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/en-gb/frontpage/download/dealers.
The purpose of these instructions is to give the installer advice on correct installation and maintenance
of the unit.
ATTENTION
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 CT150 / CT200 is a ventilation unit with heat recovery. It is useable for air volumes up to 175 /
200 m 3 /h at 100 Pa external duct pressure.
The unit extracts humid and poor quality air from the home via the bathroom, toilet, kitchen and utility
room, and blows fresh air into rooms such as the lounge, bedrooms and office. Cold outdoor air is
heated in the heat exchanger by the warm extracted air.
Comfort CT150 / CT200 comes as standard with a plate filter for outdoor air and extract air. If you
want to filter pollen from outdoor air, a pollen filter is available for retrofitting.

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.
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.
Pollen filter
The unit is supplied as standard with a plate filter.
If persons in the dwelling suffer from a pollen allergy, there is an option for
mounting a pollen filter in the outdoor air inlet to minimise the pollen in the
indoor air.
A pollen filter also removes approx. 50% of the hazardous particles in the
outdoor air, so if you live in a big city or near a freeway, a pollen filter is
recommendable.
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. During the summer season,
where no condensation will occur, there is a risk of the water trap drying out. If
the water trap has dried out, air will be drawn into the unit and the condensate
cannot be drained, which will cause water damage.
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.

11

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.
Side mounted brackets for vertical mounting
For vertical mounting of the unit a wall bracket can be purchased and attached in
which the ducts can also be led and concealed. By vertical mounting the unit
works as a top-unit.
The side panels are prepared for mounting of the display panel.
Rear mounting brackets for vertical mounting
A wall bracket can be purchased and attached for mounting on the back of the
unit. By vertical mounting the unit works as a top-unit.

Installation
Mounting
Positioning of the unit
ATTENTION
When mounting the unit, consideration must always be given to future servicing and
maintenance.
It must be easy to replace filters, and it must be possible to perform tasks such as removing the heat
exchanger, replacing fans and other components.
ATTENTION
A minimum free space in front of the unit of 60 cm is recommended.
Comfort CT150 is a flexible unit which can be mounted horizontally, vertically or at an angle. However,
it is important that the exhaust is always positioned at the bottom (see illustration below).
ATTENTION
The system must be mounted in a level position. If this is not possible, there must be a decline
towards the condense water outlet.
Errors in the installation can cause moisture and water damages.
Systems that are not mounted on a walls or ceiling, MUST be mounted on a level and firm
surface.

Installation rails
Comfort CT150 is always supplied with a set of installation rails.
The rails must be mounted with a space between them of 1045 mm. The unit is then slid between them
and fixed by turning up the ends of the rails.
This is a simple and quick way of mounting the unit without having to hold it while screwing it into
position.
1045 mm
Rear installation (accessories)
It is possible to buy a mounting bracket, for mounting on the back on the unit.
It is a good solution, if the unit has to be installed vertically in a cabinet or a technical room. In this way,
the unit is converted to a "Top unit".

Side installation (accessories)
It is possible to buy a mounting bracket, for mounting on the side of the unit.
Comfort CT150 is prepared that the side bracket can be mounted on either the right or the left side.
The ducts can be lead behind the bracket, which provides a nice installation.
It is possible to mount the control panel on the side bracket in the prepared holes.
The side brackets are mounted on the wall and the unit is then hung up on the bracket.
