Air Circulation - Trotec DH 150 Mode D'emploi

2.2 AIR CIRCULATION

It is important that you ensure that the air is distri-
buted evenly throughout the room in order to ensure
that the humidity is drawn out of the ambient air as
effectively as possible and that the humidity value you
have selected is maintained constantly . Your dehumi-
difier must be able to draw in moist air and distribu-
te the air which has been dried to areas which are
commonly affected by high levels of moisture (e . g .
windows) . This is why your dehumidifier is equipped
with special ventilation channels and ducts .
m
the drier and the ventilation channels work
at normal temperatures. If they come into
contact with unheated rooms because the ventilati-
on channels are conducted through unheated cellars
or attics for example, then these channels must be
insulated accordingly.
Drawing in air from moister areas:
The moist air must be fed into the drier in as small
amounts as possible . There is no need for ventilation
channels if the dehumidifier is placed in an adjoining
room .
Discharging dry air back into the room:
You will find that it is often necessary to install ventila-
tion channels to ensure that the dried air is distributed
as evenly as possible . See the technical data sheet to
find out which ventilation channels, ventilation grilles,
grilles and air heating batteries are suitable for which
specific quantities of air and which different pressure
values .
IMpOrtant nOtes:
• It must be ensured that the nozzle which measures
the relative humidity at the air intake duct is also
able to measure the moisture from any installed
ventilation channels (see installation plan) .
• All models are standard equipped with a nozzle for
the discharged air .
• The air discharge nozzles and air filters are available
from specialist stores . DO NOT drill into the unit to
fit either the nozzle or air filter .
EN
• A flexible adapter made of rubber or fabric should
be placed between the ventilation channels and the
nozzle to prevent any vibrations from being transferred .
• Remove any cover lids or air grilles before the air
ventilation channels are connected .
• Check the unit, the grilles and the airflow thoroughly
when you have completed installing the unit . The
air flow must correspond to the amount stated
on the technical data sheet (± 10 %) and should be
adjusted, if necessary, using the main sluice valve .
If the air flow does not correspond to the prescribed
amount, then the performance of your dehumidifier
will not be achieved .
• TABLE 1 . Open space which is necessary to ensure
that sufficient air flow is guaranteed when the unit
is installed in a separate room and wall break-
throughs are planned .
Model DH150:
Minimum open space air inlet amount = 0 .35 m² .
Model DH300:
Minimum open space air inlet amount = 0 .57 m² .
Model DH600:
Minimum open space air inlet amount = 1 .1 m² .

necessary to ensure that the dehumidifiers per-
form as intended can be added together to form a
common air inlet opening. the air discharge ducts
should be connected to separate ventilation chan-
nels or separated by nonreturn valves in order to
prevent the air from flowing back into other ma-
chines.
