Leveling requirements
Adjust the MCS leveling feet so that the unit is level.

Condensation management
Any condensation that forms is collected in each individual cooling module and is taken through a discharge
tube to a condensation tray integrated in the base assembly. Where multiple cooling modules are used, the
condensate discharge tubes are connected to one another using quick connectors. Any condensation that
occurs is then removed through this series of connections to the condensation tray.
When the specified condensation level in the condensation tray is reached, a sensor activates a pump that
pumps the condensation into the return system. A further discharge tube runs out of the system from
condensation tray to drain excess fluid if needed. This hose should be connected to a collection system or an
external drain.
To ensure reliable drainage:
• Ensure no kinks form in the drainage hose.
• Do not reduce diameter of drainage hose.
• Route the drainage hoses so that they always run downhill.
To avoid excessive buildup of condensate and to conserve energy, consider raising the cooling water
temperature to the necessary cooling capacity.
