First-time Commissioning
The unit must always be commissioned for the first time by a service technician from your Condair
representative, or by personnel who are well trained and authorized by the customer. For this reason, this manual
only provides an outline, and not the details of the commissioning protocol.
Outline:
1. Inspect the mounting of the unit.
2. Inspect the ducts for the reactivation air, process air, and wet air.
3. Inspect the electrical installation.
4. Configure the Condair DA Series Desiccant Dryer through the dehumidifier controls.
5. Conduct any applicable performance tests, including controls.
6. Fill out the commissioning protocol documents.
To commission the Condair DA Desiccant Dryer:
1. Ensure the following:
a. External disconnect or isolation switch is preventing the mains power supply from
powering the unit.
b. The mains supply fuse is appropriately rated.
c. Dampers (in reactivation air and process air ducts) are open.
d. Ducts are clean and unobstructed.
e. There are no foreign objects in the unit (including electrical cabinet).
f. Air filters are clean and installed properly.
g. Fans can rotate freely. Fans can be accessed by removing the safety panels from the fan
housing. Ensure that the safety panels are reinstalled.
h. Rotor belt tension is at 15° deflection. The belt will stretch over time, so tension should be
adjusted during maintenance.
2. Close the external disconnect, or isolation switch, to supply power to the unit.
3. Check that the three (power) phases are live by inspecting terminals L1, L2, and L3 in the unit.
The main page on the touchscreen should be displayed and the unit is on STAND BY (the unit

a. Tap the Unit On/Off button on the touchscreen to the
ON

The fans should run and energize to full speed. Ensure that there are no major vibrations during this time.
6. Stop the dehumidifier by tapping the touchscreen and setting the Unit On/Off button to
OFF
. The
reactivation air fans will continue to run. Wait 6 minutes for the fans to stop.
