ELECTRICAL DATA, CONTROL EQUIPMENT
TERMO ICE – AUTOMATIC DEFROSTING
The Termo Ice function ensures an optimal annual efficiency and a
better indoor climate. The unit uses temperature sensors to detect if
there is frost forming in the heat exchanger and starts defrosting on
demand.
When Termo ice is activated the by-pass damper opens and the
outdoor air is directed directly to the post heater by-passing the heat
exchanger. The supply air fan stays in operation during defrosting. The
warm extract air defrosts the heat exchanger.
COOLING RECOVERY
During summertime, if the extract air is cooler than the outdoor air, the
by-pass damper will close. The heat exchanger then recovers cooling
from the extract air. This primarily applies if there is some form of
cooling device in the house. When the extract air is warmer than the
outdoor air the by-pass damper will again be opened.
HUMIDITY
Optional humidity sensor for extract air. The unit can be controlled to
maintain the humidity below certain level via the Plus Touch panel.
CO2
Optional carbon dioxide sensor for extract air. The unit can be control-
led to maintain the carbon dioxide level below a certain level via the
Plus Touch panel.
MODBUS RTU
The unit has a Modbus RTU interface as standard. The unit can be con-
trolled via the Modbus in terface.
ALARMS
The unit has built-in alarms for filter change and sensor errors.
SEC CLASS
SEC class A+ is fulfilled in a cold climate zone
(Nordic countries). Units configured for demand
control CO
2
will achieve SEC class A in an average
climate zone (Central Europe). ECO design directive 1254/2014.
CONTROL EQUIPMENT
The unit is equipped with an electronic control system, Plus control-
ler. The Plus controller handles fan speeds, the by-pass damper and
electrical post heater. The air handling unit is supplied with a 1.25 me-
ter cable and a plug in connector for the main supply. Control connec-
tions are made in the connection box outside the unit. The connection
box has connectors for Modbus connections, cooker hoods, Mosaik
switch and Plus Touch control panel. Any additional sensors are con-
nected directly to the PCB in the control box.
FAN CONTROL
Depending on the controller used, up to four operating modes can be
selected (see accessories):
AWAY is used when nobody is at home for a longer period e.g. vaca-
tion.
NORMAL is used for normal ventilation air flow.
BOOST is used when there is a need for a higher ventilation air flow (it
will automatically revert after 60 minutes).
MAXIMUM generates full fan speed.
The fan speeds can be adjusted independently of each other on every
operating mode.
TEMPERATURE CONTROL
The Plus controller controls the by-pass damper and the electrical post
heater to maintain the supply air temperature at set point. The electri-
cal post heater is activated when the energy recovery from the heat
exchanger is insufficient.

MOSAIK CONTROL
Mosaik is standard light switch sized controller with three operating
modes. The right switch controls whether the unit is in away mode or
normal operation and the left switch controls home or boost operating
mode when right switch is in normal mode.
COOKER HOOD CONTROL
The air handling unit’s operating modes can be controlled with a coo-
ker hood. Compatible Iloxair cooker hoods can also indicate and reset
the unit’s alarms. For more detailed information please read the cooker
hood manual. Using Iloxair cooker hoods is strongly recommended for
ensuring the compability.

PLUS TOUCH PANEL
With the Plus Touch panel it is possible to change for example fan
speeds, temperature set point, date and time.
TEMPERATURE SET POINT
It is possible to change the temperature set point and to read the tem-
perature of the different temperature sensors via the Plus Touch panel.
The temperature sensors are located inside the unit. This means that
they do not precisely reflect the actual outdoor or indoor air tempera-
tures.
WEEKLY SCHEDULES
The unit can be set to operate according to user-defined weekly sche-
dules. A setup wizard guides you through the basic set-up. It is pos-
sible to edit the schedule for each day afterwards.
ALARMS
The Plus Touch panel shows alarms for example filter change and
sensor errors. For more information regarding alarms see separate
parts in this document.
FAN OPERATING MODES
All four operating modes can be selected via the Plus Touch panel:
Away is used when nobody is at home for a longer period e.g.
vacation.
Home is used for normal ventilation air flow.
Boost, there are several variants:
• Boost is used when there is a need for a higher ventilation air flow.
• Boost 60 minutes sets the unit into BOOST mode for 60 minutes.
• Fireplace timer 15 minutes is used when the user wants to light a fire.
Maximum generates full fan speed.
Note! If a separate Away/Normal control switch is used, the switch
must be in the normal position to allow changes via the touch panel.

