material handling equipment such as Hand Pallet Jack, Forklift and others.
Please do not place the dehumidifier near explosive areas, it is not designed
for explosive environment or with explosive materials. When installing the
duct s , avoid recirculation of outlet air to inlet. For instan ce , please make sure
the Wet Air outlet is far from Regeneration Air Inlet and the Process Air Inlet
is far from the Dry Air Outlet.
It is also recommended to minimize the length of the duct used. As longer
the duct s are , the performance of the machine will be affected. The Dry Air
outlet of the unit can be fitted with a Volume Control Damper to regulate the
airflow volume when necessary. The damper can also be installed at the wet
air outlet, if you would like to reduce the dehumidification capacity.
