UNIT DESIGN AND OPERATING PRINCIPLE
The unit operation is as follows: warm polluted air is extracted from indoor to the unit and is cleaned by the extract filter. Then the air
streams through the heat recovery core and is removed outside by the extract fan. The cold intake air from outside flows into the unit
and is cleaned by the supply filter.
Further the air flows through the heat recovery core and is supplied inside by the supply fan. The recovery core serves as a heat exchanger
for the warm extract air and cold intake air. The air streams remain fully isolated from each other. The heat recovery technology minimizes
heating costs during the cold season.

The removable service panel enables repair and maintenance works.
Access to the control unit for mounting and connection is made through the removable front panel of the control unit. The power and
earth cables are connected to the control unit via the cable glands.
Modications of heat recovery cores:
• HRV heat recovery core transfers sensible heat energy (temperature) from one air stream to another. The heat energy extracted from
the indoor air is transferred to the incoming fresh air, thus increasing or decreasing its temperature. The air streams remain fully isolated
from each other. This heat recovery core is made of polystyrene. Heat recovery minimizes ventilation heat losses and saves heating costs
in cold seasons and air conditioning costs in summer.
• ERV heat recovery core transfers sensible heat energy (temperature) and latent heat energy (humidity) from one air stream to another.
The latent heat energy (humidity) is transferred in the same way as the temperature. As the opposite air streams have different temperature
and humidity, they also have different surface vapor pressure. The vapor pressure difference enables transfer of the vapor pressure.
The main advantage of the energy recovery cores is the ability to recover humidity (latent energy). This energy recovery is possible
during the air conditioning and air heating seasons. During the air conditioning season, the incoming air from outside is dehumidified
and cooled down. That significantly reduces operating load for the air conditioners. During the heating season the heat recovery core
performs reverse and the incoming air from outside is humidified and heated. The heat recovery technology cuts high expenses for air
humidification and air heating.
The energy recovery core is based on polymer membrane. The membrane enables transfer of the water molecules hence they have high
dielectric constant and small sizes. The water vapor extracted from the humid air is condensed on the cold membrane surface. Water
condensation takes place at temperatures above the dew point. The liquid water molecules are moved through the membrane. The
humidity concentration differential between the warm and cold air streams enables this movement process. The humidity is vapored
away from the membrane surface and is absorbed by the dry air stream. Microbes cannot get through the membrane as their size is
much bigger compared to water molecules. Bacteria, fungi, mould and microbes cannot reproduce on the membrane material. Microbes
die on the membrane surface within several hours. The ultra thin membrane serves to decrease air speed in the heat recovery core and
increases high heat and humidity recovery efficiency.
The temperature difference between the supply and extract air streams leads to condensate formation. It is collected in the drain pan
and is removed through the drain pipe.

To attain the best performance of the unit and to minimize turbulence-induced air pressure losses while mounting connect a straight air
duct section on both sides of the unit.
Minimum straight air duct length:
• equal to 1 air duct diameter on intake side
• equal to 3 air duct diameters on outlet side
If the air ducts are not connected or the connected air ducts are too short, protect the unit parts from ingress of foreign objects by
covering the spigots with a protecting grille or other protecting device with mesh width not more than 1 /

Condensate drainage
The HRV units must be connected to a condensate drain system. The ERV units are equipped with enthalpy recovery cores with no
condensate buildup and require no condensate drain system.
The drain pan in the heat recovery unit has a drain pipe to remove condensate outside of the unit.
Connect the condensate pipe, the U-trap or a hydraulic lock of the other type (not included in the delivery) with the sewage system using
metal, plastic or rubber hoses.
While laying the hoses provide the slope downwards min 3˚. Prior to commissioning the unit make sure the water runs smoothly in the
sewage system, otherwise accumulation of the water condensate may lead to the unit malfunction and water outflow. Fill up the U-trap
with water before using it. When using other hydraulic lock systems read the installation instruction to prepare the condensate drain
system for operation.
The condensate drain system is designed for use in premises with ambient temperature above 32 °F!
If the expected air temperatures are below 32 °F, the condensate drainage system must be equipped with heat insulation and
pre-heating facilities.

SPEED SETTING
The control system enables equal speed settings or synchronous speed correcting for the supply and extract fan (see ALL).
If the air resistance differential in the supply and extract air ducts the speed of the supply and extract fan can be individually adjusted and
this setting will be saved in the controller memory (see SPL and Eht, respectively).
The controller circuit board has a digital indicator and «KEY1», «KEY2», «KEY3» buttons which are used for operation mode setup and
editing of the operation parameters. After switching on power the ventilation unit operates normally and the light indicator is off. Press
«KEY1» to open the setup menu. Select the required menu item using the buttons «KEY2» and «KEY3». The display shows the current
setting of the menu item:
• «ALL»: actual speed setting for both the supply and extract fans over the range from 0 % up to 100 % (displayed as previously set
speed setting for the supply fan). For example, in case of activated LOW-speed mode, editing of this parameter will result in change
of the low speed setting both for the supply and extract fans. To display or change this parameter press «KEY1» and set a required
value using the buttons «KEY2» and «KEY3». Then press «KEY1» to save the value in the nonvolatile memory and return to the setup
menu.
• «SPL»: activated speed setting of the supply fan displayed percentagewise over the range from 0 % to 100 %. For example, in case of
activated MEDIUM-speed mode, editing of this parameter will result in change of the supply fan MEDIUM speed setting. To display or
change this parameter press «KEY1» and set a required value using the buttons «KEY2» and «KEY3». Then press «KEY1» to save the
value in the nonvolatile memory and return to the setup menu.
• «Eht»: activated speed setting of the extract fan displayed percentagewise over the range from 0 % to 100 %. For example, in case of
activated HIGH-speed mode, editing of this parameter will result in change of the HIGH speed setting for the extract fan. To display or
change this parameter press «KEY1» and set a required value using the buttons «KEY2» and «KEY3». Then press «KEY1» to save the
value in the nonvolatile memory and return to the setup menu.