ADDITIONAL CONTROL EQUIPMENT
HOME/AWAY SWITCH
The Home/Away switch allows you to reduce
the ventilation rate. To enable control from an
Plus touch panel or other additional control
equipment connected to the unit, the switch
must be in the Home position.
FIREPLACE OR BOOST SWITCH
The switch may be used either as a fireplace
switch or a regular boost switch. When used as
a fireplace switch it changes the pressure con-
ditions in order to make it easier to light a fire.
When in use, the fireplace switch overrides any
other switches.
CO2 SWITCH
The CO
2
switch measures the carbon dioxide
level in the room and boosts ventilation if the
set point level is exceeded. When the CO
2
level
drops below the set point the fans return to their
previous speed.
HUMIDITY SWITCH
The humidity switch boosts ventilation when
the relative humidity in the room exceeds the
set point. During the cold season, the set point
should be set to approximately 50%. During the
warm season, the set point should be higher,
approximately 70%. If the set point is correct
then the humidity switch boosts the ventilation
when using the shower or sauna. The normal ventilation rate is resu-
med after approximately 1–2 hours. During certain conditions the humi-
dity level may be so high that unit will stay in boost mode. In order to
prevent this raise the humidity set point.
3-SPEED OR 4-SPEED SWITCH
Easy to use switch for choosing between
three or four different operating modes.
TEMPERATURE CONTROL, ELECTRICAL HEATER
Temperature set point.
The supply air temperature set point is adjustable via the knob on the
front edge of the electrical box inside the unit. The temperature set
point can be adjusted between 12 and 26°C, recommended set points
being between 17°C and 20°C. It is also possible to set the tempe-
rature set point via the Plus touch panel (accessory). The electrical
post heater will not be activated unless the outdoor air temperature is
below the post heater activation temperature default being 8°C. Please
note that the temperature set point is not be mistaken to be the gene-
ral indoor temperature. The general indoor temperature is to be hand-
led by the heating system.
TEMPERATURE CONTROL
During cold periods the by-pass damper closes and the cold outdoor
air is led through the counter flow heat exchanger (winter mode). The
supply air will then be heated from the warm extract air. If the outdoor
air is cold and the heat energy recovered from the extract air is not
enough to achieve the supply air temperature set point the post heater
will activate in order to maintain the supply air temperature. During
warm periods when the heat recovery from the extract air is not
needed the by-pass damper opens and the outdoor air is led past the
heat exchanger directly into the supply air fan (summer mode).

MAINTENANCE
GENERAL
Filters, fans and the counter flow heat exchanger are very important
for the function and economy of the unit. It is therefore important that
these are kept clean and in good condition. We recommend a general
check of these parts during filter replacement, every 6 months. For sa-
fety reasons, general caution should be observed during maintenance
of the unit. It is recommended to use protective gloves.
FILTER ALARM AND REPLACEMENT OF FILTERS
The filters for the extract and supply air should normally be replaced
twice a year. In areas where there is a lot of airborne particles such as
in cities it may be necessary to change the filters more often. The Plus
controller is set to remind the user to change the filter every 6 months.
It is possible to change the interval when using Plus touch panel.
Follow the instructions below to change the filters:
1. Open the hatch door.
2. Disconnect the power by using the power switch on the electrical
box.
3. Remove the used supply air filters (ISO Coarse pre-filter and ISO
ePM1 55% filter) from the console.
4. Remove the used extract air ISO Coarse filter.
5. Insert the new supply air filters (ISO Coarse pre-filter and ISO ePM1
55% filter) and extract air filter (ISO Coarse filter).
6. Turn on the power switch and close the hatch door.
7. (If equipped with accessory Plus Touch panel, reset the filter alarm.)
Warning! When replacing dirty filters, use of a face mask is
recommended (lowest class, FFP2).
!
Note! Only use filters recommended by FläktGroup at exchange. If
incorrectly selected filters are installed, there is a risk that perfor-
mance and air quality will not be achieved. FläktGroup disclaims
warranty liability if incorrect filters are installed upon replacement.
CLEANING THE FANS
The fans should be checked every two years. The fans should be
cleaned if there is dirt on the impellers. Note that the fans are not be
cleaned with water or other fluids. The fans are only to be cleaned with
a vacuum cleaner or a brush. It is strongly recommended to let an
educated professional maintenance the fans.
Before cleaning the fans, heat exchanger etc, the unit should always have the power
disconnected.
1. The heat exchanger is removed from the unit
2. Remove the screws for the cover plates of the fans.
3. Disconnect the electrical contacts and remove the fans from the
unit.

