FANS
The fans are powered by energy-efficient EC motors.
HEATER
A heater (electric or water coil) is supplied as standard.
TEMPERATURE CONTROL
In cold weather the bypass damper closes and outdoor air is routed
through the heat exchanger in order to recover the heat from the ex-
tract air (winter mode). The heat that the counterflow heat exchanger
recovers is generally sufficient.
When outdoor temperatures are low and the desired supply air tem-
perature cannot be achieved using recovered heat alone, the heater
assists.
In warm weather the bypass damper opens and the outdoor air is
routed past the heat exchanger (summer mode).
CONTROL EQUIPMENT
The unit is equipped with an electronic Curo control unit The control
unit is integrated into the unit and controls the
operation of the fans, the bypass damper and the heater.
FAN CONTROL
Three operating modes can be selected via the Curo Touch control
panel:
• “AWAY” (low speed) is only used when the premises are left empty
for an extended period (during a holiday for example)
• “HOME” (normal speed) is used for normal ventilation flow
• “FORCED” (high speed) is used when there is a greater need for ven-
tilation (reverts to normal automatically after 120 minutes)
The speed of the fans can be adjusted independently of each other.
COOLING RECOVERY
In the summer, if the extract air is colder than the outdoor air, the by-
pass damper closes to recover cooling from the colder extract air. This
applies particularly if there is some form of cooling unit in the facility/
house.
DEFROSTING, TERMO ICE
During cold periods when frost forms in the heat exchanger, the Termo
Ice function defrosts the unit and the supply air fan is stopped. Defros-
ting does not start until it is really needed. In other words when much
of the heat exchanger has been covered in frost. This is to allow the
highest degree of heat recovery possible. The Termo Ice system can
detect the difference between frost and condensate.

CLEANING OF THE HEAT EXCHANGER
Check that the heat exchanger fins are not coated with dust. Clean by
vacuuming or using compressed air. Or spray them with water.
Alternatively clean them using a degreasing agent (ordinary washing
up liquid for example) and rinse clean with hot water.
NOTE! Do not soak the heat exchanger! Do not use dishwasher deter-
gents or lye! Do not poke the air ducts with a sharp object. Allow to dry
before reassembly.
MAINTENANCE AND CLEANING OF HEAT EXCHANGER AND FANS
Before cleaning the heat exchanger, fans etc., the unit should always have the power
disconnected. Pull out the plug and then open the door using the handle.
CLEANING OF FANS
Note that the fans must not be cleaned with water or other fluids; they
may only be vacuum cleaned or brushed.
Pull the heat exchanger out of the unit. During reassembly, check that the seals are
positioned correctly.
Vacuum or spray the heat exchanger with water
3. Disconnect the electrical connection and remove the fan from the unit.
4. Disconnect the impeller from the fan housing by removing the four screws on the
side of the fan housing.
5. Clean the impeller housing and the fan blades with a brush.
6. Reinstall the fan.
GENERAL
The fans, filters and heat exchanger are very important for the opera-
tion and economy of the unit. For this reason, it is crucial for them to be
kept clean and in good condition.
We recommend a general check-up every 6 months. For safety rea-
sons, general caution should be observed during maintenance of the
unit. If necessary, use protective gloves.
2. Unscrew the screws on the cover panels above the fans.
CONDENSATION, WATER IN THE UNIT
When the unit is running moisture condenses from the extract air. This
is greater during autumn and winter. The amount of moisture in the
extract air depends on various factors, during food preparation and
showering for example. A new house gives off a lot of moisture for the
first few years.
In the bottom of the unit is a drain hole for condensate drainage. Check
that the drain hole is not blocked at regular intervals.
At the end of the summer the water in the water trap may have evapo-
rated. This can result in a gurgling noise. Remedy this by pouring water
into the drain hole to fill the water trap.
1. Pull the heat exchanger out of the unit.

THERMAL OVERLOAD PROTECTION, TEMPERATURE ALARM, OTHER ALARMS
RESETTING THE THERMAL OVERLOAD PROTECTION
The fan motors are equipped with thermal overload protection that is
reset manually by temporarily disconnecting the power.
The electric heaters have dual thermal overload protection devices,
one that resets automatically and one manually. The automatic thermal
overload protection device trips before the manual one.
If the manually reset thermal overload protection device has tripped the
power must be disconnected.
Let the electric heater cool for a few minutes before unscrewing the
plastic cover over the reset button. Reset the thermal overload protec-
tion device by pressing the reset button.
If the manually reset thermal overload protection device trips again, call
out service personnel.
TEMPERATURE ALARM
The temperature alarm stops the unit if the supply air temperature
drops below +5 °C. The alarm is blocked during defrosting or during for-
ced operation via the cooker hood. A 10-minute delay ensures that the
supply air temperature has time to rise if operation has been stopped.
OTHER ALARMS
The unit has a number of other alarms. These are displayed in plain
text on the Curo Touch control panel.
EXTERNAL ALARM
An external alarm can be connected to the unit. If this alarm is trigge-
red, the unit will stop running

