TALTERI DIVK-C91 INSTALLATION
WALL ATTACHMENT
The wall mounting kit includes a ceiling mounting plate, a wall-mounting plate
and 15 mm thick insulation pieces.The wall-mounting plate is installed about 25 mm
below the roof surface. The wall attachment plate will be fixed to the wall and
then the unit lifted up to the attachment plate, checked into perfectly horizontal
position and then drill holes for the metal screw through the mounting plate in to
the bottom of the machine. Roof moldings can be put around the machine.
KITCHEN EXHAUST DUCT
The channel output (5) in intended for exhaust channel of the cooker hood.
If the exhaust channel of the cooker hood is not in use, it must close.
If the cooker hood is connected to the kitchen extract duct (past heat recovery),
all the basic ventilation holes of the cooker hood closing damper must be closed
and in the kitchen is needed a separate extract valve which is connected
to the extract air duct.

The air exchange unit is meant fo r warm inner facilities. Suitable installation spots are,
among others, office, dressing or household facilities and technical or warm storages. In case
the temperature of the installation location is lower than ro om temperature, the factory settings
of the appliance must be changed to obtain faultless functioning. The unit can not be installed
into cold outer premises or garages.
UPPER BASE DUCT
The channelling is usually mounted to the upper base thermal insulation.
The steam barrier puncture must be carefully sealed. While installing the unit to
channels, steel steam barrier plate, supplied as extra, will come handy. The steam
barrier plate is attached securely between the roof trusses, 10mm smaller hole
must be cut into the gasket mat and channels are installed through the plate.
The steam barrier must be hermetically taped.
The unit can be attached right to the steam barrier plate with four M8 thread bars
at desired height. Note the measurements of the steam barrier plate during the
installation process.
The bolts and thread bars are purchased separately.
CONDENSATE WATER
Condensate drain is connected to the machine condensate connector (3/8 "external thread).
Condensate can be made at a least 10 mm in the bore copper pipe or Relatively stiff hose.
The water pipe Making about 10 cm in the water trap and the tube is connected to a floor drain.
The water line shouldnt be connected directly to the sewer.

INTRODUCTION OF THE AIR EXCHANGE SYSTEM
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 levels
for vents; 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 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 500 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 +17C.
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.
During summertime, the bypass plate will be opened so the extract air will
not warm up the inlet air.
CONDENSING WATER AND FREEZING PREVENTION
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.
In freezing temperatures the water to Prevent freezing of the exchanger
with double
-acting blocking That first frost the preheater is switched on
and the temperature rises over the set value switched off.
If the preheater resistor power It is not enough, and the exhaust air
temperature drops less than a "waste of cold air" limit-value power
supply fan stepwise dropped until the threshold is reached.

PURE JOY FROM INDOOR AIR !
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
or 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.
During the frosty period the heat recovery cell is defrozen by using the preheater. The power of the
preheater is mainly adequate to keep the heat recovery cell defrozen. In extreme conditions, if the power of
the preheater is not sufficient, the supply fan power will be reduced or stopped by the freezing protection
thermostat when the exhaust air temperature drops below the set value (0°C). The supply fan starts when
the exhaust air temperature rises above the set value.
Under extreme conditions (humidity /harsh cold) the HR-element may freeze over and the anti-freeze
protection defreezing cycles
are not able to defrost it. If such a case occurs, the machine has to be stopped,
opened and the cold flow stopped and the ice given the necessary time to melt. Check the drainage of
condensing water! In case the water-lock dries out and makes pulping noise, you can pour 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
°
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 isolation.