OVERHEATING PROTECTION, TEMPERATURE
ALARMS, OTHER ALARMS
POST HEATER ELECTRICAL
The unit has an overheating protection device that switches off the
electrical post heater if the temperature is too high. If the overheating
protection has triggered, the user needs to manually reset this. See
figure below:
Overheating protection
reset button
When the overheating protection has been triggered remove the plastic cover and
press the reset button on the front edge of the electrical box inside the unit.
Note! If the overheating protection device has been triggered it is
important to find the overall cause of the problem.
TEMPERATURE ALARM
The unit automatically identifies temperature sensor errors. In the
event of an error, arrange a service visit.
CONDENSATION, WATER INSIDE THE UNIT
When the unit is running, moisture from the extract air may condensa-
te in the heat exchanger. This applies mainly during autumn and winter.
The amount of moisture condensated from the extract air depends
on moisture production in the house such as cooking and showering.
Typically in newly built houses the construction materials emit their
excess moisture during the first years. In the bottom of the unit there
is a drainage for removal of the condensate. It is important to regularly
check the function of drainage to prevent clogging. After the summer
the water in the water trap may have evaporated. This can result in a
gurgling noise. Remedy this by pouring water into the drain hole inside
the unit to fill the water trap.
The chromed ball-fitted water trap allows for a silent and reliable the disposal of
condensate.
The heat exchanger is cleaned with either a vacuum cleaner or by showering it with
water.
Note! Acetone or a similar solvent must not be used. The heat ex-
changer is not to be soaked in water etc. Do not use sharp objects.
Make sure that the heat exchanger is completely dry before rein-
stalling.
CLEANING THE HEAT EXCHANGER
Check that the surface of the heat exchange is not covered in dust.
Clean by either using a vacuum cleaner, compressed air or by
showering the heat exchanger with water. If this is not sufficient, apply
a grease-dissolving fluid such as dish soap and wash the heat ex-
changer.
4. Detach the impeller from the fan by removing the four screws.
5. Clean the fan and impeller with a brush.
6. Reinstall the cleaned fan in reverse order.
The heat exchanger is pulled out of the unit. When reinstalling make sure that all the
gaskets are in the right possition and fully intact.

Replacing the filters and cleaning the unit: Replace the filters according
to the instructions, vacuum the unit inside and wipe with a damp cloth
if necessary. Clean the water trap at the same time.
Note! Depending on the situation it may be necessary to change
the filters more often than indicated in this manual. In that case, the
other maintenance actions should also be performed at more frequ-
ent intervals.
Checking the operation of the unit: Listen to the fan sounds (do they
both work, is the sound balanced, are there noises that may indicate
bearing faults?). Inspect the condition of the unit visually.
Cleaning the heat exchanger: Clean the heat exchanger according to
the instructions. Perform the inspection every spring and clean if dirty
or every 1–2 years.
Checking/cleaning the fans: Perform the inspection every two years
and clean if dirty or every 4-5 years. The cleaning is strongly recom-
mended to be performed by a professional to ensure that the fans’
balance pads do not become dislodged.
Note! The ventilation ducts should be cleaned by a professional
every 5–7 years or according to the local regulations.

DUCT CONNECTION, INSULATION OF THE DUCTS
Note! During installation, the instructions relating to the unit and
duct insulation must be adhered to without deviation. Otherwise
there is a risk of condensation and moisture resulting in a major
damage.
DUCT CONNECTION
Exhaust air from the unit should only be connected to a ventilation duct
intended for the purpose. Connection should not be made to a chimney
or a smoke or gas duct. If the unit is being used in premises with for
example an open fireplace or heating stove with a chimney or smoke
or gas duct, an adequate supply air flow must be provided. A kitchen
duct must be provided in accordance with applicable regulations.
INSULATION OF DUCTS
In order to the unit working as intended the duct system should be
installed in a professional manner in accordance with local regula-
tions and following the ventilation plans made by a professional. This
includes installation of the ducts through external walls containing
insulation and vapour barriers, external roofs and joists. If this is not
done in professional manner there is a risk for condensation, resulting
in possible damage to the unit, duct system or the structure itself due
to moisture. In the case of replacing older units, it is also necessary
to ensure the quality of the ducts and duct insulation. Supply air ducts
and extract air ducts are filled with warm air. If those ducts are placed
in unheated spaces they must be insulated. The insulation should be
applied externally and have a wind-proof surface layer. Outdoor air
ducts and exhaust air ducts are filled with cold air. If those ducts are
placed inside the building’s vapour barrier they must be insulated and
have a diffusion-proof (moisture-proof) surface layer. Given the high
degree of heat recovery achieved by unit the exhaust air also gets very
cold and must be thermally insulated.It is also important that the wall/
ceiling which the unit will be mounted on is well insulated.

