7 .1 PLACE OF INSTALLATION
The dehumidifier is suitable for indoor usage. For the convenience of
maintenance and inspection, some space around the machine should be
retained (800mm gap at least). In order to prevent condensation inside the
machine, the dehumidifier should not be put into the condition in which the air
temperature is below the dew point.
In addition, if the machine is installed outdoors, some protective measures
should be taken to prevent rain, snow and dust etc.
In any case the dehumidifier has to be installed on a horizontal ground or
platform, which has to be able to sustain the weight of it . After the
installation, it would be wise to re-check the ground or the platform on
which the dehumidifier has been placed. In case the dehumidifier has to be
mounted, the retaining base should be from stainless steel.
The dimension s of duct for process air and reactivation air should be in line
with ISO7807 recommended values. Ducting should be connected with
the connection part on flange.
Please pay attention to the following notes about the duct connection.
• In order to reduce loss of static pressure, it is advice d to install with the
shortest length of duct possible.
• In order to ensure the maximum perfomance of the machine, all connctions
have to be done right, without any loss of air.
•
The duct should have a good capacity of thermal insulation, to prevent
moisture condensation inside or outside the duct surface.
•
To reduce noise and vibration transmitted along the duct, high quality, soft
and strong airtight adapting pieces should be used in the joint parts.
• The air valve can be installed in side the duct of process air and reactivation air
if it is needed.
•
If the reactivation air is introduced from outdoor air, the reactivation air duct
should be high enough off the ground to prevent inhale of dust and debris,
meanwhile, it must be far away from some sources of pollution, such as
energy emissions, steam and gases. In order to prevent wet air outlet is
inhaled back into machine, the distance between the regeneration inlet air and
wet air outlet should be at least distant by 1 meter.
If the outlet air contains a high amount of moisture, droplets may form inside
the conduit. In this case, the drain should be positioned vertically so that the
droplets flow smoothly out of it. If installed horizontally, these droplets will
remain in the interior and may cause long-term corrosion of the pipeline.
