In winter, the warm air is extracted from the room (e.g. at a temperature
of 20°Cas in the above diagram) and goes through the ceramic regenerative
exchanger, which absorbs heat and moisture. As a result, the temperature
of the exhaust air drops to e.g. - 7°C. In summer, the situation is opposite -
when the surface of the regenerative exchanger has a temperature higher
than the exhaust air, the regenerator cools down by transferring heat to the
passing exhaust air. After about 70 seconds of exhausting and a few seconds
of pause, the fan automatically switches to the supply mode.
II Supply
In winter, the cold outside air (e.g. with a temperature of -10°Cas shown
in the above diagram) goes through the ceramic regenerative exchanger and
absorbs heat and moisture. As a result, the temperature of the supply air
increases to e.g. 17°C. In summer, the situation is opposite - when the
surface of the regenerative exchanger has a temperature lower than the
outside air (because it has been cooled by the exhaust air ealier), the
regenerator heats up by taking heat from the outside air. After about 70
seconds of supplying and a few seconds of pause, the fan automatically
switches to the exhaust mode.
2.2 PRINCIPLE OF OPERATION (WORKING MODES)
Thanks to the use of the reversible fan, WALLER is a complete supply and
exhaust device, enabling energy recovery from the exhaust air. In the
regenerative mode, the unit works alternately in two cycles:

3. ASSEMBLY
3.1 GENERAL PRINCIPLES
The energy recovery unit should be assembled by a person
experienced in mounting of such devices and - if local law requires it
- with appropriate qualifications.
It is the responsibility of the assembler to make the mounting
according to the guidelines from this instruction and in accordance
with the local regulations in force.
After mounting of the device, the assembler is obliged to fill out the
Warranty Card (positions 1 and 2). It is also treated as a guarantee, that the
assembly was made in accordance with the requirements. The Warranty
Card is included in this manual under the Warranty Terms.
The energy recovery unit WALLER must be mounted in external wall –the
exact assembly description can be found in the section 3.2 of this manual.
The maximal thickness of this partition cannot exceed 420 mm.
The location of the unit should be selected by taking also into account the
local requirements for the location of the air intake and launcher for the
external inlet/outlet. If these requirements are mutually exclusive, reach
out to the supplier.
The unit WALLER must be mounted in the wall with a slope of 3 - 5°
towards to the external inlet/outlet.
WALLER can also work in the ventilation mode,as a supply or exhaust
device only. In such case, the complete mechanical supply and exhaust
ventilation can be provided by e. g. two WALLER devices working
synchronously, where one supplies fresh air to the room and the other
exhausts the used one. However, it should be remembered, that for
devices operating in the ventilation mode, there is no energy recovery.

3–Assemble the external pipe through the wall, so that the external
inlet/outlet is on the outside of the building (3-1). Then turn the external
pipe to place the inlet/outlet facing down (3-2 i 3-3) and pull it from the inner
that the seal fits tightly to the facade (3-4).
4–Fill the gap between the wall and the device with PU foam, fixing the
device to the partition at least in eight places (e.g. according to the bracket's
arms) along the entire thickness of the wall. The application of the foam
inside the wall is facilitated by the plastic tube included in the set.
5–After the foam is dry, insert the inner pipe (including the regenerator, the
prefilters and the regenerator brackets) into the external pipe and align it with
the inner wall surface. The pipe should be additionally sealed with the
additional seal included in the set.
6–If, due to the wall thickness, the inner pipe faced with inner surface
of the wall comes out of the external pipe, the inner pipe must also be fixed
to the partition with foam as shown in step 4.
3.2 ASSEMBLY STEP BY STEP
1–Make a through hole with a diameter of 170 mm in the outer wall.
!

4. INSTALLATION
Before connecting the unit to an electrical installation, it must
be assembled permanently to a suitable partition (according to the
recommendations contained in the section 3).
4.1 CONNECTION TO ELECTRICAL INSTALLATION
The device should just be plugged into an electrical socket type C, Eor F with
the appropriate power supply parameters (see the table in the section 2.4).
5. EXPLOITATION
5.1 EXPLOITATION PRINCIPLES
The user is obliged to be familiar with this instruction before
exploitation of the device.
Before any interference in the device, the electricity supply to the
unit must be absolutely cut off (pull the device’s plug).
Access to the device by parties like unauthorised people, children
and animals is forbidden and should be prevented or at least hindered.
Operation of open device is forbidden (e. g. with separated fan with
housing).
The device cannot work with covered or restricted air inlet
or outlet (e.g. as a result of not keeping the minimum distances
from partitions or obstructed inlet/outlet).
The unit is designed for handling of air at temperature ranging
from -20°Cto 50°C and with relative humidity ≤80%.
If the regenerator becomes frost-covered, it is recommended to switch
the operation mode to the exhaust ventilation one (see the operating
modes in the section 2.2) and only exhaust the air until the regenerator
defrosts again.
In case of any malfunctions in the operation of the energy recovery
unit, immediately cut off the device from the electrical system and
contact directly with the supplier or the distributor.
If the device is not used for a longer time disconnect the unit from
the electrical installation.
The device should be serviced periodically. In order to do that,
cut off the unit from electricity, disassemble the fan with the
housing (by unscrewing it from the mounting plate) and remove the
prefilters and the regenerative exchanger (by removing the internal
regenerator bracket). Then:
clean the fan, its housing and louver from residue with a soft cloth at least
once ayear
wash the prefilters in warm water with detergent at least four times
a year (NOTE! The prefilters must be dried before reassembly)
wash the regenerator in warm water (without detergent) at least
once a year (NOTE! The regenerator must be dried before
reassembly)
The unit must be maintained by a user who is familiar with this
instruction or by an external entity if due to the way of assembly or local
regulations additional authorisations like e. g. working at heights are required.
Before starting any maintenance work, the energy recovery unit must
be disconnected from the power supply.
!
8–Screw the fan together with the housing to the mounting plate using the
attached nut.
!
7–Try and assemble the mounting plate using the included screw and the
mounting pin in a way, that the round flange of the fan is hidden in the
inner pipe and the fan’s housing is faced with the inner wall surface.

!
The frequency of the service should depend on the actual dirtiness -
if the device is operating in an environment with a high concentration
of dust, periodic cleaning should be performed much more often than four
times a year to prevent "clogging" of the energy recovery unit.
After exploitation time, please utilise the unit according to the local
regulations.
6. CONTROLLING
The current operating mode is signalised by the LEDs on the device,
which, depending on the mode:
- glow green if the unit operates in the supply ventilation mode
- glow red if the unit operates in the exhaust ventilation mode
- glow yellow if the unit operates in the regenerative mode
The number of lighting diodes indicates the chosen fan stage (1st, 2nd or 3rd).
