BUILDING THE VENTILATION
SYSTEM
Designing the ventilation system must be done by a
professional ventilation designer. By following closely
the design plan when building the ventilation system,
you ensure the operation of the whole ventilation
system and customer satisfaction. Use the Enervent
Energy Optimizer calculation program at the Enervent
home page to calculate the performance and estimated
heating/cooling power of a particular ventilation unit.
• Use type-approved factory made materials when
building the ventilation system.
• Use valves that are suitable for mechanical
ventilation.
• Do not cover the outside air grating with mosquito
net.
• This would make it very dicult to keep clean.
• Prevent rain water and snow from entering the
outside air and exhaust air duct.
• Install enough inspection hatches in the
ventilation network to enable cleaning of the
ventilation ducts.
• To make it easier to nd the inspection
hatches, mark their location for example on
the rafters.
• Ventilation systems for dierent re areas must be
separate.
• For example garage is one re area whereas
living quarters are another re area, which
means that they cannot be connected to the
same ventilation system.
• Use an extractor hood with its own fan, above the
stove.
• The extractor hood must have its own extract
duct directly out.
• A motorless extractor hood can be connected
to the ventilation unit only if the ventilation
unit has an extractor hood connection.
• The extractor hood used must be equipped
with a grease lter and a timer controlled ap
that prevents any airow through the extractor
hood when not in use.
• A drying cabinet with its own fan can be indirectly
connected to the outlet valve using the connection
system of the drying cabinet.
• A part of the extract air is taken from the living
space and a part from the drying cabinet.
• The extract air must ow through the valve at
a speed of 12 litres / second minimum.
• Install silencers at least in the supply and extract
ducts.

11Installation instructions
EN
• The amount of silencers must be considered
case by case.
• We recommend that automatically closing
dampers are installed in outside and exhaust air
ducts.
• In case of a power failure, the dampers will
close and block out cold air, preventing any
water coil from freezing.
• If cold air gets into ventilation ducts, it will
create condensate when mixing with warm air.
NOTE: The ventilation ducts must be blanked
o until the ventilation system is taken into use.
This is in order to keep warm air from owing
into the duct. Warm air causes condensation if
it meets cold outside air or surfaces in the duct.
Furthermore the plugging keeps dirt and other
unwanted particles from clogging the system.
Insulating ventilation ducts
Insulate the ventilation ducts appropriately. This is
especially important when the ventilation unit comes
with a cooling functionality.
Ventilation ducts must be thermally insulated to
prevent water from condensing to the inner or external
duct surfaces in any circumstances. Additionally, the air
temperature must not decrease or increase excessively
in the ducts because of external factors. The ventilation
engineer calculates the insulation requirements
depending on the placement of the ducts and the air
temperatures.
Ventilation duct thermal insulation in heating use
Supply air duct from
the ventilation unit to
the supply valve.
The insulation must be designed
and implemented so that the
maximum air temperature change
in the duct is less than 1°C.
Extract air duct from
the extract valve to
the ventilation unit.
The insulation must be designed
and implemented so that the
maximum air temperature change

Ventilation duct insulation
examples
NOTE: Sound insulation is not taken into
account in these insulation instructions and
examples.
NOTE: Semi-warm space = +5°C - +15°C. A
semi-warm space refers also to dropped ceilings,
sub-oors, and casings.
Outside air duct (fresh air duct)
Cold spaces
• 100 mm of sheet, mat, or pipe-covering insulation
(plus the blown wool, when used).
Warm/semi-warm spaces, dropped ceilings, sub-
oors, and casings
• Option 1
• 80 mm insulation with vapour-proof external
surface.
• Option 2
• 20 mm of cellular rubber insulation on the
duct surface and 50 mm insulation with
vapour-proof external surface.
The insulation must prevent water vapour from
condensing to the external duct surface and excessive
air temperature rise during summer.
Supply air duct
Cold/semi-warm spaces and also by dropped
ceilings, sub-oors, and casings:
• In standard ventilation the insulation must be
designed and implemented so that the maximum
air temperature change in the duct is less than 1°C.
• For example, 100 mm of sheet, mat, or pipe-
covering insulation can be used (plus the blown
wool, when used).
Warm spaces
• Insulation is not required in standard ventilation.
In heating and cooling use see tables "Ventilation duct
thermal insulation in heating use" on page 11 and
"Ventilation duct thermal insulation in cooling use" on
page 11.

• Option 2
• 20 mm of cellular rubber insulation on the
duct surface and 50 mm insulation with
vapour proof external surface.
The insulation must prevent water vapour from
condensing to the external and internal duct surfaces.
Extractor hood duct
• The extractor hood duct must be insulated and
constructed in accordance with local building and
re safety regulations.
Installing duct coils
Duct coils are used in several unit models both as pre-
heaters, after-heaters and coolers. For information what
type of coils are used with your ventilation unit model,
refer to tables listing models with duct coils at the end
of this manual. For correct mounting of duct coils, refer
to the principal diagrams at the end of this manual.
Ventilation unit models equipped with duct coils for
after-heating or cooling (see table "Models with duct
coils" on page 36).
• These coils are installed in the supply air duct (after
the ventilation unit).
Ventilation unit models equipped with pre-heating/pre-
cooling coils (see table "Pre-heating and pre-cooling
coils" on page 37).
• These coils are installed in the outside air duct
(before the ventilation unit).
• Duct coils must be accommodated in the
ventilation ducts.
• There must also be sucient room for
maintenance and draining of condensate water.
NOTE: For more technical details about the
coils, see the technical data table at the end of
this manual.
Duct coil for uids
When installing duct coils:
• Place the duct coil in the supply air duct after the
ventilation unit or in the outside air duct before
the ventilation unit depending on its function.
• Make sure that there is a lter before pre-heater
coils in the outside air duct to prevent dirt from
entering the coil.
• Do not install the coil too close to a fan outlet or a
bend in the ducting.
• This can result in lower eciency.
• Connect the coil so that the system is easy to
empty for maintenance.
• Install duct heaters in a horizontal or a vertical duct
with optional direction of airow.
• To facilitate venting of the coil, the unit
must be tted with the longitudinal tubes
horizontal.
• Install duct coolers in a horizontal duct with airow
in the direction of the arrow.
• Insulate the cooler externally to prevent the
formation of condensation.
• Connect the cooler to a condensate drain
and water trap and tilt it at an angle of 10-15
degrees to the horizontal in the direction of
the drain.
• Insert the coil into standard spiral ducting and
attach it to the ducting with screws.
• Support the weight of the coil.
• Connect the coil with clamping ring
connectors.

13Installation instructions
EN
• Connect the water inlet to the lowest pipe
connector in order to facilitate venting of the coil.
• Consult the principal drawings at the end of
this manual on how to construct the hydronic
circulating system.
• Install a venting valve near the coil or at the
highest point in the system.
• Inspect the duct coil and its connections for leaks
immediately after the system has been lled with
liquid.
• Place the supply air temperature sensor (TE10) in
the duct after the coil.
• Place the water coil return water sensor (TE45)
on the return water pipe of the coil, if the coil is
mounted in the supply air duct.
• Place the outside air temperature sensor (TE01)
in the outside air duct before the coil, if the coil is
mounted in the outside air duct.
• Connect the sensor to the ventilation unit control
circuit board.
• Refer to the electrical schematics at the end of this
manual for correct connections.
Electrical duct coils
NOTE: The heater is designed for insertion
into standard spiral ducting and is xed to the
ducting with screws.
NOTE: The air must ow through the heater in
the direction indicated by the arrow on the side
of the connection box.
To install:
• Install the heater in either horizontal or vertical
ducting.
• The heater must only be tted in ducts that
are made of incombustible and heat-and-cold
resistant material.
• The connection box can be freely placed
facing upwards or sideways to a maximum
angle of 90°.
CAUTION
CAUTION: Do not install the connection box
facing downwards.
• The distance from (to) the heater to (from) a duct
bend, valve, lter, etc., must be at least twice the
duct diameter.
• Otherwise there is a risk that the airow
through the heater will be uneven which can
cause activation of the overheating cut-out.
• Insulate the duct heater in accordance with local
regulations for ventilation ducting.
• Make sure that the insulation is incombustible.
• Do not cover the lid with insulation, since the
rating plate must be visible and the lid must
be removable.
• Do not cover any heatsinks, nor the side of the
connection box where the SCR’s (Triac’s) are
mounted with insulation.
• The duct heater must be accessible for
replacement and inspection.
• Make sure that the distance from the heater metal
casing to any wood or other combustible material
is at least 30 mm.
• Install the duct sensor TE10 (delivered with the
heater) in the duct after the heater, if the heater is
mounted in the supply air duct.
• If the heater is mounted in the outside air duct,
install the temperature sensor (TE01) before
the heater in the outside air duct and connect
the sensor(s) to the ESC control circuit board.
NOTE: We recommend installing a safety switch
for the electric heater.
Installing ventilation unit ceiling
installation plate (OPTIONAL)
NOTE: Ceiling installation plate is separately
sold extra equipment available for ventilation
unit models Pinion, Pingvin, Pingvin XL and
Pandion.
Before installation:
• Make sure that the ceiling is even so that the plate
will be stable and straight when installed.
• The gap between the plate and the back wall must
be at least 10 mm (recommendation) and at least
15 mm between the plate and the side walls.
• The ceiling installation plate top surface must
not be more than 15 mm above the ceiling inner
height.
• Otherwise you will not be able to hook
the ventilation unit front on to the ceiling
installation plate.

14
To install:
1. Prepare the holes in the ceiling for the ventilation
ducts.
2. Attach the plate on the ceiling using screws that
are suitable for the ceiling material.
3. Seal the ceiling installation plate against the
ceiling’s vapor barrier using for example duct tape.
4. Attach the ducts to the ceiling installation plate
with rivets.
• Make sure that there are no gaps between the

Installing geo-cooling equipment
If a geothermal heat pump is in use, the cold brine in
the ground loop can be used in the summertime to
cool the incoming air.
The system can be implemented in two ways:
• In a standard delivery, a separate pump is used
(Option 1).
• Alternatively, the brine is circulated through the
geothermal pump (Option 2).
The cooling coil can be either built in the ventilation
unit or it can be a duct coil, depending on the model.
A duct coil is mounted in the supply air duct after the
ventilation device.
Detailed principal charts are found at the end of this
manual.
Option 1 (standard)
A separate pump is used for circulating brine in the
supply air coil.
The delivery includes:
• A relay for starting up the circulation pump for the
ventilation unit’s cooling coil.
• The relay is situated on the unit motherboard
connection DO8.
• A 3-way control valve (Belimo R3) needed for
cooling.
• An actuator (Belimo TR24-SR).
The temperature is controlled using the ventilation
unit’s own automatic control. The ventilation unit
controls the circulation pump and the 3-way valve.The
heat pump is not started up for ventilation cooling.
To install:
1. Install the cooling coil in the supply air duct (in
case of a duct coil).
2. Connect the condense water outlet.
3. Build a separate pump group with valve and
actuator for circulating cool brine adjacent to the
ventilation unit cooling coil.
4. Isolate the pipes carefully with vapour proof
insulation to prevent condensation on the outside
of the pipes in warm and semi-warm spaces.
• Follow the principal chart at the end of this
manual.
NOTE: The valve and actuator must be in the
same position when connected. When the valve
is in the open position, the actuator is turned
counter-clockwise before connecting, and
when the valve is closed, the actuator is turned
clockwise before connecting. Figure 1 on page
15 shows the valve and markings on valve
spindle in valve open (cooling/heating on max)
position.
5. Prepare / connect wiring between the ventilation
unit, the geothermal pump and the actuator, as
shown in the connection diagram at the end of
this manual.
Option 2
A geothermal heat pump is used for circulating brine
also in the supply air coil.
The delivery includes:
• A relay for starting up the brine pump.
• The relay is situated on the unit motherboard
connection DO8.
• A 3-way control valve (Termomix D32S) needed for
cooling.
• An actuator (Belimo NRYD24-SR-W + installation
set MS-NRE).
The temperature is controlled using the ventilation
unit’s own automatic control. The ventilation unit
controls the geothermal heat pump and the 3-way
valve.
To install:
1. Install the cooling coil horizontally in the supply air
duct (in case of a duct coil).
2. Isolate a separate loop for the cooling coil.
• Make sure to include the one-way valve.
• Follow the principal chart at the end of this
manual.
3. Connect the condense water outlet.
4. Install the 3-way valve and the actuator in the
ground collector’s piping.

