Dehumidifier ML420-MLT1400
5.3 Airflow check and adjustment
To obtain the design performance, the dry air and reactivation airflow dampers must be correctly adjusted in
accordance with the rated airflow, see section
If necessary, contact Munters for assistance concerning installation and settings. Munters contact addresses
are provided on the back cover of this manual.

CAUTION!
UTION!
UTION!
Incorrectly set process and reactivation airflows can cause the unit to malfunction.
Any damage to the unit resulting from incorrect adjustment of the airflows can invalidate the warranty of the unit.
The unit must not be run for more than a few minutes before setting up the correct airflows.
1. Adjust the dampers installed in the dry air outlet and reactivation air inlet ducts to the correct rated
airflows.
2. Start the dehumidifier and run at full power for 8 minutes to allow the reactivation heater to reach its
normal operating temperature.
3. Verify that the temperature difference between the reactivation inlet air and the reactivation temperature
is 95 °C (tolerance limit ±5 °C). If the temperature difference lies outside of the 5% tolerance limit, the
reactivation air damper can be adjusted in small steps until the reactivation temperature is within the
specified tolerances. Allow the temperature to stabilise after each adjustment.
Example:
Inlet air temperature = 15 °C
Reactivation air temperature = 110 °C
Temperature increase = 95 °C
