Water-Under-Floor Sensor
NOTICE!
Risk of clogged or leaking drain lines and leaking water-supply lines. Can cause equipment and
building damage.
This unit requires a water drain connection. Drain lines must be inspected at start-up and periodically,
and maintenance must be performed to ensure that drain water runs freely through the drain system
and that lines are clear and free of obstructions and in good condition with no visible sign of damage
or leaks. This unit may also require an external water supply to operate.
Improper installation, application and service practices can result in water leakage from the unit.
Water leakage can result in catastrophic and expensive building and equipment damage and loss of
critical data center equipment.
Do not locate unit directly above any equipment that could sustain water damage.
We recommend installing a monitored fluid-detection system to immediately discover and report
coolant-fluid system and condensate drain-line leaks.
The unit accessories are equipped with a water-under-floor sensor, connect one end of the sensor to
