INSTALLING THE CHANNELLING
The channels for exhaust air and incoming air should be installed, if possible, in a warm space below the vapour
barrier to suspended ceilings or casing. The vapour barrier remains intact and the channels do not need heat
insulation. This also ensures that the airflow in the channels will not freeze due to poor heat insulation as well as there
will be no condensing.
Cleansing of channels also becomes easier. The outside air and exhaust air channels are isolated under warm
conditions, see the instructions.
The channels are compiled of type-approved, rubber gasket parts and winded joint channel. Disconnections will be
removed for sealing and noise reasons. Connections will be secured with closing drawstrings and channels attached
securely to the framework with mounting strings so it will persist also cleaning.
Measuring- and regulation equipment of airflow are installed to exhaust channels after noise deductors and inflow
channels before the deductors. For cleansing, a cleansing hatch should be installed.
Remember, that a good functioning channel is: measured correctly, hermetic, carefully attached, properly isolated and
with hermetic inlets!
T
HE S
YSTEM IS AS GOOD AS ITS W
EAKEST PART!
CHANNEL INSULATION
Since the channels are mounted to the upper base, it must be
carefully isolated so that:
humidity will not condensate on pipe surfaces, the air will not freeze
before heat has been stored, the heated incoming air will not freeze
before it is blown into interior.
The two main rules of channel isolation are:
The warm air channels are always isolated in outer conditions with at
least 10 cm of mineral wool and windscreen plating. The cold air
channels are always isolated in inside premises with 10 cm of mineral
wool and steam barrier plating, for instance AE
-chase or AIM-mat.

CHANNELS OF OUTSIDE AND EXHAUST AIR
The outside air will be obtained through grate without an insect net.
The air inlet will be situated to as clean space as possible, far from the
refuse discharge, smokestack, ventilation outlet and exhaust air tube.
The air inlet will be located to a height of at least 2 meters from ground
on the northern side of the building, opposite side to the traffic. Due to
warm summer weather, the outlet channel has to be thermally isolated
in a loft space. Outgoing exhaust air will be channelled above the
rooftop through well-isolated channel and by 700-900mm high isolated
roof duct. (Figure 5).
Fireplaces like hearths, ovens and sauna heating systems must
have a separate isolated combustion air channels with slide cop
ing.

INSTALLATION OF VENTS
Income and outlet vents are installed according to the plan.
Special attention is needed while installing income vents since a
wrong
vent in a wrong place and wrong mounting will affect the air
draught and reduce satisfaction. Steam barriers are well tightened.
In saunas, the income air is channelled above the sauna stove and
outlet will be taken from underneath the sauna platform. The sauna
fans are manually adjustable.
In kitchens, the outlet appliance should be the stove hood with
adjustment plate of three positions and an airflow gauge. The exhaust
vent is operated by the means of the adjuster. The kitchen exhaust
will be attached to the air exchange unit.
In case sound isolation is needed between the separate rooms,
cushioned air transfer vents are used, figure 6. Air transfer routes in
doorways and under the doors will greatly reduce the privacy.

TALTERI DIVK-290 INSTALLATION
The air exchange unit is meant f or warm inner f acilities. Suitable installation spots are,
among others, of fice, dressing or household facilities and technical or warm storages. In case
the temperature of the installation location is lower than room temp
erature, the factory settings
of the appliance must be changed to obtain f aultless f unctioning. The unit can not be installed
into cold outer premises or garages. Exhaust of condensing water proceeds through a water-sealed
joint hose into a washing basin or “dry” floor well. Check the horizontal position of the unit and free flow of
the condensing water.
UPPER BASE DUCT
The channelling is usually mounted to the upper base thermal insulation.
The steam barrier must be hermetically taped.

MOUNTING OF TALTERI
The machine can be raised on top of a boiler or a cabinet. A flexible mat
installed under the machine acts as sound insulation. The condensate hose and
the electrical connections must be installed at the same time.
Another way is to mount the machine to the ceiling
: with four M8 threaded
rods the machine can be mounted through its ceiling mounting plate using
rubber dampers. When using a steam barrier assembled on the roof
trusses, the machine can be suspended from it with four M8 threaded rods
using rubber dampers.
The third way is to mount the machine on the wall with a wall mounting
bracket. After installing the wall mounting bracket, the machine is lifted
onto the bracket, the horizontal plane of the machine is checked and
adjusted. If necessary, the lower part of the machine can be secured. After
removing the locking screw, the bottom metal sheet of the machine is
released by first bending the sheet off one and then the other guide.

