10 85% (in accordance with
DIN EN 779) can also be fitted.
The components described in these instructions have a connection (electrics,
hydraulics, condensation connection) with the direction of the air flow to
the left.
The installation and maintenance of units with the connection to the right
are carried out in the same way.

Installation and Operating Instructions
5.4 Electrical Wiring
Damage can be caused by the use of incompatible switching devices and
by the use of inadequate protective equipment. The manufacturer does not
accept any warranty in these cases.
Only connect up in systems that have an all-pole trip breaker from the mains
power with a minimum contact opening of 3 mm! Lay electrical cables so
that they are tension-free and not under stress!
All models require a 230 V/ 50/60 Hz power supply and can be controlled
via a combined 0-10V / PWM control input. Models 8 and 9 can be operated
alternatively via an integrated MODBUS RTU interface. A 24 V power supply
is also required for the operation of a flow rate and/or differential pressure
transmitter.
When using residual current circuit breakers for motors with EC technology
these must be sensitive to all types of current (type B). We recommend
a tripping current of 300 mA and time-delayed tripping (super-resistant,
characteristic K) for optimum operating safety.
First connect up the protective conductor „PE“ on the motor terminal box.
Connect the unit according to the applicable wiring diagram as indicated
in the table:
A potential-free 250 V / 6 A (AC1) / 2 A (AC3) changeover contact is
available in the motor terminal box for the switch position 0 or power failure
message. A fan error message is signalled for models 8 and 9 regardless of
the control type.

5.6 Maintenance
5.6.1 Safety Information
Disconnect all parts of the system and secure them against being switched
on again before any wiring and maintenance work!
The housing must only be opened once the motor has come to a standstill.
Risk of injury!
Check the function of all components after completing the work.
5.6.2 Opening the Service Hatches
Stand on a solid surface to carry out maintenance on the Airblock FG, e.g. a
lifting platform. Do not use a ladder! Do not stand within the swivel range
of the hatch!
Caution! Two people are needed to open the service hatch 4! The hatch
weights up to 20 kg depending on the model. Never open the service hatch
further than 90°!
Steps:
1. Rotate the turning bolt (4 or 6 no. per service hatch) 90° inwards using
the square box spanner enclosed.
2. Lower the service hatch until the safety hook automatically hooks into the
lug of the housing connecting strut; the safety hook prevents the service
hatch suddenly flapping downwards.
3. Lift the service hatch slightly; push back the safety hook until it can be
moved past the lug of the housing connecting strut.
4. Carefully lower the service hatch to the desired position.

Installation and Operating Instructions
5.6.3 Housing
The galvanised, double-walled housing 5of the Airblock modules is
maintenance-free. Dirt on the outer housing has no influence on the
operation of the unit. Dirt on the inside of the housing indicates a lack of
maintenance.
5.6.4 Fan Motor
The external rotor motor 6of the Airblock is maintenance-free. The motor‘s
ball bearings, sealed on both sides, are greased for life. In contrast, deposits
on the fan and inlet nozzle reduce the air volume and must be removed:
• Unscrew the turn bolt fasteners and open the service hatch 4. Swivel
the service hatch fully downwards. The fans are now freely accessible for
cleaning purposes.
• Check the fan and inside of the housing at regular intervals (at least once
a year) and clean if dirty.
Please refer to the respective fan operating instructions for more information!
Remove the protection securing the system from being switched on after
completing the work.
5.6.5 Cu/Al Heat Exchanger
The heat exchanger 12 requires no maintenance if the system is properly
maintained, i.e. if the filter is monitored and changed regularly. However,
please proceed as follows if maintenance or repairs are required:
• Carry out a visual inspection of the heat exchanger. To do this, open the
service hatch 4.
• The heat exchanger can be removed through the side service hatch. First
remove the flow and return pipes. Then loosen the screws on the heat
exchanger fastenings and pull out the heat exchanger sideways.
• Observe the safety information in 5.3.
• Residual water may remain in the heat exchanger once it has been
emptied.
Cleaning the heat exchanger:
• Blast the Airblock CU/AL heat exchanger with appropriate compressed
air or flush the heat exchanger with a suitable medium to remove
accumulated dust. Proceed extremely carefully as the aluminium fins
bend very easily and then restrict the air flow! (Bent fins have to be
straightened with an appropriate tool).

5.6.6 Filter Change
Observe the safety information on page 14, sections 5.6.1 and 5.6.2! Filter
cartridge ISO ePM2,5 65% in a Fiberplast frame 11 (with supply air module).
• Check the filter cartridge ISO ePM2,5 65% 11 at least once a year (more
often if necessary). The filter cartridge must be changed if it is dirty.
• Open the service hatch 4and unlock the safety catches. Pull out the filter
cartridge ISO ePM2,5 65% downwards. Use a collection bag if necessary
to avoid dirt and dust dropping down.
• This filter folds in the middle with model 9 units. This makes it easier to
remove and it can be folded to save space with disposal so that very little
dirt can drop out.
• Push the replacement filter cartridge into the filter opening and lock the
filter catches. Replacement filter cartridges ISO ePM2,5 65% are available
as accessories. Filter cartridges ISO ePM2,5 65% cannot be recycled.
• Dispose of the dirty filter. Filter cartridges ISO ePM2,5 65% are metal-free
and fully incinerable.

these must be sensitive to all types of current (type B). We recommend
a tripping current of 300 mA and time-delayed tripping (super-resistant,
characteristic K) for optimum operating safety.
Then connect up the protective conductor „PE“.
Connect the unit according to the applicable wiring diagram as indicated
in the table:
