Connecting CDU Cabinet to CDM

the lower hose connects to the return CDM (red). Place the provided EPDM gasket between the flanges
on the hose and the CDM and install the Tri Clamp locking ring.

Mount Ventilation Tube for Reservoir
To secure atmospheric pressure, a venting tube must be mounted to the Quick Connector on the rear side
of the CDU cabinet. Remove the protection caps from the quick connector and ventilation tube, then
mount the tube as shown below.
The ventilation tube must be disconnected during transportation and should only be mounted at finale
location. When connection is complete, route the ventilation tube and the drain tube inside the rack down
to the floor.
If there is a water leak in the CDU cabinet, the drain will drain from the end of the drain tube. Please
prepare the drainage facilities at the facility side.