DIVK heat exchanger
units have a water trap
built from a condensate hose located under
the base plate (Fig 1). If a condensate trap
outside the machine is used, the machine's
own water trap must be removed and care
must be taken to ensure that the condensate
hose is downsloping.
If the water hose is connected to a 32 mm
sewer pipe located inside the wall, the
connection must be sealed to prevent any
water vapor
entering to the electrical
connection space located under the
machine.
In this case, the supply of intake air
must be ensured by a separate branch made
in the pipe (Fig 2).
If the water hose is connected to the sink
drainage ring, a water trap must be made
next to the sink water trap (Fig 3).
It is not recommended to lead the
condensate hose to a water trap or floor
drain where hot wash or shower water is led.
After installation, check the drainage of water
from the condensate tank.

THE INTRODUCTION OF A VENTILATION UNIT
BEFORE OPERATING YOUR AIR EXCHANGE SYSTEM,
MAKE SURE THAT:
- There are no loose objects within the unit or the air impeller;
- The coverings of construction-time are removed from
the outlet- and exhaust air holes;
- All isolations and steam barriers are in order;
- The heat transfer and fans are in their places;
- The condensing water outlet is installed and the water
is drained out;
- The air impellers and their adjusters are in working order;
- Afterheating is regulated and working.
USAGE DURING INSTALLING
The air exchange unit should be started as soon as
installation permits.
Efficient air exchange promotes drying of the constructions
and prevents damage.
In case channelling has not been completed, fans and adjustments
are missing,filter paper must be used in place of fans to keep
the channels clean andprovide sufficient counterpressure for
preventing overload. The unit must be used with full power and
check the drainage of the condensing water.
The appliance, filters and heat exchangers must be cleaned
and the systemadjusted after the construction works are
completed.
BASIC ADJUSTMENT OF AIRFLOW
The unit alone can not produce good interior ear in case
the channels and fans are installed carelessly and main
adjustments are not made.
Regulate the inlet and outlet fans to the planned positions
and start the unit
at design power speed. Measure the airflow in outside- and
exhaust air channels.
The outlet must be 5-10 % higher than inlet. Check the
pressure level of thechannels by checking from the fans and
adjust it accordingly to obtain the pressure level of 20-30 Pa
for fans; adjust and lock the pattern.Draw measuring- and
adjustment records!
USAGE AND CORRECT LEVEL OF AIR EXCHANGE
The air exchange level is regulated by changing the
working speed of the air impeller from the operating panel.
Airflow of different adjustable positions can be seen
from table 2.
Adjustable position 1 is for basic air exchange for an empty house.
Adjustable position 2 and 3 are normal working positions.
Adjustable position 4 and 5 are efficiency positions (i.e. for saunas).
The selection of the speed is performed from the control panel maintenance
menu. The fans can be adjusted for five different speed settings between
20-100%
The correct usage positions will be found by experience;
observing the purity of the air or sultriness when coming in
from outside, observing moisture on the windows or drying
of the sauna.
AFTERHEATING AND SUMMER BYPASS OF INLET AIR
The unit is equipped with 1000 W electrical battery operated
by the means of triac-adjuster operated by the operating device
for afterheating the heat recovered inlet air.
The temperature of inlet air is usually regulated to +16C.
The temperature may be adjusted to higher during winter so there
would be no draught like feeling. In case of severe frost and
efficiency mode the heating power might turn out insufficient –
in such circumstances, the air exchange should be reduced.
The overheating protection launched during malfunctioning
must be annulled manually.
For the summer time, heat exchanger cell is closed by the bypass
plate, so that the extract air does not heat the outside air.
CONDENSING WATER AND FREEZING PREVENTION
THE SUMMER BYPASS OF THE HEAT RECOVERY UNIT MUST BE IN THE WINTER POSITION WHEN THE
AIRFLOWS ARE BEING ADJUSTED.
In freezing weather, water would freeze in the heat exchanger
unless the frost protection reduced the speed of the supply fan
during the defrost cycle. In severe frosts, defrost cycles are
frequent.
Under abnormal conditions (humidity / cold), the heat exchanger may
freeze and the defrost cycles will not have time to defrost it. In this
case, the machine must be stopped, the door opened, if necessary, the
cold air flow must be prevented and let the heat exchanger to defrost.
In the service menu under WASTE AIR COLD menu, the frost
protection setpoint can be changed 0-10oc. The default setting is 5 oc,
if freezing occurs, the setpoint is increased. In dry conditions, the
setpoint can be decreased.
Check the condensate drain from the machine.
Exhaust air heat exchanger cools the moisture exchanger
condenses into water, Which flows the condensation water in the
pool and from there through a hose through a water trap open sewer.

