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.
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.

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 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.
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".

It is important that the sensor is placed at least 32 cm from the preheating element to achieve correct
regulation.
The preheating element is fitted with a three-step safety system to prevent
overheating.
1. A thermostat regulates heat and ensures that the supply air temperature does
not go below -1 °C
2. A max. thermostat switches off the preheating element if the temperature
exceeds 50 °C (By vertical installation with downwards airflow the preheating
element will be switched off at 70 °C)
3. A manual safety thermostat can be used to switch off the preheating element
if the temperature exceeds 100 °C. Then the preheating element must be reset
manually.
ATTENTION
When mounting the electric preheating element, there must be a safety gap of minimum 15 cm
from any flammable material. The heating element must be insulated with a fire retardant
insulation material, but the cover on the connection box must not be insulated.

Plumbing installation
Condensate drain
Important information
The unit is supplied with dia. 20 mm condensate drain (PVC, GF-fittings).
ATTENTION
A water 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.
