Assembly

ERS 30 must be placed on a stable surface to minimise the risk of vibrations.

• Wherever the unit is located, any joists that back onto a sound-sensitive room should be fitted with soundproofing.
• Condensation water comes from the HRV unit. A condensation outlet with a water seal must be installed and routed to an internal drain.
• The HRV unit's installation area always has to have a temperature of at least -25^ircC and max. 50^ircC .

Ventilation connections

Condensation water drain

ERS 30 can produce several litres of condensation water per day. It is therefore important that the condensation outlet is correctly executed and the HRV unit installed horizontally.

Check that the water seal is airtight and rmly in position. The connection must be made so that the user can check and top up the water seal, without opening ERS 30.

The connection for the condensation outlet measures 015 mm.

If the HRV unit will be installed in a cold area, the condensation water drain pipe must be insulated so the condensation water in the pipe does not freeze. It is also recommended that the water seal is mounted in a warm area to guarantee that the water in the water seal does not freeze. If it cannot be guaranteed that insulation will protect the condensation water drain pipe against frost, a thermostat-controlled heating cable must be installed around the condensation water drain pipe. The installation from the water seal to the drain must be carried out with a requisite slope of at least 1%.

CLEANINGTHECONDENSATIONWATER DRAIN

Condensation forms when ERS 30 is working. This condensation is led off and collected in the condensation water drain. Apart from water, a certain amount of dust and particles also collect there.

Check regularly that the condensation water drain and any oor drains are not blocked; water must be able to run through freely. Clean, if necessary.

NOTE

During operation, negative pressure arises in the HRV unit, which means that a water column of at least 100 mm must be guaranteed in the water seal.

General ventilation connectionsAdjusting ventilation

• Ventilation installation must be carried out in accordance to obtain the necessary air exchange in every room of the building, the exhaust air valve and the supply air inlet as well as the fans in the HRV unit must be correctly positioned and adjusted.
• Provision must be made for inspection and cleaning of the duct.
• The air duct system must be a minimum of air tightness class B. Immediately after installation adjust the ventilation so that it is set according to the projected value of the house.
• To prevent fan noise being transferred to the ventilation devices, install silencers in suitable locations in the duct system. Incorrect adjustment of the ventilation may lead to reduced installation eciency and thus poorer operating economy, a poorer indoor climate and moisture damage in the building.
  • The extract air and outdoor air ducts are insulated using diusion-proof material along their entire lengths. Outdoor air Exhaust air
• Ensure that the condensation insulation is fully sealed at any joints and/or at lead-in nipples, silencers, roof cowls or similar.
• The air must be routed to the outdoor air duct through an outer wall grille in the facade. The outer wall grille must be installed so that it is protected from the weather and must be designed so that no rainwater and/or snow can penetrate the facade or follow the air into the duct.
• When positioning the outdoor air and extract air hood/grille, bear in mind that the two air ows must not short circuit to prevent the extract air from being drawn into ERS 30 again.
• A duct in a masonry chimney stack must not be used for extract air or outdoor air.

EXHAUST AIR DUCT /KITCHEN FAN

Exhaust air duct (kitchen fan) must not be connected to ERS 30.

To prevent cooking odours from being led to the ERS 30, the distance between the kitchen fan and the exhaust air valve must be taken into consideration. The distance must not be less than 1.5 m, but may vary between dierent installations.

Always use a kitchen fan when cooking.

Ventilation ow

Connect ERS 30 so that all the exhaust air, except kitchen duct air (kitchen fan), passes through the heat exchanger (EP26) in the product.

The ventilation flow must comply with the applicable national standards.

The supply air ow must be lower than the exhaust air ow to prevent over pressure in the house.

Set the ventilation capacity in the main product's menu system (menu 7.1.4 - "Ventilation").

Electrical connection

NOTE

All electrical connections must be carried out an authorised electrician.

Electrical installation and wiring must be carried out in accordance with national provisions.

ERS 30 must not be powered during installation

Assembly

ERS 30 must be placed on a stable surface to minimise the risk of vibrations.