• The actuator controls the brine ow to the
cooling coil as needed.
5. Isolate the pipes carefully with vapour proof
insulation to prevent condensation on the outside
of the pipes in warm and semi-warm spaces.
Figure 1. Valve and actuator open counter-clockwise and
close clockwise. The gure shows the valve and actuator
in the fully open position. Also, shown is the allowed direc-
tion of the liquid ow.
NOTE: The valve and actuator must be in the
same position when connected. When the valve
is in the open position, the actuator is turned
counter-clockwise before connecting, and
when the valve is closed, the actuator is turned
clockwise before connecting. Figure 1 above
shows the valve and markings on valve spindle
in valve open (cooling/heating on max) position.
6. Prepare / connect the wiring between the
ventilation unit, the geothermal pump and the
actuator.
Installing CHG geothermal pre-
heating / pre-cooling equipment
A geothermal pre-heating / pre-cooling coil for
improving the system energy eciency can be installed
in the ventilation system. A duct coil is always used
when a hydronic pre-heating coil is needed. The coil is
installed in the outdoor air duct before the ventilation
unit. The duct or the coil must have a lter to keep dirt
out of the coil.
To avoid freezing the coil, the brine used in the coil
system must meet the local rated temperature value.
• For example in Helsinki, the brine must still
be functional at -26°C whereas in Lapland the
temperature value is -38°C.
It is also possible to use earth to air heat exchangers
(earth tubes) for pre-heating or pre-cooling. The earth
tube must be combined with a normal outside air
duct and a damper that switches the outside air ow
between the earth tube and the normal outside air
duct depending on the actual need for pre-cooling and
pre-heating. The damper can be controlled from the
same relay that controls the circulation pump for the
hydronic pre-cooler / heater.
The CHG pre-heating / pre-cooling system can be built
as a separate system (option 1) or as a part of the geo-
thermal heat system (option 2).
Detailed principal charts are found at the end of this
manual.
Option 1
A ground loop is built for the pre-heating / cooling
coil. To avoid freezing of the system, brine in the
loop must meet the local rated temperature value.
The ventilation unit automatic control regulates the
system’s temperature. The ventilation unit controls the
circulation pump and the 3-way valve.
To install:
1. Install the cooling / heating coil in the outside air
duct.
2. Connect the condense water outlet.
3. Build a separate pump group for circulating cool
brine adjacent to the ventilation unit cooling /
heating coil.
4. Isolate the pipes carefully with vapour proof
insulation to prevent condensation on the outside
of the pipes in warm and semi-warm spaces.
5. Prepare / connect wiring between the ventilation
unit, the circulation pump and the actuator.
6. Install and connect the outside air temperature
sensor (TE01) in the outside air duct before the
duct coil.
• Refer to the electrical connection diagrams at
the end of this manual.
Option 2
A separate loop is isolated from the geothermal pump
brine loop for the cooling coil. To avoid freezing the coil,
brine in the loop must meet the local rated temperature
value. In addition to this, a heat exchanger is installed
in the coil system to ensure the functionality of the
geothermal pump. For the pre-heating / pre-cooling
coil to yield any benets there must be some ow in the
collector of the geothermal pump.

16
Temperature is controlled using the ventilation unit’s
own automatic control. The ventilation unit controls the
circulation pump and the 3-way valve.
To install:
1. Install the cooling coil in the outside air duct.
2. Connect the condense water outlet.
3. Build a separate pump group for circulating cool
brine adjacent to the ventilation unit cooling coil.
4. Isolate the pipes carefully with vapour proof
insulation to prevent condensation on the outside
of the pipes in warm and semi-warm spaces.
5. Install a heat exchanger in the coil system.
6. Install and connect the outside air temperature
sensor (TE01) in the outside air duct before the
duct coil.
7. Prepare / connect wiring between the ventilation
unit, the geothermal pump and the actuator.