1. Operating panel
The operation is directed according to settings inserted by the user or installer/manufacturer th
rough the operating panel
as well as according to temperature sensors and set periods.
The operating panel returns from processing state to basic state 2 minutes
after the last button pressing. The return time
from normal position is 2 minutes.
Maintenance menu – for setting suitable parameters for the installation. Maintenance menu is hidden from the end-
user.
“Restoring factory settings” option is also present in the maintenance menu that can be used for turning all settings to
default settings.
The user can use four different selections on the operating panel: weekday and time with the shortcut icons, blowing
speeds, temperatures and air quality values in case there are sensors for these functions.
2. Operating card
The controller card controls the operation of the device user's choices and measurement data from the sensors Received
by. The controller card is
in addition to two transmitter inputs Which can be connected% RH or CO2
transmitter. The card has an additional 4 pcs
switch data inputs and two
EC - a five-speed fan outputs. The control panel is connected to the controller card, a modular six-pole.
3. Controlling of the air impellers
3.1. Speed controlling in default state
The supply and exhaust air controlled 5 speed. Maintenance menu can be selected fans (20-100%) are suitable for
speeds of the subject. The fan speeds are individually user selectable. At speeds in the service menu is the default
setting which the machine starts.
3.2. Overpressurization
Overpressurization state selectable from the outer switch or operation panel. Outlet impeller runs at basic speed, inlet
impeller is set to value of the maintenance menu. The intensifications have no impact at this point. The duration of
overpressurization in minutes is selectable by the user. New push from the switch launches overpressurization from the
beginning. Overpressurization can be shut down also from operating panel. Anti-freeze is deactivated when
overpressurization is switched on.
3.3. Intensification
Intensification of air exchange can be activated from the operating panel or stove hood. Activation from the panel sets
the durability of intensification in minutes (5...120min). Maintenance menu is used to set the quantity and default time.
In this case, CO2/%RH intensification has no impact. Intensification is activated also according to external data.
3.4. CO2- and %RH- intensification
CO2 – transmitter or data given by the transmitter is the basis for air exchange intensification in regulating intervals.
The CO2 maximum limits are set from the panel by the user (250…1500ppm, 50ppm steps). CO2
measuring values can
be seen on the operating panel. The air exchange is periodically intensificated by data of %RH – transmitter or
transmitters. The maximum limits of relative humidity are set from the panel by the user (30…80%, 1% steps). %RH
measuring values can be seen on the operating panel. The card has two transmitter inputs that can be chosen separately
for CO2 or %RH activation and deactivation. Regulation interval is a parameter set through the maintenance menu that
determines how often the impeller speed can change in intensification mode. Set value 5…20 minutes by 1
minute. The
regulation interval is same for both CO2- and % RH intensification.
3.5. Out-of-house function
The “out-of-house” function can be selected from the external switch or from the operating panel. The impellers are set
on minimum speed. However, pr
eviously set intensification or overpressurization will be completed before the impeller
speed is reduced or stopped altogether.
3.6. Weekly clock
The program selectable by the user enables to reduce/increase air exchange during selected periods of time. 5 different
time periods can be programmed at the same time. Each time period can be set with one or several weekdays.
OPERATIONAL DESCRIPTION

