Safety
Power supply
CAUTION
Always disconnect mains electricity to the unit if a fault occurs which cannot be rectified via the
control panel.
CAUTION
If a fault occurs on the electricity-conducting elements of the unit, always contact an
authorised electrical installer to rectify the fault.
CAUTION
Always disconnect mains electricity to the unit before opening the doors, e.g. for installation,
inspection, cleaning and filter change.
Disposal
Ventilation system
Nilan units mainly consist of recyclable materials. They should therefore not be
disposed of with household refuse. Take them to your local recycling centre.

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.
