General information
Introduction
General information prior to installation
The following documents are supplied with the unit:
• Installation instructions/Software instructions
• User manual
• Wiring diagram
The instructions can be downloaded from the Nilan website: http://www.nilan.dk/da-dk/forside/
download
If you have further questions on unit installation after reading the instructions, contact your nearest
Nilan distributor, who can be found on www.nilan.dk/forhandlere.
The purpose of these instructions is to give the installer advice on correct installation and maintenance
of the unit.
The unit must be started up immediately after installation and connection to the duct system. In
periods where the ventilation system is not in operation, humid air from the rooms may penetrate into
the ducts and form a condensate. The condensate may leak out of the valves and damage furniture and
floors. In addition, condensate may form inside the unit, damaging the unit's electronics and fans.
The unit is supplied fully tested and ready for operation.

Unit type
Product description
Comfort 200 Top is a ventilation unit with heat recovery. The unit is designed for air flows up to 308
m3/h at 100 Pa external duct pressure.
The unit draws the humid, vitiated air out of the dwelling via the bathroom, WC, kitchen and utility room
and introduces fresh outdoor air into habitable rooms such as living room, bedrooms and office. The
cold outdoor air is heated up in the heat exchanger by the warm exhaust air.
Comfort 200 Top is supplied as standard with a G4 filter in the outdoor air and extract air ducts. If it is
wished to filter the outdoor air for pollen, an F7 filter can be purchased as an accessory and mounted
subsequent.

Accessories
Electrical preheating element for frost protection
In longer periods of sub-zero temperatures, the high-efficiency counterflow heat
exchanger will ice up. To avoid icing, it is recommended that an electrical
preheating element is mounted.
The preheating element uses very little energy, but ensures efficient heat
recovery without de-icing, thus achieving an overall saving in energy
consumption.
Adjustable water comfort heater
A water comfort heater can be used to increase supply air temperature to the
desired level. It is fitted in the supply air duct and must be connected to the
primary heat supply.
Supplied with a two-way regulating valve, temperature sensor and frost
thermostat.
Electric heating element
An electric heating element allows the supply air temperature to be raised to the
desired level. Electric heating elements are supplied for mounting in the supply
air duct, and are provided with the necessary sensors.
EM box
With an EM box it is possible to divide the extract air between the kitchen and
bathroom.
If the cooker hood is operating via the unit and is switched on, air extraction from
the bathroom reduces slightly to allow sufficient air for the cooker hood to
extract kitchen fumes.
The EM box has a metal filter which efficiently separates grease particles from
the cooker hood air, thus protecting the unit.
DBTU damper
If there is not enough space to fit an EM-box, Nilan offers a DTBU damper, which
can be fitted between kitchen and bathroom. The damper functions precisely like
the EM-box but requires longer cables.

Pollen filter F7
The unit is supplied as standard with a G4 filter.
If persons in the dwelling suffer from a pollen allergy, there is an option for
mounting a F7 pollen filter in the outdoor air inlet to minimise the pollen in the
indoor air.
Water trap
To ensure that the condensate can drain off freely, a water trap must be
established.
The water trap must be regularly checked for water. In the summer season,
where no condensation will occur, there is a risk of the water trap drying out. The
Nilan water trap contains a ball which cease to prevent "false" air intake into the
unit, so that condensate can run freely out of the unit.
Vibration absorbers
4 pc. of vibration absorbers are placed under the unit and secure an effective
dimming of the vibrations of the unit againt the surface.
Flexible silencing
To facilitate later servicing of the unit, we recommend fitting a flexible
connection between the unit and the duct system.
Nilan's sound damping flexi-hose gives good sound damping both to the duct
system and to roof stacks.
CO2sensor
Fitting a CO2sensor means the ventilation speed can be pre-programmed to run
higher ventilation levels in the event of high CO2level in the extracted air. CO2
levels can be programmed.
Installation of the CO2sensor must ordered from the factory.

Installation
Mounted
Placement of the unit
ATTENTION
When fitting the unit you should always take future service and maintenance in consideration.
It must be easy to replace the filters and ef it must be possible to take out the heat exchanger,
fan or other components.
ATTENTION
A minimum distance of 60 cm in front of the unit is recommended for workspace.
ATTENTION
The unit must be installed level for the sake of the condensate drain.
The unit is low-noise and low-vibration. However potential vibrations spreading from the unit to the
individual building parts must be taken into account. To detach the system from the floor, we
recommend that the system is placed on vibration absorbers. To other building parts and other fixtures
there should be a distance of about 10 mm.
The unit can be installed both inside and outside the building envelope because it is isolated and meets
the requirements for heat loss.

Plumbing
Condensation drain
Important information
The unit is supplied with dia. 20 mm condensate drain (PVC, GF-fittings).
ATTENTION
Awater trap must be established in the condensate drain in order to ensure that condensate
can drain off.
ATTENTION
If the unit is assembled outside the climate screen, it is important to secure the condensate
drain against icing with a heating cable. Frost protection of the unit is the installer's
responsibility.
During operation, a underpressure of up to 500 Pa may develop in the drain, corresponding to
50 mm water column. This water trap must therefore be mounted as shown in order to prevent
drying out and return flow.
The connection of the water trap must be air-tight, otherwise air will be let into the unit and
condensate will remain in the unit. This could lead to water damage if the condensate overflows
the condensate tray and from there out of the unit.
After mounting the water trap, its function is tested as follows (the unit must be connected to
the duct system and the lid must be closed).
The condensation tray are filled with water and the unit is operated at the highest fan speed.
Allow it to run for several minutes. Check that there is no water in the condensation tray when
the test is finished.
The water trap may dry out and thus prevent water escaping from the condensate tray, as air
will be sucked into the unit. The water trap should therefore be checked at regular intervals,
especially in the summer, and filled with water as necessary. Increasing the height of the water
trap compared to the minimum requirements will minimize the need tor refilling.
INFO
Nilan offers a water trap with a ball. The ball ensures that no air is sucked into the unit through
the condensate drain if the water trap dries out. This ensures that water in the condensate tray
can drain off and it makes it unnecessary to check the condensate drain so often.
