ACCESSORIES
Electrical pre-heating element
(Frost protection)
An electrical pre-heating element heats up the outdoor air before it enters the unit.
This avoids having to defrost the unit, resulting in a loss of power.
There are temperature sensors supplied to be fitted in the ducts.
EM-box
An EM-box allows heat recovery from the air from the range hood and thereby helps
to heat the supply air. The EM-box is equipped with a special filter which efficiently
cleans the range hood air of fat particles and thereby protects the system.
Pollen filter ISO ePM1 50-65% (F7)
A pollen filter in class ISO ePM1 50-65% (F7) can be fitted in the unit. The pollen filter
is fitted with the plate filter ISO Coarse >90% (G4).
Water trap
To prevent ”false” air being sucked into the system via the condensate drain, the
system must be fitted with a water trap. While there is water in the condensate
drain, the water trap works well. However, during the summer months when there
is no condensation of extract air, the water trap will dry out (and therefore cease
to prevent ”false” air intake). A Nilan water trap with ball prevents ”false” air flow all
year round.
Vibration absorbers
It is important to ensure that the ventilation unit does not transfer vibrations to the
building. The ventilation unit should therefore be placed on a vibration absorbing
material. Nilan can supply effective vibration absorbers to place under the ventila-
tion unit. They are sold in packs of 4.
Extension cable HMI control panel
The control panel for the ventilation unit is connected up with a short wire so it can
be installed close to the unit. If you place the unit so the control panel is out of sight,
for instance in a cupboard or in the loft, you can order a 15 m extension cable with
plug. This allows you to place the control panel where it is visible to the user.
It is important that the control panel is visible so the user can see alarms when, for
example, filters need replacing.