• Wherever the unit is located, any joists that back onto a sound-sensitive room should be fitted with soundproofing.
• Condensation water comes from the HRV unit. A condensation outlet with a water seal must be installed and routed to an internal drain.
• The HRV unit's installation area always has to have a temperature of at least -25^ircC and max. 50^ircC .

INSTALLATION AREA

Leave a free space of 600 mm in front of the product.

NOTE

Ensure that there is sucient space (300 mm) for connecting ventilation ducts.

Ventilation connections

Condensation water drain

ERS 30 can produce several litres of condensation water per day. It is therefore important that the condensation outlet is correctly executed and the HRV unit installed horizontally.

Check that the water seal is airtight and rmly in position. The connection must be made so that the user can check and top up the water seal, without opening ERS 30.

The connection for the condensation outlet measures 015 mm.

If the HRV unit will be installed in a cold area, the condensation water drain pipe must be insulated so the condensation water in the pipe does not freeze. It is also recommended that the water seal is mounted in a warm area to guarantee that the water in the water seal does not freeze. If it cannot be guaranteed that insulation will protect the condensation water drain pipe against frost, a thermostat-controlled heating cable must be installed around the condensation water drain pipe. The installation from the water seal to the drain must be carried out with a requisite slope of at least 1%.

CLEANINGTHECONDENSATIONWATER DRAIN

Condensation forms when ERS 30 is working. This condensation is led off and collected in the condensation water drain. Apart from water, a certain amount of dust and particles also collect there.

Check regularly that the condensation water drain and any oor drains are not blocked; water must be able to run through freely. Clean, if necessary.

NOTE

During operation, negative pressure arises in the HRV unit, which means that a water column of at least 100 mm must be guaranteed in the water seal.

General ventilation connectionsAdjusting ventilation

• Ventilation installation must be carried out in accordance to obtain the necessary air exchange in every room of the building, the exhaust air valve and the supply air inlet as well as the fans in the HRV unit must be correctly positioned and adjusted.
• Provision must be made for inspection and cleaning of the duct.
• The air duct system must be a minimum of air tightness class B. Immediately after installation adjust the ventilation so that it is set according to the projected value of the house.
• To prevent fan noise being transferred to the ventilation devices, install silencers in suitable locations in the duct system. Incorrect adjustment of the ventilation may lead to reduced installation eciency and thus poorer operating economy, a poorer indoor climate and moisture damage in the building.
  • The extract air and outdoor air ducts are insulated using diusion-proof material along their entire lengths. Outdoor air Exhaust air
• Ensure that the condensation insulation is fully sealed at any joints and/or at lead-in nipples, silencers, roof cowls or similar.
• The air must be routed to the outdoor air duct through an outer wall grille in the facade. The outer wall grille must be installed so that it is protected from the weather and must be designed so that no rainwater and/or snow can penetrate the facade or follow the air into the duct.
• When positioning the outdoor air and extract air hood/grille, bear in mind that the two air ows must not short circuit to prevent the extract air from being drawn into ERS 30 again.
• A duct in a masonry chimney stack must not be used for extract air or outdoor air.

EXHAUST AIR DUCT /KITCHEN FAN

Exhaust air duct (kitchen fan) must not be connected to ERS 30.

To prevent cooking odours from being led to the ERS 30, the distance between the kitchen fan and the exhaust air valve must be taken into consideration. The distance must not be less than 1.5 m, but may vary between dierent installations.

Always use a kitchen fan when cooking.

Ventilation ow

Connect ERS 30 so that all the exhaust air, except kitchen duct air (kitchen fan), passes through the heat exchanger (EP26) in the product.

The ventilation flow must comply with the applicable national standards.

The supply air ow must be lower than the exhaust air ow to prevent over pressure in the house.

Set the ventilation capacity in the main product's menu system (menu 5.1.5).

Electrical connection

NOTE

All electrical connections must be carried out an authorised electrician.

Electrical installation and wiring must be carried out in accordance with national provisions.

ERS 30 must not be powered during installation

NOTE

If the supply cable is damaged, only NIBE, its vice representative or similar authorised person may replace it to prevent any danger and dam