3.7. Office mode
The installer can select the office mode from the maintenance menu – this is useful in case the air exchange system is installed
into an office where activities take place mostly during daytime. The speeds are controlled by the weekly clock.
The mode is equipped with continuation switch that enables persons who remain in the office for longer to prolong the
functioning of the appliance by set interval. Intensification and out-of-house mode functions are not usable in the office mode.
Remote control mode can also be selected from the maintenance menu that enables to switch the unit on and off by the mean of
pre-programmed data and weekly clock functions are deactivated.
4. Setting the temperature
Temperature is measured from four different sources: temperature outside, inlet temperature, outlet temperature and exhaust air
temperature. The temperatures are displayed on the operating panel. The precision of measurement is +/- 1 degree.
4.1. Afterheating
The thermostat leads the afterheater located in the inlet channel. The heater can be electrical or water heater and is selected by
the installer from the maintenance menu. The heater keeps inlet air at the exact temperature selected by the user. The desired
temperature can be set from the operating panel. Set values are between 5 – 30 degrees.
4.2. Preheating
Preheater is an electric heater located in the outlet channel. The preheater´s thermostat is driven based on the temperature of
exhaust air. Preheating is meant for prevent freezing of the recovered heat. The temperature setting of the thermostat can be
selected by the installer from the maintenance menu with limitations of 0 – 10 degrees.
4.3. Summer cassette function
The unit is equipped with summer cassette for heat exchange during summertime. The user can select the function manually or
let the functioning be determined automatically according to the temperature outside. During the Summer-
mode, the bypass plate
of the cassette is activated.
The automatic functioning can be set with external temperature between 15 – 20 degrees.
5. Alarms and reminders
5.1. Activation of overheat protection
Information on activation of overheats protection connected to electrical afterheater and preheater is received from the heater. In
case the protection launches, the impellers are automatically set on minimum speed, red indicator light blinks on the operating
panel and the display informs about malfunctioning.
5.2. Inlet air too cold
Inlet air minimum temperature must be set from the maintenance menu. When the air temperature is lower than set, the
information will be displayed on operating panel and red indication light is turned on. The inlet impeller is stopped and the
speed
of outlet impeller is reduced to minimum. These actions prevent the water-circulation battery from freezing.
5.3. Income air too hot
Maximum limit of income air temperature must be set from the maintenance menu. When the air temperature exceeds the set
limits, respective information will be displayed on operating panel and red indication light is turned on. The inlet impeller is
stopped and the speed of outlet impeller decreased to minimum.
5.4. Exhaust air too cold
The exhaust air temperature minimum limits must be set from the maintenance menu (-10 … 10 degrees). When the air
temperature is lower, warning is displayed on the operating panel and red indication light is turned on. The temperature is
attempted to keep above the set value by reducing the speed of inlet air impeller (see also preheating) by regulating it one-step at
a time. In case the air temperature does not rise over the alarm limit even when the impeller is completely stopped, the red
indication light starts to blink and freezing alert is displayed. In case the temperature is restored to normal, normal functioning
will be also restored by increasing the impeller speed one-step at a time.
5.5. Danger of water battery freezing
In VKL machines can be set the temperature of the water radiator from the service menu “radiator return min temp”
and when the value falls down, a notification is displayed and the red ind
icator lights up in the control panel. The inlet
fan is stopped.
5.6. Alarms for remote monitoring
General alerts may be taken into the remote control from potentially free relay. Alarms are obtained inlet air hot or
cold, danger of water battery freezing, overheat protectors and if the machine is stopped.
5.7. Maintenance interval reminder
When the maintenance interval is complete, the respective information is displayed on the operating panel and the indication
light blinks green. The user can reset the reminder after the filters have been changed. The maintenance interval counter is reset
and the new alert will be transmitted after the period has been completed again. The maintenance interval can be set between 3 –
12 months.
5.8. Filter-dirty notice
Differential pressure switch can be installed to the equipment that measures dirtiness of the inlet air filter by monitoring its
differential pressure. When the switch runs, the display transmits the necessity of filter-change and the indication light blinks
yellow. Differential pressure switch is taken into use through the maintenance menu and it deactivates maintenance interval
reminder

MAINTENANCE OF TALTERI
For producing good indoor climate continuously, the air exchange systems require regular maintenance.
The metallic grease filter of stove hood must always be kept clean for fire safety reasons. Cleansing with hot
water dishwasher once a month is
necessary. Substances suitable for machine washing may darken the
aluminium parts of the filter.
The inlet and outlet filters of Talteri must be cleansed at least twice a year.
In summertime the summer cassette plate will be set to summer mode
when the external air should come in fresh and clean.
The heat recovery cell will be pulled out of the unit and washed thoroughly in autumn just before the heating
season begins –the heat recovery will then be at its best. Check the condition of sealing and push the heat
recovery cell back to its place.
The inner painted walls of the unit are easy to clean. Check the condition of sealing, clean the outlet hose of
condensing water and make sure the water flows freely and without any obstructions.
The impellers, air exchange adjusters and thermostats are components that do not require regular
maintenance.
Electrical works can be carried out only by a qualified electrician.
Exhaust air heat exchanger cools the moisture exchanger condenses
into water, which flows the condensation water in the pool and from
there through a hose through a water trap open sewer.
Under abnormal conditions (humidity / cold), the heat exchanger may freeze and the defrost cycles will not
have time to defrost it. In this
case, the machine must be stopped, the door opened, if necessary, the cold air
flow must be prevented and let the heat exchanger to defrost.
In the service menu under WASTE AIR COLD menu, the frost protection setpoint can be changed 0-10
o
c.
The default setting is 5
o
C, if freezing occurs, the setpoint is increased. In dry conditions, the setpoint can be
decreased.
Check the drainage of condensing water!
In case the water-lock dries out and makes pulping noise, you can pour into it a drop or two of cooking oil.
In really cold weather, the head recovery unit heats the preheated inlet air with afterheating. The functionality
can be proved by comparing the temperature of inlet air to the set value of the inlet air afterheating.
The overheat protection has been activated in case the temperature has risen +90
o
C (for instance, in case
of power failure). Reset the overheat temperature by pressing the switch under the threaded contact
protection.
The channels must be checked if the impeller works but the air exchange is inadequate or the temperature
changes in the channels between the interior and the machine. Temperature changes and humidity
concentration in channels must be prevented by improving the i
nsulation
