Equipment requirements and installation location
The dehumidifier AD must be installed vertically inside a building fitted with a solid and level flooring
and be fastened securely to the floor.
Leave a space of 1000mm on the inspection side of dehumidifier for maintenance, replacement of filters.
Connecting channel
The dehumidifier can be installed inside or outside the room, which is going to be dehumidified. To
improve the performance of the installation is recommended to remove the flow from the air intake.
General instructions
The connections for the process air and the reactivation one are designed in accordance with ISO 13351.
The connections of rectangular ducts contain inserts to secure the screws M8.
NOTE!
The dehumidifier is designed for specific process air-flows, which correspond to the dimensions
of the fans installed and must not be connected to existing air conditioning systems.
Upon installation of the network of ducts between the dehumidifier and the inlet and outlet connections
for inlet and outlet, observe the following guidelines
:
The length of the network of ducts must be minimal in order to limit the pressure drops.
For best performance, all stiff joints of process and reactivation air ducts must be sealed for air
and steam.
The process air duct must be isolated in order to avoid the formation of condensation on the
outside, if the temperature inside the duct falls below the dew point of the ambient air.
If there is a risk of sub-zero temperatures, the ducts must be insulated
.
The high rate of humidity of the air, issued by the unit, it could cause condensation of water inside
the ducts. By insulating the ducts the amount of condensate decreases
.
The horizontal ducts of moist air must be installed with a slight slope (away from the
dehumidifier) for the drainage of any condensate.
In correspondence of the lowest points of the
exhaust duct of the moist air devices shall be installed to drain the condensate.
The moist air duct
must be made of anticorrosive material (for example, stainless steel, aluminum, plastic, etc.) And
it must withstand temperatures that can reach 100 °C
.
The ducts must be designed so as to prevent the infiltration of rain or snow in the dehumidifier
.
To reduce the transmission of vibration and/or noise along the rigid ducts, the installation of
flexible watertight joints and any silencers is recommended.
The ducts mounted directly on the dehumidifier must be equipped with suitable support to
reduce the load and the voltage due to the weight and movement of the ducts themselves.
You must install the manual dampers on the flows of the process and reactivation air, to maintain
the functional efficiency of the unit
The total pressure drop of the process and reactivation air ducts should not be higher than the
available pressure of the fans.
Specification for the expulsion channel of moist air
The humid air from the dehumidifier must be expelled outside.
The channels must be as short as possible
to minimize the possibility of condensation of moist air within them
.
This channel should be slightly
