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.

• 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.

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

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.

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 in the duct is less than 1°C.

• 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.

The insulation must be designed and implemented so that the maximum air temperature change in the duct is less than 1°C.

• 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 pipecovering 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.

11Installation instructions

Extract air duct

Warm spaces

• Insulation is not required in standard ventilation.

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).

Cold/semi-warm spaces

• 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).

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.

Exhaust air duct

Cold spaces

• 100 mm of sheet, mat, or pipe-covering insulation.

Warm/semi-warm spaces

• 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 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 preheaters, 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 pre-heating/precooling 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.

• 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.

• 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.

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.

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.

13Installation instructions

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

insulation and the ducts.

• Consider the unit’s weight when screwing the

plate to the ceiling.

• The ceiling installation plate must be

absolutely rigid.

• Weights for all units are found in the technical

table in the end of this manual.

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).

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 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.

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.

• 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 geothermal 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.

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 direction 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 preheating / 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.

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.

• There are no unwanted objects inside

• The lters are in place and

• The condensate drain works.

9. Close the hatch carefully.

10. Connect the unit to an appropriate electric supply.

NOTE: The valve and actuator must be in the

same position when connected. When the valve is in open position, the actuator is turned counter-clockwise before connecting, and when the valve is closed, the actuator is turned clockwise before connecting. Figure 2 on page 23 shows the valve and markings on valve spindle in valve open (cooling/heating on max) position.

Figure 2. 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 direction of the liquid ow.

NOTE: Do not install the actuator so that the

manual control faces downwards.

4. Connect the water.

• Do not connect to a point where the water circulation ends for example during hot water production.

5. Check the duct coil and its connections for leaks immediately after the system has been lled with water.

• The water heating coil needs a steady ow

of suciently warm water without large temperature uctuations.

• Adjust the water ow in the heating coil

according to the technical features table at the end of this manual.

• If the water is taken for instance from a ground

source heat pump, the heating coil needs its own circulation pump.

• If the installation is done in wintertime it is

recommended not to let water in the coil until the ventilation is running. This is in order to prevent cold air from entering the ventilation system and possibly freezing the coil.

6. Connect the external cables such as the cable between the unit and the control panel, supply sensor, actuator and pump.

Draining condensate water

All Enervent ventilation units must be drained. When air cools down (condenses), condense water forms. For example in winter time when humid inside air meets cold heat recovery wheel, or when warm outside air meets the cooling coil in the ventilation unit (if applicable).

CAUTION

CAUTION: The condense water drain must not

be directly connected to a sewer pipe.

• The condensate water should be led in a falling, at least Ø15 mm pipe, through a water trap to a oor drain or such.

• The pipe must at all times lie lower than the condensate water drip pan / condensate water connection of the ventilation unit.

• There must not be any longer horizontal sections on the pipe.

• The condensation drain pipe must be insulated if mounted in spaces where freezing can occur.

• Only one water lock is allowed for each condensate water drain.

• If the unit is equipped with more than one condense water drains, each one must have a water lock of its own.

• There is underpressure in the ventilation unit. We recommend a height dierence of (A) 75 mm, or at least the underpressure divided with 10 in millimeters (i.e. 500 Pa under pressure -> 50 mm), between the unit drain and the water lock drain.

23Installation instructions

• We recommend that the height of backwater

in the water lock (B) is 50 mm, or at least the underpressure divided with 20 in millimeters (i.e. 500 Pa under pressure -> 25 mm height of backwater). The above also applies to duct coils for cooling mounted in the outside air duct or extract air duct.

• There are over pressure inside duct coils mounted in the supply air duct. We recommend the height dierence (A) between the duct coil drain and the water lock drain is 25 mm. The water lock height of backwater (B) must be 75 mm, or at least the over pressure divided with 10 in millimeters (i.e. 500 Pa under pressure -> 50 mm).

• The water lock must be lled with water before starting up the unit. The water lock might dry up if water is not accumulated in it. If this happens, air might get into the pipe and hinder water from entering the water lock, which might result in an irritating ”bubbling” sound.

• The functionality of the water lock must be checked every year before the heating season and also in the spring if the ventilation unit is equipped with cooling.

COMMISSIONING

Commissioning checklist

Requirements

For the ventilation unit to start running, it needs:

• Minimum +8 °C return water temperature (if applicable)

• Supply and extract air below +55 °C.

For the ventilation unit to stay running, it needs:

• Minimum +10 °C measured extract air temperature

• Above +5 °C heat recovery supply air

• Above +10 °C supply air temperature

• All foreign objects removed from the ventilation system.

• Both fans operating.

Calibrating airow

After the unit has been switched on, the airows must be calibrated to the planned values.

• The airow calibration is performed at start-up of the ventilation unit.

• The airow calibration is done separately for both fans for each mode selection (=fan speed) of the ventilation unit.

When calibrating, make sure that:

• All lters are clean

• All supply and extract air valves, the roof passthrough and the outside air grating are in place.

NOTE: Do not cover the grating with a

mosquito net.

To achieve optimal values during calibration the airows must be measured at each duct opening. A suitable measuring instrument is a thermo anemometer or dierential pressure meter. With the help of registered values, airow can be regulated to achieve the projected values.

A correctly calibrated ventilation unit is quiet and gives a good heat return and also upholds a small underpressure in the house. The underpressure prevents humidity from entering the walls and ceiling.

Documenting commissioning

• Fill in the warranty.

• Mark down the possible changes you made to the factory settings to the column Field settings in the table "Parameter list" on page 27.

• Fill out the air amount measuring document. A copy of the measuring document is provided at the end of this manual.

NOTE: The warranty does not apply for units

with no documented air amount measuring.

NOTE: It is very important to write down all the

changes made to the parameters. This way the information is backed up in case the automation gets damaged (for example by a lightning).