MOUNTING EXAMPLE
Caution! To avoid the risk of moisture damage to the roof
and roof insulation, the outdoor air duct should not be instal-
led horizontally inside the roof insulation. Outdoor air duct
should be insulated with 100 mm mineral wool mat with a
moisture-proof surface layer in cold spaces.
The exhaust air duct from the unit should
preferably run straight to the roof, without any
horizontal runs inside the roof insulation.
The outdoor and exhaust
air duct must be insulated
with 100 mm mineral wool
mat with a moisture-proof
surface layer in cold spaces.
If cooker hood is connected
to the unit, EI30 insulation
should be used.
The condensate pipe must run into a floor drain, not directly into
the sewer. The water seal height of the water trap must be at
least 100 mm. There must be no more than one water trap and
no horizontal runs in the condensate pipe.
NB! If the unit is equipped with
a cooling coil, the supply air
duct must be insulated, e.g.
with Armaflex, or with insulation
covered with an airtight vapour
barrier.
The outdoor and exhaust air ducts must be
insulated with 100 mm mineral wool mat with a
moisture-proof surface layer in warm spaces.
The extract and supply
air ducts do not need any
insulation in warm spaces.
The extract and supply air
ducts must be insulated with
100 mm mineral wool mat
and preferably inside the
loose wool in cold spaces.
Installation example.
SITE OF INSTALLATION
The air handling unit should be installed in a heated space. Ambient
temperature should be above +10 °C. The ILOX 86Plus can be either
wall mounted with the accessory mounting bracket or ceiling mounted
with the accessory ceiling mounting frame.
INSTALLING THE CONDENSATE REMOVAL PIPE
At the bottom of the unit, there is an outlet (1/2“ internal thread) for
condensate removal. Fit a pipe or a rigid hose with an inner diameter
of at least 12 mm between the condensate outlet and a floor drain or
the waste connector of a wash basin. The condensate removal pipe
should not run directly into the sewer. A water trap has to be instal-
led in the condensate removal pipe. Make sure that the condensate
removal pipe is always leaning towards the floor drain or wash basin.
The condensate removal pipe should always be installed in warm con-
ditions. If the condensate removal pipe can not be installed in warm
conditions, a heating cable should be installed in order to prevent fre-
ezing. Make sure to fill up the water trap.

lower edge of the frame.
6. Put the power cord and the external connection box through the lar-
ge opening in the mounting frame.
7. Lift the unit to the ceiling mounting frame so that the mounting
hooks fit to the corresponding slots on top of the unit. Use some
force upward from the bottom of the unit until the unit locks to the
mounting frame with clicking sounds. Double check that the unit is
secured tightly.

ELECTRICAL INSTALLATION
The air handling unit is equipped with a plug connector, which can be
plugged directly into a wall socket that has an earth connector. The
wall socket should be installed inside the building’s moisture barrier
to a place where it can be unplugged with ease. Electrical installation
and connections for the unit must be made by a qualified electrician.
The unit is equipped with a service switch for switching off the power.
When installing accessories or other electrical connections, power
should be switched off by disconnecting the plug from the socket. The
unit is equipped with an external connection box for connecting some
of the basic accessories of the unit.
EXTERNAL CONNECTION BOX
An external connection box is used to make the most common control
connections to the unit. The external connection box is mounted above
the unit or in the ceiling, next to the service hatch. It is strongly re-
commended to install the external connection box inside the building’s
moisture barrier.
INTERNAL CONNECTIONS
The PCB in the unit’s control box is used to make the physical connec-
tions required for external control and to connect any of the following:
internal carbon dioxide transmitter, carbon dioxide switch, internal
humidity transmitter, humidity switch, emergency stop switch, Home/
Away switch and fireplace boost switch.
Note! Extra length must be allowed for the cables, so that the inside
of the electrical box can be pulled out sufficiently for installation.