UNIT WITH A WATER COIL, FROST PROTECTION
Temperature range for the water coil temperature control.
UNIT WITH A WATER COIL
On units with a water coil the supply air temperature is adjusted using
the thermostat valve in the unit, see the figure below.
The table under the figure shows the temperature corresponding to the
set value. We recommend settings 3 or 4 in heating mode.
In summer we recommend *.
FROST PROTECTION
* = 8 °C (summer)
1 = 11 °C
2 = 14°C
3 = 17°C
4 = 20°C
5 = 23°C
6 = 26°C
The frost monitor is used to prevent frost damage to the water coil
when outdoor temperatures are low. The frost protection sensor on the
water coil return line generates an A alarm that stops the unit when the
water temperature drops below 10 °C. Investigate why frost protection
tripped and then reset the alarm.

DUCT CONNECTION
Exhaust air from the unit may only be connected to a ventilation duct
intended for this purpose. Connection must not be made to a smoke or
gas flue. In case of extract air ventilation in premises where a smoke
or gas flue is used (for instance, an open fireplace or heating stove),
an adequate supply air flow must be ensured A kitchen flue must be
installed in accordance with applicable regulations.
DUCT CONNECTION, DUCT INSULATION
Note! During installation, the instructions regarding unit installation and duct insulation must be adhered to without deviation.
Otherwise, there is a risk of condensation and moisture resulting in major damage.
DUCT INSULATION
In order for the installation of the unit to be effective, it is crucial that
the installation of the ventilation ducts in the unit, as well as the instal-
lation of ducts through external walls containing insulation and vapour
barriers, roofs and joists, is executed in a professional manner. Other-
wise there is a risk of condensation, resulting in moisture damage.
If older units are replaced, it is also necessary to inspect ducts and
duct insulation for damage and ensure they are of adequate quality.
Supply air ducts (T) and extract air ducts (F), i.e. ducts containing warm
air, which are located in unheated spaces, must be insulated. The insu-
lation should be installed externally and have a windproof surface layer.
Outdoor air ducts (U) and exhaust air ducts (A), i.e. ducts filled with cold
air, which are located inside the building’s vapour barrier, must be in-
sulated and have a diffusion-proof (moisture-proof) surface layer. Given
the high degree of heat recovery achieved by the unit, the exhaust air
also gets very cold and must be thermally insulated. Moreover, ducts
which run alongside each other must have a common vapour barrier.
Ducts between the cooker hood, if fitted, and the unit and exhaust air
duct are to be regarded as kitchen flues. This means that particular
measures must be taken; see the table below.
For the designations of the various ducts, see "Duct definitions" on the
next page.

Wall mounting using wall rails.
Condensation drain with water trap.
LOCATION
Install the heat recovery unit in a warm space. This should preferably
be warmer than +10°C. The Ilox 89 should be installed on a wall using
a wall bracket, or on the ceiling using a ceiling bracket (accessory).
CONDENSATION DRAIN
There is a connection (1/2" internal thread) at the bottom of the unit for
draining condensation.
Use a length of 12 mm pipe or rigid hose to route condensate to the
floor gully or to the wash basin/sink water trap.
Do not connect the condensation pipe to the outflow directly. Always
create a water trap on the pipe by bending it as shown in the adjacent
figure. The height of the water trap is to be 50 - 100 mm. Ensure that
the pipe slopes downwards for its entire length. Fill the water trap.
WALL MOUNTING
1. Screw the wall rails (1) securely into place on the wall. The wall
should preferably be brick, lightweight concrete or concrete. If the
substrate is plasterboard or similar, the wall mounting must be rein-
forced with mesh or plywood.
2. Use a spirit level to check that the rails are horizontally and vertically
true.
3. Remove the two rear mounting bolts, x 2, at the corners of the unit.
4. Lift the unit so that it is resting on the lower edge of the wall rail.
5. Then lift the unit up a little, align the mounting hooks with the holes
on the rear of the unit.

INSTALLING A WATER HEATER
Connecting a water heater
INSTALLING A WATER HEATER
Connect the water coil to the heating system in the home; in parallel
with the radiators for example. Generally, thanks to the unit’s high effi-
ciency, no more heat output is needed than connecting the water coil to
the same branch as the underfloor heating for example.
The inlet is connected to the pipe using a thermostat valve, see the
adjacent figure.
Create an inspection opening if the connections are in a space above
a suspended ceiling. Install a bleed valve at the highest point of the
return line.
When the circuit has been topped up and bled, ensure that the water is
circulating in the coil before commissioning.
The system may need to be bled again after a few days. Ensure that
the air flows are calibrated before the water is connected. There must
be a continuous flow of water in the coil in winter due to the risk of
frost.
